  • This study examined the ultraviolet-A blocking effect and antioxidant activity of Gracilariopsis chorda extract for use as sunscreen agents in cosmetics. The maximum absorbance at ultra violet-A320-330 and transmissivity was 20-80%. The 1,1-diphenyl-2-picrylhydrazyl (DPPH)radical scavenging activity of Gracilariopsis chorda extract was 68?96% and increased with the sample concentration. This indicates that Gracilariopsis chorda extract is a promising natural compound that could be useful as a sunscreen.

  • This research was carried out to investigate the moisturizing effects of Agarum cribrosum extract on normal human epidermal keratinocytes (NHEKs). Moisturizing effects of A. cribrosum extract on NHEKs were measured by quantitative realtime RT-PCR to verify the gene expressions related to skin hydration, hyaluronic acid (HA)-ELISA to detect HA production, and cell viability assays. A. cribrosum extract increased the mRNA levels of the AQP3 and HAS2 genes and HA production in NHEKs. On the other hand, A. cribrosum extract decreased the mRNA level of the KRT1 and KRT10 genes known as differentiated keratinocyte marker in NHEKs. This research showed the moisturizing effects of A. cribrosum extract. The results indicate that A. cribrosum extract can be a potent functional ingredient for skin hydration and anti-aging products. Further study is warranted regarding the use of A. cribrosum extract to develop not only cosmetics but also food and medicine.

  • This article focused on all that matter that effect brand switching. For that we selected college students especially live inner city and outskirts of Seoul. also this empirical study limits sample to female only. The reason is this study will only concentrate on the usage of cosmetics that for basic skin care products. we presume the brand switching factors would be advertising satisfaction of product, promotion, anecdotal effect of gods, corporate image and brand image. The results shows our study frame was apparently accurate. we expect the finding about brand switching on this article gives some weighted clues to establish brand switching marketing strategies. Because our study deals with new tendencies of the newest generation that use basic skin care products.

  • Natural colorants are regarded as substitutes for synthetic colorants in the fields of fiber dyeing, hair dyeing, cosmetic, and food industries. The use of natural colorants has been increased in view of global environment and sustainability. However, scientific approach to the production is required because the supply of natural colorants depends on the climate, soil, and cultivation methods. This brief review contains the advances in science and technology related to natural colorants including characterization, analysis, CIEL*a*b* and Munsell color systems, and future prospects. For the characterization and the analysis of natural colorants, chromatography, some spectroscopic techniques (UV-Vis, FT-IR, NMR), mass spectrometry, and X-ray diffraction are generally used.

  • Background: Benzalkonium chloride (BKC) has been extensively used as a preservative in industrial products and in hygiene, medical, and cosmetic applications. Humidifier disinfectant (HD) products containing BKC have been used in South Korea. Objectives: This study was aimed to review types of products containing BKC, to summarize the regulations in the US, EU, Japan, and South Korea, and to review the health effects associated with the use of HD. Methods: We reviewed and summarized documents which were searched through PubMed and Google Scholar with the key words: BKC and asthma/contact dermatitis, humidifier disinfectant-associated lung injury (HDLI), and more. Results: Regulations in most countries including South Korea do not allow its use as disinfectants in spray-type of products for medicine, cosmetics, and household products. Two types of HD containing BKC (800~1,270 ppm) were marketed in South Korea from 1996~2003. Health effects reported from people who used products containing BKC were allergic contact dermatitis, erythema, and respiratory disease, including asthma. Two people who responded as HD users containing BKC only were confirmed to have developed asthma. HD-associated lung injury (HDLI) was reported by consumers who used both HD containing polyhexamethylene guanidine (PHMG) and HD containing BKC. Conclusions: In conclusion, the use of BKC as a biocide has to be controlled considering the route and pattern of exposure. Products containing BKC as preservatives were reviewed with exposure routes and sites in the human body such as skin, eyes, and the respiratory tract. HD containing BKC was clinically evaluated to be associated with asthma.
