Lanolin

wool fat, an animal wax obtained by rinsing sheep’s wool; a viscous, brownish-yellow mass.

Lanolin differs from other waxes in its high sterol content (in particular, cholesterol). It is readily absorbed into the skin and has an emollient effect. Lanolin is widely used in the preparation of various cosmetics (for example, skin creams). In medicine it serves as a base for ointments and as a skin softener (in combination with an equal amount of petroleum jelly).
