forth by the European Pharmacopeia (EP). This implies that this sample has successfully undergone the required microbiological testing, and provided all other documentation aligns, it will be eligible for legal sale in the global market. As evidenced by the data presented in Tables 4 and 5, the outcomes are virtually identical, with the exception of a single result at two days for the Staphylococcus aureus test species. However, by the seven-day mark, the result reverts to <10, which is the desired outcome in any preservative efficacy test. In contrast, Sample B did not meet the
prescribed criteria and did not pass the European Pharmacopeia (EP) challenge test. Testing was ceased after collecting results from the 14-day evaluation. It is evident that Sample B experienced
failure at each testing interval: two, seven and 14 days, as indicated in both test methods (Tables 6 and 7). Results highlighted in red underscore the failure to achieve the required log reduction, signifying a failure at that particular testing point during the assessment period. The traditional testing approach, utilizing animal-derived media bases TSA and SDA, and the vegan-friendly alternative method, which employs media and materials free from animal- derived components, yield identical overall outcomes for both samples A and B. Our testing results have confirmed the
equivalence of the vegan alternative test method when compared to the traditional challenge test.
Conclusion Our findings demonstrate our ability to replicate the initial challenge test results through our in-house vegan alternative test method. Through our collaboration with The Vegan Society, we have obtained certification for the following test methods employed at ISCA Cosmetic Testing: European Pharmacopoeia (EP), United States Pharmacopeia (USP), ISO 11930, and our Total Viable Count (TVC) method. These accredited methods are available
to our clients and instil confidence in the knowledge that they are utilizing a micro- testing facility that not only efficiently tests their products but also does so in a vegan-friendly and certified manner since October 2022.
