Perfumed mixture of alcohol and essential oils (3,2,7)
I believe the answer is:
eau de cologne
'perfumed mixture of alcohol and essential oils' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for eau de cologne that I've seen before include "Mild perfume" , "Perfumed toilet water" , "EU-cleaned goo (anag)" , "Scent" , "Scented toilet water" .)
