Overview
This International Standard gives general guidelines for the detection and identification of the specified microorganism Escherichia coli 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, so as to determine the types of cosmetic products 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, etcetera. The method described in this International Standard 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. This document (EN ISO 21150:2015) has been prepared by Technical Committee ISO/TC 217 "Cosmetics" (secretariat: ISIRI, Iran) in collaboration with Technical Committee CEN/TC 392 "Cosmetics", the secretariat of which is held by AFNOR (France). The responsible German standardization committee is Working Committee NA 057-07-01 AA "Kosmetische Mittel" ("Cosmetics") at DIN Standards Committee Food and Agricultural Products (NAL).
