Valuable CAS 1323-83-7 / ANTISTATIC, SKIN CONDITIONING - EMOLLIENT

Summary

Emollient Emulsifying Viscosity controlling

Science

Mechanism of Action

This ingredient functions on the skin's surface by forming a protective, lubricating barrier. This barrier helps to mitigate moisture loss, ensuring sustained hydration without creating a greasy or pore-clogging sensation. Within formulations, Glyceryl Distearate acts as an effective emulsifier, stabilizer, and thickener, ensuring that oil and water components blend uniformly into a stable emulsion. This dual action not only improves product spreadability but can also facilitate the absorption of other active ingredients, contributing to a soft and velvety skin finish.
