Efficacy

Microbiological Challenge Studies
Geogard® 111 MICs versus widely used parabens

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.

Additional Information

Since Geogard® 111 preservatives are based on dehydroacetic acid with a pKa of 5.27, there is more activity across a wider pH range compared to other acids like sorbic acid at 4.76.

The efficacy of Geogard® 111 preservatives is pH dependent, offering greater efficacy at lower pH.
