Synopsis-The difficulties of immunological nonienclature are discussed, the term ALLERGY defined and the various types of HYPERSENSITIVITY reactions are listed and characterized. Evidence for the association of Type I and Type 11 hypersensitivity reactions with COSMETICS is discussed. A table of cosmetic ingredients which have been implicated as SENSITIZERS are given. PREDICTIVE PATCH TESTS for contact sensitizers on GUINEA-PIGS and man are evaluated. The difficulties of testing for ALLERGENS likely to produce Type I hypersensitivity are discussed. IN VITRO tests for sensitizers are mentioned. The failure of all standard tests in the detection of weak sensitizers is emphasized.asized.

본 연구는 한방화장품의 원료로써 사용이 되는 약용식물들의 부위별 및 추출용매에 따른 추출물의 효능의 차이를 기술하였다. 기존의 단일성분 분석법보다 실제로 성분의 복합체인 추출물에 대하여 항산화와 UV흡수 관련 효능효과 시험법을 적용하였다. 약효를 가지는 약용식물들을 추출할 때 고려해야 할 조건이 있다. 같은 약용식물이라도 채취시기, 채취장소, 채취부위와 같은 채취조건들과 용매의 종류, 추출시간, 추출온도와 같은 추출조건들을 고려하여야 한다. 조건 중에서 추출용매와 채집부위는 효과에 있어서 매우 중요한 요인이다. 약용식물에 대한 관심이 증가하면서 여러 가지의 채취조건과 추출조건을 연구하여 한방원료의 개발에 있어 좀더 다양한 적용이 요청되고 있다. 본 연구에서는 약용과 식용으로 널리 사용되는 식물(Terminalia chebula, Syzygium aromaticum, Paeonia lactiflora, Morus alba, Scutellaria baicalensis)을 선정하여 추출용매와 채집부위를 변경시킴으로써 용매와 부위에 따른 효능의 차이를 확인하였다. 이 결과로 추출시 적당한 조건을 선택한다면 사용되는 약용식물의 양을 줄이거나 좀더 효과적인 결과를 얻을 수 있다.

Cosmetic mask is one of the traditional cosmetic product and is used to keep skin healthy and beautiful through moisturizing effect, cleansing effect and acceleration effect on microcirculation. There are several types of cosmetic mask such as peel-off type, tissue-off type, wash-off type and cotton sheet type immersed in cosmetic water. It is important for cosmetic formulators to develop an adequate type of cosmetic mask that meets the needs of the target consumers because each type of cosmetic mask has benefits and problems in its usage and efficacy. Polyvinyl alcohol (PVA) is widely used as an active ingredient of peel-off type cosmetic mask and the physical property of the PVA film changes with the usage of other ingredients. We studied the change of physical properties of the film containing PVA by formulating peel-off type cosmetic mask with the variation of humectants. Methylguceth-20 and glycereth-26 reduce the interaction between skin surface and PVA film without serious weakening of tensile strength and they can alleviate irritation. Glycerin, urea and betaine help PVA film soften and they also have excellent efficacy as humectants.

본 연구에서는 감초성분인 glycyrrhizin, liquiritin, liquiritigenin, isoliquiritigenin의 항균활성을 측정하고, 원산지별 감초 추출물에서 항균활성 성분인 isoliquiritigenin과 liquiritigenin을 정량하여 비교평가하였다. 또한 challenge test를 통하여 가장 뛰어난 항균활성을 나타낸 isoliquiritigenin과 합성 방부제인 메틸 파라벤과의 방부력을 비교하였다. 감초 성분의 항균활성을 disc diffusion assay를 통해 측정한 결과, Liquiritigenin과 isoliquiritigenin이 B. subtilis, P. acnes, E. coli, P. aeruginosa에 대해 저해활성을 보였다. 특히 감초성분 중 큰 항균활성을 나타낸 isoliquiritigenin과 합성 방부제로 사용되는 메틸 파라벤과 프로필 파라벤의 최소저해농도를 비교한 결과 isoliquiritigenin이 강력한 항균활성을 나타내는 것을 확인하였다. HPLC를 통해 원산지별 감초 추출물 isoliquiritigenin과 liquiritigenin을 정량한 결과, 이들의 함량은 한국산 감초가 중국산 감초와 우즈베키스탄산 감초보다 높은 것을 확인하였다. 이를 통해 한국산 감초가 우수한 항균력을 나타내는데 isoliquiritigenin, liquiritigenin 함량이 영향을 미치는 것으로 판단된다. Isoliquiritigenin의 B. subtilis, P. acnes, E. coli, P. aeruginosa에 대한 challenge test를 통해 메틸 파라벤 보다 isoliquiritigenin이 뛰어난 방부력을 나타냄을 확인하였다. 이상의 본 연구 결과로부터 감초 성분의 항균활성을 확인하였고, 원산지별 감초(한국, 중국, 우즈베키스탄) 중 한국 감초가 우수한 항균력을 나타내는데 isoliquiritigenin과 liquiritigenin 함량이 영향을 미치는 것으로 사료된다. 또한 감초 성분 중 가장 우수한 항균활성을 나타낸 isoliquiritigenin은 파라벤류를 대체 할 수 있는 천연 보존제로써 이용 가능성이 있다고 판단된다.

Objectives : The purpose of this research was total polyphenol contents, anti-oxidant activities, anti-inflammatory activities and anti-wrinkle activities of Ulleung islands plants for application as a cosmeceutical ingredients Methods : We were experimented total polyphenol contents, anti-oxidant activities, anti-inflammatory activity and anti-wrinkle activities. Results : In the physiological activities, most Ulleung islands plants is showed the highest anti-oxidant, anti-inflammatory activity in ABTS+ radical cation scavenging activity, hydrogen peroxide($H_2O_2$) scavenging activity, nitric oxide scavenging activity. All experiment of the water and ethanol extract from the Ulleung islands plants ingredients were gradually increased as well. Conclusions : These results suggest that extracts from Ulleung islands plants can be used in natural ingredient in food or cosmetic industry.

In Korea-U.S.A. FTA Negotiation, U.S.A. request to eliminate barriers of tariffs and non-tariff in trade of cosmetics. Korea applies tariffs of 8% on most cosmetics and personal care products. There are some non-tariffs barriers in cosmetics trade between Korea and U.S.A., for example, transparency on restriction and regulatory, cosmeceuticals, import clearance review, quality control testing, ingredient labelling. Tariffs of 8% on most cosmetics should be eliminated, a proviso of complementary measures on sanitation of Korean people about imported cosmetics. This is a meaning of reformation of prior management(tariffs) by strong ex post management in cosmetics trade. It is important that Korea should construct system of ex post management, for instance, construction of data base on manufacturer, importer, bland name of cosmetics and all ingredients of cosmetics. This is concerned with labelling of cosmetics and cosmeceutical and publication of Korean edition of INCI(International Nomenclature of Cosmetic Ingredient).

Certain types of anti-inflammatory components and whitening components were in practical use as the active ingredients of quasi drugs expected to display their pharmacological actions. However, only twenty years at most have past since the introduction of cosmetics that not only physically change the condition of the surface of the skin, but also promote skin homeostasis from by acting on the physiological mechanisms of the skin. Since then, much effort hasa been made to find new active ingredients suitable for full-scale development, and the term "cosmeceutical" has often been coined to describe cosmetics containing pharmacologically active components. In this report, the prospects of cosmeceuticals will be discussed on the basis of a review of the history of the development of current skin-care products.

Heavy metal ingredients of eyeliner product could cause side effect ranging from simple irritation, keratitis, corneal epithelium inflammation, eyelid dermatitis and dry eye symptoms have been reported. This study was conducted in order to prepare fundamental data for acceptable quality level heavy metal ingredients in the domestic and foreign cosmetic brand eyeliner products and to assess theirs the heavy metal concentrations. We measured the concentration of 5 heavy metals in 10 eyeliner products using ICP/MS-LC. According to the results, the average metal concentrations were as follows.; In case of domestic eyeliner products, 289.4 ppm for aluminium(Al), 304 ppm for manganese(Mn), 44 ppm for nickel(Ni), 0.58 ppm for arsenic(As) and 0.35 ppm for lead(Pb). In case of Foreign eyeliner products, 11337.8 ppm for aluminium(Al), 1678.8 ppm for manganese(Mn), 74.2 ppm for nickel(Ni), 1 ppm for arsenic(As) and 0.8 ppm for lead(Pb). Foreign products contained higher amounts of the two elements(Pb, As) compared to domestic ones. Also, greater concentrations of arsenic(As) were detected from waterproof products than non-waterproof ones. In conclusion, for safety reasons we suggested the amounts of heavy metals from the domestic and foreign eyeliner products. This finding will be helpful to provide the fundamental data which is standard of toxicological heavy metals acceptable on eyeliner products.
