some knowledge about Lanolin

Lanolin is a sheep of the sebaceous gland secretion, deposited in the wool oil secretion, to maintain and protect the physical properties of wool. In the early period of ancient Greece, people have been aware of the usefulness of lanolin, but due to its complex composition, refining difficulties, and are a by-product of the wool industry, therefore have not been given enough attention. China's wool production ranks second in the world, with an annual output of 250000 tons of raw hairs, wool fat content of 9%-12%, about 25000 tons. At... [Lire la suite]
