Functions
Light Stabilizer
Cleansing
Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Shields from UV damage
Traditional Use
Lanolin derives from wool grease and has been used as an emollient in skincare since ancient times. Hydrogenated laneth compounds were developed in the 20th century as modified lanolin derivatives designed to function as emulsifiers and conditioning agents with improved stability.
