Efficacy

Microbiological Challenge Studies

Preservative Efficacy Testing (CTFA) studies were run using different concentrations of the Geogard® LSA blend in various formulations to assess efficacy against various bacteria, yeast and fungi. All samples were inoculated at the beginning of the study, and then sampled at 24
hours, 7, 14, 21 and 28 days. Four weeks after challenge, samples were challenged again and the same sampling regime followed. Below is a summary of the results.
