Description
A semisolid waxy material that is purified from the grease, or Degras, extracted from Wool. Lanolin is a complex mixture of 33 high molecular weight alcohols and 36 fatty acids, including Cholesterol. It also contains about 5% free alcohols and free acids. One of the unique properties of lanolin is that it can incorporate up to 25-30% water without separation. Since it is readily absorbed by skin, lanolin is used as an emollient in Leather dressings as well as for cosmetics and ointments. It is also used as a rust preventative.
Synonyms and Related Terms
lanoline; animal wax; wool wax; wool grease; wool fat; lanoline; Lanain; Lanum; adeps lanae; oesipos; Agnolin; Lantrol; Loanilin (Deut., Sven.); Lanolina (Pol);
Risks
Contact will cause of reaction in persons with wool allergies.
