Glyceryl Distearate
What is Glyceryl Distearate?
Glyceryl Distearate is a diester derived from glycerol and stearic acid, a long-chain saturated fatty acid often obtained from vegetable oils such as palm or soy. Chemically, it features two stearoyl groups attached to a central glycerin backbone, classifying it as a nonionic lipid. In cosmetic formulations, it primarily serves in the emulsifier and emollient categories, particularly in creams, lotions, and hair conditioners. It functions by stabilizing oil-in-water emulsions through its amphiphilic structure, preventing phase separation and creating smooth textures. As an emollient, it adheres to the skin or hair surface, filling irregularities to provide a silky feel and support the barrier against water loss. Its antistatic effect neutralizes electrical charges on hair shafts, reducing friction and enhancing detangling. This ingredient contributes to product spreadability and long-term stability without greasiness.
