Science
Mechanism of Action
As a primary emollient and skin conditioning agent, Diisostearyl Malate forms a thin, protective film on the skin's surface. This barrier actively reduces transepidermal water loss (TEWL), thereby significantly improving skin hydration. Its hydrophobic nature and specific C18 alkyl chain length facilitate its ability to penetrate the skin. Additionally, it exhibits surfactant properties and serves as an excellent dispersant and binder for pigments in color cosmetics, contributing to desired sheen and gloss.
