What is cosmetic PET testing?
PET means preservative efficacy testing, also called challenge testing. It evaluates how effectively a product's preservation system controls microbial contamination under the chosen test conditions. Cosmetic PET testing is different from stability testing: preservation performance and physical or chemical stability answer different questions. Nanuvo lists PET in its manufacturing project documentation. Ask us to define the appropriate protocol, testing scope and documentation for your formula; testing does not guarantee regulatory approval.
