Abstract:
PURPOSE: A method for generating a heat protection factor is provided to generate a heat protection factor, thereby objectively evaluating an effect of a cosmetic product including heat protection materials. CONSTITUTION: A first area spread with heat protection materials and a second area which is no the heat protection materials are heated respectively(S1). Saturation temperature of the first area is measured(S3). The saturation temperature of the second area is measured. An energy corresponding to heat heated in the first area is divided into the saturation temperature of the first area for calculating a first energy(S5). The energy corresponding to heat heated in the second area is divided into the saturation temperature of the second area for calculating a second energy. A heat protection factor of the heat protection materials is calculated by dividing the first energy into the second energy(S6). [Reference numerals] (AA) Start; (BB) End; (S1) Applying heat in a first area where a heat protection material is spread and a second area where no heat protection material is spread; (S2) Periodically measuring the temperature of the first area and the second area; (S3) Determining whether the temperature of the first area and the second area reaches a saturation temperature; (S4) Calculating the minimum heating amount of the first area and the second area; (S5) Calculating first and second energy by using the minimum heating amount of the first area and the second area and the saturation temperature; (S6) Calculating a heat protection factor of a heat protection material by using the first and second energy
Abstract:
PURPOSE: A composition of external use skin formulation for anti-aging and moisturizing is provided to suppress MMP(matrix metalloprotease) increase. CONSTITUTION: A composition of external use skin formulation contains 0.001-10 weight% of 11,14,17-Eicosatrienoic acid(ETA) as an active ingredient. ETA is contained in oil phase. The composition is used for preventing aging through reduction of collagenase expression. The composition is also used for skin moisturizing by suppressing skin barrier damage.

Abstract:
A skin external composition comprising a cathepsin G inhibitor is provided to prevent an adhesion protein from being degraded by intrinsic aging and photo-aging, reduce the production of metalloproteinase and inhibit the activity of metalloproteinase, thereby being more potent anti-aging substance than existing anti-aging substances. A method for screening anti-aging materials is provided to develop the anti-aging materials which effectively inhibit the quantitative and qualitative increase of metalloproteinase, resulting from the degradation of an adhesion protein by cathepsin G in skin cells without direct UV irradiation. A skin external composition for preventing skin aging comprises 0.01-10 wt% a cathepsin G inhibitor as an effective ingredient, wherein the cathepsin G inhibitor is at least one selected from the group consisting of compounds represented by formulae(1) to (4). The composition is formulated into skin lotion, astringent lotion, milk lotion, nourishing cream, essence, massage cream, eye cream, pack, body lotion, body cream, body oil or body essence. A method for screening an anti-aging material comprises the steps of: (a) adding an anti-aging candidate material to a substrate in the presence of cathepsin G enzyme; and (b) measuring the inhibition of activity of the cathepsin G enzyme. Further, the measure of the inhibition of activity of the cathepsin G enzyme is performed by measuring a concentration of a produced metalloprotease.
Abstract:
A skin external composition for skin-whitening containing manassantin B is provided to inhibit mobility of melanin by inhibiting binding of melanophilin as a carrier of melanosome in a melanocyte with myosin 5a, thereby forming melanosome aggregation and whitening the skin. A skin external composition for skin-whitening contains 0.001-10% of manassantin B which is extracted from Saururus chinensis Baill by extracting Saururus chinensis Baill with water or organic solvent selected from ethanol, methanol, butanol, ether, ethylacetate, chloroform and methylene chloride, filtering the extract, concentrating the filtered solution under reduced pressure, extracting the concentrate with methylene chloride and concentrating the extract under reduced pressure, and is formulated as solution, suspension, emulsion, paste, gel, cream, lotion, powder, soap, surfactant-containing cleansing, oil, powder foundation, emulsion foundation, wax foundation or spray.
Abstract:
Provided are a gallic acid adamantamine amide compound which inhibits the generation of melanin, a method for preparing the compound, and a cosmetic composition containing the compound. The gallic acid adamantamine amide compound is represented by the formula 1. The method comprises the steps of dissolving gallic acid in a solvent, adding a catalyst and a base to the solution drop by drop, and reacting it with acetic anhydride to prepare the acetylated compound represented by the formula II (See the reaction scheme 1); dissolving the acetylated compound in a solvent and adding a base, ethyl chloroformate and adamantamine to prepare the amide compound represented by the formula III; and reacting the obtained amide compound with a base to hydrolyze it, thereby preparing the gallic acid adamantamine amide compound represented by the formula 1. Preferably the catalyst is dimethyl aminopyridine; and the base is triethylamine.
