Cavalier Woolscourers Limited are the only supplier of New Zealand woolgrease. As part of our world class wool scouring process, woolgrease is washed from the wool and recovered as a valuable by product.
Wool Grease (Wool wax or Crude Lanolin) is a natural substance expressed from the sebaceous gland of the sheep, designed by nature to soften both skin and wool fibres, and to protect them against adverse weather conditions. It is a by-product of the Scouring process in which a hot water and detergent solution is used to remove all the wool grease substances from the wool.
The wool grease is then recovered from the scouring liquids by high-speed centrifugation. Depending on the breed of sheep, the season and the quality of the wool, crude wool grease makes up about 2% of the weight of the shorn fleece.
Humans have valued its well-tolerated beneficial qualities for thousands of years. Nowadays this unique, created by nature substance is widely used in many products and various technical applications:
Cavalier Woolscourers woolgrease is sold to all of the major refining companies around the world as a raw ingredient for a diverse range of pharmaceutical and feedstock products, including lanolin for cosmetics and cholesterol for animal feed supplements. Woolgrease is also a rich source of vitamin D3 which is growing in demand in dietary supplements.
Lanolin is a key ingredient in some of the world’s most popular cosmetics and pharmaceuticals. Without it, they would not have the emollient qualities that protect and care for our skin and hair.
