Abstract:
PURPOSE: A method of producing corneocyte containing a hydrogel particle containing factor for moisturizing and a lipid-coated hydrogel particle is provided to moisturize to capture water thanks to cellulase. CONSTITUTION: Corneocyte comprises a hydrogel particle comprising a particle with factor for moisturizing and a lipid-coated hydrogel particle. Lipid is soybean lecithin, phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine, phosphatidylglycol or hydrogenated phosphatidylcholine. The content of lipid is from twice to ten times the dry weight of hydrogel. The factor for moisturizing is amino acid, sodium pyrrolidone carboxylate and sodium lactate or urea. Amino acid is serine, glycine, arginine, glutamic acid, tyrosine or alanine. The content of the factor for moisturizing weighs 5-30% against corneocyte. A method of producing corneocyte comprises the following step.(a) Lipid dissolves in an organic solvent.(b) The particle for moisturizing is dispersed in the lipid dissolved solvent.(c) A hydrogel particle made of water soluble macromolecules and the water soluble crosslink agent are dispersed in the solution obtained in the step(b).(d) Water is added to the produced solution in step(c). Then, the solution produced in step(d) is decompressed and distillated. A cosmetic composition comprises corneocyte as an active ingredient.
Abstract:
PURPOSE: A cosmetic composition containing natural inorganic tackifier and anionic surfactant is provided to stabilize skin active ingredients and to improve long-term stabilization. CONSTITUTION: An emulsification stabilized cosmetic composition contains 0.1-2.0 wt% of natural inorganic tackifier and 0.05-0.5 wt% of anionic surfactant. The natural inorganic tackifier is magnesium silicate, magnesium aluminum silicate, sodium magnetsium silicate, or bentonite. The anionic surfactant is sodium stearoyl glutamate, potassium cetylphosphate, or mixture thereof. The natural inorganic tackifier and anionic surfactant stabilizes skin active ingredients such as oleanolic acid, enzyme-treated red ginseng saponin, or Rheum coreanum extracts.
Abstract:
PURPOSE: A cosmetic composition for skin moisturizing containing colophony extract and red pine needle and root extract is provided to improve moisturizing and skin condition. CONSTITUTION: A cosmetic composition for improving skin moisturizing contains colophony extract and red pine needle and root extract as active ingredients. A cosmetic composition for improving skin condition contains colophony extract and red pine needle and root extract as active ingredients. Each active ingredient is contained in 0.001-10 weight%.
Abstract:
The present invention relates to a low viscous cosmetic composition using a natural emulsifying agent and, more specifically, to a cosmetic composition which uses natural saccharide surfactants instead of using chemical surfactants and implements a low-viscous formulation whereby it is safe for the skin and provides a feeling of use that the absorption is fast. In addition, the formulation is stable and is effective in enhancing the moisture of the skin.
