A RAPID QUALITATIVE METHOD FOR MEASURING THE ION EXCHANGING ACTIVITY OF DERMATOLOGIC PREPARATIONS CONTAINING AN ION EXCHANGE RESIN

[摘要] A simple chemical method is descr. for measuring and comparing the ion exchanging activity of completed ointment, cream and lotion formulations containing a cationic exchange resin. The results indicate that, to be effective, prepns. of this type should be made with hydrophilic or water soluble vehicles.
