WoolWorks New Zealand Limited are the only supplier of New Zealand woolgrease

Wool grease is secreted from the sheep’s sebaceous glands which attaches to the wool fibres during the wool growing cycle.

This gives wool its waxy feel and protects the sheep from the natural elements and seasonal climatic changes.

After the greasy wool is removed during the shearing process, it is then subjected to washing and cleaning through the wool scouring process.

A state of the art three-stage recovery process continually removes wool grease from the wool as the wool is being washed. Recovered wool grease is then collected, cleaned and prepared for sale.

WoolWorks New Zealand is the world’s only supplier of pure New Zealand wool grease. This unique source of grease has many favourable attributes and is often a preferred choice due to it being consistently high in Cholesterol content.

The high cholesterol content of New Zealand wool grease is a pre requisite for those who choose wool grease to produce lanolin alcohol, cholesterol and Vitamin D3 as well as being popular for use in the manufacture of Lanolin and Lanolin Derivatives.

Lanolin is a semi-solid wax and contains a mixture of sterols and medium to long chain fatty acids. The properties of refined lanolin from wool grease function in many ways similar to human skin lipids, making it a very skin-compatible ingredient.

Lanolin has long been described as being a wonder of nature and has found use as a moisturizer, emollient, emulsifier and Ointment base for hundreds of years.
