How is lanolin collected from sheep?

Lanolin is collected from sheep during the shearing process when their wool is harvested. As the wool is sheared, it is naturally coated with lanolin, a waxy substance produced by the sheep's skin glands to protect their wool and skin. After shearing, the wool is washed to remove dirt and impurities, during which the lanolin is extracted and collected from the washing water. The extracted lanolin is then refined for use in various cosmetic and industrial applications.
