Lanolin USP

Applications

Lanolin is a natural wax derived from the sebaceous glands of sheep. This complex mixture consists of fatty acids, esters, alcohols, and hydrocarbons, renowned for its remarkable emollient and lubricating properties. This conditioning property is why the substance is now widely used in human cosmetics, skin care, and hair products. Notably, lanolin possesses the unique ability to absorb and retain substantial amounts of water, rendering it a valuable ingredient across a wide range of products. In vitro investigations utilize lanolin to focus on cell culture and enzyme activity.
