All in on exploitation of ointment ingredient (7)
I believe the answer is:
lanolin
'ointment ingredient' is the definition.
(I've seen this in another clue)
'all in on exploitation' is the wordplay.
'all in on' can be anagrammed to 'LANOLIN'.
Though, I am unsure how this is indicated.
'of' is the link.
Can you help me to learn more?
(Other definitions for lanolin that I've seen before include "Secretion on wool" , "Ointment containing wool fat" , "Fat extracted from wool" , "Oil on sheep's wool" , "Fatty substance on wool" .)
