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.

Due to continuous environmental pollution, the use of shower filters in routine life is increasing, and the number of patients is steadily increasing due to rust in aging pipes and various bacteria and viruses17 that inhabit underground water. In addition, huge budgets and processes are being invested in the operation of the water purification system, but there is still growing anxiety over drinking water and living water. Various products including vitamins and scents are introduced in shower filters, but generally, the filter cycle is short or the stored water causes germs. Therefore, this study conducted a study on functional antibacterial balls that showed antibacterial function even when water was stored using a 3D printer. In this study, in order to manufacture antibacterial balls in shower filter, the balls of PLA, PE, and PETG were first manufactured with 3D printer, and 0.01M and 0.05M diazonium salts were bonded on to the surface of the balls of each material, and the antimicrobial coating was carried out through metal adhesive reaction. Antibacterial balls coated with antibacterial on each material are expected to maintain antibacterial properties for a long time, as they have been formed through chemical displacement-sharing bonds unlike conventional ceramic antimicrobial balls. In this study, the Fourier transform infrared spectroscopy(FT-IR) analysis7-11 confirmed that diazonium salts were well bonded to each plastic surface, and that 0.05M diazonium salts were more than 7 times the gatzonium salts on the plastic ball surface. In addition, the analysis of antimicrobiality by Spectrophotometer confirmed that all three types of plastics coated with 0.05M diazonium salt do not proliferate after an hour. The results of this study are expected to show excellent antibacterial effects if anti-bacterial balls are applied to household water and drinking water as well as shower filters.

In this study, the effect of hair brushing on reducing dandruff and enhancing hair gloss, which is an indicator of hair health, was examined. Hair brushing is a technique that can be incorporated into a daily routine to promote scalp health and prevent hair loss in a busy schedule. Hair brushing is a technique that can be incorporated into a daily routine to promote scalp health and prevent hair loss in a busy schedule. All participants used the same shampoo, provided with instructions on how to use the brush as part of their home care routine for a period of 30 days. Prior to the experiment, researchers conducted a survey to assess participants' expectations, targeting 20 individuals of both genders aged in their 20s to 60s. The results showed that 65.0% of participants responded positively, with an average rating of 3.95 out of 5. Statistical significance was verified through a comparative analysis of average hair gloss measured before and after the experiment using the MPA6 MDD4 Scalp Glossymeter GL200 Probe (Germany). The average hair gloss increased from 2.25 points before the experiment to 2.79 points after the experiment, showing a statistically significant difference. The results showed a statistically significant difference (t=-5.273, p<.05). In addition, a comparative analysis of images for scalp desquamation (using COMSCAM UBS 225, Korea) visually confirmed a significant decrease. Additionally, it was observed that the participants had positive expectations regarding the beneficial effects of using a hairbrush before shampooing to manage dry scalp and promote scalp health. Participants expressed the highest intention to continue using the hairbrush with a score of 4.50, and it was noted that they also had a high intention to recommend the hairbrush to others with a score of 4.40. This appears to be the result reflecting the effects of hair brushing and psychological satisfaction. All six satisfaction items, including the two mentioned above, showed satisfaction scores exceeding the median of 3 points, indicating a high satisfaction level with the effectiveness and user experience of the hairbrush.
