What Is Cetyl Alcohol?

Cetyl Alcohol is a long-chain fatty alcohol derived from coconut or palm oil. Despite having 'alcohol' in its name, it is not a drying alcohol and actually serves as a conditioning and emollient ingredient. It is a waxy white solid that gives conditioners and styling products their creamy, rich texture.

Source: Coconut oil or palm oil

Origin: Natural

Also known as: Palmityl Alcohol, 1-Hexadecanol, Cetanol

What Does Cetyl Alcohol Do to Your Hair?

Cetyl Alcohol acts as an emollient and emulsifier, softening the hair and helping oil and water ingredients blend together in formulations. It coats the hair shaft to smooth the cuticle, reduce friction, and add slip for easier detangling. It also thickens product formulations and provides a luxurious feel.
