Sweet, own scent (10)
I believe the answer is:
aftershave
'scent' is the definition.
'sweet own' is the wordplay.
'sweet' becomes 'afters' (I've seen this before).
'own' becomes 'have' ('have' can be a synonym of 'own').
'afters'+'have'='AFTERSHAVE'
(Other definitions for aftershave that I've seen before include "alcohol to splash on, say" , "Dad's expected present?" , "Fragrance" , "Soothing spirit" , "cheeky alcoholic preparation" .)
