Minimum Inhibitory Concentration (MIC)
MIC testing determines the lowest concentration of a substance that inhibits visible growth of a microorganism after overnight incubation. We test against a panel of standard organisms including S. aureus, E. coli, P. aeruginosa, and C. albicans.
Minimum Bactericidal Concentration (MBC)
The MBC is the lowest concentration that kills ≥99.9% of the initial inoculum. MBC data is required for products making bactericidal claims and for natural preservative systems in cosmetics.
Preservative Efficacy (Antimicrobial Effectiveness Testing)
Per USP <51> and ISO 11930, we perform challenge testing to evaluate whether a cosmetic or pharmaceutical preservative system maintains product safety throughout its shelf life and during consumer use.
