Science
Mechanism of Action
This ingredient operates primarily as an emulsifier, binding immiscible oil and water phases to create stable, uniform cosmetic formulations. On the skin, it functions as a conditioning agent, imparting a silky, non-greasy feel and improving product spreadability. Its emollient and moisturizing properties help to soften the skin, reinforce the natural moisture barrier, and form a protective film that minimizes transepidermal water loss. Additionally, its humectant nature attracts and retains moisture on the skin's surface, promoting increased hydration and improved elasticity. As a mild surfactant, it reduces surface tension, aiding in the gentle removal of impurities.
