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 modern polyethylene glycol derivative of lanolin, itself used for centuries as a wool grease lubricant and traditional emollient. Developed in the 20th century to make lanolin more water-soluble and suitable for light cosmetic applications.
