Abstract:
A composition of skin external application for improving skin wrinkle or enhancing skin elasticity is provided, which composition has improved activity for collagen and hyaluronic acid synthesis, skin wrinkle improvement, skin elasticity enhancement and skin moisturing. The composition of skin external application for improving skin wrinkle or enhancing skin elasticity comprises 0.001 to 20 wt.% of optia fiacus midia extract, 0.001 to 20 wt.% of Panax schinseng extract, 0.001 to 20 wt.% of Zinnia elegans extract, 0.001 to 20 wt.% of rasberry extract and 0.001 to 20 wt.% of Crataegi Fructus extract.
Abstract:
PURPOSE: Provided are a polymer capsules containing thymol ester of 3,4,5-trimethoxy cinnamic acid, a method for preparing thereof and a cosmetic composition containing thereof. CONSTITUTION: The method comprises steps of (a) dissolving a polymer in solvent; (b) evenly dissolving thymol ester of 3,4,5-trimethoxy cinnamic acid in the polymer solution with dispersing it; (c) emulsifying the polymer solution containing the thymol ester of 3,4,5-trimethoxy cinnamic acid in a dispersion stabilizer to obtain an emulsion; and (d) removing solvent from the emulsion to obtain hard polymer capsule. The cosmetic composition comprises the polymer capsule containing the thymol ester of 3,4,5-trimethoxy cinnamic acid as an effective ingredient.
Abstract:
PURPOSE: Provided are multi-hollow polymer microcapsules containing L-ascorbic acid, a preparation process thereof and a cosmetic composition containing the same. The multi-hollow polymer microcapsule containing L-ascorbic acid has excellent stability, and is thus effectively used in the application of L-ascorbic acid as an active ingredient and useful in the cosmetic industry especially manufacturing skin wrinkle care products and skin whitening products. CONSTITUTION: Multi-hollow polymer microcapsules containing L-ascorbic acid are characteristically stabilized by cross-linking of a gelling agent and ion screening agent, wherein the gelling agent is selected from the group consisting of arabic, tragacanth, karaya, larch, ghatti, locust bean, guar, alginate, carrageenan, furcellaran, pectin, gelatin, starch, and derivatives thereof; dextran, xanthan gum and derivatives thereof; and vinyl polymer, acryl polymer, polyol and derivatives thereof, and the ion screening agent is selected from the group consisting of monovalent slats, such as sodium chloride, sodium phosphate, and the like; bivalent salts, such as magnesium sulphate, calcium chloride, copper chloride and the like; multi valent salt derivatives; and mixture thereof.
