Valuable / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Glyceryl Oleate/Elaidate is a multi-functional fatty acid ester prized for its ability to enhance skin smoothness and moisture retention by forming a protective lipid layer. It also plays a crucial role in formulation stability, acting as an emulsifier and thickener.

Science

Mechanism of Action

This ingredient functions as an emollient, establishing a protective barrier on the skin to boost smoothness and hydration, thereby softening and nourishing the epidermis. It effectively acts as a re-fatting agent, replenishing the skin's natural lipid content, which is particularly beneficial for dry or compromised skin. Furthermore, its amphiphilic structure enables it to stabilize oil and water phases in formulations, creating and maintaining emulsions, and it can also perform as a mild surfactant to assist in skin and hair cleansing by binding with fatty impurities.
