Functions

Antioxidant

Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.

Plasticiser

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

Developed in the mid-20th century as a synthetic ester emollient designed to replace natural plant oils. Used in cosmetics since the 1950s as a lightweight conditioning agent and skin softener.
