Microbiological Stability – Preservative Efficacy Testing – ISO 11930

Microbiological stability is essential for the safety of cosmetics, and evidence of this is part of the safety report for cosmetics according to Regulation (EC) No. 1223/2009. 

The test is generally carried out according to ISO 11930 and includes 5 test microorganisms (Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, Candida albicans, Aspergillus brasiliensis). Additional microorganisms such as Pluralibacter gergoviae or Burkholderia cepacia can be included. Occasionally it is also recommended to include isolates from the production environment in the spectrum.
