Minimum Inhibitory Concentrations (MIC) for Geogard® 111A Compared to Parabens

Studies were run using different concentrations of Geogard® 111 in an anionic shampoo to see efficacy against various bacteria, yeast and fungi. All samples were inoculated at the beginning of the study, sampled at 24 hours, 3, 7, 14 and 28 days.
