Title:
PROCESS FOR PRODUCING POWDERY COMPOSITION AND POWDERY COSMETIC
Document Type and Number:
WIPO Patent Application WO/2010/107010
Kind Code:
A1
Abstract:
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 mm2/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.
