Cosmetics are products that come into direct contact with the skin, which inevitably leads to high interest in natural ingredients that are harmless to the human body. Among these natural cosmetics, many basic cosmetics such as skin lotion are on the market, but mascara products, which are color tone cosmetics, are not noticeable. Mascara is a colored cosmetic that has strong contact with the eyes to stimulate the health of the eye. In particular, the use of mascara has many examples of eye health problems, which are analyzed for the effects of heavy metals contained in raw materials used in colorimetric materials.In this study, we applied research on coffee beans, which are natural materials instead of black iron oxide used as black pigment in mascara, and studied the possibility of products as mascara and the safety of heavy metals. The coffee bean extract extracted from 60-90% ethanol was analyzed by Gas chromatography-mass spectrometry (GC-MS) at the first stage. In 90% ethanol, various other ingredients besides caffeine are detected, and the detected ingredients decrease as the proportion of ethanol decreases. As a second step, mascara was produced using coffee beans extracted with ethanol. For mascara production, for comparative analysis, black iron oxide which is a raw material of commercially available mascara and coffee bean extract extracted with ethanol were produced and compared and analyzed. In the third step, the functional aspects of commercially available mascara and coffee bean mascara were confirmed and the substance properties were compared and analyzed. The color tone was measured using a color difference meter and the viscosity was analyzed using Viscometry. In the fourth step, mascara made of bean extract was analyzed by inductively coupled plasma mass spectrometry (ICP-MS) to determine heavy metals including Lead (Pb), Nickel (Ni), arsenic (As). As a result, the manufactured mascara identified a tendency for the heavy metal content to decrease as the raw bean extract content increases.The results of this study showed that color and texture of coffee bean - containing mascaras were not significantly different from commercial mascaras. And Through ICP-MS analysis, the content of heavy metals is lower than that of graphite iron. ATherefore, as a result of this study, mascara containing the proto-head extract can be applied as a natural mascara and is expected to be applied to the research of color tone cosmetics such as mascara in the future.
