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.
Emulsifier
Antioxidant Protection
UV Protection
Mixes Oil & Water
Traditional Use
A modern emulsifier combining polyglycerin with oleic acid in a higher ratio for improved emulsifying power. Developed to create more stable and elegant cosmetic formulations in contemporary products.
