Emollient

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.
