Tri-C14-15 Alkyl Citrate

What is Tri-C14-15 Alkyl Citrate?

Tri-C14-15 Alkyl Citrate is an ester formed by reacting citric acid, an organic acid present in many fruits, with a blend of linear alcohols having 14 to 15 carbon atoms. This produces a lightweight, oily liquid commonly used in cosmetics for its emollient and plasticizing effects. In formulations, it lubricates the skin surface to minimize friction and enhance smoothness, while also aiding in the even distribution of other ingredients. As a plasticizer, it increases the pliability of polymer films in products like hair sprays and nail coatings, reducing stiffness and the risk of flaking. Its skin conditioning action supports overall skin feel by promoting suppleness. Typically incorporated into creams, lotions, serums, shampoos, and styling aids, it provides a silky, non-sticky finish without weighing down the skin or hair.
