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
Created by esterifying polyglycerin with isostearic acid, a branched-chain fatty acid developed as a modern alternative to linear stearic acid. Designed to provide superior emulsification and skin-feel in cosmetics.
