What Is C12-16 Alcohols?
C12-16 Alcohols is a mixture of fatty alcohols with 12 to 16 carbons in the alkyl chain. Like other fatty alcohols (such as Cetyl, Stearyl, and Cetearyl Alcohol), it functions as an emollient, helping to soften and smooth the skin. It is also used as a thickening agent and emulsion stabilizer in cosmetic formulations, preventing the oil and water phases from separating. These types of fatty alcohols are non-irritating and non-drying, and are considered beneficial for the skin.
