Isopropyl Linoleate

What is Isopropyl Linoleate?

Isopropyl linoleate is an ester derived from linoleic acid, an essential omega-6 fatty acid sourced from vegetable oils such as safflower or sunflower, and isopropyl alcohol. In cosmetic formulations, it functions mainly as an emollient and skin conditioning agent. It integrates into the skin's lipid matrix, promoting suppleness by filling in rough patches and aiding moisture retention through barrier support. Its low viscosity provides a smooth, non-greasy feel, improving spreadability in lotions, creams, and makeup. As a binder, it strengthens the cohesion of solid products like lipsticks, pressed powders, and sticks, enhancing durability and application ease. This ingredient mimics natural sebum components, contributing to a balanced, conditioned skin surface in various personal care items.
