AGLAE conducts every year an interlaboratory comparison on cosmetic product: "challenge test".
During this accredited challenge test, laboratories perform preservation efficacy tests.

Two new tests are provided for the enumeration of aerobic mesophilic bacteria and yeasts/moulds and the detection of specified micro-organisms.

These tests provide laboratories with an assessment of their performance and guidelines for improvements if necessary.
