Abstract: The present invention relates to hydrogel particles coated with lipid, which are made from dispersing hydrogel particles in an organic solvent in which lipids are dissolved, and to a method for manufacturing same. Unlike the existing method for manufacturing hydrogel core vesicles, the present invention can effectively manufacture same by using an emulsification method, without involving the steps of chemical treatment of the surface of hydrogels or dilution, thereby facilitating mass production and preventing the decrease of drug encapsulation efficiency.

Abstract: The present invention relates to a composition for removing keratinous skin material, the composition comprising a Lactobacillus strain or a culture thereof. Also, the present invention relates to a composition for removing keratinous skin material, the composition comprising green tea Lactobacillus as Lactobacillus. In contrast to when skin is improved through the supply of a moisture fraction by a commonly used skin-moisturizing component, the Lactobacillus according to the present invention removes keratinous skin material, thereby producing the advantageous effect that skin can be cared for and improved as the waste materials which accumulates on the skin is fundamentally removed. Therefore, the composition according to the present invention can effectively prevent or alleviate skin problems such as spots. Also, the invention regulates the skin and so improves skin tone by removing surplus keratinous material which is not needed by the skin.

Abstract: Disclosed are a method for preparing coumestrol and a method for preparing coumestrin preparation, wherein chitosan is treated for a predetermined amount of time during a bean growth period. Additionally, disclosed is the method for preparing coumestrol by performing an enzyme treatment or an acid treatment and the like on the coumestrin prepared by the preparation method.

Abstract: The present invention relates to a cosmetic composition which mimics the extracellular matrix to stimulate the regeneration of skin cells, and more particularly to a cosmetic composition which contains active ingredients consisting of low-molecular-weight materials, which easily permeate through the skin, at a composition ratio similar to that in the extracellular matrix. The cosmetic composition stimulates the repair of the skin to maintain homeostasis and is effective for the regeneration of skin cells.

The cationic polymer nanocapsules have a molecular weight of 5,000-100,000, a surface potential of 5-100 mV and a particle size of 50-500 nm. Also, disclosed is a cosmetic composition containing said cationic polymer nanocapsules.

Abstract: The present invention provides a method for manufacturing a large-area film, the method comprising the steps of: dispersing various fine particles in a polar solvent to prepare a dispersion; adding water to the dispersion to prepare a mixture; and adding an organic solvent capable of generating Rayleigh-Benard convection to the mixture to induce the interfacial assembly of the fine particles, thereby forming the film. The invention also provides a large-area film manufactured by the method. According to the invention, a large-area, high-purity film can be quickly manufactured by a simple solution process, and the manufactured large-area film has excellent physical and electrical properties, and thus can be used in various applications.

Abstract: Provided are: a multi-layered lamellar granule comprising a nucleating agent, a ceramide-containing artificial stratum corneum lipid lamellar layer which encases the nucleating agent and a polymer layer disposed on the artificial stratum corneum lipid lamellar layer; and an external skin application composition comprising the same. The external skin application composition shows improved moisturizing and barrier repair capabilities when applied to the skin, which can be advantageously used in cosmetics and pharmaceuticals.
