691例化妆品微生物检测结果分析

Analysis on Microbiological Results of 691 Cosmetics

目的检测化妆品的微生物指标,分析污染微生物的种群分布,了解化妆品的卫生情况及其中存在的潜在危害。方法按照《化妆品卫生规范》(2007版)第四部分—微生物检验方法检测化妆品中微生物指标,并将检出的细菌分离,利用VITEK2全自动微生物鉴定仪进行鉴定。结果 691例化妆品的合格率为99.13%,菌落总数合格率为99.42%,霉菌和酵母菌合格率为100%,检出粪大肠菌群1例,铜绿假单胞菌1例、未检出金黄色葡萄球菌。菌属分布主要为假单胞菌属、埃希菌属、泛菌属、气单胞菌属、葡萄球菌属等,分离出的细菌多数为条件致病菌,对使用者的健康可能造成危害。结论化妆品的微生物指标超标率较低,但是有致病菌和条件致病菌检出,说明化妆品的卫生安全问题仍不容忽视。

Objective To investigate the contamination of bacteria in cosmetics and their potential hazards. Methods The microbiological indexes were tested according to the microbiological testing methods in the fourth part of the Hygienic Standard for Cosmetics： （2007） ,and the isolated strains were identified by an automatic sys- tem Vitek2. Results The qualified rate of 691 cosmetics was 99. 13% , the qualified rate for aerobic bacteria counts was 99.42%, and the qualified rate for yeasts and molds was 100%. Fecal coliform bacteria was detected in one sample, pseudomonas aeruginosa was detected in one sample, and no staphylococcus aureus was detected in all samples. The distribution of bacteria species was mainly pseudomonas, escherichia, pantoea spp, aeromonas and staphylococcus. Most of them were conditional pathogens, which might do harm to the health of consumers. Conclusions The exceeding standard rate for microbiology was low in these 691 cosmetics, but some pathogens and conditional pathogenic bacteria were detected. The issue on the health and safety of cosmetics could not be ignored.
