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
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.
