Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Locks In Moisture
Traditional Use
Created in the mid-20th century as a synthetic humectant and emulsifier. Designed to replace natural plant-based emulsifiers while providing superior stability in formulations.
