Cosmetics — Microbiology — Enumeration and detection of aerobic mesophilic bacteria
ISO 21149:2006 gives general guidelines for enumeration and detection of mesophilic aerobic bacteria present in cosmetics:
- by counting the colonies on agar medium after aerobic incubation, or
- by checking the absence of bacterial growth after enrichment.
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 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.
If needed, microorganisms enumerated or detected may be identified using suitable identification tests described in the standards given in the Bibliography.

Frequently Asked Questions about ISO 21149:2006
When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.
Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
If you have an extensive portfolio of standards, we recommend using a professional standards management tool. With effects 2.0, you can manage your standards centrally and efficiently. You can optimise your procurement processes and benefit from an integrated information and subscription service. This ensures you are always up to date and never miss any relevant developments.
