What is lanolin?
Lanolin, also called Adeps Lanae, wool wax, wool fat, or wool grease, a greasy yellow substance from wool-bearing animals, acts as a skin ointment, water-proofing wax, and raw material (such as in shoe polish). Lanolin is “wool fat” or grease, chemically akin to wax, which is secreted by the sebaceous glands of wool-bearing animals, such as sheep. These glands are associated with hair follicles. Hope that helped.
Lanolin is a greasy, yellow substance that is produced by sheep to keep their wool dry and soft. Lanolin is soothing to the skin and naturally helps prevent bacteria from growing. It acts as a moisture barrier on skin and keeps wool in good condtion. Pharmaceutical grade lanolin has been purified to remove pesticides and other chemicals. When purified, lanolin is used as a base for ointments and creams, as a lubricant, and in finishing and preserving leather. It is also a constituent of some varnishes and paints. Lanolin is made of a mixture of cholesterol and the esters of several fatty acids. With water it forms an emulsion. As a waste product in wool processing, it is known also as wool wax, wool fat, or wool grease.
