In order to develop new anti-photoaging agents, we examined the antioxidative activity and the inhibition effect of matrix metalloproteinase-1 (MMP-1) on the extracts of a marine product, Zostera marina L., which is known for its potent activity. Three compounds (compounds 1, 2, and 3) were isolated from an ethyl acetate (EtOAc) soluble fraction of the product; they were identified as apigenin-7 -O-$\beta$-D-glucoside (1), chrysoeriol (2), and luteolin (3). These compounds were found to scavenge radicals and reactive oxygen species (ROS) and were measured to have $SC_{50}$/ values of 0.18 mM, 0.68 mM, and 0.01 mM against the 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical and 0.04 mM, 0.03 mM, and 0.01 mM against the superoxide radical in the xanthine/xanthine oxidase system, respectively. Compound 3 suppressed the expression of MMP-1 by up to 44％ at 4.0 $\mu$M and inhibited the production of interleukin 6 (IL-6), which is known as a cytokine that induces MMP-1 expression. From these results, compound 3 and the other compounds were determined to have antioxidative activity and to inhibit MMP-1 expression. Thus, the three compounds are expected to be useful for preventing the photoaging of skin.

In this study, the possibility of using marine life for cosmetic materials was assessed by establishing a fermentation process of seaweed, such as Ecklonia cava, Enteromorpha prolifera, Chondria crassicaulis, Eiseniabicyclis, Codium fragile, Seaweed furcata, Gloiopeltis tenax, Grateloupia elliptica, Undaria pinnatifida, and Saccharina japonica. Lactobacillus sakei isolated from Kimchi was used for effective fermentation and whole milk powder was used as an additive. 2.0 % of crushed seaweed and 1.0 % of whole milk powder were added and afterwards, 1.0 % Lactobacillus sakei was added after cooling to $40^{\circ}C$. After cooling and filtering the fermented product, butylene glycol, glycerine, and 1,2-hexandiol, which have the effect of a preservative, were added to mix and complete the final product. Among the ten kinds of seaweeds, the process was found to be highly effective in the fermentation of Ecklonia cava, Codium fragile, Undaria pinnatifida, and Saccharina japonica. The amount of fermentable substances in cosmetics was determined and the safety of the raw material was verified using the HET-CAM (The Hen's egg test-Chorioallantoic membrane) test.

The changes of cosmetic industry regulation in the leading countries, such as E.C., America, Japan, initiated our research to suggest the direction of our cosmetics regulation. These countries are strengthening the post-monitoring system for the safety and cosmetic industry development. We propose the agenda for the development of the industry; the extension of cosmetics range, deregulation of the advertisement, implementation of the ingredient labelling, introduction of the product expiring date. Ultimately. it is necessary to introduce and extend current CGMP to enhance the company responsibility and to reinforce the post-monitoring.

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.

Cosmetic industry is a typical industry for domestic demand and is closely connected with domestic demand growth. In 2006, domestic cosmetics market is showing high growth rate due to the recovery of domestic demand and the market reorganization of sales channels is proceeding rapidly due to the recent global economic slowdown, Due to the situation, many companies are launching low-priced brand shop. The purpose of this study was to clarify the impact of marketing strategy of cosmetic brand-shop on consumers' purchasing intention. As the result of analyses, it was found that product, place, promotion factors of cosmetic brand-shop affect brand image. Also only product factor affects corporate image, perceived quality. And using regression analysis between brand image, corporate image, perceived quality and customer behaviors. Brand image and perceived quality factors influence consumers purchasing intention. Brand image has a positive impact on corporate image. And corporate image affects the perceived quality.

Aloe is a popular and effective agent used to cosmetic ingredient. It could replace artificial pigment on make-up base product and it is highly probable that might be useful as ingredients of multi-functional color cosmetic. In this study, we made a makeup base containing aloe extract and tested the effectiveness, safety and stability. Contents of polyphenol and flavonoid from the aloe extract were measured. To determine the antimicrobial effect from the aloe we used the paper disc diffusion method. We assessed the safety of make-up base containing aloe to cultured macrophage RAW 264.7 cells by MTT assay. Polyphenol contents of aloe extract and flavonoid respectively were 48 mg/g and 10 mg/g, in the 10 % concentration aloe extract. In case of aloe make-up base, the clear zone against Stapylococcus epidermidis was 9~11 mm and Stapylococcus aureus was also 9~11 mm. Growth activity of macrophage RAW 264.7 cells was over 80% in all concentration of make-up base containing aloe and general make base product. In conclusion aloe extract may be able to substitute the synthetic pigments and considered to be uses for ingredients multi-functional color cosmetic's ingredient.

A rapid and efficient method for analyzing the nonionic surfactants and silicone polymers, which control the shape and characteristics of cosmetic products and give influence on product quality, has been developed using Matrix-Assisted Laser Desorption Ionization Time of Flight Mass Spectrometry (MALDI- TOF IMS). The MALDI-TOF/MS could easily and effectively determine the molecular weight distribution and monomer units of nonionic surfactants. As a result, creating a library of mass spectrum data of surfactants used in cosmetic products using MALDI-TOF/MS and analyzing surfactants extracted from the products may become a useful method for detailed structural characterization of the surfactants. Furthermore, the MALDI-TOF/MS analysis was effective in obtaining the spectrum of silicone polymers from which the molecular weight distribution could be determined. The repetition units and structural data could also be obtained through molecular mass peaks. Additionally, the monomer ratio and terminal groups as properties of silicone copolymers could be determined

A cosmetic manufacturing process requires a mold that is inevitable for mass production. Cosmetic containers are one of major factors affecting the customer's purchase decision. In addition, the manufacturing cost in cosmetic container comprises a large portion of the entire product cost. Therefore, a mold satisfying the economical feasibility, aesthetics and functionality is necessary. Among the cosmetic containers, square shape containers have a tendency of having a short shot defect product. The square shaped cosmetic containers are mostly produced as a side gate shape on the two-plate molds. On the other hand, there are two disadvantages, such as gate trace and post processing requirement. The overlap-gateproposed in this study has the characteristics of intaglio gate cutting and no need for post processing. The delivery system of the overlap gate was simulated and compared with the side gate via Moldflow. The improvement in flow, frozen rate, density, and Air trap was confirmed. Based on the simulation results, the mold and performed injection molding was fabricated. In this study, the possibility of the mass production of high aesthetic and functionality cosmetic containers was verified.

Bis-ethylhexyloxyphenolmethoxyphenyltrizine (BEMT) is one of the most widely used chemical UVA+UVB double absorbers in sunscreen products. But topical application of BEMT is restricted due to its defects in product. The purpose of this study is to adopt the sunscreen product of solid lipid nano-particles containing BEMT (BEMT-SLN). The particle diameters, the encapsulation efficiencies and the crystallization index (C.I.) are about 330nm, 93.3 % and the 4.3 %. As a result, in vitro penetration and release of BEMT were generally higher in O/W emulsion than the SLN formulation. However in vivo study, it was shown that the rate of release could be decreased by 80 % in the SLN formulation. The sun protection factor (SPF) of the SLN formulation increased by 100 % in the in vitro UV protection test. Therefore, SLN formulation potentiated the UV-blocking power of BEMT. This study suggest that SLN can be used for the encapsulation of BEMT.

Using the all-trans-retinol which is double-capsulated with matrix, we investigated its stability and the change of the epidermal thickness. The proprietary MDC comprise two steps of capsulation of retinol, i.e., primary microcapsulation with collagen and then secondary capsulation with gellan gum. We compared the activity of all-trans-retinol in various forms such as (1) simply in O/W, (2) in W/O emulsion, (3) in primary capsulted form in O/W emulsion, or (4) in MDC in O/W emulsion. After storage at 45$^{\circ}C$ for 4 weeks, retinol in MDC in O/W emulsion retained 92% of the activity compared to the standard material upon HPLC analysis, whereas the primary capsule gave 70%, the O/W emulsion form 47% and the W/O emulsion 78%. The retinol in MDC in O/W induced the siginificant increase in epidermal thickness compared to the vehicle.
