39、sumers, it is advisable to perform an appropriate microbiological risk analysis to determine the types of cosmetic products to which this document is applicable. Products considered to present a low microbiological risk (see ISO 29621) include those with low water activity or extreme pH values, hydr
40、o-alcoholic products, etc.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 methods (e.g. automated) can be substituted for the tests presented here prov
41、ided that their equivalence has been demonstrated or the method has been otherwise shown to be suitable.Yeast enumerated can be identified using suitable identification tests, for example, tests described in the standards listed in the Bibliography. Mould enumerated can be identified by other approp
42、riate methods, if necessary.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
