Lanolin (German, from Latin lāna, "wool", and oleum, "oil"), also called Adeps Lanae, wool wax or wool grease, is a yellow waxy substance secreted by the sebaceous glands of wool-bearing animals. Most lanolin used by humans comes from domestic sheep. Lanolin is also frequently, but incorrectly, referred to as ‘Wool Fat’ by many of the world’s pharmacopoeias even though it has been known for more than 150 years that lanolin is devoid of glycerides and is in fact a wax, not a fat. Lanolin's waterproofing property aids sheep in shedding water from their coats. Certain breeds of sheep produce large amounts of lanolin, and the extraction can be performed by squeezing the sheep's harvested wool between rollers. Most or all of the lanolin is removed from wool when it is processed into textiles, such as yarn or felt.
