Cetearyl alcohol is a mixture of fatty alcohols, primarily cetyl alcohol and stearyl alcohol, derived from natural sources such as coconut oil or palm oil. It consists mainly of long-chain saturated fatty alcohols, with carbon chain lengths ranging from C16 to C18. It's uses are:
1. Emulsifying Agent: Cetearyl alcohol also serves as an emulsifying agent in cosmetic formulations, facilitating the mixing of oil and water phases to create stable emulsions.
2. Thickening Agent: Due to its waxy nature, cetearyl alcohol contributes to the viscosity and texture of cosmetic formulations.
3. Hair Care: In addition to its skincare benefits, cetearyl alcohol is used in hair care products such as conditioners, hair masks, and styling products.
4. Stabilizer: Cetearyl alcohol can stabilize emulsions and prevent them from breaking down over time.
