Mechanism of Action
This ester derivative primarily acts as a skin conditioning agent, delivering emollients that soften and smooth the skin's surface. Concurrently, it operates as a surfactant and emulsifying agent, which is crucial for forming and maintaining stable oil-in-water and water-in-oil cosmetic emulsions. This dual action contributes to superior formulation stability, provides a rich and elegant skin feel, and significantly improves the product's spreadability. It can also serve as a natural alternative to silicones in certain formulations and offers synergistic stabilization when paired with inorganic sunscreen filters.
