Extracting Lanolin from Sheep's Wool, Edwardian Farm
In this clip from Edwardian Farm, Ruth Goodman extracts lanolin from sheep's wool.
Lanolin, also called wool wax or wool grease, is a yellow waxy substance secreted by the sebaceous glands of wool-bearing animals. Most lanolin used by humans comes fromdomestic sheep breeds that are raised specifically for their wool. Lanolin primarily consists of sterol esters. Its waterproofing property aids sheep in shedding water from their coats. Certain breeds of sheep produce large amounts of lanolin.
Lanolin and its many derivatives are used extensively in products designed for the protection, treatment and beautification of human skin.
Crude lanolin constitutes about 5-25% of the weight of freshly shorn wool. The wool from one Merino sheep will produce about 250-300 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 centrifugal separators, which concentrate it into a wax-like substance melting at approximately 38 °C (100 °F).

I was curious about how lanolin was extracted. I knew it had something to do with sheep, which made me concerned for the welfare of the animals. Now that I see it comes from their wool, which can be harvested without hurting the animals at all, I do not feel bad about using it in my products and may purchase some lanolin to try it out. Thank you for this educational video.
is the wool still able to be used for spinning?

boiling wool makes it into felt so you can make felt yarn from it

I know how you felt something after you've knitted it, but what is felt yarn?
I'm glad the sheep weren't harmed while getting the lanolin
no sheep were harmed in the process of getting the wool,right?

+Lillian Jenkins Correct., Sheep only need to be shaved/shorn to get the lanolin, it is NOT NECESSARY to kill the sheep to get the lanolin, in fact it's counter-productive since sheep produce wool/lanolin for the entirety of their lives.
