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.

This study was to evaluate the efficiency of different solvent systems to extract active ingredients from different parts of medicinal plants used as oriental medicinal herb in the cosmetic industry. We tested efficacies related to the antioxidative effects and UV absorption of herbal extracts as complex of active ingredients, not each single ingredient. When extracting medicinal plant which is used effective medicine, we should consider the collecting conditions like collecting time, place, part and extracting conditions like solvent, temperature, time, and etc. Among them, extraction solvent and collecting part are very important factors for the efficacy. As increased interest in medicinal plants, more intensive studies on collecting conditions and extracting processes were needed for the developments in the herbal ingredient industry. We evaluated the efficiency of different solvent systems to extract active ingredients from different parts of plants (Terminalia chebula, Syzygium aromaticum, Paeonia lactiflora, Morus alba, Scutellaria baicalensis) widely used as medicine and food. As results, we found that proper condition can make better data and decrease the required quantity.

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.

The present study was aimed at investigating the antimicrobial activities of licorice's active ingredients. Four samples of licorice ingredients (glycyrrhizin, liquiritin, liquiritigenin, and isoliquiritigenin) were evaluated for their antimicrobial activities against six skin microorganisms. The bioassay applied for determining the antimicrobial effects employed a disc diffusion assay, the minimum inhibitory concentration, and the challenge test. The ingredients showed antibacterial activities. Especially, isoliquiritigenin has significant antimicrobial activities against two Gram-positive (Bacillus subtilis, Propionobacterium acnes) and two Gramnegative (Escherichia coli, Pseudomonas aeruginosa) bacteria. These samples had much higher antimicrobial activities than synthetic preservatives. Our results reveal that liquiritigenin and isoliquiritigenin could be useful compounds for the development of antibacterial agents for the preservation of cosmetics and foods. The two flavonoids, liquiritigenin and isoliquiritigenin, sourced from Korea, China, Uzbekistan, were quantified using HPLC. The results demonstrated that Korean licorice has two flavonoids (liquiritigenin, isoliquiritigenin) in much higher quantities than was observed in the licorice obtained from the two other countries. Thus, isoliquiritigenin and Korean licorice extract represent new candidates for antimicrobial agents.

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.
