PRODUCTION OF SUSTAINED RELEASE ANTIBACTERIAL MATERIAL, SUSTAINED RELEASE ANTIBACTERIAL MATERIAL PRODUCED THEREBY AND ITS USE

摘要

PURPOSE: To provide a process for producing a sustained release antibacterial material having stable and excellent sustained release performance, usable under non-sealed condition and enabling the support of an antibacterial component efficiently and economically on an inexpensive safe carrier. ;CONSTITUTION: This invention relates to (1) a process for producing a sustained release antibacterial material by dissolving a volatile antibacterial substance in an organic solvent, mixing with starch, distilling out the organic solvent to obtain a sustained release antibacterial material and partly removing the volatile antibacterial substance from the antibacterial material by vacuum drying, (2) a sustained release antibacterial material produced by the process and (3) a freshness-keeping agent composed of the sustained release antibacterial material.;COPYRIGHT: (C)1996,JPO
