Formaldehyde, a natural component of all mammalian cells, is metabolized to carbon dioxide. It is a colorless gas used as a preservative and a reactant in chemical processes in a wide variety of commercial and consumer products. Toluene is an organic solvent also used in a wide variety of commercial and consumer products. There is a growing concern that chemical exposure from consumer products including cosmetics adds to the overall toxic exposure bioburden. This study was designed to quantify the actual amount of formaldehyde and toluene exposure to professional nail technicians and their customers during the application of cosmetic nail products containing either formaldehyde or toluene. Formaldehyde concentrations were measured on workers and consumers using treated silica gel absorption tubes. Formaldehyde concentrations varied between 0.0012 and 0.0038 ppm. The results of this study clearly demonstrate that neither workers nor consumers are at any additional risk from exposure to formaldehyde or toluene in cosmetic nail products beyond daily exposure from commercial products in a work setting and in the home.
甲醛是所有哺乳动物细胞的天然成分，会被代谢为二氧化碳。它是一种无色气体，在多种商业和消费品中用作防腐剂和化学过程中的反应物。甲苯是一种有机溶剂，也用于多种商业和消费品中。人们越来越担心包括化妆品在内的消费品中的化学物质暴露会增加整体有毒暴露生物负担。本研究旨在量化在使用含有甲醛或甲苯的美甲产品过程中，专业美甲师及其顾客实际接触甲醛和甲苯的量。使用经处理的硅胶吸收管测量工人和消费者身上的甲醛浓度。甲醛浓度在0.0012至0.0038 ppm之间变化。这项研究的结果清楚地表明，无论是工人还是消费者，除了在工作场所和家庭中因商业产品造成的日常暴露外，接触美甲产品中的甲醛或甲苯不会面临任何额外风险。
