Most consumers have noted hair damage following coloring treatments. Proper evaluation of hair bleaching products must be performed using quantitative assessments of hair damage, though they are difficult, because of the slight fluctuations in hair composition. In the present study, we utilized a sensitive evaluation method for hair damage and found that the amount of soluble protein fraction extracted from hair under a reducing condition, termed labile protein, dramatically increased after bleaching.(omitted)

In China, the phenomenon called 'Korean Wave' has boosted the interest in Korean pop culture, such as TV drama, music and films, and even in the general culture and society. As Korean singers, movie actors and talents become popular beyond acceptance of public culture, those who learn Korean, buy Korean products and visit Korea have emerged. Especially, most Chinese women have used Korean hair cosmetics and the interests in Korean hair cosmetics are increasing, since cosmetic companies entered China early due to Korean wave. Thus, the status of purchase of Korean hair cosmetics is growing day by day in China. In particular, since the environment is established to buy hair cosmetics easily in Myeong-dong which is one of the shopping tourism special districts, many Chinese tourists are crowded there. Based on such phenomenon, this study explored the differences in perceptions towards 'Korean Wave' among Chinese tourists who purchased Korean hair cosmetics in Myeong-dong, and analyzed the factors that largely determine the interest in Korean hair cosmetics and their purchase behavior. Therefore, this study is aimed at contributing to the development of hair cosmetics products and the market amid Korean Wave. As the research methods, 100 answered questionnaires were collected with target of Chinese tourists at 20s and 40s who purchased Korean hair cosmetics in Myeong-dong once 120 questionnaires were distributed. In-depth analysis was conducted and final research data were used. It was confirmed that Korean fever positively affected the Chinese tourists' purchase behavior and satisfaction of hair cosmetics, and the interests in Korean hair cosmetics at 20s were higher than at 40s. People at 20s had higher awareness, satisfaction and intention of repurchase of hair cosmetics compared rather than people at 40s. The research confirmed that Chinese tourists are very interested in Korean hair cosmetics as the pop music craze has led to the general Korean Wave, and differences in such perceptions have led to significant differences in the product purchase behavior.

본 연구에서는 국내 시장에서 판매되는 다크닝 샴푸 5종에 대한 성분 분석을 실시하고, 그 결과를 바탕으로 해당 제품들의 유효 성분과 안전성에 대해 평가하였다. GC-MS 분석을 통해 각 샴푸의 주요 성분을 확인한 결과, 제조사가 표기한 전성분 목록과 일부 차이가 있는 화합물들이 검출되었다. 이는 GC-MS 분석의 한계와 특정 화합물의 휘발성 여부에 따른 것으로 해석된다. 이러한 분석을 바탕으로, 모발의 색상 변화에 기여할 가능성이 있는 화합물을 조사하였다. 그러나 이러한 화합물들이 모발 다크닝 과정 자체에 직접적으로 관련된 역할을 하는 성분이라고 단정지을 수는 없었다. 다만 헤어 케어 제품의 성능을 향상시키고 모발에 대한 일부 추가적인 이점을 제공하거나 제품의 질감, 안정성 또는 보존 등의 특성을 향상시키는 역할을 하는 것으로 추정할 수 있었다. 또한 GC-MS 성분 분석 결과, 확인된 성분 중 안전성이 우려되는 화합물에 대한 조사를 통해 화장품 원료로 사용될 경우 주의가 필요한 몇 가지 화합물에 대한 정보를 제시하였다.

During cosmetic treatments, SURFACTANTS penetrate into KERATINOUS TISSUES (hair, skin and nails). Whereas some of these surfactant molecules migrate to the vital tissues, a considerable fraction remains bound to the keratin. The extent of binding depends both on the nature of the head group and the length of the hydrophobic tail of the detergent molecules. In addition to entering the amorphous region of the keratin, some of the detergents also penetrate into the crystalline microfibrils and change their structures affecting their tensile properties. Owing to an uneven distribution of detergent molecules in the tissues, an anisotropy of the elastic moduli will occur, resulting in considerable internal stresses which, in rum, might lead to a deterioration of hair, skin and nails. The chemical behavior of keratins is also influenced by the presence of absorbed detergent in their structures. Depending on the detergents and the conditions, these effects can be either protective or detrimental. The deposition of detergent molecules into keratin can be enhanced or diminished by the inclusion of appropriate ingredients into the product formulae.

A novel simple method to detect vitamins in cosmetic products by gas chromatography-mass spectrometry(GC-MS) has been developed. Three vitamins(panthenol, cholecalciferol and tocopherol) were used for this study. Vitamins were prepared by dissolving in tetrahydrofuran(THF), and silylated with bis-trimethylsilyltrifluoroacetamide-trichloromethylsilane(BSTFA). Silated vitamins were separated on a fuses-silica capillary column coated with DB-5. The identification of each vitamin was accomplished by retention time and mass spectrum library search with a computer, and the quantitation was made in the selected-ion monitoring(SIM) mode of GC-MS. SIM mode had given sensitivity to determine 50pg of panthenol, 285pg of cholecalciferol and 130pg of tocopherol. Linearity was maintained over the range 0.005-0.20% for each vitamin. Each cosmetic product(i.e. hair tonic and lotion) was found to contain amounts of the vitamins. This method was sensitive and gave 77.5-99.9% recovery of each vitamin from these cosmetic products. From these results, we concluded that silylation with BSTFA followed by GC-MS analysis allows the simple, covenient and exact determination of panthenol, cholecalciferol and tocopherol.

There have been many kinds of hair styling sprays with various setting effects. Consumers have used strong setting effect hair sprays to get a long lasting hold. In recent years, however, more and more consumers have come to prefer a "soft ＆ natural" touch feeling, keeping the same long lasting hold. Nonetheless, the existing approaches to this feature could not respond to the consumers′ needs, since products lose the hold strength if the soft feeling is pursued, and vice versa. We have researched and developed a new products to attain a compatible feature with both long lasting hold and natural feeling. Then, we have developed a new multifunctional hair styling material "Poly Amino Acid Derivative (PAAD)." We have focused on the PAAD′s feature that highly diffuses onto a hair and makes thin and even layer on a hair, and have made trials and errors to improve holding strength. "P AAD" excellently makes hair memorize its curl shape which is as the same effect as existing ordinary acrylic resin. Further more, it leaves a soft and natural touch feeling on the hair. We have accomplished a new Poly Amino Acid Derivative with ambivalent features, "soft ＆ natural finish" and "long lasting hold ", and now we report about it.
