Functions
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Locks In Moisture
Traditional Use
Developed in the mid-20th century as a synthetic polyglyceryl ester emulsifier. Created for use in cosmetic formulations requiring stable, consistent emulsification.
