Cetylpalmitat

Cetyl palmitate is a waxy ester that occurs as a solid at room temperature. It is the ester of cetyl alcohol and palmitic acid, giving it the chemical formula C32H64O2. In cosmetics and personal care products, it is used primarily as an emollient and thickener, helping to create a smooth, glide-on feel and to improve texture.

Production typically involves esterification of cetyl alcohol (a 16-carbon primary alcohol) with palmitic acid (a 16-carbon saturated fatty acid). The resulting cetyl palmitate is a long-chain fatty ester that is stable under normal cosmetic processing conditions. It is commonly used in many oil- and water-containing formulations.

Applications: In creams, lotions, lip balms, foundations, and hair care products, cetyl palmitate acts as an emollient, forming a soft film on the skin that reduces water loss and enhances slip. It also contributes thickness and rheological properties, improving product spread and texture.

Safety and regulation: Cetyl palmitate is widely used in cosmetic formulations and is generally considered safe when used as directed. It is typically non-irritating and non-sensitizing for most users. It is listed under the INCI name Cetyl Palmitate and is subject to cosmetic ingredient regulations in jurisdictions where cosmetics are sold.
