For anyone curious about the ethical discussion folks are having
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 centrifuge separators, which concentrate it into a waxlike substance melting at approximately 38 °C (100 °F).

It seems like lanolin is typically extracted from the shorn wool, so I assume the comments about ethics are with respect to harvesting that wool in the first place, so if you're interested in learning more, that's where you'd want to research. I'm not intending to debate whether it is or isn't ethical (I know next to nothing about the wool industry), I just had no idea how lanolin might be obtained from a sheep, so I looked it up and figured I'd share since it's relevant to some of the conversation here
