Functions
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
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
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.
