Cosmetics have mild activity on the human body, and intended to be used for cleaning, beautifying the human body, and also keeping healthy skin or hair, promoting attractiveness or altering the appearance. Functional cosmetics, in other words cosmeceuticals, are restricted for following functions: 1) Whiten the skin tone by preventing deposition of melanin pigmentation or lightening of the color of melanin of skin, 2) alleviate or improve wrinkles of the skin, and 3) protect the skin from the ultra violet rays from the sun. According to the functions of the functional cosmetics, skin whitening products, anti-wrinkle products, and suntan & sunscreen products are manufactured. In order to manufacture and import the functional cosmetics in Korea, the approval process in KFDA is necessary. The review process in KFDA is performed based on The Korea Food and Drug Administration Notification 2007-44, "The Regulation of Reviewing the Functional Cosmetics" (June 29, 2007). Only after the approval of KFDA, functional cosmetics are allowed to advertise to the consumers for their functionality.

Methylisothiazolinone (MIT) and chloromethylisothiazolinone (CMIT) cause allergic contact dermatitis and are banned cosmetics ingredients, except in rinse-off products. However, their presence has been detected in cosmetics. We report a UPLC-tandem MS/MS screening method for their simultaneous determination in cosmetics. To facilitate extraction from various matrices, pretreatment methods were developed for each sample type. The method was optimized through a series of assessments, including specificity, LOD, LOQ, linearity, recovery, stability, precision, and accuracy. The LODs and LOQs for MIT ranged from 0.054 and 0.163 ㎍ mL^-1 whereas those for CMIT ranged from 0.040 and 0.119 ㎍ mL^-1. The linear correlation coefficients (r²) were higher than 0.999. Relative standard deviations (RSDs) for both intra- and inter-day measurements ranged from 0.3 ~ 13.6 %. Recoveries at three different concentrations were within 87.9 ~ 118.9 %. The RSD for stability measurements of spiked samples was within 7 %. These results confirm the suitability of the developed method for the simultaneous quantitation of MIT and CMIT in cosmetics. Samples of 320 color cosmetics, including eyeshadows, solid lipsticks, liquid lipsticks, and nail polishes were analyzed using the developed method, and two of them were found to contain both MIT and CMIT and one of them was found to contain only MIT. This data and the method will aid the regulation of ingredients used in cosmetics.

This study examines the effects of evaluation criteria for natural cosmetics on purchase and word-of-mouth intentions according to the LOHAS class. A survey was conducted from Feb. 2 to 17, 2013 and a total of 410 responses were analyzed using SPSS 18.0. The results of this study are described below. First, evaluation criteria for natural cosmetics had four dimensions - practical, aesthetic, promotional, and social criteria. Second, for the upper LOHAS class, all four dimensions of evaluation criteria for natural cosmetics were important relative to the middle and lower classes. Third, for the upper and middle LOHAS classes, purchase intentions were influenced by practical criteria. However, evaluation criteria had no effect for the lower LOHAS class. Fourth, the upper LOHAS class considered practical criteria, the middle LOHAS class considered practical and social criteria, and the lower LOHAS class considered aesthetic criteria, As a result, word-of-mouth intentions were influenced by evaluation criteria for natural cosmetics.

The Purpose of the current study is to investigate the differences in cosmetics attribute evaluation, purchase motivation, and brand re-purchase intention with respect to shopping orientations of Korean female university students. Questionnaires were distributed to 250 female students at Kyungpook National University and 220 completed questionnaires were analyzed. The results were as follows. First, shopping orientations and cosmetics attribute evaluation each generated four factor solutions, whereas cosmetics purchase motivations produced three factors. Second, three consumer groups - Efficiency Shopper Group, Indifference Shopper Group Ambivalence Shopper Group - with different shopping orientations were identified. Third, the study found significant differences in consumers' attribute evaluation such as function and price among the groups. The study also revealed a significant difference in contingent purchase motivations and brand re-purchase intention among the groups. From these results, we could identify that cosmetics re-purchase intention was significantly different among three different groups with different shopping orientations. Furthermore, consumer classification according to shopping orientations in cosmetics product purchase can be used by cosmetics marketers and managers to establish product plan and marketing strategy development. Additionally, the current study has originality and value that the relationship between shopping orientation and re-purchase intention has not been studied very much in the cosmetics product domain.

The purpose of this study is to examine the influence of expected values for appearance management on interest in make-up and cosmetics evaluation criteria. Questionnaires are being administered to 244 college students from the Deagu Metropolitan City and Kyungbook province. The frequency, factor analysis, reliability analysis, regression analysis, and t-test are used for data analysis. Expected values of appearance management are categorized into pleasure/satisfaction, other-expectancy, power value and conformity. Interest in make-up factors are found to be leadership in make-up, others-oriented, and appearance satisfactions. Cosmetics evaluation criteria are categorized into 4 factors such as skin suitability, pursuit of utility, non-essential attributes and symbolism. Pleasure/satisfaction, and conformity are the sub-variables of expected values for appearance management and have significant effects on leadership in make-up and others-oriented sub-variables for interest in make-up. Pleasure/satisfaction, and conformity, being the sub-variables of expected values for appearance management, have significant effects on skin suitability, the sub-variables of cosmetics evaluation criteria. And conformity has significant effects on symbolism, the sub-variables of cosmetics evaluation criteria. This indicates that women show high conformity for expected values of appearance management, leadership in make-up and others-oriented sub-variables for interest in make-up, and skin suitability of cosmetics evaluation criteria.

The purpose of this study is to classify men's fashion leadership into groups and analyzed the differences for the actual conditions of cosmetics purchasing and evaluation criteria. Questionnaires are being administered from 163 men in their 20's and 30's living in Deagu Metropolitan City and Kyungbook. Frequency, factor analysis, reliability analysis, cluster analysis, ANOVA, Duncan-test, and $X^2$-test are all used for data analysis. Our findings are as follows. Men's fashion leadership is being categorized into fashion opinion leadership, innovative communicator and fashion innovator. Cosmetics evaluation criteria are service/aesthetic, ostentatious, function, and economy. Men's fashion leadership is classified into three groups: fashion laggards, fashion leaders, and fashion followers. Males show no significant differences in the function of cosmetics evaluation criteria by the groups but they show significances in service/aesthetic, ostentatious, and economy. Groups display distinctions between the sub-variables in the actual condition of cosmetics purchasing such the place of purchase, companionship when buying cosmetics, and average monthly purchase amount. Although the cosmetic markets for men show high average growth rates per year, cosmetic interests at the age of twenties and thirties are generally low, and cosmetics are not actively used. The customers' experience of using merchandise not only provide the opportunities of trying beforehand, but also lead to the role of information transfer, thus, it can be positively applied to active marketing. In addition, it can be expected that the low-priced cosmetic markets are guaranteed to obtain loyal customers through repurchasing and maintain long-term relationships by providing fashion followers with several promotional events.
