Editing Lanolin (section)

== Production ==

Crude lanolin constitutes about 5–25% of the weight of freshly shorn wool. The wool from one [[Merino sheep]] will produce about 250–300&nbsp;ml of recoverable wool grease. Lanolin is extracted by washing the wool in hot water with a special wool scouring detergent to remove dirt, wool grease (crude lanolin), [[suint]] (sweat salts), and anything else stuck to the wool. The wool grease is continuously removed during this washing process by [[Centrifugation|centrifuge]] separators, which concentrate it into a waxlike substance melting at approximately {{convert|38|°C}}.<ref>{{Cite journal|last1=Sengupta|first1=Amit|last2=Behera|date=2014|title=Comprehensive view on chemistry, manufacturing & applications of lanolin extracted from wool pretreatment,also used in vitamins|url=http://ajer.org/papers/v3(7)/F0373343.pdf|journal=American Journal of Engineering Research|volume=3|issue=7|pages=33–43|access-date=13 November 2018|archive-date=13 July 2019|archive-url=https://web.archive.org/web/20190713075638/http://ajer.org/papers/v3(7)/F0373343.pdf|url-status=live}}</ref>
