Cetyl alcohol

Cetyl Alcohol is a high–molecular weight fatty alcohol widely used in cosmetic, personal care, and pharmaceutical formulations. Despite the word “alcohol” in its name, cetyl alcohol is non-drying, non-irritating, and skin friendly. It is primarily used to improve the texture, stability, and sensory feel of products rather than acting as a solvent like ethanol.

Cetyl alcohol is typically derived from plant-based fatty acids such as palm or coconut oil, or produced synthetically. It is commonly supplied as white, waxy flakes or pellets and is a key structuring ingredient in creams, lotions, conditioners, and balms.
