LANOLIN is an oily, yellowish substance extracted from wool-bearing animals like sheep used for a variety of products ranging from skin ointments, water-proofing wax and other raw materials found in items like shoe polish.
Also called wool wax, wool fat or wool grease, this substance is produced by sheep and other wool-bearing animals through their sebaceous glands which are associated with hair follicles.
Frequently used as raw material for producing vitamin D3, the name lanolin originated from a trademark later known as the generic term for a preparation of sheep fat and water.
Recent studies showed that antibiotics are present in the lanolin. As a water-proofing agent lanolin helps sheep shed water from their coats.
According to studies some breeds of sheep produce large amounts of lanolin. Lanolin is extracted by squeezing the wool between rollers.
Manufacturers remove most if not all the lanolin when the wool is processed into textiles like yarn or felt.
Lanolin is mostly a mixture of cholesterol and the esters of several fatty acids. Crude or non-medical grades of lanolin also contain wool alcohols that may cause allergies for some people.
Insoluble in water, lanolin is considered an excellent emollient and as mentioned, is used in many commercial products varying from rust-preventative coatings to cosmetics to lubricants.
Sailors are known to use lanolin to create a slippery surface on their propellers and stern gear that prevents creatures like sea barnacles from sticking on.
