Test on the Efficacy of Antimicrobial Preservation

The controlled quality and microbiological safety of a product are mandatory requirements for its safe use. The preservation system is an essential aspect of a product's microbiological safety and safety evaluation.

Labor LS has extensive expertise in testing the efficacy of antimicrobial preservation. We perform preservation challenge tests on the basis of the European, US and Japanese pharmacopoeias. We do not only examine according to the common regulatory requirements, but also develop and implement specific formulation methods.

  • Test on the efficacy of antimicrobial preservation according to DIN EN ISO 11930 (for cosmetic products) and DIN EN ISO 14730 (lens care products)
  • Suitability testing of the microbial count method
  • Development of new methods and implementation of special test procedures for already existing methods
  • Modified test design, depending on the application
