Cetyl Alcohol

Commonly feared, low concern·Strong evidence

A fatty alcohol used to soften skin and stabilize creams. Despite the name, it does not dry the skin.

The myth vs the evidence

The "no alcohol" crowd flags it because of the word alcohol. Fatty alcohols like cetyl and cetearyl are waxy emollients, the opposite of the drying, volatile alcohols (like alcohol denat) people mean.

Questions

Does cetyl alcohol dry out your skin?
No. Cetyl alcohol is a fatty alcohol, which means it is a waxy emollient that softens and conditions skin. It is the opposite of drying, volatile alcohols like denat alcohol or ethanol. The word alcohol in the name causes confusion, but cetyl, cetearyl, and stearyl alcohols are moisturizing ingredients.
Why does my no-alcohol product list cetyl alcohol?
When beauty labels say no alcohol, they mean no drying, volatile alcohols like ethanol or denat alcohol. Fatty alcohols like cetyl alcohol are emollients, not solvents, and do not dry the skin. They are chemically and functionally different from the alcohols people mean to avoid.
Is cetyl alcohol safe in skincare?
Yes. Cetyl alcohol is one of the most studied fatty alcohols and is graded safe for cosmetic use. It is used as an emollient and emulsifier in creams and lotions to soften and stabilize formulas. It is well tolerated and non-irritating at the concentrations used in cosmetics.
