Antimicrobial Effectiveness Testing
Antimicrobial Effectiveness Testing, also known as the Preservative Efficacy Test or Microbial Challenge Study, is performed to determine if the chosen preservative is appropriate for a product formulation. It is also carried out as part of a stability study to ascertain whether a preservative system is still effective up to the expiration date of a product. Testing is performed according to compendial requirements in both USP <51> and EP 5.1.3. More information.
