Neat woman’s brief description of a certain acid? (6)

I believe the answer is:

oxalic

'description of a certain acid?' is the definition.
(as in oxalic acid)

'neat woman's brief' is the wordplay.
'neat' becomes 'ox' (neat historically meant a cow or ox).
'woman's brief' becomes 'alic' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ox'+'alic'='OXALIC'

I've seen this clue in The Times.
