标准编号：ISO 21149:2006

中文名称：化妆品 微生物学 好气性、嗜温性细菌的计数及检测

英文名称：Cosmetics — Microbiology — Enumeration and detection of aerobic mesophilic bacteria

标准范围

ISO 21149:2006给出了计数和检测化妆品中存在的嗜温需氧菌的一般指南:通过在有氧培养后计数琼脂培养基上的菌落，或在富集后检查细菌生长的缺失。由于该应用领域内的化妆品种类繁多，因此该方法可能不适合于某些产品的每个细节(例如某些水不混溶的产品)。其他方法（例如自动化）可以替代此处提供的测试，前提是其等效性已得到证明或该方法已得到验证。如果需要，可以使用文献中给出的标准中描述的合适的鉴定测试来鉴定计数或检测的微生物。

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.
