This International Standard gives general guidelines for the detection and identification of the specified
micro-organism Staphylococcus aureus in cosmetic products. Micro-organisms 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 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.
