Abstract
2013년 1월에서 8월 사이에 전국에서 유통 중인 립스틱, 립글로스, 립밤, 파운데이션, 아이라이너 등 색조화장품 121개 제품에서 납, 카드뮴, 비소, 크롬, 안티몬, 니켈, 구리 및 코발트의 농도 측정과 국산 및 수입산, 유형별, 색상별로 비교함으로써 이와 관련된 분야의 기초자료를 제공하고자 본 연구를 시행하였다. 분석된 전체 색조화장품의 중금속 평균 농도는 납 <TEX>$0.663{\mu}g/g$</TEX>, 카드뮴 <TEX>$0.010{\mu}g/g$</TEX>, 비소 <TEX>$0.056{\mu}g/g$</TEX>, 크롬 <TEX>$1.144{\mu}g/g$</TEX>, 안티몬 <TEX>$0.008{\mu}g/g$</TEX>, 니켈 <TEX>$0.405{\mu}g/g$</TEX>, 구리 <TEX>$0.319{\mu}g/g$</TEX> 및 코발트 <TEX>$0.108{\mu}g/g$</TEX>으로 측정되었다. 국산 및 수입산 색조화장품은 통계적으로 유의한 차이를 보였으며(p < 0.05), 수입산이 크롬을 제외한 7개 금속에서 국산보다 높게 검출되었다. 색조화장품의 유형에 따른 중금속 농도는 통계적으로 유의한 차이를 보였으며(p < 0.05), 립스틱에서 크롬 <TEX>$1.430{\mu}g/g$</TEX>, 납 <TEX>$0.616{\mu}g/g$</TEX> 그리고 니켈 <TEX>$0.385{\mu}g/g$</TEX>이 파운데이션에서 납 <TEX>$1.155{\mu}g/g$</TEX>, 크롬 <TEX>$1.023{\mu}g/g$</TEX>이 가장 높은 농도를 보였으며, 아이라이너에서는 크롬 <TEX>$1.424{\mu}g/g$</TEX>, 니켈 <TEX>$0.830{\mu}g/g$</TEX>이 가장 높은 농도를 나타내었다. 색조화장품의 색상별 중금속 농도는 통계적으로 유의한 차이를 보였으며(p < 0.05), 갈색의 화장품은 크롬, 니켈과 구리가 높은 평균 농도를 보였고, 아이보리색의 화장품은 납과 크롬이 핑크색의 화장품은 크롬과 납이 높은 평균 농도를 나타내었다. This study aimed to provide the fundamental data on the field of cosmetics by comparing heavy metal concentration in terms of domestic/foreign products, types and colors. The study determined the concentrations of lead, cadmium, arsenic, chromium, antimony, nickel, copper and cobalt in cosmetics such as lipstick, lip gloss, lip balm, foundation and eye liner. From the period of January to August, 2013, 121 samples were collected from cosmetic stores distributing to the general market. The average metal concentrations were as follows; <TEX>$0.663{\mu}g/g$</TEX> for lead, <TEX>$0.010{\mu}g/g$</TEX> for cadmium, <TEX>$0.056{\mu}g/g$</TEX> for arsenic, <TEX>$1.144{\mu}g/g$</TEX> for chromium, <TEX>$0.008{\mu}g/g$</TEX> for antimony, <TEX>$0.405{\mu}g/g$</TEX> for nickel, <TEX>$0.319{\mu}g/g$</TEX> for copper and <TEX>$0.108{\mu}g/g$</TEX> for cobalt. Except for chromium, the heavy metal concentrations were significantly higher in foreign products than in domestic products (p < 0.05). Also, The mean concentrations of heavy metal were significantly different (p < 0.05) when classified by cosmetic type. The highest mean concentrations shown in lipstick were <TEX>$1.430{\mu}g/g$</TEX> of chromium, <TEX>$0.616{\mu}g/g$</TEX> of lead and <TEX>$0.385{\mu}g/g$</TEX> of nickel, in foundation <TEX>$1.155{\mu}g/g$</TEX> of lead and <TEX>$1.023{\mu}g/g$</TEX> of chromium. In eye liner, the highest mean concentrations were <TEX>$1.424{\mu}g/g$</TEX> of chromium and <TEX>$0.830{\mu}g/g$</TEX> of nickel. Additionally, The concentrations of heavy metal were significantly different by color (p < 0.05). Brown colored cosmetics were found to have the highest mean concentrations of chromium, nickel and copper, ivory colored cosmetics the highest mean concentrations of chromium and lead, and pink colored cosmetics the highest concentrations of lead and chromium.
