In this study, we investigated the effect of Petasites japonicus extract on the cytotoxicity and cytoprotective effects against cadmium for cosmetics use. We measured the protein expression of apoptosis regulatory factor (Bcl-2 and procaspase-3) after treatment of Petasites japonicus extract in the cadmium-induced keratinocyte. As a result, high cell viabilities above 98% were observed in the all treated concentrations except at $200{\mu}g/mL$ of Petasites japonicus extract in keratinocytes with cadmium-induced damages. In keratinocytes with cadmium-induced damages, Bcl-2 and procaspase-3 protein expression increased in the experimental group treated with Petasites japonicus extract. Also HaCaT cells resulted in cleavage of PARP protein at 12 h post-cadmium exposure. Western blot analysis and relative density of the bands suggested that pretreatment of cells with Petasites japonicus extract inhibited cadmium-mediated cleavage of PARP. These results suggest that Petasites japonicus extract can be used as the cosmetic ingredients for cytoprotective effect.

While the medical supplies have positive functions such as extending lifespan, recovering health, and preventing diseases, they also cause unexpected tragic consequences due to their side effects, and the magnitude of such damage inevitably increases due to the mechanism of mass production, mass distribution, and mass consumption of those medical supplies. Therefore, needless to say, the optimal way to prevent or reduce such damage is rather through medical supply manufacturers' producing non-defective products, or through the government's controlling production and sales of medical supplies with more aggressive exercise of regulatory authority on medical supply manufacturers, than through a remedy by a legal relief after using medical supplies. In this case, although the victim died due to the defect of the cold medicine, 'CONTAC 600', the drug company's responsibility to cover damages was not recognized because a defect could not be found in the then-manufacturing process. Thus, while pharmaceutical companies are gaining economic profits by producing and selling a medical supplies, if they do not take any remedy measures for the victims of their products' side effects, the victims have to use medical supplies under their own responsibility of taking a risk, and they have to accept the full damage of the potential consequence. Therefore, to remove such absurdity and contradiction, and to practically remedy the victim of medical supplies' side effects, the pharmaceutical side effects remedy project pending in the the Drugs, Cosmetics and Medical Instruments Lawneeds to be actively implemented.

In this study, we investigated the antioxidants activity by measuring electron donating ability and ABTS radical scavenging ability of the extracts from Rutaceae fruits (citron, grapefruit, lemon, mandarin orange, orange, trifoliate) to evaluate its use as a antioxidants in foods and cosmetics. Rutaceae fruits extract were separated in two parts of whole fruit (pulp, pulp fegment membrane, peel) and peel, dried, and then extracted with 70% ethanol. As a result of comparing the antioxidant effect at the concentration of 10,000 ㎍/mL, the electron donating ability was higher in the dried lemon peel extract (DLPE, 88.15%) and the dried citron whole fruit extract (DCWE, 80.44%), and the ABTS radical scavenging ability was highest in lemon peel and dried peel extract at 94.85% (FLPE) and 92.83% (DLPE). In conclusion, it was confirmed that lemon showed the highest antioxidant effect among the Rutaceae fruits(citron, grapefruit, lemon, mandarin orange, orange, trifoliate), and it was confirmed that the dried peel extract had a significant effect. Therefore it is considered that the dried lemon peel extract has the potential to be used as a natural antioxidant material in food and cosmetics.

The applicability of Brussels sprouts, which are widely cultivated in Jeju, as a functional biomaterial in the cosmetics and food industries is investigated. The active ingredients (total phenols and flavonoids, β-carotene, vitamin C, free sugar, minerals, glucosinolates, and isothiocyanates) and antioxidant activities of 70% ethanol extracts of Brussels sprouts and cabbage were analyzed. The total phenol, flavonoid, vitamin C, and β-carotene contents of Brussels sprouts were approximately 36%, 2.5 times, 2.3 times, and 65% higher than those of cabbage, respectively. The total free sugar content of Brussels sprouts was 58%-72% lower than that of cabbage. The K content was the highest among the other minerals, and there was little difference between the two samples. The Na content was approximately three times higher in cabbage than in Brussels sprouts. The total glucosinolate content of Brussels sprouts was 34.5 mol SE/g DW, twice that of cabbage. The sinigrin content of Brussels sprouts was thrice (10.06 μmol/g DW) that of cabbage. The isothiocyanate (sulforaphane, I3C) content in Brussels sprouts was double that of cabbage. The antioxidant activity of Brussels sprout extract was 2.5 to 2.8 times higher in 1,1-Diphenyl-2-picrylhydrazyl radical scavenging capacity and 3.3 to 3.6 times higher in 2,2'-Azino-bis(3-ethybenzothiazoline-6-sulfonic acid) radical scavenging capacity than those of cabbage extract. These are important basic data for the study of glucosinolates and isothiocyanates, which have anticancer activity, as well as antioxidant-related substances of Brussels sprout, which has high potential for use as a biomaterial in functional foods and cosmetics.

Up to now, better convenience and portability were important factors in the development of the cosmetics and achieved by immersing low viscosity makeup water-in-oil (W/O) emulsion into the impregnation material. Conventionally, polyurethane sponges having porous network structures and hard textures have been dominantly used. It has an advantage of easy to manufacture because of its good impregnation property due to its structural characteristics. However, it releases emulsion too much at first use, and shows unexpected dramatic decline during the period of usage. In this study, we studied on makeup W/O emulsion with various features and developed the new foaming sponge, which showed excellent formability and proper absorption and discharge ability of cosmetic composition through the combination of natural rubber (NR) and styrene butadiene rubber (SBR). This impregnation material is characterized by the softness of elasticity like a rubber, high elongation and uniform output. We confirmed that this material can be used to develop makeup products using various oils depending on polarity and controlling the viscosity of the makeup W/O emulsion. Thus, it is concluded that these results provide valuable information in developing new cosmetics impregnation materials.

In order to prevent microbial contamination and safely use cosmetics, it is essential to possess preservative power. In this study, the antifungal effect was confirmed by improving the preservative system of the aqueous dispersion formulation, which has a weak preservative power against fungi, and various preservative systems were established to strengthen the preservative power against fungi. Five kinds of raw materials (sodium anisate, p-anisic acid, caprylhydroxamic acid, o-cymen-5-ol, hydroxyacetophenone) that have a benzene ring structure having a hydroxyl group and exist as protonated form in cosmetic formulations expected to improve antifungal activity in cosmetics were selected, and the minimum growth inhibitory concentration of the raw materials was determined through MIC assay. It was confirmed that the preservative power against mold was improved through the preservative efficacy test of 4 types of water dispersion formulations (cream, lotion, toner, and sun cream) in which 4 types of raw materials showing antimicrobial activity against mold were added to the preservative system. When p-anisic acid was used, it was confirmed that the preservative activity against mold was strengthened without the effect of inhibiting the preservative power against bacteria and yeast in all four formulations.
