I am looking for any creative ideas on a suitable exfoliant to use other than Aluminium Oxide.
Have been using Aluminium oxide in a product for many years, changed to a different contract manufacturer and the crystals managed to damage the tube filler (scratching internally, I assume based on the hardness).
My client would still like to claim that the product has micro crystals. I was thinking of using Magnesium Oxide however it doesnt seem to be possible to import it into Australia even though it is listed.
Any other ideas of exfoliants which are or can be called micro crystals?
