Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Locks In Moisture
Traditional Use
Synthetic hybrid emulsifier combining PEG technology with natural glycerin, developed in the latter half of the 20th century. Created to combine the stability of synthetic emulsifiers with perceived naturalness of glycerin-based systems.
