Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Locks In Moisture
Traditional Use
A synthetic ester developed in the mid-20th century as a cosmetic emollient and thickening agent. Created to provide stable, long-lasting hydration in skincare formulations without the greasiness of natural oils.
