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
Synthetic ester developed in the 20th century as a volatile, lightweight emollient. Created to provide silky texture and quick absorption in cosmetic products without greasy residue.
