That sudsy product may last long on your shelf, but what’s the price?

Also called MIT, this ingredient is often found in antibacterial products.

Unlike some synthetic chemicals, however, this one isn’t just a mild skin irritant. A recent study found the chemical may actually be linked to nerve damage, and it’s also known to be toxic in several other ways.

Let’s figure out how to avoid this one!

What is MIT?

What's Your Skin Score Quiz

This ingredient is a powerful biocide. That means it’s a chemical substance that can control or kill harmful microorganisms. It works well as a preservative in products like shampoo and body care products, helping them to last a long time on the shelf and in your bathroom cabinets without becoming contaminated with unwanted bugs, bacteria, and fungi.

MIT belongs to a group of similar compounds called “isothiazolinones,” which also include the following chemicals:

  • Chloromethylisothiazolinone (CMIT)
  • Benzisothiazolinone (BIT)
  • Octylisothiazolinone (OIT)
  • Dichlorooctylisothiazolinone (DCOIT)

You’ll find MIT and chemicals like it at low concentrations in “rinse-off” products like shampoos, conditioners, hair colors, body washes, laundry detergents, liquid hand soaps, bubble bath, hand dishwashing soaps, and shampoo/conditioner combinations.

What are the Concerns?

The biggest concern with this ingredient came to light when researchers conducted two recent laboratory studies on rat brain cells, and found that MIT caused damage to those cells. The researchers stated, “a brief exposure to methylisothiazolinone, a widely used industrial and household biocide, is highly toxic to cultured neurons….” The scientists went on to state that these toxic effects had been reported previously, and because of their widespread use, the consequences of chronic human exposure need to be evaluated. What was most concerning about this study was that the exposure was only 10 minutes long.

What did the cosmetic industry say about this? The Cosmetic, Toiletry, and Fragrance Association (CFTA) issued a response stating that MIT is safe as it is used in cosmetic formulas because the exposure is so low. Indeed, in 2004, the European Scientific Committee on Cosmetic Products and Non-Food Products Intended for Consumers (SCCNFP) suggested that companies limit the maximum concentration of MIT to 0.01 percent, or 100 parts per million (ppm). U.S. companies, however, are not required to follow this guideline.

Other Concerns

Another study found that exposure to MIT caused dermatitis, while a recent 2012 study found that brief exposure to MIT is toxic in low concentrations during neural development, increasing the risk of seizures and visual abnormalities. “Our findings,” stated the researchers, “combined with the fact that the long-term neurological impacts of environmental exposure to MIT have not been determined, suggest a need for a closer evaluation of the safety of MIT in commercial and industrial products.”

The Environmental Working Group (EWG) also states that MIT is a skin sensitizer and irritant, which means that it can cause contact allergies.

Bottom Line

Cosmetic companies defend their use of this ingredient by stating that they use very low amounts, at around 15 ppm. They further claim that because the ingredient is in “rinse-off” products, any dangerous or toxic effects are washed down the drain. Meanwhile, you have a bacteria-free formula that lasts a long time on your shelf.

I don’t know about you, but that doesn’t really make me feel any better about using this stuff. The scientists themselves are saying we need more research to determine safety—in my book, that means, “stay away until we know more!”

Here’s another quote from the first neurotoxic study I mentioned:

“Unfortunately, we have little or no information about the potential negative impact on the brain for many commonly used substances….The long-term consequences of low-level chronic exposure to isothiazolinones on the central nervous system have not been investigated.”

Besides, we don’t need these toxic, skin damaging preservatives in our products.

Do you avoid MIT in your products?

  1. Peachie Smith says:

    I love WEN hair care, but very shocked and disappointed to learn that it contains this toxic ingredient! Don’t know what to do now. Let’s put pressure on these companies to “get back to nature” ingredients.

  2. Mike says:

    Dove soap contains this ingredient also.

    • ally says:

      FYI Mike Dove soaps do not contain this ingredient i use dove soap, body wash, and lotion daily and have checked ingredients and not one contain this in them.

      • Adrianne says:

        Dove body wash in the bottle does contain MI. I’ve written the company to disclose the ingredients in the bar soap but their reply neither confirmed or denied so in the absence of the truth, I plan never to use it again. If you are using it and not getting a skin reaction, then perhaps you don’t have an issue with MI. I plan to avoid it to keep the burning and blistering away.

    • Barb says:

      Dove Purely Pampering Shea Butter Body Wash
      has Methylisothiazolinone in it.

  3. crystal says:

    Nivea lotion and products also contain this

  4. beth ann trudeau says:

    I was recently tested for many chemical and the Allergist was amazed at the amount of positive results. I have gone through all of my cosmetics, including shampoo, face wash, soap, toothpaste, conditioner baby wipes, dish soap. hand soap and laundry detergent. Below is a list of products that I have found to be Me and MCI free:
    Tressome Deep Cleaning shampoo
    CVS conditioner
    Tone soap ( available at Walmart )
    Crest Total toothpaste
    Walmart brand Baby Wipes

  5. Continuation of above post…..
    Clorox Green Works dish soap Do Not use Seventh Generation Products- loaded with MCI
    Soft Soap Soothing aloe vera hand soap

  6. Ernest B. says:

    I have also tested as very sensitive to MCI. CeraVe moisturizers and cleaners are what my dermatologist recommended. Also many Trader Joe’s cleaning products seem to be MCI free.
    Watch out for sunscreens – many have MCI. Coppertone Sensitive seems to be okay but always read the label to double check.

  7. B says:

    What if I find a product with Methylpropional in it, is it still safe for me to use as I have diagnosed with MCI as a main and small traces of MI?

  8. Stacy says:

    My daughter has had a rash around her mouth off and on since May of this year. We finally got in with an allergist & had testing done to find that she has several food allergies but the allergist indicated it may be something else since the rash was localized around her mouth. He got us in with a dermatologist. She asked what we use to clean my daughter’s face and I told her that we use baby wipes to clean her mouth and hands after she eats. She told us that she has heard of increased allergies to baby wipes because of Methylisothiazolinone. Of course we have been using Huggies “Natural Care” and that has it in there. Also, Dove body wash, which we were told by her pediatrician to use because it was hypoallergenic, contains Methylisothiazolinone. The rash has gotten dramatically better in just two days of not using the wipes. I am throwing out every thing we have in our home with that ingredient!

  9. Rose says:

    Hi, I’m from the UK and we have an MIT problem here, too. Do you know if it’s something that has recently been added to products, or is it something you can develop an allergy to? I used to be able to use loads of products, and now I’m reduced to just a few brands – same with cleanser, face cream etc. What makes me mad is that it’s in products that claim to be for sensitive or dry skin! Ie Nivea dry/sensitive facewipes, Dove shower creme, Klorane shampoo. Plus it’s obvious that there are alternatives seeing as other companies don’t use them!

  10. Lisa says:

    I’ve just been diagnosed with an allergy to Methylisothiazoline (as well as Peru balsam, nickel and fragrances). Has anybody found products that don’t have these substances? I’m looking particularly for body lotion, shampoo, soap and facial moisturizer. Thanks for any help!

  11. Brenda Roth says:

    I have been struggling with contact dermatitis for one and 1/2 years. After 2 derm doctors, 3 different prescription creams, taking Zyrtec and/or Benadryl daily, I just found out about MI in Huggies baby wipes which I use on my face. The dr’s had no idea what I was coming in contact with so I started googling everything I use. Turns out the wipes were the main cause. I have had facial rashes, problems with my eyes and lids puffing up, itchy face and neck so bad that I have missed work due to what I looked like! A freak! Found out the hand soap, Method foaming soap, contains it and also my shampoo, Loreal, and my laundry soap, Purex. Why is this ingredient allowed in products? Why don’t derm drs know about it? I am scheduled for allergy testing in a couple weeks but after 2 days off wipes, I am already clearing up.

  12. Jane Schofield says:

    I have had over a month of swollen eyes, swollen neck, hives, red blotchy skin and the most appalling itching imaginable. I have been treated with heavy duty medication (including steroids) in the belief this was a penicillin allergy. All the while I had continued to use Nivea lotion to cool and ease my skin, because I have used it for 40 YEARS and I trusted it! Eventually found out by chance that this was the cause of the entire problem. I have the bottles from before and after the new formulation and there is no indication whatsoever that the formula had been changed. I am angry as I feel so betrayed (apart from losing a month’s income – I sell healthy apple juice at this time of year, but was unable to go to any event that involved meeting my customers, for obvious reasons.) I don’t have toxic shit in my house (all natural paints etc) or my food – and I am furious that I have been hoodwinked into slapping it onto my face……

  13. Indra says:

    Ok so is it only allowed to be in wash off products? It’s in some of my Aveda products that are not wash off like their sensitive moisturizer and their hydrating mask which your skin absorbs in about 10 minutes so you really don’t wash it all off. I think a lot of companies replaced parabens for MIT.

  14. Cheri says:

    This has just come to my attention and disturbs me so. On one level because I am a hairstylist in the beauty industry and on the second level because it seems to be affecting one of my 3 children. I have a five year old that was diagnosed with asthma and severe allergies at the age of 15 months. So since then I have only used hypoallergenic and free and clear products in my home and for my children. I also can be sensitive to smells so I stay away from anything perfumed. However he is not the child at concern right now. It’s my 3 year old daughter who has never shown allergies thus far. Several months ago she began itching head to toe and began breaking in a scaly red broken rash around her eyes, creases in her elbows etc. she is also a girl who loves washing her hands, soap, washing her hair and so on…and with a baby still in diapers we still use lots of baby wipes! Already knowing the routine with my oldest son and everything that we already use I believed to be the most gentle I have been at a loss to what was making my poor daughter absolutely miserable. I plan to investigate this more and look into how I can Pursue this further!

  15. Karron Smith says:

    I have just discovered that I have this allergy after a summer of hell. As I live in Spain you can imagine how bad it was as I needed sun cream everyday, I could not work out what was happening and had to have steroids to take down the swollen eyes. I finally had patch testing and it was confirmed. I have found that Gliss and Fruictus shampoo and conditioner dies not contain MI but I am struggling to find a sun cream without it, any suggestions?

  16. Sarah says:

    I started itching terribly everyday for almost two years. I didn’t know why. All I know was that I was super-itchy after a shower, after using anti-bacterial wipes, cleaners etc. The itching was all over my body and head, unbearable, and the only way to stop it was to take allergy pills like Allegra-D every single day. No doctors could find out why. Then I started using shampoos that did not have any preservatives, likewise soaps, and stopped using commercial cleaning products, especially Clorox stuff. I changed the laundry detergent to natural formula one too. Suddenly my itching disappeared. I am pretty sure it is this chemical that was causing this severe hives. But I am worried that there might have been long term damage to my health.

  17. ally says:

    I started using a St Ives body lotion and my whole body broke out i thought maybe it was my sensitivity to perfume fragrence so i switched and stated using palmers cocoa butter formula and that to made me break out i then switched to dove which didnt make me break out so i compared the ingredients in the palmers and st ives lotions with the ingredients in the dove because if the 2 were irritants there would be an ingredient in them that the dove lotion didnt have i then found that this “MIT” or whatever it is in the two but not the dove or vaseline lotion i used i did some research and found this i will be sure to avoid products with this stuff in it absolutely terrible

  18. Tiff says:

    Ally – Dove has this in some of their body washes and shampoos. I had rashes for over 4 years and went to many doctors…finally to find I am highly allergic to this ingredient. I am finally happy to know what has caused this mess. It was painful and applying this chemical to open rashes is dangerous….
    The UK has banned this ingredient in all items over there. I doubt the USA will ever ban it. Stay away from it!!

    • Charlotte says:

      Here in Canada it is in almost everything and has several other names. It is also found in latex and paints jet fuels radiography printing inks adhesives glues as well as the detergents cleaning products & cosmetic products.All your info has really helped me. I am highly allergic to this preservative and have been hospitalized a few times in the past 3 years.Products claiming to be all natural have this in it. This is criminal. Some of the products I use are Cetaphil gentle cleanser lotions Lubraderm unscented lotionsComplex 15 face cream.

  19. JR says:

    I had issues with my major rashes on my hands for a whole year until I did an allergen test with the dermatologist. Found out I was allergic to MIT and they cleared up after avoiding products as well.

    I use the following products now –
    Dove unscented for sensitive skin
    Organix shampoo (avail at Target) – Sea mineral moisture or Moroccan Argan Oil (have to check all labels bc some scents have the MIT)
    MoroccanOil shampoo & conditioner (avail at hair salons – expensive but great)
    Tone or SoftSoap bodywashes
    Yardley soaps (lemon verbena)

  20. JR says:

    Also..I found that Coppertone Oil Free sunscreen does not contain the preservative as well.

    • admin says:

      Hi JR- please be aware of some of the other harmful ingredients in that Coppertone Oil ! We encourage you to do some cosmetic ingredient research 🙂

  21. Deb Houston says:

    I am allergic to MIT as well, was skin patch tested by my dermatologist in 1999 because of the reaction I had to St Ives “new and improved” formula of face wash that I had been using for years. Back then it was much easier to find products without MIT, but not any longer! I have to bring my own shampoo and conditioner to the salon because I can’t use of their products save for a couple of hair sprays and styling products. Just want to make everyone aware that you ALWAYS have to look for this ingredient if you are allergic to it. Don’t assume that a product that doesn’t have it now will not have it the next time you buy it. It is being used in more and more products all the time. And yes, even in toilet paper!

  22. Anne L says:

    Have been allergic to dishwashing detergent for years–makes hands break out in itchy rash–could not use Johnson’s baby Shampoo on my little ones because it made my hands peel–now I understand it’s this chemical. Just found out Johnson’s has FINALLY removed this chemical from their baby shampoo. My kids are now in their 30s.

    I buy natural hair products at Whole Foods because others make my head itch. It must be the same chemical!

    I’m also allergic to dryer sheets. Stop using them, folks, and see if this helps.

  23. […] there have been issues with it. With just 10 minutes of exposure to MIT it was found to be “highly toxic to cultured neurons” – aka nerve damage and “caused […]

  24. Robin says:

    I suffered horribly for two years because of using Huggies All-Natural Frangrance Free Wipes. It was all over my hands and wiping areas and got so bad I was hospitalized and they brought in Dr. of infectious diseases! He said it was “diaper rash” and on my fingers it was “diaper fingers” ????!!! You can’t have diaper rash if you are not incontinent! It got so bad there wasn’t even any skin left on my bottom. If I sat on a cloth couch or carseat it would rip open and weep copious amounts of fluid…Then I developed a severe reaction to all steroids and I had burns all over my body from it. A biopsy said it was psoriasis. Another Dr, said it was eczema. One day when I was reading on the net I saw a page that said ‘baby wipes causing rashes…’ I stopped using anything with methyisothiazoline in it and withing a month it was gone. And to think my life was made miserable and in writhing pain for two whole years…disgusting. I’m not even bothering to tell the Dr. , let him figure it out for himself.

    • Lolly says:

      Oh Robin, what a horrible ordeal. I am so glad you luckily found out the cause.

      But please, please tell the Doctors. By letting them know, they can help other patients that they will inevitably see in the days and years to come.

      Folks reading this: I beg you to let your clueless doctors know. Other people suffering from this need our help.

  25. JTE says:

    This is a long posting. I don’t know how to tell short stories . . .

    I did not have a specific rash. I saw an article about six weeks ago about baby wipes causing a rash, and just out of curiosity started looking at my dish washing liquid (7th Generation) for the methylisothiazolinone, which of course it contains. Since I am very sensitive to a lot of chemicals, I switched to Planet, which does not contain methylisothiazolinone. My symptoms, though, did not include having a rash, and I only used the dish washing liquid three or four times a week, with just a minute or so of contact, rinsing it off thoroughly after use. Which is why the results were so very weird.

    I had been having visual problems, where after waking up in the morning I had large brown spots in front of my eyes (I thought I was going blind). The spots would clear up after about an hour. My optometrist could see nothing in my eyes that would cause this. I also had a severe pain in the back of my neck, along the spine, that made sleeping very difficult, and was making my hands go numb unless I held my head and neck at just the right angle. The worst symptom, though, was the vertigo. A severe dizziness, causing me to lose my balance sometimes, and making it very difficult to walk. I was thinking that I might have to stop working, the vertigo was so bad.

    So, with that as background, I was very surprised when, after a week of not using the 7th Generation dish washing soap, these particular symptoms started going away. After six weeks, there are no spots in front of my eyes when I wake up, the pain in my neck and spine has gone away (and hands almost never are tingling), and the vertigo has vanished. I am posting this long tale because I have not found anything relating the methylisothiazolinone to these particular symptoms, and if anyone else is having something similar they may want to look through the various liquids and such that they use (even those just used occasionally) to see if this particular chemical has been added to them.

    One other odd thing. My hair had been thinning really badly. I figured it was just from getting older. Since getting away from this chemical, I have noticed a whole bunch of short hairs sticking up along my part (I wear my hair long, with a part in the middle). I have been watching these short hairs very slowly growing longer during the last six weeks. So, there is a chance that hair loss may be part of my symptoms from this. Since losing hair doesn’t hurt or prevent me from working, it almost seems silly to even bring it up, but it is something else I have noticed.

  26. Mariel says:

    Mrs. Meyers contains this ingredient and i’m completely horrified by this. I have been using this product because I thought it was all natural. I will go back to doing my laundry with Dr. Bronner’s magic soap

  27. Adrienne says:

    I had a major allergic reaction last year on my face, around the eye area, and have spent hundreds of dollars with a dermatologist Here in Australia to get patch testing. I had a major positive reaction to both MI and MCI triggered by Loreal Revitalift moisturiser, measurements are usually on a scale of one to three but she said mine was about a seven and one of the worst she had seen. As I had used this cream before with no ill affects it is blatantly obvious the cosmetic industry is slowly increasing the amount they are using, they must be named and shamed until they put our health above their profits. I urge anyone with itchy skin, burning sensations etc etc to get a patch test and report to a dermatologist.

    • Gill Key says:

      I noticed someone referred to having a severe reaction to L’Oreal Revitalift above. I’ve had similar and I’ve now discovered that this is not uncommon – eyes itchy and skin around swollen and very red, along with rashes on neck around mouth, nose etc.

      For the last 6 months or so I’ve been fine. Once I’d got the irritation under control with steroids and emolients, I stuck to very simple skin care ingredients and all was fine. However, I was still puzzled and wanted, if I could, to isolate the cause for certain so that I knew to avoid it in future. As an experiment I thought I’d just try the merest wipe of Revitalift low down on one cheek – and bam, it’s all back again with a vengence – but at least this time I know what to do.

      What I hadn’t put together until yesterday was headaches, numbness up one side of my face, and tinnutus. I had this for months and didnt think it was connected to the dermatitis, but they are all three back again.

      Has anyone else suffered similar reactions and is there any research that I can read up on about this please?

  28. Glenn Marocco says:

    I’m so happy I figured that this was causing these strange eczema like symptoms -first under my eyes(it’s in Bliss products) then after using palmers cocoa butter ( I was fine with it years ago) and I just used Nivea and itched and my legs were swollen- I was on a vacation and just thought it was sun poisoning or reaction to sun screen. I’m avoiding anything with this nasty ingredient !!!

  29. Mary says:

    I had two grand mal seizures out of the blue…. 4 days after a hideous face rash! Horribly allergic to MIT but neurologist said not related!!! Not so sure!

  30. David says:

    Many, if not most, flushable wipes contain this ingredient. I wondered why I was having so much personal itching, pain and even bleeding until I stopped using the flushable moist wipe products. Never again will I use them!

  31. Erin says:

    I am taking baby steps to go more healthy and was curious to see what was in my laundry detergent and it has this as well as a few others that seem harmful-but it came from whole foods! Why does the ecos brand have several preservatives that don’t seem to be good for you?

  32. Natasha says:

    I recently found out I am allergic to methylisothiazolinone. My skin has been bad for years and my chest and back are congested. Can anyone recommend creams or medicine or anything to help my skin normalise and clear up. Thank you. Btw- thank goodness for this website!

  33. Roy says:

    I was using pantene shampoo everyday for years and had little sores in my scalp – only one or two at a time that would vanish after a few days and others would come out in other areas. Stopped using pantene and no more sores.
    Has anyone experienced similar reaction to shampoos?

    • Adrianne says:

      Used to use Head and Shoulder’s dry scalp and after two weeks of an itching nightmare and my back breaking out in whelps, I researched and found that it was in a product I used a great deal of my life. You can get shampoo and conditioner from The Body Shop. Even after two applications, my back is clearing up and my scalp is calming down.

  34. Cynthia says:

    OMG, I’m so grateful for this website. The last three days I’ve had HORRIBLE hive attacks. I’m sensitive to gluten, which can cause hives and thought it could be related but I hadn’t had any gluten in my diet so it didn’t make sense. I thought what’s different in the last three days, oh wait I bought a By Terry face powder (Hyaluronic Hydra-Powder) that I began using the first day of the hives. Just checked the ingredient list tonight and saw methylisothiazolinone. In a face powder! That’s worn all day! How horrifying that this is allowed, how do they get away with that??????

  35. Donna Pike says:

    I have suffered from a skin rash for 3 years not knowing what it was. I had patch testing with a skin specialist – Dr appointments and cortisone scripts – immunology – naturopath x 3 appointments – Skin and psoriasis clique consults- AND NONE ever tested me for
    • Methylisothiazolinone / MIT + also called = methylisothiazoline
    • Chloromethylisothiazolinone / CMIT

    My hands would crack and bleed and ITCH, my thickening skin on my palms would go from the itching and leave behind raw skin that would sting every day. Washing my body and hair would sting, doing house chores would sting, it was driving me insane. I also had the numbness in my hands that someone mentioned earlier, I had the whites in my eyes turn red on morning and went to the Dr who referred me to the eye specialist who said it was allergic conjunctivitis and gave me steroid drops ( which can cause glaucoma).

    I spent thousands of dollars and then just last week I saw a program with a Dr White from LONDON saying that 1 in 10 people are extremely allergic to MIT and CMIT and that was it. I looked at all my products and got rid of anything with MIT or CMIT and I can already see the improvement.

    I also called the companies that had MIT in their products; which were..

    The goastmilk company – they came across like they didn’t care and said the I was the ONLY case that had ever contacted them and complained about getting a rash from their product!

    John Frieda – MIT is in their conditioner
    Babybliss Pro – Argan Oil Resorative Mask – its in there too!
    DU-IT hand cream for dry & cracking skin – yes in there too!
    The goastmilk company – bought the Shampoo & Conditioner from a health food store and because goatsmilk is suppose to calm the skin – but NO!- it was the cause..!

    * I also emailed A CURRENT AFFAIRS & 60 MINUTES to ask them to do a show about these chemicals.
    I sent complain forms to the;-
    * ACCC Therapeutic Goods Administration. 1300 302 502
    * State Health ; 02) 9391 9000
    * NICNAS – National industrial Chemicals Notification and assessment scheme: 1800 638 528.

    If everyone on this site acted, we just might get it out into the public more and save a whole lot more people from the living hell that we have had to endure. No wonder we are all getting cancer! If this is what chemicals do to the outside ~ what are they doing to the inside?

    GO 100% NATURAL – its a must. Apparently NEWWAYS in Australia are chem free to a point and I also found a lady that makes 100 % natural and organic shampoo, Conditioner Make-Up & Skin creams 🙂

    PERFECT NATURAL SKIN: m: 0437 100 490 – all natural!
    SWISS; also have a natural face moisturiser with plantolin.

    Please share your info ~ it may help others more than you know!

      I was using Wen which also has this ingredient and my entire left side went numb tingly. I’ve been to two neurologists who say the shampoo had nothing to do withthenerve damage but they can’t find the source. I’m looking for a dr to help!

      • admin says:

        Hi Kristan!
        We’ve received this question before regarding Wen ingredients. They’ve taken down their complete ingredient list on their website product page (which I find concerning…) I was however, able to find the complete ingredient list searching the web. This is the list I found for the cleansing conditioner:
        Water, Glycerin, Cetyl Alcohol, Cetearyl Alcohol, Stearamidopropyl Dimethylamine, Chamomilla Recutita (Matricaria) Flower Extract, Prunus Serotina (Wild Cherry) Bark Extract, Rosmarinus Officinalis (Rosemary) Leaf Extract, Prunus Amygdalus Dulcis (Sweet Almond) Oil, Aloe Barbadensis Leaf Juice, Hydrolyzed Wheat Protein, Vegetable Oil (Olus Oil), Panthenol, Butylene Glycol, Behentrimonium Methosulfate, Polysorbate 60, PEG-60 Almond Glycerides, Amodimethicone, Citric Acid, Menthol, Methylchloroisothiazolinone, Methylisothiazolinone, Fragrance, Limonene, Hexyl Cinnamal, Linalool, Geraniol, Benzyl Benzoate, Hydroxyisohexyl 3-Cyclohexene Carboxaldehyde, Hydroxycitronellal.C960

        More information on these ingredients is listed here:

    I started with swollen eyes and sores around the eyebrows and put this down to a chemical reaction to having my hair highlighted in the salon, this went on for quite few months with no resolution so I had all my hair cut short (was down to the bottom of my back!) This alleviated the problem, have grown it since and so it is long again, I used Herbal essences hello hydration yesterday, changed from another shampoo and conditioner I was using and lo and behold my eyes started swelling up yesterday afternoon and this morning they are nearly closed and my eyebrows and sides of my face are very itchy and around my lips all crust like. Funnily enough the herbal essences I bought the ingredients were in a language I couldn’t understand even though I speak several, so went on line to look at the ingredients and see where I could have a problem and found a number of websites about this, its shocking that so many people have to go through this and it should be stopped, Now need to travel to find some medication to try and bring this swelling down and hopefully nip it in the bud before it gets any worse.

    I realised over a year ago that I was allergic to these caustic substances, and made sure, after throwing away most of my soap products including, non bio liquid, hand soap and made sure all these items were MIT Etc., free. Back in February of this year I brought fabric softener from LIDL’s and after using it I had all the itching discomfort back. After watching a prog., on TV about these caustics, I checked this product to find it is full of at least three of these. Here in the UK, Coys., have been asked to faze out all these caustic products. The problem here, is that in the EU they are able to legally use 10 times more strength, than here in the UK. As nearly all our Stores are owned by various Coys., from around the world, they are free to import their goods from anywhere in the World. Until this is banned, we will go on suffering, until some ones big wig wife is affected, then Parliament might ban this caustic that is said to affect around 40% of us. Peterkins

    On a whim I chose not to buy my usual Fairy gel tabs but instead chose Bold 2in 1 . It has taken me a couple of weeks to work out why my body is covered in large welts/hives that are itching like mad. Doctors Antihistamine tablets were proving to be useless. Then I realised that MI is in the fabric softener. Wearing my clothes and sleeping in the linen was making it worse day by day. At the very least a warning that MI is an ingredient should be in large letters on the front of the packaging. All this misery for something that should be banned. See the e petition to sign and have the question raised in parliament

  40. I developed a full body rash as a result of isothiazolinone, and am still having issues as it is very difficult to avoid the product when it is not always present on the label, or website, even when it is present in a product. I feel that all ingredients should be listed so that consumers can be aware and make educated decisions regarding their health. I have since started this petition: http://petitions.moveon.org/sign/require-complete-ingredient

  41. Edna foster says:

    My son is extremely affected by these chemicals they have taken from his life and reduced it to his own little “bubble”, unable to wear anything but 100% untreated, no dyes no color treated, white cotton, if u can find true 100# cotton. Most say 100% but then label says 97% cotton 3% ? (poison). He is not able to hug anyone wearing street clothes, unable to invite new toys, clothes or friends in. Shoes, socks, underwear, bedding, outerwear, carpet, paint, laundry soap, bath soap, lotions, furniture, all these basics of life have been made toxic with these chemicals. every environment is a possible hasard because of its wide spread use. These bad chemicals have stolen his life, he 37 with to boys to raise in Michigan, living is tough enough but imagine kid brings in a new toy and you become covered in a rash, imagine no winter coat in Michigan, imagine your son whom you are so proud has a performance 5hrs away and you can’t ride in just any car the interior may be toxic can’t have a rider, they may be toxic with clothes, lotions, fabric softener. I just heard a report eczema is on the raise, is it due to these toxins? This is a man/greed made problem we must get fixed, I am sure there are many more people affected who have no idea yet that it is the same products that they use to make them beautiful that are the poisons

  42. Rebekah Baharestan says:

    I am currently acutely allergic to Methylisothiazolinone with swollen bleeding hands, now diagnosed with allergic contact dermatitis that may be permanent, I have a complete hand disability, unable to work or even brush my own hair due to this preservative. It is a very dangerous skin sensitizer and my life as I once knew it is over- I still have not had one response from companies after filing multiple complaint chemical reaction reports through consumer product safety commission and EPA. Apparently we are helpless here in the US to seek safe chemical labeling measures?

    • robert carlin says:

      I would get an allergy test done. Mine came back as all kinds of things including this topic. For me mostly nitrile products,gloves I was using at work. My hands blistered,cracked and bled to the point of severe pain I’d wish upon no one.I also found out bounce dryer sheets did the same thing that affected my whole body.
      Now after roughly few months of being clear,here I go again.

      Even with the gloves that I had used for 14 yrs my body decided it was time to fight this chemical.amazing to me I change oil,work on cars never wore a glove unless I had to,now I’m changed forever.

      Have you combined a list of products that have this chemical in it?
      If so could you send it to me. magcubs@aol.com

      It is a constant battle for me like now only three fingers are broke out on my palm side nothing on top of my hand.

      Good luck and there are so many products that contain this look at your hand soap,shampoo. Good luck finding out your cause,let me know if you here any news.

      thanks

      • Yes, thank you. I did get an allergy test done, specifically skin patch testing to environmental chemical allergens: positive test results :
        Methylisothiazolinone. Methylchloroisothiazolinone, Octylisothiazolinone. hands are now normal. 1 full year in order to be treated and slowly regain my health and function of hands. allergic contact dermatitis to preservative chemicals is no joke. this was extremely painful and difficult recovery. many many visits and treatments by medical professionals /specialists were needed.

      • Hi, I also suffer with the bleeding cracked hands, rash, bubbles, scars. I feel like I am going insane!! I was diagnosed last year as having a real allergy to these two chemicals. Methlylisothiazolinone and it’s counter part. I purged everything in my home and have gotten products that are safe, but to no avail. I still touch things outside of my home so it’s a no win situation. I am so embarrassed the way my hands look all the time. It’s constant discomfort. Have you found any relief??

    • Deana Slone says:

      Rebekah, my story is identical to yours. I had been using Pantene, Dawn, and O’Keefe’s for years then suddenly my head and hands starting getting a rash, itch really bad, crack, and bleed. I can no longer do dishes without gloves and they make my hands sweat which increases the symptoms. I have yet to find products without this ingredient and would welcome any ideas.

      • Deana Slone says:

        I forgot to mention that I was diagnosed with this allergy by a dermatologist. I am angry that these companies continue to use this ingredient after they have been made aware of the serious reactions people are having.

      • lisa says:

        I am having same problem when i wash up some times thepain is so bad i cry i now wear gloves to wash up but i av found that if u use hand cream then put gloves on .it works for me hope it works for you to .

  44. Rick Briton says:

    Where to start. I reckon I’ve been using products with MI in it for over 10 years and my hair began to thin, and the skin around my ears began to peel. Then my face received a blotch above the cheek and towards the ear so it wasn’t noticeable with longer hair. Then this blotch got a little bigger and it seemed like it was seeping down my face and cause what looks like a chemical burn down my face but I didn’t know what it was so I carried on using the products. My ears kept burning after I washed my hair it was crazy annoying. Then the blood vessels in my eyes burst, causing me to get red splotches in my eyes. They would disappear and then a few weeks later come back. I carried on using the products without realising. Then the blood vessels in my eye happened more than often and the splotch on my face throbbed. My ears continued to burn and itch and peel. Then I watched a tv show about consumer goods and they talked about MI, I’ve only stopped using it for 8 months and I’ve had no re-occurrence of blood vessels bursting in my eyes and the splotch on my face seems to have relaxed now. I didn’t know it at the time but I continued to use washing up liquid which would spark my splotch off and I’d wonder what caused it. I now wear rubber gloves when washing up. My ears still peel probably because of the abuse over the years but they don’t burn everytime I wash my hair now. I have to be careful at work too because I’m surrounded by the stuff as well. If that isn’t evidence of cell damage I don’t know what is.

    Je suis tres heureux d’apprendre cette vérité .J’ai appris le danger de cet ingrédient toxique et meme tres toxique par une émission a la télé et dont le Dermatologue de grande réputation de Montréal au Québec le docteur Denis Sasseville a démontré hors de tout doute, les grands DANGER DE CET INGRÉDIENTS TOXIQUE tres bien caché dans beaucoup de nos produits de santé !! Je suis en faveur que le Ministere de La Santé du Québec fasse ARRÊTER TOUT DE SUITE LA PRODUCTION DE CE PRODUIT ET L’INTERDISE DANS TOUT LES PRODUITS D’USAGE COMMUN , car c’est justement dans nos produits a usage domestiques que les grandes compagnies ,pour épargner de l’argent .insère ces poisons dans les produits tres populaires et encore une fois s’enrichissent au détriment de notre santé a tous ”Pour eux l’argent est avant tout le but de leur production et la santé du peuple ils s’en foutent royalement .Un recours COLLECTIF POURRAIS MEMEM ETRES ENVISAGÉ , AFIN DE LES ARRÊTER et les faire réfléchir et pensé VERT PLUTOT QUE MONEY !!!!!!

  46. Joy says:

    Just been to local farmers shop and came back with washing up liquid which contains this stuff. I will take great care not to touch the water with it in and rinse everything under the cold water tap. Lidl stuff all contain this and its made in Germany so perhaps not forbidden there. It should come off the market entirely and there has to be a stop to testing this vile element on animals.

  47. Jeff says:

    I am most concerned about all biocides . I am the water treatement person at my place of employment . I recently had a significant dose of highly toxic Ashland biosperce 271 one my hands, partial face. Took a bath to rinse and it burned horribly.
    The ph level of biocides are 13.7 ! Now 7 is water. And 1 is acid. So 14 being the highest 13.7 is extremely high base low acid. Meaning it will absorb in your skin fully almost immidiatly! This is highly costing . Had a Freind get( dosed) and it went through skin to bone . He died from leukemia In less than 1 year.
    Granted doses in Water and products is low but it does not dissipate from organs quickly. It builds up. I wish I had help!

  48. Donna says:

    I have been recently patch tested and isothiazolinone. Is my problem! I am just in the begining stages of trying to find my problem products. I need a laundry soap and fabric softener any ideas? I’m using the Kirkland clean and clear I know that is a problem! Help?

  50. Mary Bennett says:

    Just used Clarins rejuvenating creams (Serum and moisturiser) never again my face has erupted into a very red lumpy and itchy mask, and very sore. Both these products contain Methylisothiazolinone (MI). Should be band.

  51. marri says:

    I recently used a hair product, shampoo specifically produced by OMX,
    it left me with my scalp burning and blistering similar to burns, I ended up going to a local emergency room where I was prescribed steroids and antihistimines. over 14 days later my scalp is still red and my skin is peeling and sore to touch, thankfully I haven’t lost my hair as of yet. I used no other new products so I know it to be this only after emailing the company and doing some online research I found it has Methlchloroisothiazolinone which can cause symptoms as I described here is no warning label on the shampoo. I am currently waiting for a response from the company as I write this, if I have no response I will be seeking legal advise.

  52. amber says:

    i just had the allergy test and i am allergic to mi mic where my eyes and face swell up and i get blisters when in contact

  53. Fiona says:

    Hello again, well, I just called “Nature’s Organics” and I am being given a refund (in the form of a credit in the supermarket I bought it from).

    The woman I spoke with didn’t even “blink and eyelid” when I told her, which makes me think I may not be the first person to point this out to them! Shameful negligence.

  54. Mike R says:

    I had suffered for over a year to extreme dermatitis on my hands within 3 months of my son’s birth. I had no idea of what was causing it and neither did my dermatologist. Only after trying every steroidal crème and lotion available did my allergist suggest I get tested for household products. I was tested for three days and had an extreme reaction to MIT and similar compounds. The problem is that MIT is not readily labeled on most soaps. A quick search of the internet provided a list of almost every product I used at home and the wipes I used on my son to wipe him between diapers. As long as I avoid products containing this harmful chemical my hands stay clear. You always have to carry your own soap with you for use in bathrooms when you have this allergy. Companies need to remove this from the mainstream products!

  55. Used Trader Joe’s “All Natural” moisturizer blend for years when, suddenly, my skin all over my body began to burn, like someone had bathed me in acid. Turns out me they had suddenly decided to add MIT to their product, which is anything but “natural”.

    Broke out in blisters within minutes, despite rinsing myself in the shower as quickly as I was able. The blisters, over the course of a few days, became infected, due to scratching while sleeping, and I was forced onto antibiotics due to the resulting bacterial infiltration.

    The doc recommended Eucerin for future skin health. Ignored her and got colloidal oatmeal. Used that for several weeks and cleared up my skin. Ran out and, at the drug store, saw the Eucerin. (Didn’t know at that point that it was the MIT…just knew that I was suddenly not ok with my old brand, which was full of herbs and fliowers, all potential allergens.)

    Well, you can guess that my old brand with the new ingredient and the Eucerin had exactly one ingredient in common: MIT. That is the sole commonality between the two brands. So, here I sit, once again covered in fire and blisters, thanks to this awful chemical creation.

  56. Hailwy says:

    After reading a book by Paula Begoun, I have avoided many skin care products and hair products because so many of them contain “bad” ingredients. I find it funny how so many companies put “paraben-free” or “alcohol free”, “sulfate-free” and yet it’s quite rare (in Alberta, Canada at least) to find products that are fragrance free. And yet that is a skin irritant. Supposedly it’s not the worst thing ever as long as it’s in a wash off product, like cleanser or shampoo and such, but a lot of non wash out products have it as an ingredient. I always thought Lush was quite good for products, but almost everything has fragrance in it, I don’t those are “natural fragrances” either. But anyway, my current shampoo has Methyl…. I’m not going to bother spelling it, in it and I thought maybe it was safe. But I am going to finally try Paula’s Choice shampoo and conditioner. They are $16 each but they have nothing harmful in them. Well, I should be honest, some of her products have parabens but according to her research they aren’t harmful in the amounts used. And I have decent skin for having combo skin so I personally trust her.

  57. Kelly says:

    I have recently become aware of these chemicals due to a severe reaction, my neck is extremely red raw and itchy. My face it dry and cracked and all from using inecto hair conditioner, the product is suppose to be natural Ingredients. Lesson learnt!

  58. Margaret says:

    have been using an anticiotic hand soap to remove the conditioner that I use after shampooing my hair, I rinse it off and then put my own conditioner on called Aussie. It has worked very well until lately as late as a week ago I rboke out with a very bad rash on my back. I went to the dr. and he thought it might be something from outside workin the yard.
    I was on a strong steroid to get rid of the rash. I became alergic to the steroid and had to stop within 2 days.
    I don’t know if washing my hair with the hand soap was the cause.

  59. Jill says:

    I found out that many household paints (Behr among many) including low toxicity “green” paints, most markers and children’s craft paints also contain MIT. My daughter is allergic and her hands are still affected because of the school art supplies. The ACDS CAMP website is a great resource for cleaning supplies and cosmetics if you’ve been patch tested. Your contact dermatologist can give you access codes. But for things like paint and inks, contact the manufacturers.

  60. see Facebook public group for more people severely affected by isothiazolinones. ‘Allergy to Isothiazolinone, Methylisothiazolinone and Benzisothiazolinone’

  61. see Facebook public group for more people severely affected by isothiazolinones. ‘Allergy to Isothiazolinone, Methylisothiazolinone and Benzisothiazolinone’ . There are product discussions for assistance finding safe products free from isothiazoilnones as well as discussions on products that have caused severe reactions containing isothiazolinones . ( see files section) Cosmetics products : the two isothiazolinones currently approved the US used in cosmetics are : Methylisothiazolinone ( MI /MIT ) and Methychloroisothiazolinone ( MCI/ CMIT) only.( MI and MCI have been banned from future formulated leave-on products in the EU effective year 2017. The additional isothiazolinones : Benzisothiazolinone ( BIT) and Octylisothiazolinone (OIT) are also found in cleaning and household as well as automotive and latex paint type products along with MI /MIT and MCI /MCIT

  62. Has Resque been Banned? It has Methylchloroisothiazolinone, & Methylisothiazolinone in it?

  63. Kristen says:

    I only use “natural” products. This doesn’t seem to mean anything when it comes to Methylisothiazolinone (MI). I was diagnosed last year with an allergy to MI and nickel by an allergist after I came down with itchy, red, sore spots on my face, eyebrows and hands. At first the doctors had told me I washed my hands too often. Then they told me I might have lupus. Then an allergist did a skin test and told me that I was allergic to MI and that this was an epidemic allergy. It was in the Trader Joe’s lotion I had been using everyday for years. And it was in our Seventh Generation laundry detergent, dish soap, spray cleaner, etc. It is a common synthetic preservative in so-called “natural” products.

    I got rid of all of those products, but still have a hard time finding products that don’t have it. I now use Planet dish washing liquid and Planet laundry powder (but the Planet laundry liquid has it!), and I use Greenshield Organic spray cleaners. I haven’t found a good lotion or consistent hair conditioner, etc. But even my son’s school uses soap with MI (Dr. Bronner’s) and I can’t even share a hand towel with him or touch his hands immediately after school.

    I have tried every kind of moisturizer, including plain olive oil and coconut oil, but nothing helps my finger. The red, itchy, horrible rash centers on the right, middle finger and spreads out from there now. The finger is now swollen larger than the other fingers as of a few months ago. The rash is no longer on my face, but occasionally my eyebrows itch and sometimes there is a new patch on my forehead or leg.

    I really don’t know how to stop it or to fix it. I can’t seem to clear it up all the way no matter what I do. It hurts, it itches and it looks terrible.

  64. Suzanne says:

    I could almost write a book on this chemical allergy! I have a sever allergy to it and another chemical. It took finding the right doctor that too the time to help me. Mine was not from wipes but from lipstick, moisturizers and so MUCH more. It in so many thing but most commonly in wipes. Please be away it is also known as CI=Isothiazolione, Kathon, Kathon CG, Kathon 886, MCI, and MI . In in 2014 this chemical AND Colophony, also found in MANY MANY products were the new emerging allergies of the year. This past Memorial Day weekend I ended up in the emergency room from a severe reaction to sun screen. It is very painful and the more times you are exposed the worse the reaction. Please feel free to share this post and help protect yourself and children.

  65. Alwosta says:

    Nivea lotions contains this toxic ingredient which may causes cancer.

  66. does simple wipes from unilever brand contain meththylisothiazolinone or methycloroidothiazoline or has it been added recently.m lupton.

  67. Angela says:

    I have had methylisothiazolinone allergics reactions. It was at biomiracle makeup cleansing towelettes and Neutrogena healthy skin , liquid makeup. That is incredibly because those products say they are “hypoallergenic” and “healthy”.
