Volatile organic compounds (VOCs) are emitted from a variety of household and personal care products. Many VOCs are known to be potentially toxic or carcinogenic. Synthetic hair is used in hair-styling practices, including practices in African American communities that involve singeing or heating the synthetic hair. The research questions that we sought to answer were as follows: Are VOCs emitted from singed or heated synthetic hair? If so, what are the VOC species and relative masses identified in singed or heated synthetic hair? We tested samples from 2 sources of singed and heated synthetic hair in a microchamber; one source was flame-retardant synthetic hair and the other source was non-flame-retardant synthetic hair. Our findings confirmed that VOCs are emitted from singed or heated synthetic hair for both types of sources. For flame-retardant synthetic hair, we identified and measured mass for species that included acetone, acetonitrile, 2-butanone, benzene, chloromethane, chloroethane, and 1,2-dichloroethane. For non-flame-retardant synthetic hair, we identified and measured mass for species that included acetone, acetonitrile, chloromethane, trichlorofluoromethane, and 2-propanol.
挥发性有机化合物（VOCs）从各种家用和个人护理产品中释放出来。许多VOCs已知具有潜在毒性或致癌性。合成毛发被用于发型设计，包括非裔美国人社区中涉及烧灼或加热合成毛发的做法。我们试图回答的研究问题如下：烧灼或加热合成毛发会释放VOCs吗？如果是，在烧灼或加热的合成毛发中鉴定出的VOC种类和相对质量是多少？我们在一个微室内测试了来自2个烧灼和加热合成毛发来源的样本；一个来源是阻燃合成毛发，另一个来源是非阻燃合成毛发。我们的研究结果证实，两种类型的来源在烧灼或加热合成毛发时都会释放VOCs。对于阻燃合成毛发，我们鉴定并测量了包括丙酮、乙腈、2-丁酮、苯、氯甲烷、氯乙烷和1,2-二氯乙烷在内的物质的质量。对于非阻燃合成毛发，我们鉴定并测量了包括丙酮、乙腈、氯甲烷、三氯氟甲烷和2-丙醇在内的物质的质量。
