  • Novel Core-Shell Structure
    Publication number: 20110177306
    Abstract: To provide a new structure-dispersed composite in which a substance poorly soluble in a medium is dispersed as micronized particles, a core-shell structure is dispersed in the medium, wherein said core-shell structure contains microparticles therein, and consists of a core comp rising a core compound that is poorly soluble in said medium and a liquid shell comprising a shell compound that is poorly soluble in said medium, and the mean diameter of said core-shell structure is 10 ?m or less.

  • GRANULE DISPERSION COMPOSITION, PROCESS FOR PRODUCING THE SAME, AND GRANULAR MATERIAL AND MEDICINE
    Publication number: 20090028950
    Abstract: The subject matter of the present invention is to provide a new particulate material dispersion composite in which a material poorly soluble in water is micronized and dispersed. For the above purpose, a particulate material dispersion composite is produced in the present invention, wherein a particulate material containing a specific material which is poorly soluble in water, a polymer and a lipid is dispersed in water, the mean diameter of said particulate material is 1 ?m or less, and the ratio of the combined weight of said polymer and said lipid to the weight of said specific material is 1.5 or larger.
