  • Method for improving water solubility of slightly soluble substance
    Patent number: 9248103
    Abstract: It is an object of the present invention to provide a method for improving the solubility of a poorly-soluble substance, which is capable of increasing the solubility of substantially all poorly-soluble substances. This is a method comprising coating the surface of a poorly-soluble substance particle with microparticles of a calcium compound such as calcium phosphate or calcium carbonate, and at least one selected from a pH adjuster and a surfactant, by applying mechanical energy thereto.
    Type: Grant
    Filed: February 21, 2013
    Date of Patent: February 2, 2016
    Assignee: KABUSHIKI KAISHA SANGI
    Inventors: Shuji Sakuma, Keiichiro Kikukawa, Ryosuke Miyasaka
  • Method for improving the aqueous solubility of poorly-soluble substances
    Patent number: 9023398
    Abstract: Provided is a method for increasing the solubility of a poorly-soluble substance used in pharmaceutical products, veterinary pharmaceutical products, quasi-drugs, cosmetic products, food products, agricultural chemicals, and the like, without using large amounts of additives. This is a method for improving aqueous solubility, which comprises coating the surface of the particle of a poorly-soluble substance used in pharmaceutical products, veterinary pharmaceutical products, quasi-drugs, cosmetic products, food products, agricultural chemicals, and the like, with microparticles of a calcium compound such as calcium phosphate or calcium carbonate.
