Īn estimated 8,000 to 20,000 different types of lanolin esters are present in lanolin, resulting from combinations between the 200 or so different lanolin acids and the 100 or so different lanolin alcohols identified so far. Composition Ī typical high-purity grade of lanolin is composed predominantly of long chain waxy esters (approximately 97% by weight) the remainder being lanolin alcohols, lanolin acids and lanolin hydrocarbons. Lanolin and its derivatives are used in the protection, treatment and beautification of human skin. Lanolin's role in nature is to protect wool and skin from climate and the environment it also plays a role in skin (integumental) hygiene. Certain breeds of sheep produce large amounts of lanolin. ![]() Lanolin's waterproofing property aids sheep in shedding water from their coats. Lanolin primarily consists of sterol esters instead. Historically, many pharmacopoeias have referred to lanolin as wool fat ( adeps lanae) however, as lanolin lacks glycerides (glycerol esters), it is not a true fat. ![]() Lanolin used by humans comes from domestic sheepbreeds that are raised specifically for their wool. Lanolin (from Latin lāna ‘wool’, and oleum ‘oil’), also called wool wax or wool grease, is a wax secreted by the sebaceous glands of wool-bearing animals.
