EVS-EN ISO 22718:2015

This International Standard gives general guidelines for the detection and identification of the specified microorganism Staphylococcus aureus in cosmetic products. Microorganisms considered as specified in this International Standard might differ from country to country according to national
practices or regulations.
In order to ensure product quality and safety for consumers, it is advisable to perform an appropriate microbiological risk analysis to determine the types of cosmetic product to which this International Standard is applicable. Products considered to present a low microbiological (see ISO 29621) risk
include those with low water activity, hydro-alcoholic products, extreme pH values, etc.
The method described in this International Standard is based on the detection of Staphylococcus aureus
in a non-selective liquid medium (enrichment broth), followed by isolation on a selective agar medium.
Other methods may be appropriate dependent on the level of detection required.
