WOOL GREASE - DATA SHEET

Wool grease is a natural product secreted by the sebaceous glands in the sheep skin making it a naturally occurring and renewable resource. Recovery occurs during the process of aqueous scouring of greasy wool utilizing ethoxylated detergent.  Recovered Wool grease is routinely referred to by numerous descriptions; neutral wool grease, centrifuged wool grease, wool grease crude, wool wax, lanolin industrial being a few common descriptions.

Component analysis of purified Wool Grease naturally varies reflective of breed of sheep, country of origin and can be influenced by processes utilized during recovery.  Purified Wool Grease ex scour typically contains;

     
1 % moisture   ●   95 - 97% wool wax esters   ●    2 – 4% wool wax alcohol    ●    Ash <  less than 0.25%

Quality.

Melting Point:   38-42 degrees Celsius

Acid Value: 2 - 8 maximum mgKOH/gm

Mineral Content:  Analysis on request
Cholesterol Content: 9 -13%, typically varies by country

   of origin, sheep breed and local climatic conditions
 

Melting Point and Acid Value are determined according to the British Pharmacopeial tests prescribed for wool fat (anhydrous lanolin).  Moisture Content is determined by the loss on drying test (1hour test at 105 degrees Celsius), Ash Content by the Sulphated Ash Test without using Sulphuric Acid. Mineral and Cholesterol content determined on request to Internationally published methods.
