Functions

Emulsifying

Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.

Emollient

Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.

Skin Conditioning

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

Traditional Use

Developed in the mid-20th century as a synthetic emulsifier derived from glycerin and oleic acid. Created to replace natural emulsifiers and improve stability and texture in cosmetic formulations.
