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.
Viscosity Controlling
Locks In Moisture
Traditional Use
Developed in the mid-20th century as a synthetic fatty alcohol derived from shark liver oil or plant sources. Used in cosmetics as an emollient and thickening agent to replace natural whale-derived ingredients.
