Background

Household and personal care products (H&PCPs) are used frequently in the domestic environment. Different types of H&PCPs often contain the same chemicals and have potential for aggregate exposure. Therefore, product use patterns should be investigated to assess exposure and health risk.

Results

A nationwide survey was conducted in Korea to examine the use of 16 types of H&PCPs, to obtain data that can be used for such assessments. The initial analysis focused on identifying usage patterns, such as the frequency of use and amount of product used per application. Then, co-use in 16 product categories were analyzed. Family size, marital status and age were, respectively, recognized as the critical demographic factor for classification of the frequency of use in laundry products, cleaning products and shower products. In laundry products, cleaning products and shower products, frequent H&PCPs co-use patterns according to demographical factor were recognized. Chances of exposure of chemical ingredients to participants were investigated based on the usage of individual products. 32 chemicals among all investigated ingredients were identified to be potentially exposed to more than half of the participants, and 21 chemicals are classified above Class 4 in acute toxicity.

Conclusions

Personal preference was not observed both in the use frequency and the amount per application of H&PCPs, among all participants. Instead, household duties were found to be associated with the yearly use frequency of household care products. In addition, the yearly chemical profiles of individual consumer were obtained, and the chemicals that have multiple chances of exposure and concomitant health risk in daily life were identified. The results provide the overview of distribution of chemicals in daily life, and essential ground for aggregate exposure assessment in Korea.

韩国人口使用家庭和个人护理产品的方式：对人类总暴露量和健康风险的影响

背景

家庭和个人护理产品（H＆PCP）在家庭环境中经常使用。不同类型的H＆PCPs通常包含相同的化学物质，并且有潜在的总暴露量。因此，应调查产品使用方式，以评估暴露和健康风险。

结果

在韩国进行了一项全国性调查，以调查16种H＆PCP的使用情况，以获得可用于此类评估的数据。最初的分析着重于确定使用模式，例如使用频率和每个应用程序使用的产品数量。然后，分析了16种产品类别的共同使用。家庭大小，婚姻状况和年龄分别被认为是对洗衣产品，清洁产品和淋浴产品的使用频率进行分类的关键人口统计学因素。在洗衣产品，清洁产品和淋浴产品中，人们认识到根据人口统计学因素频繁出现的H＆PCP共同使用模式。根据单个产品的使用情况，调查了参与者接触化学成分的可能性。

结论

在所有参与者中，H＆PCPs的使用频率和每次使用量均未观察到个人偏爱。相反，发现家庭职责与家庭护理产品的年度使用频率有关。此外，还获得了个人消费者的年度化学资料，并确定了在日常生活中有多次接触机会和随之而来的健康风险的化学物质。研究结果概述了日常生活中化学物质的分布，并为韩国进行总体暴露评估提供了必要的依据。
