摘　　要：目的:分析新疆地区消费市场牙膏中含有可溶氟与游离氟的情况,以期为化妆品监管提供参考。方法:依据国家标准《牙膏》(GB/T 8372-2017)对抽取的100批次牙膏样品进行检测,并对检测结果进行统计和分析。结果:可溶氟含量主要在0.05%~0.11%范围之间,游离氟含量主要在0.004%~0.13%范围之间,无不合格样品。结论:虽然含氟牙膏中的可溶氟与游离氟的含量均符合国家标准的限值要求范围,但部分样品的可溶氟含量在标准要求下限(0.05%)附近,且部分样品存在实际检测情况与标签标识不符的情况,存在风险,建议相关部门持续加强监督管理。Objective:To analyze the level of soluble fluoride and free fluoride in toothpaste in local consumer products market,and to provide evidence for cosmetics supervision.Methods:According to the national standard GB/T 8372-2017,100 batches of toothpaste samples were tested,and the results were analyzed.Results:Soluble fluorine content was mainly in the range of 0.05%~0.11%,and free fluorine content was mainly in the range of 0.004%~0.13%.There were no unqualified samples.Conclusion:The levels of soluble fluorine and free fluorine in fluoride-containing toothpaste all meet the limits of national standard.However,the level of soluble fluorine in some samples was close to 0.05%,which is the lower limit of the standard requirements,and inconsistencies were found between the testing results and the labels of some samples.These risk signals warrant continued oversight by relevant regulatory authorities.
