Cetyl Lactate
What is Cetyl Lactate?
Cetyl Lactate is an ester created by reacting cetyl alcohol—a long-chain fatty alcohol sourced from plant oils such as coconut or palm—with lactic acid, obtained via fermentation processes from carbohydrates. In skincare formulations, it serves primarily as an emollient and skin conditioning agent within moisturizers, lotions, creams, and decorative cosmetics. It functions by depositing a thin, lightweight layer on the skin that mimics natural lipids, thereby filling in minor surface imperfections for a smoother feel, enhancing product glide during application, and supporting the skin's barrier to limit water evaporation. This provides a non-oily, velvety finish preferred in both lightweight serums and richer emulsions, contributing to overall product stability and sensory appeal without heaviness.
