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.

Antioxidant Protection
UV Protection
Mixes Oil & Water
Traditional Use
Created by combining polyglycerin with stearic acid to form a robust emulsifier for cosmetics. Developed as a plant-based alternative to traditional wax-based emulsifiers in 20th-century skincare.
