Diglyceryl Sebacate/Isopalmitate

What is Diglyceryl Sebacate/Isopalmitate?

Diglyceryl Sebacate/Isopalmitate is a diester compound created by reacting sebacic acid, a dicarboxylic acid from castor oil sources, with isopalmitic acid, a branched-chain fatty acid, and diglycerol derived from glycerol. This synthetic ester serves primarily as an emollient and skin conditioning agent in cosmetic formulations such as creams, lotions, and serums. It functions by aligning with the skin's lipid structure to fill surface irregularities, promoting a smoother tactile feel and better product glide during application. The ingredient contributes to a lightweight, non-sticky sensory profile while helping to limit water evaporation from the skin's surface through mild film-forming properties. Its structure supports even distribution in emulsions, making it valuable in diverse product textures for everyday skincare routines.
