In conditions exactly where There exists inadequate dampness, for instance for most solid dosages and ointments, water activity (Aw) is the more favored measurement to make certain Charge of progress on security considering that Aw is often a attribute with the system compared with the microbial inhabitants. Use of the here measurement for microbial security is explained in USP Application of Water Activity Measurement in Non-sterile Pharmaceutical Products. In the course of growth it is useful to reveal a reliable dosage for many weeks outside its bundle to large temperature and humidity to create a water exercise profile.
