A stability study measures the extent to which a product retains, within specified limits, and throughout its period of storage and use, the same properties and characteristics that it possessed at the time of compounding.
A study commonly includes: a stability indicating method assay, sterility (for sterile preparations), endotoxin (for most sterile preparations), pH, visual inspection, particulate matter, preservative effectiveness, preservative quantification, microbial limits (for non-sterile preparations), and the absence of specified organisms (for non-sterile preparations).
An antimicrobial effectiveness test demonstrates the effectiveness of antimicrobial preservatives in preventing microbial proliferation in injections, topicals, oral products, single dose vials, and antacids packaged in multiple-dose containers.
Microbial cleaning studies are essential to validating a facility’s cleaning SOP. Cosmetic manufacturers and suppliers must demonstrate that cleaning agents, combined with instructions and procedures for their use, remove microbial contamination from surface areas where cosmetic products are produced.
