Abstract:
PURPOSE: Provided is a stabilized silver colloidal composition with good stabilization against agglomeration, oxidation and discoloration, and high antibacterial property by treating Ag colloidal solution with nitrogen-contained polymer and metal chelate. CONSTITUTION: The stabilized silver colloidal composition comprises the components of: 0.0001-5wt.% of Ag colloidal solution; 0.01-10wt.% of at least one water soluble polymer containing nitrogen selected from chitin, gelatin, collagen, polyacryl amide, etc.; 0.001-50wt.% of at least one metal chelate selected from ethylene diamine tetraacetic acid(EDTA), citric acid, beta-alamine diacetic acid, etc.; and the rest of water. The stabilized Ag colloidal composition is prepared by dropping Ag colloidal solution obtained by dispersing Ag particles(
Abstract:
PURPOSE: Provided are a base composition for blocking ultraviolet rays and a cosmetics containing the same. The composition has no gelation, gives pleasant feeling in use and blocks ultraviolet rays excellently. CONSTITUTION: In the composition containing titan dioxide microparticles, a dispersing medium and a dispersing agent, the titan dioxide microparticle is coated with alkyltriethoxysilane of the formula(1) and the coated titan dioxide microparticle is dispersed into a nano sized particle. In the formula(1), R1 is C3-C22 alkyl, and R2 is C1-C22 alkyl.

Abstract:
PURPOSE: A pressed powder composition for coloring cosmetic containing pre-binder powders is provided, which controls quantity of pay-off easily, and improves adhesion ability between each particle and between particle and skin, so controls shades of color when the composition applied on skin, maximize pearl effect, and enhances maintenance of cosmetic. CONSTITUTION: A process for the preparation of pre-binder powders comprises of: (1)pouring distilled water to powdered particle Mica, shaking at 80°C; (2)pouring paraffin wax and a surfactant to isopropylalcohol, heating to 65°C to get a surface-treating agent; (3)pouring the surface-treating agent in (2) to the hydrophase powdered particle by (1) slowly, shaking for 1hr, and refrigerating rapidly to lower than 30°C at more than 1°C/min of refrigerating rate; (4)leaving the composition of (3) for more than 12hrs, and drying at 85-95°C for more than 6hrs to get the pre-binder powder that surface-treated with wax. The pressed powder composition for coloring cosmetic contains 10-100wt.% of pre-binder powders.
Abstract:
PURPOSE: A cosmetic composition showing inhibition effect on collagenase formation by containing green tea polyphenol is provided, which shows excellent inhibition effect on collagen degradation. CONSTITUTION: A process for the preparation of cosmetic composition showing inhibition effect on collagenase formation comprises the steps of: adding green tea(Thea sinensis L.) to 95% ethanol, steeping for 5days, and filtering; separating organic solvent layer by using distilled water/ethyl acetate(1:1) solution; purifying 99% of (-)-epicatechin(EC), (-)-epigallocatechin(EGC), (-)-epicatechin 3-gallate(ECG), and epigallocatechin 3-0-gallate(EGCG) by separating with high performance liquid chromatography, and producing the green tea polyphenol (GTP). The cosmetic composition contains 0.00000001-30%(w/v) of GTP, desirably 0.00001-6%(w/v), as the weight after drying.
Abstract:
PURPOSE: A cosmetic composition containing an extract of Panax ginseng C.A Meyer for prevention of skin aging is provided. The Panax ginseng C.A Meyer extract has effects on proliferation of skin cell and facilitation of collagen biosynthesis, so that the skin aging can be effectively prevented. CONSTITUTION: A cosmetic composition for prevention of skin aging contains an extract of Panax ginseng C.A Meyer, wherein the amount of the Panax ginseng C.A Meyer extract contained is 10 superscript -8(0.00000001) to 10 wt.%; the Panax ginseng C.A Meyer extract is prepared by the steps of: extracting Panax ginseng C.A Meyer with ethanol; heat-extracting insoluble remnants of Panax ginseng C.A Meyer and filtering the extract; and adding ethanol into the filtered extract to obtain the precipitated ginseng polysaccharides.
