Functions
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
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.
Emulsifier
Mixes Oil & Water
Traditional Use
A synthetic emulsifier developed in the mid-20th century from oleic acid (found in olive and other plant oils) combined with polyethylene glycol to create stable, water-soluble conditioning agents in modern skincare formulations.
