Ingredient Watch List: Benzyl Alcohol, Another Irritating Preservative Unsafe for Infants

Benzyl Alcohol

Ready for another synthetic, potentially harsh preservative? Benzyl alcohol is actually a natural ingredient. Many plants, fruits, and teas have it as a component, as do essential oils like jasmine, hyacinth, and ylang-ylang.

Unfortunately, in most personal care products, you're not going to find the natural version. Instead, manufacturers make the synthetic version in the laboratory by mixing benzyl chloride with sodium hydroxide. It's cheaper that way, but not as wholesome, as benzyl chloride is very irritating to the skin. It can also be particularly dangerous to very young children.

Benzyl alcohol was linked to the deaths of
16 premature infants in the early 1980s.

What is Benzyl Alcohol?

Benzyl alcohol is a colorless liquid that has a mild, pleasant aromatic scent. It's also called an “aromatic alcohol,” and is used as a preservative, as a fragrance ingredient, as the active ingredient in head lice treatment, and as a solvent, which simply means that it's used to dissolve other ingredients to make a smooth formula or solution.

Benzyl alcohol also works as an anesthetic, so it is sometimes added to formulas that relieve itching, especially eye products. Most of the time, you'll find this ingredient in bath products, soaps and detergents, eye makeup, blushes, cleansing products, shaving products, makeup, and blush, as well as in hair, nail, and other skin care products.

Is It Safe?

The FDA has approved benzyl alcohol for use as a synthetic flavoring agent for direct addition to food, as well as an anesthetic in oral healthcare and topical analgesic drug products. The Cosmetic Ingredient Review (CIR) has concluded that its safe for use in cosmetic products, at concentrations of up to 5 percent, and up to 10 percent in hair dyes. The CIR didn't take into consideration, however, the duration of use or the frequency of use when concluding that these levels were safe.

In the European Union, benzyl alcohol is allowed as a preservative in cosmetics and personal care products at a maximum concentration of one percent. If it's used as a fragrance ingredient, the manufacturer is required to list it on the label when it's used at concentrations greater than 0.001 percent in leave-on products, and greater than 0.01 percent in rinse-off products.

Why would the EU care about labeling this ingredient? Because some studies have indicated that it can be a skin sensitizer, meaning that it can cause allergic reactions.

Increases Risks of Contact Allergies

Like many synthetic preservatives, benzyl alcohol can affect the immune system, gradually causing your skin to react. A 1998 study, for example, found that these reactions were possible, with researchers noting that the ingredient “can instigate immune system response that can include itching, burning, scaling, hives, and blistering of skin.”

The Material Data Safety Sheet (MSDS) on benzyl alcohol notes that it is a skin irritant, potentially causing redness and pain, as well as an eye irritant. Prolonged or repeated exposure can cause allergic contact dermatitis. It also warns that it may be toxic to the liver and central nervous system.

Another concern with benzyl alcohol is that like some other preservatives, it can break down to create aldehydes when combined with other chemicals, and one of those aldehydes can be formaldehyde, which is a known carcinogen. Again, the exposure levels are typically small, but still, this is something that you may not be entirely comfortable with.

The Environmental Working Group (EWG) classifies the ingredient as a “6,” or “moderate hazard,” so this isn't one of the horrible ones, but for those with sensitive or reactive skin, it's definitely one to avoid.

Dangerous for Young Children

The ingredient can be particularly dangerous for very young children. In 1982, the New York Times reported that the deaths of 16 low-weight, premature babies at two medical centers had been related to the benzyl alcohol used as a preservative in their IV fluids. The FDA urged hospitals and pediatricians to stop using the preservative, because two studies had linked the chemical to these deaths.

Benzyl alcohol had been used for years before that to flush out intravenous or arterial catheters after blood samples were drawn, so those same catheters could then be used in feeding or medicating a patient. It was also used as a simple preservative in some intravenous medications. But researchers found that the alcohol's toxic effects were enhanced in very small infants with tiny organs. Symptoms included respiratory failure, convulsions, hypotension, and paralysis.

It is now recommended that benzyl alcohol not be used for any infant products. Most do not carry it anymore, but be sure to check your ingredient lists on your baby products, including your lotions, soaps, shampoos, wipes, etc.

Safer, More Nourishing Choices

You can easily avoid this preservative by passing by any products that list it on the label. Be careful, as well, with products that simply say “fragrance” on the ingredient list, as that means the product could contain benzyl alcohol, but they don't have to tell you because fragrances are protected as proprietary formulas.

I prefer to use natural preservatives that aren't linked to such health problems, like Aspen bark and jasmine.

What do you think of benzyl alcohol? Have you had any negative experiences with it? Please share your story.

    Benzyl alcohol is no more wholesome if it comes from a natural source or whether it is made synthetically. There are many synthetic products that are added as preservatives at levels where they stimulate an allergic reaction of some sort and these should, of course, be avoided. However it is unwise to assume that it is because they are synthetic and therefore bad. There are many natural products that promote severe allergic reactions (nuts) leading to deaths in many cases however no-one is calling them to be banned.

      Why would they continue to use these in products that people are putting on there face. That’s very wrong, that people aren’t notified what they are putting on there face until they really look at the ingredients and pah attention for that kind of stuff.

    I used an over the counter product called Ivarest for a bad case of poison ivy on my neck, chin, face, arms and legs. I experienced an intense burning sensation on my skin for the four days I used it. It contains 10.5% benzyl alcohol and I didn’t know what that meant. Until now. My rash worsened and blistered. Now my neck and chin are deep purple and rough and scaly. The product is made by Blistex. I’m concerned about my skin being damaged from this. There were no warnings about allergic reactions. I thought the pain and burning were from the poison ivy. Thankfully I stopped using Ivarest and immediately started to feel better. I hope my skin will now be able to heal

      Lauren, I had a quarter sized patch of poison ivy come up on my forearm Tuesday morning. I applied Ivarest and by the end of the day, my left arm 3 inches below the patch to 4 inches above the patch wass a right red itchy welt. Ivarest is the only thing that was different from my every day routine so I’m thinking it has to be that!

    I’ve been using “Burt’s Bees Lip Balm,” (chapstick), as my lips are constantly chapped. (And yes, I need to drink more water.) I stopped using all other brands of chapstick, as they are petroleum-based. Burt’s Bees is beeswax-based. However, after reviewing product ingredients, one of the last 3 ingredients listed is Benzyl Alcohol.

    Are “Burt’s Bees Lip Balm(s)” perpetuating my chapped lip? If so, what other product can you recommend?

    • Annmarie Skin Care says

      Hey, Lorrie! The chapstick you are currently using could definitely be drying you out a bit if it contains any chemical ingredients. We would recommend our Antioxidant Lip Balm 🙂 It is very moisturizing and soothing! You can find that on our site for purchase. Enjoy!

    • Michelle Virissimo says

      Which “flavor” are you using? I don’t see benzyl alcohol listed at all? I am highly allergic to benzyl alcohol and Burts Bees regular (the one that just says peppermint and vit e) works great for me.

    I have stopped using commercial products on my lips. I have been using regular extra virgin olive oil and my lips no longer get dry. I apply it morning and night after washing my face and teeth. I no longer have to worry about ingesting harmful ingredients.
