ISO 21150 discusses Cosmetics. ISO 21150 gives general guidelines for the detection and identification of the specified microorganism Escherichia coli in cosmetic products.
Microorganisms considered as specified in ISO 21150 might differ from country to country according to national practices or regulations.
Note: Because of the large variety of cosmetic products within this field of application, this method might not be suited to some products in every detail (e.g., certain water-immiscible products). Other International Standards (ISO 18415) may be appropriate. Other methods (e.g., automated) can be substituted for the test presented here provided that their equivalence has been demonstrated or the method has been otherwise shown to be suitable.
ISO 21150 on Escherichia coli in cosmetic products is useful for:
To ensure product quality and safety for consumers, it is advisable to perform an appropriate microbiological risk analysis, to determine the types of cosmetic products to ISO 21150 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.
ISO 21150 provides you with a method that is based on the detection of Escherichia coli in a non-selective liquid medium (enrichment broth), followed by isolation on a selective agar medium. Other methods may be appropriate, depending on the level of detection required.
Microbiological examinations of cosmetic products are carried out according to an appropriate microbiological risk analysis to ensure their quality and safety for consumers. ISO 21150 helps you to detect microorganism Escherichia coli and to ensure and safety of your cosmetic products.
