Mechanism of Action
As an emollient, Glyceryl Isostearate forms a protective barrier on the skin's surface, which helps to minimize trans-epidermal water loss. This action results in enhanced hydration, improved skin texture, and a smoother feel. Concurrently, it functions as a co-emulsifier, playing a vital role in stabilizing oil-and-water formulations by reducing interfacial tension. This contributes to the uniform dispersion of ingredients, improves product spreadability, and can promote desirable film formation on the skin. It also possesses properties beneficial for dispersing pigments in colored cosmetic applications.
