Functions

Hair Conditioning

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

Emulsifying

Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.

Traditional Use

Created in the mid-20th century by chemically modifying lanolin (a traditional wool grease emollient used for centuries) with polyethylene glycol. Developed to improve lanolin's water-solubility and stability while retaining its moisturizing properties.
