33、17:2006), of which it constitutes a minor revision.DIN EN ISO 22717:2016-05EN ISO 22717:2015 (E)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.Microbio

34、logical risk analysis depends on several parameters such as the following: potential alteration 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 ot

35、her topical products, the detection of skin pathogens such as Staphylococcus aureus, Pseudomonas 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 ind

36、icators of faecal contamination e.g. Escherichia coli) suggest hygienic failure during the manufacturing process.DIN EN ISO 22717:2016-05EN ISO 22717:2015 (E)5 1 ScopeThis International Standard gives general guidelines for the detection and identification of the specified microorganism Pseudomonas

37、aeruginosa 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 microbiolo

38、gical risk analysis to determine the types of cosmetic product 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, etc.The method described in

39、 this International Standard is based on the detection of Pseudomonas aeruginosa 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.NOTE For the detection of Pseudomonas

40、 aeruginosa, subcultures can be performed on non-selective culture media followed by suitable identification 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 in every detail for some products

41、 (e.g. certain water immiscible products). Other International Standards (ISO 18415) may be appropriate. 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 Normat

48、lated from a wide variety of environmental sources, especially in water and has a very high potential to spoil many different substrates. It may produce infections of human skin or eye area. It is undesirable in cosmetic products for its potential pathogenicity and its capacity to affect the physico-chemical properties of the cosmetic formula.3.7enrichment brothnon-selective liquid medium containing suitable neutralizers and/or dispersing agen
