Functions

Skin Conditioning

A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.

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 an emollient and solvent for cosmetic formulations. No traditional use; created to provide a light feel and improve absorption in skincare products.
