Solvent, take note, capitalist is bearing up! (7)
I believe the answer is:
acetone
'solvent' is the definition.
(acetone is a kind of solvent)
'take note capitalist is bearing up' is the wordplay.
'is bearing' indicates the answer is hidden within the clue (the clue carries or bears the answer inside it).
'up' says the letters should be written in reverse (in down clue: letters go upwards).
'enoteca' is hidden in the letters of 'take note capitalist'.
'enoteca' in reverse letter order is 'ACETONE'.
(Other definitions for acetone that I've seen before include "Colourless solvent" , "Remover of nail polish" , "Eat once (anag) - solvent" , "it dissolves" , "chemical is the solution" .)
