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
Fights Bacteria
Locks In Moisture
Wound Healing
Mixes Oil & Water
Traditional Use
A modern synthetic derivative combining lanolin with polyethylene glycol, developed in the mid-20th century as a conditioning and emulsifying agent for cosmetics without independent traditional use.
