WOOL FAT, ANHYDROUS LANOLIN
Refined wool fat, or lanolin, is one of the most common ingredients of cosmetics, soaps, and medicinal creams. It softens and soothes the skin and improves the skin penetration of other ingredients.
Many cosmetics, soaps, leather preparations, and medicines contain lanolin, the waxy coating that makes sheep's wool waterproof and warm. However, in spite of its usefulness, lanolin is one of the most common allergy-causing substances and therefore is usually labelled on skin preparations. Raw wool contains considerable quantities of crude lanolin, which is boiled off and refined.
