Cosmetics - Microbiology - Detection of Pseudomonas aeruginosa (ISO 22717:2006)
ISO 22717:2006 gives general guidelines for the detection and identification of the specified micro-organism Pseudomonas aeruginosa in cosmetic products. Micro-organisms considered as specified in this ISO 22717:2006 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 ISO 22717:2006 is applicable. Products considered to present a low microbiological risk include those with low water activity, hydro-alcoholic products, extreme pH values, etc.
The method described in ISO 22717:2006 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.
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 (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 validated.
Kosmetik - Mikrobiologie - Nachweis von Pseudomonas aeruginosa (ISO 22717:2006)
Diese Internationale Norm gibt allgemeine Anleitungen für den Nachweis und die Identifizierung des vor-gegebenen Mikroorganismus Pseudomonas aeruginosa in kosmetischen Mitteln. Die in dieser Internationalen Norm vorgegebenen Mikroorganismen können in Übereinstimmung mit nationalen Praktiken oder Regelungen von Land zu Land unterschiedlich sein.
Um die Qualität des Produkts und die Sicherheit für Verbraucher sicherzustellen, ist es ratsam, eine geeignete mikrobiologische Risikoanalyse zur Bestimmung der Arten von kosmetischen Mitteln durchzuführen, für die diese Internationale Norm gültig ist. Produkte, die ein geringes mikrobiologisches Risiko darstellen, umfassen Produkte mit geringer Wasseraktivität, alkoholisch wässrige Produkte, Produkte mit extremen pH Werten usw.
Das in dieser Internationalen Norm beschriebene Verfahren basiert auf dem Nachweis von Pseudomonas aeruginosa in einem nicht selektiven Flüssigmedium (Anreicherungsbouillon), gefolgt von einer Isolation auf einem selektiven Agarmedium. In Abhängigkeit von der erforderlichen Nachweisgrenze können andere Verfahren angemessen sein.
ANMERKUNG Für den Nachweis von Pseudomonas aeruginosa kann eine Subkultivierung auf nicht selektiven Nährmedien erfolgen, gefolgt von geeigneten Schritten zur Identifizierung (z. B. unter Anwendung von Identifizierungskits).
Wegen der großen Vielfalt an kosmetischen Mitteln innerhalb dieses Anwendungsbereichs ist dieses Verfahren möglicherweise für einige Produkte nicht in allen Einzelheiten geeignet (z. B. bestimmte mit Wasser nicht mischbare Produkte). Andere Internationale Normen (ISO 18415 [10]) können zutreffen. Ersatzweise können für die hier aufgeführten Untersuchungen andere Verfahren (z. B. automatisierte) zur Anwendung kommen, vorausgesetzt, dass deren Gleichwertigkeit nach¬gewiesen oder das Verfahren anderweitig validiert wurde.
Cosmétiques - Microbiologie - Recherche de Pseudomonas aeruginosa (ISO 22717:2006)
L'ISO 22717:2007 donne des lignes directrices générales pour la recherche et l'identification du microorganisme spécifié Pseudomonas aeruginosa dans les produits cosmétiques. Les microorganismes considérés comme spécifiés dans la présente Norme internationale peuvent différer d'un pays à un autre, suivant les pratiques ou les réglementations nationales.
Pour garantir la qualité du produit et la sécurité des consommateurs, il est recommandé d'effectuer une analyse appropriée du risque microbiologique afin de déterminer les types de produit cosmétique qui relèvent de l'ISO 22717:2007. Les produits dont on considère qu'ils présentent un faible risque microbiologique comprennent ceux ayant une faible activité de l'eau, les produits hydroalcooliques, ceux ayant des valeurs de pH extrêmes, etc.
La méthode décrite dans l'ISO 22717:2007 repose sur la recherche de Pseudomonas aeruginosa dans un milieu liquide non sélectif (milieu liquide d'enrichissement), suivie de son isolement sur un milieu gélosé sélectif. D'autres méthodes peuvent être appropriées, en fonction du niveau de détection requis.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 22717:2006(E)
Introduction
Microbiological examinations of cosmetic products shall be 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:
⎯ potential alteration of cosmetic products;
⎯ pathogenicity of micro-organisms;
⎯ site of application of the cosmetic product (hair, skin, eyes, mucous membranes, etc.);
⎯ type of users (adults, children under 3 years).
For cosmetics and other topical products, the detection of skin pathogens such as Staphylococcus aureus,
Pseudomonas aeruginosa and Candida albicans may be relevant. The detection of other kinds of
micro-organism might be of interest since these micro-organisms (including indicators of faecal contamination
e.g. Escherichia coli) suggest hygienic failure during the manufacturing process.
INTERNATIONAL STANDARD ISO 22717:2006(E)
Cosmetics — Microbiology — Detection of Pseudomonas
aeruginosa
1 Scope
This International Standard gives general guidelines for the detection and identification of the specified
micro-organism Pseudomonas aeruginosa in cosmetic products. Micro-organisms 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 to determine the types of cosmetic product to which this International Standard is
applicable. Products considered to present a low microbiological 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 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 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 (e.g. certain water immiscible products). Other International
[10]
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 validated.
