Abstract:
Disclosed herein is a method for preparing a powder having a surface modified with a water-repellent ultra-thin layer. The disclosed preparation method comprises modifying the powder with the water-repellent ultra-thin layer by a vapor phase reaction using a high-boiling-point acryl silicone OEt-based compound and branched alkyl-silicone OEt-based compound and an alkylsilane having relatively low boiling point. When the powder is used in cosmetics, it shows excellent usability due to improved water repellency.

Abstract:
A method for reforming the surface of inorganic particles is provided to increase the serum absorption capability when the inorganic particles are applied to cosmetics by enlarging the surface area through tens of nanometers of etching, increasing the absorption using a coating material, and improving the whiteness, thereby preventing the collapse of make-up and improving darkness and dullness of the make-up. A method for improving oil absorption, whiteness, or water repellency by reforming the surface of inorganic particles comprises the steps of: (a) etching the surface of the inorganic particles using an acid to form an irregular surface layer; (b) treating the etched inorganic particles with high energy in accordance with the energy requirement; (c) washing, filtering, drying and crushing the high energy treated inorganic particles; and (d) coating the inorganic particles obtained from the step(c) with a surface treating agent such as dimethicone, methicone, triethoxycaprylylsilane, acrylates/tridecyl acrylate/triethoxysilylpropyl methacrylate/dimethicone methacrylate copolymer and triethoxysilylethyl polydimethyl siloxy ethylhexyl dimethicone.

The acid is at least one selected from the group consisting of hydrofluoric acid, nitric acid, acetic acid, hydrochloric acid, and phosphoric acid. The high energy source is at least one selected from the group consisting of microwave energy, ultrasonic energy, plasma, and heating.
Abstract:
A method for economically preparing a mesoporous molecular sieve material through a more simplified preparing process while maintaining structural uniformity of the mesoporous silica material by substituting metal elements within the skeleton of a mesoporous silica material, and a molecular sieve material prepared by the method are provided. A method for preparing a mesoporous molecular sieve material in which metal elements are substituted within a skeleton structure comprises the steps of: (A) dissolving a surfactant into distilled water, dissolving a metal precursor into an acid, and mixing the dissolved solutions with each other; (B) adding a precursor into the mixture obtained in the step(A), neutrally adjusting pH of the mixture, and subjecting the pH adjusted mixture to hydrothermal reaction; (C) filtering, cleaning and drying the material obtained in the step(B); and (D) calcining the material obtained in the step(C) to remove the surfactant from the material, wherein a silica to substituted metal ratio is in a range from 5:1 to 20:1 within the skeleton of a mesoporous silica powder substituted for the metal elements. The metal precursor is at least one selected from the group consisting of titanium alkoxide, titanium sulfate, titanium tetrachloride(TiCl4), zinc tetrachloride(ZnCl4) and zinc acetate.
