摘要

有人认为,松发剂是接触对羟基苯甲酸酯和邻苯二甲酸酯的一个来源。然而,消费者使用松发剂导致皮肤吸收这些化学物质的剂量尚未得到量化,而且流行病学研究结果一致表明,黑人妇女使用松发剂不会增加罹患对激素敏感的生殖系统癌症的风险。因此,我们使用 IH SkinPerm™ 对几种市售松发剂套件中与使用松发剂有关的对羟基苯甲酸酯和邻苯二甲酸酯的皮肤吸收进行了模拟。在松发剂套装中检测到的化学物质包括对羟基苯甲酸甲酯 (MP)、对羟基苯甲酸乙酯 (EP)、对羟基苯甲酸丁酯 (BP)、邻苯二甲酸二乙酯 (DEP)、邻苯二甲酸二(2-乙基己基)酯 (DEHP) 和邻苯二甲酸酯替代物己二酸二(2-乙基己基)酯 (DEHA)。产品使用一年后的标准日吸收剂量范围(毫克/千克/天)如下:试剂盒 #1 的日吸收剂量范围(毫克/千克/天)如下:8.64 × 10-5-0.00116 MP、2.30 × 10-8-3.07 × 10-6 EP、3.24 × 10-8-4.33 × 10-6 BP、8.65 × 10-9-1.15 × 10-6 DEP 和 8.94 × 10-7-0.000119 DEHP;试剂盒 #2 的日吸收剂量范围(毫克/千克/天)如下:8.44 × 10-5-0.00113 MP 和 7.试剂盒#2:8.44 × 10-5-0.00113 MP 和 7.91 × 10-5-0.00106 DEP;试剂盒#3:2.49 × 10-6-3.33 × 10-5 MP、1.52 × 10-8-2.03 × 10-6 EP、3.29 × 10-9-4.39 × 10-7 DEP 和 3.11 × 10-6-4.14 × 10-5 DEHA。这些吸收剂量远低于适用的基于健康的指导值,表明消费者因使用产品而接触这些物质预计不会造成健康风险。这些结果为松发剂使用的健康风险评估提供了有价值的信息。

Evaluation of dermal exposure to phthalates and parabens resulting from the use of hair relaxers.

Hair relaxers have been suggested as a source of exposure to parabens and phthalates. However, dermally absorbed doses of these chemicals resulting from consumer use of hair relaxers have yet to be quantified, and results from epidemiological studies have consistently demonstrated that there is no increased risk for hormone-sensitive, reproductive cancers associated with use of hair relaxers among Black women. Therefore, dermal absorption of parabens and phthalates associated with hair relaxer use for several commercially available hair relaxer kits was modeled using IH SkinPerm™. The chemicals detected in the hair relaxer kits included methylparaben (MP), ethylparaben (EP), butylparaben (BP), diethyl phthalate (DEP), bis(2-ethylhexyl) phthalate (DEHP), and the phthalate substitute bis(2-ethylhexyl) adipate (DEHA). The daily absorbed dose ranges (mg/kg/day), standardized over a year of product use, were as follows: 8.64 × 10-5-0.00116 MP, 2.30 × 10-8-3.07 × 10-6 EP, 3.24 × 10-8-4.33 × 10-6 BP, 8.65 × 10-9-1.15 × 10-6 DEP, and 8.94 × 10-7-0.000119 DEHP for Kit #1; 8.44 × 10-5-0.00113 MP and 7.91 × 10-5-0.00106 DEP for Kit #2; and 2.49 × 10-6-3.33 × 10-5 MP, 1.52 × 10-8-2.03 × 10-6 EP, 3.29 × 10-9-4.39 × 10-7 DEP, and 3.11 × 10-6-4.14 × 10-5 DEHA for Kit #3. These absorbed doses were well below applicable health-based guidance values, indicating consumer exposure from product use is not expected to pose a health risk. These results provide valuable information for health risk evaluations for hair relaxer use.

期刊介绍: International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
