摘要: 为评估基于双培养体系的ATP生物荧光增幅法在化妆品微生物快速筛查中的适用性,参照《中国药典》(2020年版)无菌检查法和微生物计数法中方法适用性试验要求,广泛选择了涵盖不同产品类型、功能宣称、作用部位、产品剂型、使用人群等20个国内外品牌的51种市售化妆品产品进行方法适用性研究,通过样品影响测试和接菌试验结果评价方法的适用性。结果表明,51种产品中有45种产品本底荧光信号值小于3倍空白培养基信号值,符合样品影响测试要求;6种产品未通过样品影响测试。将6株代表菌株按照10~100 CFU/g的终浓度接种于45种符合样品影响测试要求的产品,经双培养体系增菌培养后在42种产品中均可阳性检出;在3种产品中部分菌株未阳性检出。综上,基于双培养体系的ATP生物荧光增幅法在化妆品中微生物污染样品的快速筛查方面具有良好适用性,为化妆品生产全过程的微生物安全控制提供了高效可靠的新方法。

Abstract:

In order to evaluate the suitability of the amplified ATP bioluminescence assay based on two cultivation systems in the rapid screening of cosmetic microorganisms, 51 commercially available cosmetic products covering 20 domestic and foreign brands, including different product types, functional claims, action sites, product dosage forms, and user groups, were widely selected for method suitability research with reference to the method suitability test requirements of sterility inspection method and microbial counting method in the Chinese Pharmacopoeia (2020 Edition). And the suitability of the method was evaluated through sample impact test and spiking test results. The results show that 45 of the 51 products have a background fluorescence signal value less than 3-fold the signal value of blank medium, which meet the requirements of the sample impact test. While six products failed the sample impact test. Six representative strains are inoculated in 45 products that meet the requirements of the sample impact test according to the final concentration of 10-100 CFU/g, and are positively detected in 42 products after being cultured in the two cultivation systems. While some strains in three test products do not get positive detection results. In conclusion, the amplified ATP bioluminescence assay based on two cultivation systems has good suitability in the rapid screening of microbial contamination samples in cosmetics, and provides an efficient and reliable new method for microbial safety control in the whole process of cosmetics production.
