    Lanolin

    Lanolin (from Latin lāna ‘wool’, and oleum ‘oil’), also called wool yolk, wool wax, or wool grease, is a wax secreted by the sebaceous glands of wool -bearing animals. Lanolin used by humans comes from domestic sheep breeds that are raised specifically for their wool. 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 primarily consists of sterol esters instead. Lanolin's waterproofing property aids sheep in shedding water from their coats. Certain breeds of sheep produce large amounts of lanolin.

  • Acetylated lanolin alcohol

    Acetylated lanolin alcohol (sometimes known as sheep alcohol, lanolin alcohol, or wool alcohol) is a non-drying organic compound produced from lanolin, the fat of wool shearings, which has been reacted with acetic acid and a small amount of lye. There are synthetic variants available; however, the animal-derived product has more anti-allergenic tendencies. Acetylated lanolin alcohol is used as an emollient, to soften skin, but is mildly comedogenic, with a rating of 0-2 out of 5. For this reason, those who are prone to whiteheads and blackheads should patch test before using on a large scale. Acetylated lanolin alcohol can also be inflammatory to those with wool or lanolin allergies, and should be avoided in such cases.
