Science

This ingredient operates on multiple levels: as an emulsifier, it effectively combines immiscible oil and water phases, forming stable emulsions with a refined texture. Its emollient properties allow it to soften and smooth the skin by filling microscopic intercellular gaps, imparting a silky tactile experience. It functions as a skin conditioning agent, optimizing product feel and enhancing spreadability across the skin surface. By strengthening the skin’s natural barrier function, it minimizes transepidermal water loss, thereby reducing dryness and bolstering protection against environmental stressors. It also contributes to hydration by attracting and retaining moisture, supporting skin elasticity. As a mild surfactant, it reduces surface tension, facilitating ingredient dispersion and aiding in the removal of impurities. Furthermore, it acts as a texture enhancer, providing a non-greasy, lightweight feel and ensuring excellent dispersibility for inorganic pigments and powders.
