Triisostearate
What is Triisostearate?
Triisostearate is a synthetic ester derived from isostearic acid, a branched-chain fatty acid produced by rearranging the structure of unsaturated fatty acids like oleic acid. It falls into the emollient and surfactant-emulsifying categories in cosmetics. This ingredient works by depositing a thin, occlusive layer on the skin to reduce moisture loss, imparting a smooth texture, and enhancing product spreadability. In formulations such as lotions, creams, and foundations, it bridges oil and water phases, preventing separation and improving consistency. Its branched molecular structure contributes to high stability, resistance to oxidation, and a non-greasy feel, making it ideal for leave-on products where long-lasting conditioning is desired.
Benefits
Softens and smooths skin surface for improved texture
