PROBLEM TO BE SOLVED: To provide a highly water-dispersible powder that, though containing a sparingly water-soluble component, exhibits high water-dispersiblity which is stable even after the lapse of time, and its manufacturing method.SOLUTION: The highly water-dispersible powder comprises the sparingly water-soluble component, a water-soluble polymer having protective colloid performances, and saponins. The highly water-dispersible powder can be manufactured by a method comprising an emulsification step for preparing an emulsion by emulsifying the sparingly water-soluble component, in the presence of the water-soluble polymer having protective colloid performances and saponins, in an aqueous solvent and a drying step for drying the emulsion.COPYRIGHT: (C)2008,JPO&INPIT【課題】水難溶性成分を含有するにもかかわらず高水分散性を示し、しかも高水分散性が経時的に安定な高水分散性粉末とその製造方法の提供。【解決手段】水難溶性成分と、保護コロイド能を有する水溶性高分子と、サポニン類とを含有する高水分散性粉末により解決される。この高水分散性粉末は、保護コロイド能を有する水溶性高分子とサポニン類との存在下で、水難溶性成分を水性溶媒中で乳化して、エマルジョンを調製する乳化工程と、エマルジョンを乾燥する乾燥工程とを有する方法により製造できる。【選択図】なし
