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
Mixes Oil & Water
Traditional Use
Developed in the late 20th century as a synthetic emulsifier created by esterifying polyglycerin with myristic acid (a fatty acid derived from nutmeg or palm oil). Used in modern cosmetics as a gentler alternative to traditional synthetic emulsifiers.
