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 modern synthetic ester developed as an emollient and skin-conditioning agent in mid-to-late 20th century cosmetics. Created to provide smooth texture and enhanced stability compared to naturally occurring oils.
