This study is focusing on typicalized character make-up of TV Drama characters. The purpose of this study is to analyze the interconnections of its images and impressiology concretely, and then reflect on an application approach of impressiology. The aim of make-up lies in not only helping actors to visualize their own external qualities, appropriate the quality of a play, but also audience and spectators to be immersed in the concrete fact of i character person. Impressiology will be a data to give the understanding and sympathy of make-up work. I would like to utilize character make-up based on impressiology for creative and effective make-up techniques, and make it a typicalized character. Also I will examine the horizon of a new make-up technique through character development according to the demandes of the times. As a result of this study, we find that expression method of characteristic character generalized representatively is the common quality of impressiologistc image. Also we see that such a impressioiogistic image is useful for the fundamental basis of character expression method.

In case of lipsticks, observer's subjective sensitivity has been the main index to estimate gloss and gloss-lasting capability. The glossmeter has been applied to measure the gloss of make-up cosmetics like nail enamel, however is not effective for lipstick because of uneven sampling. Also gloss-lasting capability couldn't have been measured. In this study, we optimized measurement methods of gloss and gloss-lasting capability of lipsticks, which are highly correlated to subjective sensory tests. We set up the standard methods of gloss measurement by changing application conditions, for example, materials, sizes and application number of times and so on. And we introduced optimizing measurement system, in which shaking speed and temperature were controlled to measure gloss-lasting capability. Applying our methods, the gloss values were very close to the results of sensory tests, and we could express the gloss and gloss-lasting capability of lipsticks numerically Repeatability and reproducibility of our methods were certified by six-sigma statistical tool.

Generally pigment differs from dye stuff because it cannot be melted in water but also because it is stable physically and chemically. In this study you will discover the function, properties and effects of Micai-TiO$_2$-SiO$_2$pigment as abase material pigment. But until now used Mica of the base material is about 7-l5${\mu}{\textrm}{m}$ with an average diameters of 15${\mu}{\textrm}{m}$. A new characteristic superficial pigment was obtained from covering the TiO$_2$ and SiO$_2$ with the adsorption result of isoelectric point of a Mica flake, TiO$_2$ and SiO$_2$In the composition reaction study of adsorption was done as well as the physical characteristics of the superficial texture of the obtained material. L,a,b of color change as oil was absorbed, optical nature and change of reflection according to direct and diffused reflection. In the composition of Mica slurry the best result obtained was in a solution with pH 2.0 to 2.3. Following this result, we can come to the idea that electrical attraction was done during the change of electrical charge of the Mica and TiO$_2$ deposit. Also this pigment shows a big scale between the direct reflection and diffused reflection light. Using this characteristic in cosmetic, it was obtained a natural but a contrast between light and shadow making possible a sculptured make-up. Color change due to oil adsorption was insignificant which improved the last of make up.

A bacterial strain No. HB-5, which was capable of producing a pretense in the culture conditions, was isolated from the soil . The pretense was purified from cultural filtrate of Bacillus sp. HB-5 by membrane ultrafiltration and DEAE- cellulose chromatography, gel filtration on Sephadex G-100. The molecular weight was estimated to be 60k4a. The optimal pH and temperature for the activity of the purified pretense pH were 11 and 5$0^{\circ}C$ , respectively. The enzyme was stable within a pH range 8-12 and up to 6$0^{\circ}C$ . The enzyme activity was highly inhibited by PMSF at 1mM. The proteolytic actions of pretense and papain on human epidermis keratins which are major protein impurities on the skin, were compared. The bacterial pretense degraded more effectively than papain. Product containing 2% protease exhibited 21% increase on the skin coloration index. These results suggest that cosmetic product containing pretense produced by Bacillus sp. HB-5 could remove the adherent keratin layer and then make a softer skin.

Dry skin is caused mainly by the perturbation of stratum corneum lipids which affected by ageing, change of season, excess use of surfactant and the effect of disease like atopic dermatitis and psoriasis. Intercellular lipid structures in stratum corneum are responsible for the barrier function of mammalian skin. The major lipd classes that can be extracted from stratum corneum are ceramides, cholesterol and fatty acid, which make up approximately 50, 25, 10 percent of the stratum corneum lipid mass, respectively. Small amount of cholesterol sulfate, phospholipids, glycosylceramide and cholesterol esters are also present. Recent studies have shown that application of one or two these lipids to the perturbed skin delays barrier recovery; only equimolar mixtures allow normal recovery. We observed that barrier recovery rate was improved in hairless mouse by topical application of single neutral lipids (ceramide, free fatty acid, cholesterol) and lipid mixtures. Whereas the application of single lipid didn’t allows a significant enhancement comparing with normal barrier repair, the equimolar mixtures of 3 components(including synthetic pseudoceramide PC104) improved barrier repair, as assessed by the transepidermal water loss. At clinical study to the volunteers aged over sixty, skin dryness recuperated by the increase of moisture(capacitance) and the reduction of scaling. Utilization of physiologic lipid mixture containing natural ceramides or synthetic pseudoceramide could lead to new forms of topical therapy for the dryness and dermatoses(e.g., psoriasis, atopic dermatitis and irritant dermatitis).

In this paper, facial feature areas in user picture are created by facial feature points extracted by ASM(Active Shape Model). In a existing virtual make-up application, users manually select a few features that are exactly. Users are uncomfortable with this method. We propose a virtual makeup application using ASM that does not require user input. In order to express a natural makeup, the modified alpha blendings for each cosmetic are used to blend skin color with cosmetic color. The Virtual makeup application was implemented to apply Foundation, Blush, Lip Stick, Lip Liner, Eye Pencil, Eye Liner and Eye Shadow.

It has been used that fluorinated compounds could be applied to Make-up products. It is that fluorinated compounds are hydrophobicity, lipophobicity and homophobicity. These fluorinated compounds are reported to form a highly protective and effective film against most aggressive chemical and physical agents. In this study we maed a success to formulate the new type of lipstic using perfluoropolymethylisopropylether with low molecular weight which is long wearing and comfortable to use. This PPIE was adsorbed more than 90% in this experiment and formed the well-balanced gel networks even if the selected PPIE is 100% volatile at room temperature. On the basis of the adsorption of PPIE, we developed the new type lipstick, which was highly-lip feeling and had long wearing and non coloration. And these characteristics were verified by actual consumer test.

Nanoparticles are substances that are smaller in size and smaller than cells that make up the skin. Therefore, they are very suitable as mediators for transmitting drugs or genes across cell membranes, and also deliver specific ingredients into the skin.In this study, nanoparticles were extracted from mugwort and particles of around 100 nm were obtained through dynamic light scattering (DLS), and the results of concentration-dependent enhancement of cell viability in fibroblasts were obtained through MTT assay. In addition, it was confirmed that the COL1A1 mRNA expression level was increased and the IL-6 mRNA expression level was decreased through the quantitative real-time PCR analysis method. Moreover, as these nanoparticles were confirmed to be stable, they can be applied not only to cell experiments but also to cosmetic formulations. While the demand for plant-derived ingredients continues to increase, excluding chemical ingredients from the recent cosmetics industry trend, there is a limitation in that there are few research results suggesting the application field of plant-derived nanoparticles. Therefore, in order to overcome the limitations of the cosmetic industry at the present time, the results obtained in this study present nanoparticles derived from Artemisia princeps (NDAP) as a highly functional cosmetic material.

The new stick make-up product was studied by using a gel, which is a viscous complex formed with clay minerals, vitamins A and E and fluorinated liquid polymer with a 1500 molecular weight. The gel cannot be obtained with any random combination of clay minerals and the ingredients described above. It takes the sequential manufacturing method as follows to get this kind of gel. Firstly, clay minerals and liquid polymers have to be pre-mixed in order to saturate the liquid polymers with the clay minerals. Then the on-processed gel has to be finely crystallized. The clay minerals, which are the core elements for this gel, were used as a function of Binder & Buffer and liquid polymer was mixed together for the deterioration of the surface tension of each component and to form a functional film in the gel. This liquid polymer was combined with clay minerals because it is not miscible with most oils and solvents. Waxes have a function of keeping a solid status in the stick. We reduced the usage of waxes by putting clay minerals as buffer in the proportion of 0.5:1 with oil phase. Ceramide takes care of the skin when used regularly and maintains the skin's moisture. Vitamins A and E contribute to preventing skin aging by the activation of skin cells. We could get the stable viscous gel, which has about 80% oil phase using clay minerals and liquid polymer. The crystalline structures of gel were surface-chemically-analyzed using SEM and Image Analyzer and were thermodynamically analyzed using DSC. Surface tension test and softness were done by Rheometer. In the end, these characteristics were verified by consumer panel tests in Seoul, Daegeon and Pusan in Korea and Hokkaido, Osaka and Miyazaki in Japan with correlation to the climate.
