C10-16 Alcohols

What is C10-16 Alcohols?

C10-16 Alcohols consist of a blend of straight-chain primary fatty alcohols with carbon chain lengths ranging from 10 to 16 atoms, including decyl, lauryl, myristyl, and cetyl alcohol. Derived primarily from vegetable oils such as coconut or palm kernel through reduction processes, they appear as white, waxy solids. In cosmetics, they serve in the emollient and skin conditioning category, commonly found in moisturizers, lotions, and hair care. They function by melting into the skin upon application, creating a protective layer that fills in surface imperfections for a smoother texture, enhances slip for easy application, and supports barrier function to limit water evaporation. Their thickening properties also stabilize emulsions, providing a non-greasy, velvety finish.
