Unbranded (7)
I believe the answer is:
generic
'unbranded' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for generic that I've seen before include "Non-specific" , "Applicable to any member of a class" , "(Of drugs) having no brand name" , "Not specific; of a class" , "Applicable to a whole class or group" .)
