  • Patent number: 8277848
    Abstract: Disclosed herein is a method for preparing an aqueous solution of high-concentration calcium phosphate, the method comprising the steps of: preparing an acidic aqueous solution using an acidic chelating agent; and dissolving a calcium phosphate-based compound in the acidic aqueous solution, and then adding a pH-adjusting agent to the acidic aqueous solution to adjust the pH of the acidic aqueous solution. The disclosed aqueous solution does not form a precipitate after neutralization so that it can be used in various calcium-containing products, including foods, drugs, or quasi-drugs.
    Type: Grant
    Filed: July 19, 2011
    Date of Patent: October 2, 2012
    Assignee: Bioalpha Inc.

  • Publication number: 20120093895
    Abstract: The present invention relates to a bone-repair composition comprising a micro-pulverized demineralized bone matrix; a nonmicro-pulverized demineralized bone matrix; and a hydrating material. The bone-repair composition of the present invention provides easier injectability and shape-maintenance (handling), and exhibits excellent bone-repairing effects due to a large surface area of the micro-pulverized demineralized bone matrix and an early release of the bone growth factors, compared with conventional compositions comprising the nonmicro-pulverized demineralized bone matrix alone. It also has an advantage of being biocompatible and harmless to the human body because there is no use of synthetic materials.
