Abstract
In order to estimate the realistic exposure of a chemical, aggregate exposure from multiple consumer products should be considered. Typical aggregate exposure assessment was a form of the simply combined amount of exposure by product. Accurate aggregate exposure assessment should be based on individual’s exposure factors and actual chemical contents in products. The aims of this study were to estimate aggregate exposure of Di(2-ethylhexyl)phthalate (DEHP) in multiple cosmetic products by Korean population group and determine the contribution of each product.We collected the exposure factors of 12 cosmetic types (four skincare, three hair care, three body care, and two cleansing products). Field survey staff visited homes and collected product use information using face-to-face interview. In total, 1,001 subjects over 19 years old completed the questionnaire from June to August 2017. The number of subjects was determined by proportionate quota sampling based on the population composition ratio in sex and age distribution. DEHP concentrations for 111 products from the 12 product categories were analyzed by GC-MS/MS.The exposure factor survey showed that 96.4% of the 1,001 subjects used at least one cosmetic product. The detection frequency of DEHP in the cosmetic products was 61.3% and maximum concentrations were 18.6 µg/g at 34 skincare, 24.0 µg/g at 15 hair care, 122.9 µg/g at 23 body care and 75.2 µg/g at 39 cleansing products. The average aggregate DEHP exposure based on individual’s exposure factors was 2.97 ± 4.00 µg/kg-bw/day in Korea population. The 30’s women group was the group of the highest aggregate DEHP exposure with 5.21 ± 6.17 µg/kg-bw/day which was 6.86 times higher than 60’s men group. DEHP exposure contribution by products was in order of body cream, facial cleanser and facial cream.These aggregate exposure data would be useful input data for risk assessment and regulation of DEHP in cosmetic products.
