33、)4 IntroductionMicrobiological examinations of cosmetic products are carried out according to an appropriate microbiological risk analysis in order to ensure their quality and safety for consumers.Microbiological risk analysis depends on several parameters such as the following: potential alteration
34、 of cosmetic products; pathogenicity of microorganisms; site of application of the cosmetic product (hair, skin, eyes, mucous membranes); type of users (adults, children under 3 years).For cosmetics and other topical products, the detection of skin pathogens such as Staphylococcus aureus, Pseudomona
35、s aeruginosa and Candida albicans may be relevant because they can cause skin or eye infections. The detection of other kinds of microorganism might be of interest since these microorganisms (including indicators of faecal contamination e.g. Escherichia coli) suggest hygienic failure during the manu
36、facturing process.DIN EN ISO 22718:2016-05 EN ISO 22718:2015 (E)5 1 ScopeThis 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 S
37、tandard 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 Stan
38、dard 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-select
39、ive liquid medium (enrichment broth), followed by isolation on a selective agar medium. Other methods may be appropriate dependent on the level of detection required.NOTE For the detection of Staphylococcus aureus, subcultures can be performed on non-selective culture media followed by suitable iden
40、tification steps (e.g. using identification kits).Because of the large variety of cosmetic products within this field of application, this method may not be appropriate for some products in every detail (e.g. certain water immiscible products). Other International Standards (ISO 18415) may be approp
41、riate. Other methods (e.g. automated) may be substituted for the tests presented here provided that their equivalence has been demonstrated or the method has been otherwise shown to be suitable.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this doc
