摘要:
Disclosed is a process for producing a powdery cosmetic having an excellent feeling upon application, an excellent long-lasting property and excellent production efficiency. Specifically disclosed is a process for producing a powdery composition, which comprises: a slurry preparation step of mixing a powder component with a non-volatile oily component in a volatile solvent to prepare a slurry, wherein the non-volatile oily component comprises (A) an amino-modified silicone having a functional group equivalent of 1000 to 10, 000 and a viscosity of 200 to 2000 mm 2 /s at 25°C and (B) a lipophilic nonionic surfactant; and a drying step of drying the slurry to produce the powdery composition, wherein a drying apparatus to be used for the drying step can dry the slurry in such a manner that the slurry is divided into fine droplets by means of a mechanical shearing force and a drying gas is blown to the fine droplets. Also specifically disclosed is a powdery cosmetic having the above-mentioned properties, which is prepared from a powdery composition produced by the process.

The present invention provides a W/O emulsion cosmetic excellent in the feeling in use and stability. The W/O emulsion cosmetic of the present invention comprises the following components (A) to (F): (A) 0.1 to 5 mass % of polyoxyalkylene/alkyl-comodified silicone; (B) polyoxyalkylene-modified silicone, being 0.2 to 3 times in mass with respect to the component (A); (C) 5 to 50 mass % of powder; (D) 10 to 50 mass % of a volatile oil; (E) 1 to 20 mass % of ethanol; and (F) water. In addition, the dispersion stability of powder and viscosity stability of the composition can be improved, by further blending sodium glutamate or by further blending an organically modified clay mineral and diglyceryl isostearate therein. Furthermore, if glycerin and a specific nonvolatile oil are blended therein, the moisturizing property can be improved.

Provided is a titanium dioxide powder having excellent red light-selective transmission function while maintaining hiding power. Also Provided is a cosmetic formulated therewith that provides a natural finish and makes skin irregularities such as pores inconspicuous while having covering power for blotches, freckles, etc.
摘要:
A method for producing cosmetics, characterized in that it comprises a step of dispersing a powder component in an oil component or an aqueous component by means of a media mill; a method for producing cosmetics comprising a step of imparting hydrophobic property to a powder by the use of a media mill; and a method for producing cosmetics comprising using a dispersion of a hydrophobic powder containing a clay mineral modified by an organic material. The method is suitable for powder cosmetics, oil cosmetics, emulsion cosmetics and lip colors and can be used for producing powder-containing cosmetics having improved feelings in use and being capable of satisfactorily exhibiting the functionality of the powder.

The present invention provides an ultraviolet absorber-including clay mineral, which allows an ultraviolet absorber to be blended, as a powder component, into cosmetic preparations, can effectively absorb a wide range of ultraviolet light, and has excellent inclusion amount and inclusion strength; and cosmetics containing the same. The ultraviolet absorber-including clay mineral is characterized in that a polybase and an anionic ultraviolet absorber are intercalated between the layers of a water-swellable clay mineral. The polybase is preferably a polymer having a nitrogen-containing group that can become a cation. The anionic ultraviolet absorber is preferably one or more selected from 2-phenylbenzimidazole-5-sulfonic acid, 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid, and their sodium salts.
