Lanolin is a natural moisturizer with powerful emollient and protective properties. The composition of lanolin resembles the intercellular lipids of the stratum corneum. This is the outermost layer of the skin, which consists of cholesterol, cholesterol derivatives, and free fatty acids. These lipids play a crucial role in the skin’s moisture control. Under normal conditions, water continuously evaporates from the skin's surface. Lanolin is an ideal and widely used ingredient for toiletries, personal-care products, and medical applications.
