lanolin

 [lan´o-lin]
wool fat or wool grease that is refined and incorporated into many commercial preparations. Lanolin is a by-product of the process that accompanies the removal of sheep's wool from the pelt. In its crude form it is a greasy yellow wax of unpleasant odor. This odor disappears when the lanolin is emulsified and made into salves, creams, ointments, and cosmetics. Although lanolin is slightly antiseptic, it has no other medicinal benefits and is valuable principally because of the ease with which it penetrates the skin, and because it does not turn rancid. Modified lanolin has been additionally processed to reduce the amount of free lanolin alcohols and detergent and pesticide residues.
