Cosmetics - Microbiology - Enumeration of yeast and mould
ISO 16212:2008 gives general guidelines for enumeration of yeast and mould present in cosmetics, by counting the colonies on selective agar medium after aerobic incubation.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 ISO 16212:2008 is applicable. Products considered to present a low microbiological risk include those with low water activity, hydro-alcoholic products, extreme pH values, etc.

Le présent document donne des lignes directrices générales pour le dénombrement des levures et des moisissures présentes dans les cosmétiques par comptage des colonies en milieu gélosé sélectif après une incubation aérobie. Le présent document décrit les principes, énumère les diluants, les agents neutralisants et milieux de culture, il détermine l'appareillage de verrerie, les souches de micro-organismes, la manipulation des produits cosmétiques et des échantillons, le mode opératoire, le comptage des colonies, les résultats, la neutralisation des propriétés fongistatiques, ainsi que le rapport d'essai.
ISO 16212:2017 gives general guidelines for enumeration of yeast and mould present in cosmetics by counting the colonies on selective agar medium after aerobic incubation. 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 products to which ISO 16212:2017 is applicable. Products considered to present a low microbiological risk (see ISO 29621) include those with low water activity or extreme pH values, hydro-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 provided 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 appropriate methods, if necessary.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
