Microbiological testing:

Preservation failures are expensive, public and entirely preventable. We test preservative efficacy to the recognised standard, verify microbial quality, and — because we also design preservative systems — can tell you why a formulation failed rather than only that it did.

WHAT WE RUN

•  Preservative efficacy (challenge) testing to ISO 11930

•  Microbial content and specified-organism limit testing to ISO 21149 and ISO 18415

•  Water activity determination

•  Preservative-system validation across a product range

WHAT YOU RECEIVE

A report giving the challenge organism log reductions against the standard criteria, a clear pass or fail, and where relevant a recommendation on what to change.

WHO THIS IS FOR

Every manufacturer of a water-containing cosmetic product, at every reformulation and every new packaging format.
