Vegan Cosmetic Challenge Testing - PET Testing

Isca Cosmetic Testing have partnered with The Vegan Society™ to certify several microbiological test methods. Existing micro test protocols require the use of culture media and auxiliaries that contain animal by-products. Our new methods replace these substances with vegan alternatives, which have been validated to ensure equal performance. Isca’s vegan certified methods include Preservative Efficacy Tests (PET), such as EP / USP challenge tests, and Total Viable Counts.
