The Spartina anglica is recognized as a highly invasive plant and active eradication methods are required. In this study, we aimed to determine the physiologic activities of Spartina anglica extracts as a cosmetic ingredient. Antioxidant properties were investigated by different chemical methods including radical quenching (DPPH and ABTS), reducing power(FRAP) assay and aerial part of S. anglica(SAA) extract presented the strongest antioxidant activities. The significant cytotoxicity was not observed up to a concentration of 0.5 mg/mL in RAW264.7 cells and NHDF cells. The anti-inflammatory activity of S. anglica belowground(SAB) extract had strong effects on cell-based systems, including LPS-induced NO and cytokines(TNF-a and IL-6) production in RAW264.7 cells. Collagen synthesis and skin hydration gene expression of S. anglica extract showed the highest anti-wrinkle and moisturizing effect in NHDF cells. Results presented in this study tend to show that the ethanol extracts of S. anglica could be exploited as useful-bio-resource for bioactive substances in functional cosmetics.

In this study we applied the NAG obtained by the deacetylation of chitin extracted from the shells of crabs and shrimp as cosmetic ingredient. In order to compare NAG with GLC we identified the influence of cytotoxicity, anti-inflammatory, melanin biosynthesis formation inhibition on skin cell, and we measured the effects of the change of melanin and red spots. The results show that there was not any attentive cytotoxicity on the Raw 264.7 cell and B16F10 cell, and NO formation anti-inflammatory hindrance effect induced from Raw 264.7 by LPS was slight, and NAG suppressed the increase of melanin generation concentration-dependently after we induced the melanin generation with ${\alpha}$-MSH on B16F10 and measured the melanin biosynthesis inhibition. From this result, we identified the applicability of the cosmetics containing NAG as functional cosmetic for enhancing skin-lightening because when cream containing NAG was applied to skin the index of melanin red spots showed statistically meaningful changes.

Recently, our society has prominently raised the desire to well-being life since not only our economical situations are better than before, but environmental pollution become serious. In well-being trends, the natural or nature-related products are also issued on their usages as bio-/raw materials for our living industries, such as cosmetics, household goods, and so on. Especially, various materials which comes from medicinal plants has been discovered their physiological properties and validated their functions. Thus, they have been subjected to several processes, including extraction, isolation and concentration, and popularly introduced to cosmetic industry. In these reasons, a variety of cosmetic Products using natural materials has been developed, which are focused on whitening, wrinkle improvement, and anti-aging. In this report, we present a brief review of the function and classification of natural products interested in until now, and introduce the natural materials for cosmetics having physiological activities on skin, including Fructan, Acrea extract, Portulaca extract, Licorce extract, Dandelion extract, Ulmus extract, SC-glucan, Arbutin, and Sophora extract.

Sensory irritation is one of the important side effects of cosmetics and it is required to develop new products that are more tolerable to the consumers. There are lots of cosmetic ingredients known to induce sensory irritation such as lactic acid, glycolic acid, ethanol, preservatives, fragrances and menthol etc. It is also known that sensory irritation increases by change of pH as well as additional occlusive conditions. The aim of this study is to know various factors affecting sensory irritation due to preservatives (methylparaben, propylparaben, phenoxyethanol and chlorophenecin). We also wanted to investigate the effect of preservatives to sensory irritation according to change of formulations. Our results showed that sensory irritation increased with the conditions of increasing absorption such as packs. We have also found that sensory irritation increased synergistically when to apply two different preservatives together. For example, phenoxyethanol and chlorphenesin themselves have weak sensory irritation potentials, but we observed phenoxyethanol combined with chlorpenesin synergistically increase of sensory irritation potentials. In conclusion, formulation and combination of different preservatives should be considered to reduce the unwanted sensory irritation of preservatives.

This study was conducted to assessment organic compound and bioassay (density of inhabited animal, fluctuation of predominant fungi, and survival ratio of earthworm) for finding damage on red pepper by heavily amount application of sludges in soil, which was treated with 3 pharmaceutical byproducts and a cosmetic industry wastewater sludge as raw materials of compost, and for establishing estimation method. HEM contents in the soil treated with pharmaceutical byproducts sludge2 (PS2) and cosmetic sludge (CS) were 0.51, 1.10 mg/kg respectively. PAHs content of PS2 treatment in the soil was 3406.8 ug/kg on July 8. In abundance of soil faunas, the pharmaceutical byproducts sludge2 treatment was the most highest. The next was decreased in the order of pig manure (PM) and the cosmetic sludge treatment. However the other pharmaceutical sludge treatments were remarkably reduced populations of soil inhabited animals. In upland soil treated with organic sludges, the numbers of bacteria and fungi of the pharmaceutical sludge treatment were 736, 909 cfu/g and those of the cosmetic sludge treatment were 440, 236 cfu/g, respectively. The pharmaceutical sludge treatments and the cosmetic sludge treatment in identification of predominant bacteria were not any tendency to compare with non fertilizer and pig manure treatments, but they had diverse bacteria than NPK treatment. In microcosm tests, the survival of the tiger earthworm in five soil samples was hardly affected against the soil of PSI (20%) after three months treated in the upland But after six months, survival of PS1 was 80%. At present, raw material of compost was authorized by contents of organic matter, heavy metal (8 elements), and product processing according to 'The specified gist on possible materials of using after analysis and investigation among raw materials of compost', however, for preparing to change regulation of raw material of compost and for considering to possibility of application, this study was conducted to investigate toxic organic compound and bioassay methods using inhabited animal, fungi, and earthworm without current regulation.

In this study, we performed anti-oxidation, whitening, cell recovery and anti-inflammation effects with Alisma orientale to evaluate the cosmeceutical properties. Alisma orientate extract (30, 70, 100 % MeOH) exhibited a significant tree radical scavenging effect against 1,1-diphenyl-2-picryl hydrazine (DPPH) radical generation and showed tyrosinase inhibition effect in a dose dependent manner (over 0.5% concentration). In cell proliferation assay using human fibroblast, it didn't show any proliferation effect but showed safety from cytotoxicity under 0.05% concentration. For whitening assay, we evaluated the melanin synthesis rate using B16 melanocyte and it showed a significant inhibitory effect (up to 40% under 0.05% concentration). After major screening assay, we separate 3 fractions from Alisma orientate extract by MPLC and performed cell recovery assay, melanin synthesis inhibition assay and anti-inflammatory assay. The third fraction showed a cell recovery effect over 30% against radical damage and remarkable repression in melanin synthesis and COX-2 synthesis.
