The validation analyze documents that the neutralization method employed is helpful in inhibiting the antimicrobial Qualities in the product or service (neutralizer efficacy) devoid of impairing the recovery of viable microorganisms (neutralizer toxicity). Validation protocols may possibly satisfy both of these requirements by comparing recovery success for treatment method groups.
The RE is calculated by comparing the total amount of colonies recovered (from all of the rinses) to the initial rinse. This method is unsuitable for powders, gels, or some other dissolving substance.
