Lanolin is a yellow waxy substance secreted by the sebaceous glands of wool-bearing animals. Most lanolin used comes from domestic sheep breeds that are raised specifically for their wool.
Certain breeds of sheep produce large amounts of lanolin, and the extraction can be performed by squeezing the sheep's harvested wool between rollers. Most or all of the lanolin is removed from wool when it is processed into textiles.
Extracted from Wool by boiling and evaporation.
