Borax, scientifically known as sodium borate, has been used for decades as a laundry detergent and insecticide, but lately some people have wondered about its safety. It’s often recommended as a safer alternative to over-the-counter laundry products, because it’s not stuffed with unknown fragrance and other chemicals.

But now some are debating that idea. An article last year by Rebecca Sutton, Ph.D. and senior scientist for the Environmental Working Group (EWG), stated that Borax is not a green cleaning ingredient, and that the EWG does not recommend using it to clean your home.

You may like to use borax when doing laundry—is it safe?

What is Borax?

Borax is a white, powdery, naturally occurring mineral that is also called sodium borate, sodium tetraborate, and dosodium tetraborate. It has been used in cleaning recipes to help boost stain-fighting and grease-cutting power. Many use it to make their own cleaning products, and it’s also found in personal care products like diaper creams, some hand soaps, and some tooth bleaching formulas.

Is it Safe?

What's Your Skin Score Quiz

Though generally considered safe, there are some concerns with Borax. The first is that it is an irritant, and can hurt your skin and eyes. This is especially true with young children, who may transfer it from their hands to their mouths if they find it nearby, so you want to keep it out of reach.

Some of the other concerns, however, are a little difficult to root out, because many of the studies that show the ingredient to be toxic aren’t looking at borax—they’re looking at boric acid, which is slightly different. According to Sutton, men working in boric acid-producing factories have a greater risk of decreased sperm count and libido. But they were exposed to high amounts of boric acid—not small amounts of borax.

The Environmental Protection Agency states that boric acid and borate salts have low toxicity by the oral and dermal (skin) route. Higher doses, however, have been linked with seizures and convulsions, and infants have been accidentally poisoned by boric acid or borax. Neither has a connection to cancer, however.

There was also some evidence in EPA tests that borax and boric acid can cross the placenta, affecting fetal skeletal development and birth weight, but again, this was at high doses. The Material Safety Data Sheet (MSDS) on Borax lists it as “slightly” irritating to skin and eyes, and states that chronic exposure can produce eye irritation, cough, and skin rash. There is no evidence that the salt accumulates in the body, however. The MSDS rates it as a health hazard of only 1—the same as baking soda and salt.

Bottom Line—Your Choice

I think overall, as long as you keep your children and pets away from it, you’re okay to use Borax in the home. Of course you need to rinse it off well if you use it for cleaning, and make sure your clothes are well rinsed before putting them on children. If you have cuts or scrapes on your hands, wear gloves or avoid using borax until you heal.

The EWG recommends omitting borax from your homemade cleaning products. You can use baking soda instead, or vinegar and lemon juice. You can check out their “green cleaning tips,” here.

    My father has false teeth. The ‘Holdtite’ powder made in Italy that helps keep the plate in place is made of ‘Acacia, Karaya and Sodium Borate’ The latter is borax.

  2. angela says:

    Oh whats the problem, big corp don’t want us making our own laundry soap now? This is disgusting, what liars, people aren’t snorting borax. it is in all kinds of products, even eye wash, guess it isnt that dangerous.

  3. Melissa says:

    I’m with Angela. It’s just another way to scare people. It’s a mineral from the earth. Bounce dryer sheets are used to repel rodents and insects. What does that tell you?

    I have been studying this because May people are getting great results ingesting small amounts. So don’t just stop at this site. This is one:::Re: Multiple Cures from Diluted Borax

    [YEA] 06/26/2014: Michael from Sydney, Australia: “OK, just the facts. I’m taking an almost homoeopathic dilution of borax; 1 rounded teaspoon dissolved in 1 litre of water. Then take 2 to 3 teaspoons per day of this already dilute solution. Much less than I’ve seen recommended here but it works a treat for me.
    On the first day I noticed nothing at all, including no ill effects.
    On the second day a thick coating appeared on my tongue, clearly this was yeast being chased out of my system. I also noticed that my skin was much softer. I’m male so I wasn’t looking for this but it certainly feels healthier, so yay! In the evening I felt very tired and had to sleep; I have had insomnia forever so this was surprising.
    On the third day the many discoloured patches on my skin disappeared – not faded; gone! I’ve had these patches for about 20 years and I’ve known they were fungus for all that time and now they are completely gone. Also my hair feels softer and thicker.
    Sometime during all of this I noticed that the osteoarthritis in my knees was diminished to such a degree that the pain of walking was almost gone.

    It is now the 4th day since I started taking borax and the gains continue unabated. My tongue has cleared up and I’m even losing weight. Lots of weight. In 4 days.

    Can this be happening? The sceptic in me wants to reserve opinion but the results so far are so breathtaking that I had to post this. The main point I wanted to make was the extremely dilute solution I’m using, and yet it still works. So, if you are have trouble getting your head around ingesting borax, perhaps you could try this method too. By my reckoning you’ll be taking roughly 1/200th of a teaspoon of borax per teaspoon of liquid and you can barely taste it. Hope this helps.

    Good luck all.”

    Yeah, I agree the others. This is just another attempt from big laundry detergent corporations to stop people from making their own detergents. Borax is about $3 and the same amount of the other brands cost between $12 & $18

    Yeah, I agree the others. This is just another attempt from big laundry detergent corporations to stop people from making their own detergents. Borax is about $3 and the same amount of the other brands cost between $12 & $18. Plus, where are the stats? Borax has been used for over a century. I bet if I put today’s leading laundry detergents made on my skin it would do more damage.

  7. Chris says:

    I came here looking into ingredients found within my eye drops….
    WTF, ROHTO “Cooling EYE Drops” have both BORIC ACID AND SODIUM BORATE…

  8. Stan says:

    Many comments here endorsing the use of Borax or Sodium Borate as an alternative to commercial detergents. I too endorse natural alternatives to manufactured cleaning solutions. Several studies have linked susceptibility to Multiple Myeloma (cancer of blood and bone in humans) to ingredients contained in manufactured clothing detergents. To improve their cleaning ability, and market share, many of them have included questionable chemicals that do the job…..but at what expense? Can anyone say they’ve studied the multitude of chemical interactions that might cause harm to humans? No! After the diagnosis of my sisters condition, Multiple Myeloma, all of our family was involved in finding the cause and treatment. All MM patients die within months to 8 years of diagnosis. She passed away at 52, 14 months post diagnosis. The only common item we could find was the use of a clothing detergent (T—) that contained chemicals thought to contribute to the susceptibility. Of course, there is the question of genetic susceptibility to certain conditions that cause cancers.
    Personally, I’ll stay with natural cleansing and limit my exposure.

  9. Carly says:

    I think this is very stupid so just compare the Borax to a different detergents:-)

  10. Terry says:

    Watch… get a cut on one hand, get the same cut on your other hand.
    Put anything you want on one and Borax Powder on the other.
    Cover both with a Band aid and leave for 3 days.
    Borax will win every time…
    Enough said…

    It was suggested that I use Borax in my dishwasher, (1/4 cup tossed into the machine before the cycle starts. I’m wondering if this would be harmful to my machine or to my family. Thank you.

  12. It is very interesting to read more about Borax as many people know that it can be harmful but the question is how harmful and what quantity it should be in order to be harmful? I use Borax a lot for cleaning purposes and I am very careful when using it around my pets and children. I have never had any issues with it and it is amazing as a cleaner! I can’t imagine cleaning without Borax. Honestly, I think that using toxic cleaners is much more dangerous for our health than using Borax! Thanks for the informative and thorough post!

    I use borax to wash fruit and as a tooth paste mixed with equal parts baking soda and coconut oil. This combo works as a facial cleanser. Be careful. Of false environmental groups. Just follow the money. Government agencies. Work for chemical corporations.

  14. Barney says:

    The EPA and the FDA CANNOT be trusted to give us correct info. They essentially be bought off by BIG CORP! The FDA banned the use of Borax in foods, but said OKEY-DOKEY to ROUNDUP in our food. The reason behind the “possible danger” is the pH of Borax. Children’s skin is super sensitive to high alkaline, and can cause severe blistering or burn. Just use your head, and dilute. You would want you child to get a big mouthful of orange oil either. The high alkaline was the problem with the Mr Clean Magic Erasers.

  15. Louise says:

    In including it in a formula for home-made laundry detergent, the recommended usage would be the equivalent of approximately 1 + 1/2 teaspoons per wash load: that’s way below the need for any “safety concern”.
