  • Method of solubilizing poorly soluble/insoluble active material through formation of oligomer composite
    Patent number: 9139703
    Abstract: Provided is a method of solubilizing a poorly soluble/insoluble active material through formation of an oligomer composite, in which a structure having a hydrophobic cavity structure is formed by using oligomers derived from two types of hydrophilic natural polymers and a poorly soluble/insoluble component is encapsulated in the cavity structure, and thus, self-aggregation of the poorly soluble/insoluble material is prevented and simultaneously, thermodynamic stability increases to effectively solubilize the poorly soluble/insoluble material.
    Type: Grant
    Filed: October 15, 2010
    Date of Patent: September 22, 2015
    Assignee: BIOGENICS, INC.
    Inventors: Chul-Hwan Kim, Seung-Hak Ko, Jae-Seong Shim, Eun-Kyoung Kwon, Yong-Han Choi
