Cosmetics - Microbiology - Detection of Staphylococcus aureus (ISO 22718:2015)
ISO 22718:2015 gives general guidelines for the detection and identification of the specified microorganism Staphylococcus aureus 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 microbiological 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 this International Standard is based on the detection of Staphylococcus aureus in a non-selective 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 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 for some products in every detail (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.
Kosmetische Mittel - Mikrobiologie - Nachweis von Staphylococcus aureus (ISO 22718:2015)
Diese Internationale Norm gibt allgemeine Anleitungen für den Nachweis und die Identifizierung des festgelegten Mikroorganismus Staphylococcus aureus in kosmetischen Mitteln. Die in dieser Internationalen Norm festgelegten 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 anwendbar ist. Produkte, die ein geringes mikrobiologisches Risiko (siehe ISO 29621) darstellen, umfassen jene mit geringer Wasseraktivität, alkoholisch wässrige Produkte, Produkte mit extremen pH Werten usw.
Das in dieser Internationalen Norm beschriebene Verfahren basiert auf dem Nachweis von Staphylococcus aureus 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 Staphylococcus aureus kann eine Subkultivierung auf nicht selektiven Nähr-medien 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) können geeignet sein. Ersatzweise können für die hier aufgeführten Untersuchungen andere Verfahren (z. B. automatisierte) zur Anwendung kommen, vorausgesetzt, dass deren Gleichwertigkeit nach¬gewiesen oder sich das Verfahren anderweitig als geeignet erwiesen hat.
Cosmétiques - Microbiologie - Détection de Staphylococcus aureus (ISO 22718:2015)
ISO 22718:2015 donne des lignes directrices générales pour la détection et l'identification du microorganisme spécifié Staphylococcus aureus dans les produits cosmétiques. Les microorganismes considérés comme spécifiés dans la présente Norme internationale peuvent différer d'un pays à l'autre suivant les pratiques ou les réglementations nationales.
Pour garantir la qualité du produit et la sécurité des consommateurs, il est préférable d'effectuer une analyse appropriée du risque microbiologique afin de déterminer les types de produits cosmétiques qui relèvent de la présente Norme internationale. Les produits considérés comme présentant un faible risque microbiologique (voir ISO 29621) comprennent ceux ayant une faible activité de l'eau, les produits hydroalcooliques, ceux ayant des valeurs de pH extrêmes, etc.
La méthode décrite dans la présente Norme internationale repose d'abord sur la détection de Staphylococcus aureus dans un milieu liquide non sélectif (bouillon d'enrichissement), suivie d'un isolement sur un milieu gélosé sélectif. D'autres méthodes peuvent être appropriées en fonction du niveau de détection exigé.
NOTE Pour la détection de Staphylococcus aureus, il est possible de réaliser des subcultures sur des milieux de culture non sélectifs, puis de procéder aux étapes appropriées d'identification (par exemple en utilisant des kits d'identification).
En raison de la grande variété de produits cosmétiques relevant de ce domaine d'application, il se peut que cette méthode ne soit pas adaptée en tous points à certains produits (par exemple aux produits non miscibles à l'eau). D'autres Normes internationales (ISO 18415) peuvent être appropriées. Il est possible de remplacer les essais présentés ici par d'autres méthodes (par exemple des méthodes automatisées) sous réserve que leur équivalence ait été démontrée ou que la méthode ait été par ailleurs indiquée comme adéquate.
Kozmetika - Mikrobiologija - Ugotavljanje prisotnosti bakterije Staphylococcus aureus (ISO 22718:2015)
Ta mednarodni standard podaja splošne smernice za ugotavljanje prisotnosti in prepoznavanje bakterije Staphylococcus aureus v kozmetičnih izdelkih. Mikroorganizmi, ki so upoštevani, kot so določeni v tem mednarodnem standardu, se lahko v različnih državah zaradi državnih praks ali predpisov razlikujejo.
Za namen zagotovitve kakovosti in varnosti izdelkov za stranke je priporočljivo izvesti ustrezno mikrobiološko analizo tveganja, s katero se določijo vrste kozmetičnih izdelkov, za katere velja ta mednarodni standard. Izdelki, ki po ocenah predstavljajo nizko mikrobiološko (glejte ISO 29621) tveganje, vključujejo tiste z nizko aktivnostjo vode, hidro-alkoholne izdelke, skrajne vrednosti pH itd.
Metoda, opisana v tem mednarodnem standardu, temelji na ugotavljanju prisotnosti Staphylococcus aureus v neselektivnem tekočem gojišču (obogatitven bujon), ki mu sledi izolacija na selektivnem agarskem gojišču. Ustrezne so lahko tudi druge metode, odvisno od zahtevane ravni ugotavljanja prisotnosti.
OPOMBA: Za namen ugotavljanja prisotnosti Staphylococcus aureus je mogoče precepljene kulture vzgojiti v neselektivnem gojišču kultur, čemur sledijo ustrezni koraki prepoznavanja (npr. uporaba kompletov za prepoznavanje). Zaradi velike raznolikosti kozmetičnih izdelkov na tem področju uporabe ta metoda morda ni primerna za nekatere izdelke (npr. tiste, ki se ne mešajo z vodo). Uporabljajo se lahko drugi mednarodni standardi (ISO 18415). Druge metode (npr. avtomatske) je mogoče zamenjati za tukaj predstavljene preskuse, če je bila dokazana njihova enakovrednost ali je bila metoda drugače dokazana za primerno.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
