An experiment was conducted on mask-pack, foundation, mascara and lipstick. And we measured the heavy metal concentration [ppm(μg/mg)] of As, Cd, and Pb. To see the difference of their concentrations, all tested products were classified based on price and functionality, color, and chroma specifically. The result of this study was as follows. First, both As and Pb were detected in all cosmetic products while Cd was detected in 46.7% out of tested products. Second, detected As average was as in the following. mask-pack was 0.555ppm, foundation was 0.223ppm, mascara was 0.250ppm and lipstick was 0.350ppm. So all samples were remarkably lower than standard-10ppm. Third, Cd wasn’t detected in mask-pack and lipstick. And detected Cd average was as in the following. Foundation was 0.030ppm and mascara was 0.167ppm. So they were lower than standard-5ppm. Forth, detected Pb average was as in the following. mask-pack was 26.985ppm, foundation was 10.403ppm, mascara was 8.223ppm and lipstick was 1.800ppm. In mask-pack, all samples exceeded the standard-20ppm. In foundation, only one sample of the brightest color(17) exceeded the standard. In conclusion, our predictions that the lower price product will be contained more heavy metal were inconsistent with the result. But we found correlation about functionality, color and chroma.
