| titleOfInvention | Process for Producing Microcapsule of Hydrophobic Drug |
| abstract | The present invention relates to a method for producing microcapsules of a drug (hydrophobic substance) having low solubility in water, and a microencapsulation composition. It is difficult to microencapsulate a drug which is easy to decompose by the conventional heating method. The present invention emulsifies and disperses a mixed solution of an isocyanate compound and a hydrophobic material in an aqueous solution of a polymer dispersant having a hydroxyl group in a molecule, and reacts the isocyanate compound with water at 40 ° C. or lower to form a microcapsule film with urea resin produced thereby. To obtain microcapsule slurry and microcapsule powder. Therefore, microencapsulation of a drug that is susceptible to degradation can be facilitated, and long-term stability can be imparted to an unstable drug by microencapsulation. In addition, microencapsulation compositions can be obtained economically. |
