What it is
Cetyl Esters is a defined mixture of esters made from long-chain fatty alcohols and fatty acids, giving a waxy solid with a pearly, creamy texture. It was developed as a synthetic substitute for spermaceti, the natural wax once obtained from whales. In sticks, balms, and creams it adds body, smooths texture, and imparts a soft, conditioned feel; in sunscreens it helps structure anhydrous and emulsion bases.
