ISO 21150 Cosmetics - Microbiology - Escherichia Coli Search

The ISO 21150 standard, developed by the International Standards Organization (ISO), offers test methods for the detection of the microorganism escherichia coli in cosmetic products. Microorganisms in this standard may differ from country to country according to national practices or regulations.

In order to ensure product quality and safety for consumers, an appropriate microbiological risk analysis should first be performed to determine the types of cosmetic products to which this standard can be applied. Products with low microbiological risk, such as products with low water activity, hydro-alcoholic products and products with extreme pH values, are subject to the ISO 29621 standard.

The test method described in this standard is based on the detection of escherichia coli in a non-selective liquid medium followed by isolation on a selective agar medium. Other methods may be appropriate, depending on the level of detection required.

There is a wide variety of cosmetic products in this field of application and these test methods may not be suitable in every detail for some products. For example, some cosmetic products do not mix with water. If proven to be equivalent, other methods may be used instead of the test methods described in this standard.

The aforementioned standard was published by the Turkish Standards Institute (TSE) in our country with the title TS EN ISO 21150 Cosmetics - Microbiology - Escherichia coli search.

In the test, analysis, measurement and evaluation studies carried out in our organization, national and international standards and applicable legal regulations are complied with and reliable and impartial results are obtained. Among the numerous tests carried out in this context, there are services to search for escherichia coli in cosmetic products within the framework of the ISO 21150 standard.
