Abstract

Four children's cosmetic sets were purchased online, labeled for use from 4 years of age, and 81 components of each were analyzed for lead, cadmium, arsenic, antimony, nickel, cobalt, copper, chromium, and mercury by inductive coupled plasma - mass spectrometry (ICP - MS). The average metal concentrations were as follows: 0.82 ㎍/g for lead, 0.03 ㎍/g for cadmium, 0.97 ㎍/g for arsenic, 0.52 ㎍/g for antimony, 2.32 ㎍/g for nickel and 0.01 ㎍/g for mercury which was lower than the acceptable standards for all products. Higher mean values of lead, antimony, cobalt, and copper were detected in imported than domestic products (p < 0.05). There was a statistically significant difference in the average values of heavy metals according to the type of cosmetics (p < 0.05), with eyeshadow showing the highest mean values of arsenic 2.47 ㎍/g, nickel 6.36 ㎍/g, and chromium 11.06 ㎍/g. and the highest mean concentrations were 1.20 ㎍/g for lead, 1.17 ㎍/g for antimony, and 23.60 ㎍/g for copper in blusher. The levels of cobalt in the 81 children's cosmetics were ND ~ 5.23 ㎍/g, copper were ND ~ 379.61 ㎍/g, and chromium were detected ND ~ 36.95 ㎍/g, respectively. Brown colored cosmetics had the highest mean concentrations of nickel and cobalt. Purple-colored cosmetics had the highest mean concentration of lead and chromium.

사용 연령이 만 4 세 이상부터 표시된 어린이 화장품세트 4 건을 온라인으로 구매하였으며 각 구성품 81 건을 대상으로 납, 카드뮴, 비소, 안티몬, 니켈, 코발트, 구리, 크롬 및 수은의 함량을 inductive coupled plasma-mass spectrometry (ICP - MS)로 분석하였다. 어린이 화장품의 중금속 평균값은 납 0.82 ㎍/g, 카드뮴 0.03 ㎍/g, 비소 0.97 ㎍/g, 안티몬 0.52 ㎍/g, 니켈 2.32 ㎍/g, 수은 0.01 ㎍/g으로 모든 제품에서 허용 기준보다 낮았다. 국산과 수입산의 비교 결과, 국산보다는 수입산에서 납, 안티몬, 코발트, 구리의 평균값이 높게 검출되었다(p < 0.05). 화장품 유형에 따른 중금속 평균값은 통계적으로 유의한 차이를 보였는데(p < 0.05) 아이새도에서 비소 2.47 ㎍/g, 니켈 6.36 ㎍/g, 크롬 11.06 ㎍/g으로 평균값이 가장 높게 나왔으며, 볼연지에서 납 1.20 ㎍/g, 안티몬 1.17 ㎍/g, 구리 23.60 ㎍/g으로 가장 높게 나왔다. 분석된 81 건의 어린이 화장품에 대한 코발트의 검출 수준은 불검출 ~ 5.23 ㎍/g, 구리는 불검출 ~ 379.61 ㎍/g, 크롬은 불검출 ~ 36.95 ㎍/g이었다. 브라운 색상의 화장품은 니켈과 코발트에서 평균값이 높게 검출되었으며, 퍼플 색상은 납과 크롬에서 높게 검출되었다.
