Description
A fatty, pale yellow solid that coats the fibers of a sheep's wool. Raw wool contains about 20% grease and 12% suint. Wool grease, or wax, is separated from the suint, or salts, by a solvent cleaning procedure. The wax contains a mixture of esters and alcohols, including cholesterol and isocholesterol. It emulsifies with water and can take up to about 80% of its weight in water. Wool wax is used for ointments, emollients, soaps, and dressing leather and furs. Purified wool wax is called lanolin.
