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.

Key words: two cultivation systems, amplified ATP bioluminescence assay, cosmetics, microorganism, suitability
