Which farm animal’s skin makes oil that is used in some creams and lotions?

Option A

Lanolin oil is a secretion from sheep’s skin. It’s similar to human sebum, an oil secreted by the sebaceous glands that you may notice particularly on your nose. Lanolin oil is extracted by putting sheep’s wool through a centrifuge machine that separates the oil from other chemicals and debris. The process is performed after the sheep is sheared so the extraction of lanolin causes no harm to sheep.

Raw wool contains 10 to 25 percent grease or "lanolin," which is recovered during the scouring process. Lanolin consists of a highly complex mixture of esters, alcohols, and fatty acids and is used in adhesive tape, printing inks, motor oils, and auto lubrication. Lanolin is also used in cosmetics and pharmaceuticals. Virtually all cosmetics and beauty aids, such as lipsticks, mascara, lotions, Creams, shampoos, and hair conditioners, contain lanolin.
