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 created in the mid-20th century from glycerin and stearic acid. Designed to replace traditional animal-derived emulsifiers with a more stable, consistent alternative for cosmetic manufacturing.
