ISO 21148:2017给出了化妆品微生物检查的一般说明，以确保其质量和安全，并根据适当的风险分析（例如低水活性、水酒精、极端pH值）。 由于产品种类繁多，且在该应用领域具有潜在用途，因此这些说明可能不适用于某些产品的所有细节（例如某些水不溶性产品）。

ISO 21148:2017 gives general instructions for carrying out microbiological examinations of cosmetic products, in order to ensure their quality and safety, in accordance with an appropriate risk analysis (e.g. low water activity, hydro-alcoholic, extreme pH values). Because of the large variety of products and potential uses within this field of application, these instructions might not be appropriate for some products in every detail (e.g. certain water-immiscible products).
