This study was carried out to evaluate the possibility of willow plants (the genus Salix) as a cosmetic material. DPPH radical scavenging abilities of 70% ethanol extracts of S. gracilistyla, S. pseudolasiogyne, and S. koriyanagi were significantly increased compared to control. In addition, the treatment of three species of willow plant extracts significantly inhibited the production of nitric oxide (NO) in RAW 264.7 cells, indicating that they had anti-inflammatory activity, and all of them had collagenase inhibitory activity. Among them, the extracts of S. gracilistyla extracts exhibited the highest collagenase inhibitory activity. As a result of analyzing the collagenase inhibitory activity against the solvent fraction of S. gracilistyla extracts, water and butanol fractions showed the highest collagenase inhibitory activity. These results suggested that S. gracilistyla among the willow plants had high collagenase inhibitory activity, and thus it can be utilized for cosmetics as an effective functional cosmetic material in the future.

We often use the KCID(Korean Cosmetic Ingredient Dictionary) and ICID(International Cosmetic Ingredient Dictionary) within cosmetics research and within their export and import. so far, we do not have a database of a cosmetics' raw materials. Because of this, we consume a lot of time to find the raw material data that is needed. This study constructs a cosmetics' raw material database and develops the program to retrieve it. We used a Linux machine as the equipment for this study and we used Apache web server, MySQL database server and PHP as the tools of this study. 11,817 kinds of raw materials data were registered as ICID, 866 kinds of raw materials data were registered as KCID and 28,008 kinds of raw materials data with registered trade name into the database. Also, The database was composed of the database of the association form. The database of the online form could ultimately reduce the task time as soon as it did its purpose. The product of this study can become a good basis of data to reconfigure. In the future, it can become a good database in relation with different databases.

In this study, anti-oxidant, whitening and anti-aging effects were investigated the possibility of fermented black tea yeast as a functional cosmetic material. The results of Aureobasidium pullulans (A. pullulans) ferment of black tea (AFBT) were compared with black tea (BT) and A. pullulans ferment (AF). The antioxidant activity of the AFBT product showed DPPH radical scavenging ability higher than that of AF. In the intracellular ROS experiments induced by hydrogen peroxide, the AFBT showed significant decreased activity. In addition, AFBT showed tyrosinase inhibitory activity and inhibited the formation of melanin using Melan-a and B16F10 cells. Through suppression of MMP-1 expression, the AFBT showed higher anti-wrinkle activity than BT and AF. From the results of this study, it was confirmed that AFBT showed antioxidant activity and was developed as a functional cosmetic material based on whitening and anti-wrinkle efficacies.

This study attempted to investigate the possibility of Passiflora caerulea extract as a cosmetic material by measuring its antioxidant activities and melanin biosynthesis-inhibiting effects. For this, the substance was extracted with 70% ethanol, and ABTS radical scavenging activities were measured, using the TEAC assay. In addition, cell viability through the neutral red assay, ROS inhibition and inhibition of melanin biosynthesis were analyzed, and the results found the followings: In terms of ABTS radical scavenging activities of the extract, dose-dependent scavenging activities were observed. In trolox used as a positive control group and 0.1 mg/mL, similar radical scavenging activities were found. The production of ROS through CFDA was inhibited in a dose-dependent fashion. Furthermore, inhibition of melanin biosynthesis induced by 𝛼-MSH was confirmed. Therefore, it is reasonable to conclude that Passiflora caerulea extract has a potential as a cosmetic ingredient.

Particulate matter and ultra-particle matters generally refer to very small floating dust, such as 1/6 to 1/7 and 1/20 to 1/30, respectively, compared to the thickness of human hair, and contain various types of heavy metal ions. In addition to breathing, particle matters (PM) that flows in through the gaps in the pores of the skin can induce health problems in the body's tissues and skin, so it must be removed by blocking the inflow or by washing. Through this study, we confirmed the possibility that heavy metal ions can be adsorbed and removed by using Oryza sativa (Rice) bran oil (OSBO). In addition, the cell viability is much higher than that of grain-derived components through cytotoxicity experiments, and the cytoprotective effect of an external stimulus source can be expected. It was confirmed that the expression amount of COL1A1 mRNA increased, and accordingly, it was believed that wrinkles that might be caused by moisture lost by heavy metal ions in fine dust could be alleviated. Based on the results of these experiments, we tried to present a cosmetics containing OSBO, which is a wash-off formulation, in order to finally remove heavy metals.

Recently, enviromentally friendly natural substances derived from plants have been attracting attention as cosmetic materials, and research on various physiological activities of natural substances is being actively conducted. This study investigated the antioxidant, anti-inflammatory, moisturizing, and antibacterial effects of three types of extracts of mixtures containing different mixing ratios, Polygala tenuifolia, Angelica dahurica, and Elsholtzia splendens, known to have various physiological activities. The mixing ratio is 7 conditions (M1, 1:1:1; M2, 0.5:1.5:1; M3, 1.5:0.5:1; M4, 0.1:0.95:0.95; M5, 0.5:0.5:2; M6, 0.95 :1.95:0.1; M7, 1.45:0.1:1.45), and the optimal mixing ratio was confirmed for use as a cosmetic material. DPPH and ABTS radical scavenging activities showed scavenging abilities of 75.37% and 99.19%, respectively, at 1,000 ㎍/mL of M6. At a concentration of 200 ㎍/mL of M6, it showed 50% of nitric oxide production inhibition compared to the lipopolysaccharide-treated that induced an inflammatory response. It was confirmed that M3 and M6 produced hyaluronic acid 1.47 and 1.49 times higher than the control at a concentration of 50 ㎍/mL, respectively. Through the disc diffiusion test, the clear zone was 9.75 mm at 8 ㎍/mL of M6, confirming the inhibition of growth of staplylococcus aureus strain. Based on the above results, it is believed that the mixed extract of Polygala tenuifolia, Angelica dahurica, and Elsholtzia splendens can be used as a functional natural material for cosmetics.
