VALIDATION OF NEUTRALIZATION METHODS—RECOVERY COMPARISONS A validated method for neutralizing the antimicrobial properties of a product should fulfill two criteria: neutralizer efficacy and neutralizer toxicity. The validation research documents that the neutralization method used is efficient in inhibiting the antimicrobial properties in the solution (neutralizer efficacy) without having impairing the Restoration of viable microorganisms (neutralizer toxicity). Validation protocols may perhaps fulfill both of these conditions by comparing recovery effects for remedy teams.
