Functions
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
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.
Emulsifier
Mixes Oil & Water
Traditional Use
Synthetic derivative combining PEG with lanolin, a natural emollient derived from sheep's wool that has been used in cosmetics since ancient times. The PEG modification was developed in the mid-20th century to improve water solubility.
