Small soft bag of powder (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
sachet
(Other definitions for sachet that I've seen before include "Package" , "'Small soft bag, for perfumed powder say (6)'" , "Cheats (anag) -- small porous bag" , "Small bag - chaste (anag)" , "Sealed bag or packet" .)
