Liquid crystal known as a rheological barrier to coalescence of oil droplets, increases emulsion stability, water-holding capacity and promotes active material penetration to skin. Some investigation for its rheological characteristics have been reported but its relations to consumer perception have been rarely published. In this study, oil/water emulsion and oil/liquid crystal/water systems were manufactured using the same composition or Behenyltrimethylammonium chloride/Cetostearyl alcohol/Lanolin oil. and rheological properties or each system were investigated with Cone and Plate rheometer. The formation of liquid crystalline phase was observed with polarized microscope and Differential Scanning Calorimeter. Continuous shear experiment, creep, yield and water holding capacity were measured for oil/water and oil/liquid crystal/water systems. The results were compared with sensory evaluations. Oil/liquid crystal/water system showed higher,viscosity at the same shear rate. higher viscoelasticity and higher yield stress than oil/water system. These properties were expected to show good spreadability and excellent richness without waxiness in hair can: products of creme type. This expectation was consistent with the results of sensory experiments. Water-holding capacity was evaluated by measuring residual water of specimens at specific temperature and relative humidity. Oil/liquid crystal/water system was proved to have higher ability to hold water in comparison with oil/water system. The results indicated that oil/liquid crystal/water system was of benefit to rheological properties creme type hair care products.

A new method was developed to prepare microcapsules involving hydrophobic components. A totally new "silicone-resin-polypeptide" was used as the wall materials. The polypeptide was made by hydrolysis of collagen and silk protein and so on, and that was combined with silicone. This microcapsule was easily prepared from silicone-resin-polypeptide in water solution. The ratio of encapsulation in the microcapsule was not only high level as 90％, which had never been reached, but also the particle size could be controlled to obtain very small size (average particle size: 2${\mu}{\textrm}{m}$). Moreover, these microcapsules were resistant to high shearing forces and were stable over a long time period. This stable microcapsule was not crushed in pressure with finger spreading, so the core materials hardly touch the skin directly. Application in cosmetics by using microcapsule involving UV absorbents (2-ethylhexy1-4-methoxycinnamate (OMC) and 4-tert-butyl-4' -methoxydibenzoyl-methane (BMDBM)) was examined. It was possible to apply organic UV absorbents in water-rich formulations without any surfactant by using this microcapsule. This formulation demonstrated a good moisturizing and soft skin feel. Therefore, the microcapsule was applied to hair care products. As a result, the sunscreen hair lotion with microcapsule was able to prevent from damaging and decoloring of hair color by UV rays. As just, it was suggested that this microcapsules were be widely applied in cosmetics.cosmetics.

This study attempted to determine the effects of fermented green tea extracts on hair by using them in a perm. For this, hair is bleached, and then the fermented green tea extracts and water were supplied to the hair using a mist sprayer. Then the hair was permed, and hair damage was tested. Regarding hair moisture levels and wave formation, specifically, the morphological changes of hair were investigated with the Scanning Electron Microscope(SEM). The study results found the following. In terms of wave formation, the fermented green tea extract-based perm was much better than the general perm. In addition, hair bleaching was more serious in the latter. According to analysis on hair moisture using SEM, hair damage was more prevalent in the general perm as well. Therefore, it was confirmed that green tea extract-based perms cause less damage to the cuticle. In other words, the potential of fermented green tea extracts as a hair cosmetics material was discovered. Furthermore, it appears that the study results contribute to the development of low-irritating scalp and hair care products using the anti-inflammatory and antimicrobial properties of the fermented green tea extracts.

Caffeine is widely used in cosmetics and hair care products. Although its efficacy in stimulating hair growth has been confirmed in recent studies, its mechanism of action remains unelucidated. The present study aimed to determine the effects of caffeine on hair growth, with a focus on intracellular hair follicle activity. Experiments included in vitro and ex vivo tests, and a clinical study. Caffeine enhanced the cellular activity and potassium channel opening. It also promoted human hair follicle elongation. Immunohistochemical staining showed that the Ki-67 signal was significantly higher in cells treated with caffeine. These efficacies of caffeine were comprehensively demonstrated in clinical results, wherein caffeine-containing shampoo improved hair density after 24 weeks of testing. Collectively, the results of this study demonstrated that caffeine promoted hair growth and inhibited the progression of hair loss by enhancing intracellular activity of hair follicles.

Cosmetics are products that consumers use every day to maintain or improve the health of their skin and hair. Therefore, the expansion of the cosmetics market leads to the expansion of disputes over cosmetic damage. Along with constant social changes, new conflicts continue to arise. In order to resolve these disputes, various consumer dispute resolution organizations and methods are required. Therefore, Alternative Dispute Resolution (ADR), an alternative method that can provide a reasonable judgment on problems that occur during the manufacture and distribution of cosmetics with expert knowledge of the industry, is required. Korea resolves disputes between consumers and manufacturers caused by cosmetics through the ADR of the Korea Cosmetics Association and the Korea Consumer Agency. It handles disputes related to accidents caused by cosmetics, offers consultation on consumer complaints on cosmetics and provides information on accidents and safety related to cosmetics. It is not possible to completely eradicate disputes from cosmetic damages. Therefore, it is necessary to expand and efficiently operate the cosmetic ADR system for consumers. In this study, the current status of cosmetic damage disputes and damage relief and the role of the domestic ADR system were reviewed. Consumers should be easily relieved from damage caused by cosmetics. By accumulating important precedents with an efficient cosmetic damage dispute resolution system, disputes over cosmetic damage should be smoothly resolved.

In oriental medicine, the skin of the face and the body is the mirror of the viscera and bowels. Skin aging is measured according to the elasticity and glossiness of the skin, which is perceived as a matter of fluid-humor within the realms of oriental medicine. Fluid-humor refers to normal body fluid that makes the skin moist and supple and the hair bright and glossy. If the body is lacking fluid-humor, the hair and skin will be dry and coarse. 'The improvement of fluid-humor (nutrition)' is facilitated based on the oriental physiological change theory for middle-aged women. A new study is therefore necessary to develop oriental herbal cosmetics for young women in their 20s. As yet, there has been no study on the effect of herbal cosmetics formulated for middle-aged women and used by young women in their 20s. This study aims to investigate the effect of 'the improvement of fluid-humor' for the skin of young women in their 20s within the theory of oriental medicine. This kind of study is essential for oriental skin care and the development of diverse oriental herbal cosmetics. To determine the effect of oriental herbal cosmetics on young women in their 20s based on the theory of oriental medicine, which says that a shortage of fluid-humor causes skin aging, this study has examined the skin conditions of young women in their 20s and how satisfied they are with oriental herbal cosmetics through an objective equipment-based measurement and subjective questionnaire survey.
