面膜粉是美容化妆和皮肤护理的常用品,容易受到微生物尤其是霉菌的污染。文章根据2012~2015年间检验的65批次面膜粉霉菌总数的日常检验结果对面膜粉污染情况进行分析,合格率96.9%。并使用合并样本标准差评定检测结果的不确定度。

Facial mask powder is increasingly popular cosmetic and skin care products. Some kinds of powder could easily be contaminated by microorganism, especially contaminated by molds. To investigate the molds contamination status of facial mask powder, a total of 65 mask powder samples had been tested from 2012 to 2015. The qualified rate was 96.9 %.
