What Cetearyl Alcohol does

Thickens creams, lotions and conditioners
Keeps oil and water blended
Softens skin and hair

Cetearyl alcohol is a fatty alcohol, a waxy material that is not the drying alcohol found in some toners. It is a blend of two longer-chain fatty alcohols, cetyl and stearyl. Manufacturers often make it from plant oils such as coconut or palm, though some use petroleum-based starting materials. It usually comes as white flakes or beads that melt into the mix.

Formulators use it mainly as a thickener and emulsion stabilizer. A stabilizer helps oil and water stay blended instead of separating. In a lotion, it adds body, so it feels richer and holds its shape. On skin and hair, it leaves a soft, smooth feel. You will find it in moisturizers, body lotions, sunscreens, shampoos and conditioners.

Good for

Suits most skin and hair types, especially people who want a creamy texture without a heavy, greasy film.

Frequently asked questions

Is cetearyl alcohol the same as drying alcohol?

No. Drying alcohols such as ethanol are short and light, and they can feel drying on skin. Cetearyl alcohol is a longer, waxy fatty alcohol. It thickens and softens, and it does not evaporate off the skin the way drying alcohols do.

Is cetearyl alcohol good for sensitive skin?

It is generally well tolerated and appears in many gentle creams. Any ingredient can bother some people, though. If you are sensitive, test a small amount on your inner arm first. Stop using it if you notice redness or itching.
