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
A synthetic emulsifier developed in the late 20th century by esterifying polyglycerin with decanoic acid (a medium-chain fatty acid). Created for cosmetic formulations requiring mild, non-irritating emulsification.
