Valuable CAS 84931-78-2 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - EMULSIFYING, VISCOSITY CONTROLLING

Glyceryl Stearate Diacetate is a multifunctional ingredient primarily recognized for its skin conditioning properties. It deeply moisturizes by enhancing moisture retention and imparts a smooth, refined texture to the skin. Beyond its direct skin benefits, it significantly aids in stabilizing cosmetic formulations as an emulsifier.

Science

Mechanism of Action

This ingredient functions by creating a protective film on the skin's surface, acting as an emollient to reduce transepidermal water loss and a humectant to attract and bind moisture within the stratum corneum. This dual action supports optimal skin hydration and contributes to a smoother feel. In cosmetic formulations, it serves as an effective emulsifying agent, facilitating the stable blending of oil and water phases, and also helps regulate product viscosity.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Glyceryl Stearate Diacetate, classified as a glyceryl diester, is safe for use within current cosmetic practices and concentrations. The panel specifically noted that diglycerides, including diesters, do not pose significant acute toxicity risks and are neither irritating, sensitizing, nor photosensitizing. This safety profile is further supported by the FDA's approval of diglycerides as indirect food additives.
