In order to verify the effect of using functional cosmetic ingredients for skin beauty, the composition and content of some phenolic acid and flavonoids in the hot water and 80% methanol extract of Akebia quinata fruit pericarp and seeds were analyzed, and the skin care antioxidant activity was investigated. The results are as follows. Total polyphenol and flavonoid contents were found to be higher in pericarp extract than seed extract in both hot water and 80% methanol extract. In the analysis of the composition and content of phenolic acid and flavonoids, two kinds of phenolic acids were identified in the hot water extract of pericarp, 6 kinds of phenolic acids were identified in the 80% methanol extract, and one kind of flavonoid. Two types of phenolic acids were identified in the hot water and 80% methanol extract of seeds, respectively. DPPH and ABTS radical scavenging activities tended to increase in proportion to the treatment concentration in both hot water and 80% methanol extracts, and antioxidant activity was found to be high. Therefore, from the above results, it was found that the hot water and 80% methanol extract of Akebia quinata fruit pericarp and seeds contained various kinds of phenolic acid and flavonoids, and the antioxidant activity was also high. It is believed to be of value as a natural antioxidant in skin care cosmetic ingredients.

This study is intended to present the direction of art mask design development and help people's life care by producing an art mask with the motif of the characteristic of abjection concept. It went through the definition and characteristics of abject and abjection focusing on previous research, professional books and art works. The characteristics of abjection based on theoretical research are to express death with dead bodies and skulls, including the dismantling of ideal beauty standards, the expression of fragmented bodies, and the expression of sick and alienated bodies. This researcher produced 6 research works by combining the fascinating abjection, induced by ugly and disgusting abject, to design factors. These works fragmented each part of the facial form by the cutting and dismantling, and made viewers feel the abjection by giving a grotesque deformation. The results obtained through the research works are as follows. First, It was found that the abjection characteristics-applied works was helpful in the treatment of the mental wound of modern people. Second, the production of works based on the abjection characteristics paved the way to expand the scope of art mask design concepts and establish the new design ideas. Third, the application of the motif using the abjection characteristics to the art mask design showed that the use of various objects could express creative designs and secure diversity in using materials. In the future, this researcher hopes that such research will be used as the basic data of the follow-up study on art mask design, and it will help develop art mask designs.

The purpose of this study is to analyze whether the cosmetic interest of middle school female students(n=126) is related to purchase satisfaction by using purchase behavior and informatization level as control variables. Based on the research model, three hypotheses were set and statistical tests were conducted. The results of this study are as follows. First, middle school female students used cosmetics from elementary school and cosmetics education was requested from elementary school. Therefore proper early education on cosmetic use is needed. Second, the degree of interest and purchasing behavior of cosmetics was positively correlated with the purchase satisfaction of cosmetics. Third, the purchasing behavior of cosmetics was found to have a more effect on purchase satisfaction than the cosmetics interest. Especially, 'cosmetics purchase behavior' had a moderating effect on purchase satisfaction. Fourth, there was no difference in the average among the grades about cosmetics category(cosmetic interest, purchase behavior, informatization level, purchase satisfaction). This study needs to pay more attention to cosmetics purchasing behavior, which has the greatest effect on the satisfaction of cosmetics purchasing among middle school girls, and suggests that further studies will be continued to expand the range and ages in the future.

This study is about the development of transparent cleansing water with one of the beta-hydroxy acids (BHA), salicylic acid, and capryloyl salicylic acid, which is one of the lipo-hydroxy acids (LHA). Transparent appearance was stabilized by increasing the solubility of lipophilic salicylic acid and capryloyl salicylic acid in water using ethanol, polyol, and sodium hydroxide, and supplementing suspension and deposition using a double micelle structure of two types of PEG surfactants. Cleansing water applied with this technology was developed, and makeup removing ability and skin texture improvement ability were confirmed using an optical camera and an image analyzer. This solubilization technology is proposed as a new approach of LHA, which has been difficult to apply due to its low solubility in water, and is expected to help in the development of new chemical peeling products.

This study confirmed the followings based on analysis of language messages in 718 advertisement in , AMOREPACIFIC's beauty magazine, published from 1958 to 2018 by product categories, era, in terms of purchase information, persuasive expression, word type. First, the number of pieces among 1980s to 1990s advertisement were the largest and, in terms of product categories, there were the greatest number of pieces in skincare, makeup and mens products. Second, headline and bodycopy had a different aspect in persuasive expression. "focused on image-making" was mainly used for head lines. Specifically, "situational image" was generally dominant. While the "user image" was higher before 1990's, "brand image" was as recent times. "Informal" was mostly applied for bodycopies, especially, "general information" and "differentiated information" was used the most. It is important to know what kind of information the brand established in each brand should be embodied rather than simply dividing the appeal method into "rational appeal" and "emotional appeal."Third, persuasive expression has different aspects in headlines and body copies. "focused on image-making" was mainly used as headlines. Specifically, "situational image" is dominant. Also, "user image" was high before 1990s but "brand image" got higher in recent times. "Informal" was mostly used as body copies, especially "general information" and "differentiated information" were the most frequently selected. Therefore, it is important to apprehend which information to specify established images by brands, rather than to divide "rational appeals" and "emotional appeals". Lastly, categorizing word type into brand names and headlines, foreign language was the most dominant in brand names and Chinese characters in headline. Remarkably, brand names in native language temporarily high in 70's and 80's, which could be interpreted to be resulted from the government policy promoting native language brands in those times. In addition, foreign language was frequently used in cosmetics and Chinese characters in men's product. It could be explained that colors or seasons in cosmetic products were expressed in foreign language in most case. On the other hand, the inclination of men's product consumers, where they pursue prestige or confidence in Chinese character, was actively reflected to language messages.

This study is a mixed surfactant (MimicLipid-MSM1000) that forms the same structure as that of the stratum corneum, sucrose distearate, polyglyceryl-2 dioleate, fermented squalane, ergosterol, 10-hydroxystearic acid, mixture consisting of was synthesized. When using 2~5 wt% of this mixed surfactant, it was possible to make an artificial skin mimetic that forms a multi-layer lamellar structure of 5~30 layers. An emulsion was prepared using this mixed surfactant, and a multi-layered lamellar phase was formed and analyzed mechanically. The appearance of this surfactant was a light brown hard wax, the hydrophilic lipophilic balance (HLB) was 12.53, the critical parameter value was 0.987, and the acid value was 0.13. Stability according to pH change was also stable in acidic (3.8), neutral (7.2) and alkaline (10.8). The particle size of the liquid crystal was found to be the most stable maltese cross lamellar crystalline droplet at 5~25mm. The size of the emulsified particles according to the change in the speed of the homo agitator is 2500 rpm (17.9mm±2.6mm), 3500rpm (12.5mm±2.1mm), 4500rpm (6.2mm±1.8mm) particles were formed. Liquid crystal forming particles were observed through a polarization microscope, and the formation structure of the liquid crystal was precisely analyzed with a scanning electron microscope (cryo-SEM). As an application field, it is expected that it will be widely applicable to the development of various prescriptions, such as various skin care cosmetics, makeup care cosmetics, and scalp protection cosmetics, by using a skin-mimicking surfactant.
