Cholesteryl Chloride
What is Cholesteryl Chloride?
Cholesteryl Chloride is a synthetic derivative of cholesterol, a sterol lipid abundant in the skin's outer layer. Its chemical structure features a cholesterol backbone with a chloride group at the 3-position (C27H45Cl), enabling it to form organized cholesteric liquid crystal phases. Primarily used in decorative cosmetics like lipsticks and foundations, as well as some moisturizers, it acts as an emollient within the skin conditioning category. In formulations, it organizes into lamellar structures that parallel the skin's intercellular lipids, creating a breathable film that reduces transepidermal water loss while improving spreadability and texture. This alignment enhances the stability of emulsions and facilitates even application, offering a silky finish without greasiness. Its thermotropic properties also contribute to sensorial benefits in temperature-responsive products.
