Coprocessed tablet excipient composed of chitin and silicon dioxide [52] Chitin is a water-insoluble hydrophilic polymer that can absorb water and function as a disintegrant. Due to the unacceptable flow and compression properties of chitin, coprecipitation with silicon dioxide was used to provide a new excipient with excellent flow, compaction and disintegration properties when compared to the individual components or commercially available direct compression fillers and disintegrants. The optimal composition of the coprocessed excipient contains a silicon concentration of about 50% (w/w). [Pg.88]

Peptide-chitin complexes resulting from peptide synthesis on chitin could prove useful for the induction of antipeptide antibodies. Chitin is stable to the conditions of Fmoc chemistry, including methods used to release peptides. The properties of chitin are similar to those of cellulose. Chitosan, unlike cellulose, does not have to be derivatized to create an amino group for attachment of the linker. [Pg.61]

Only few data are available on the physical properties of chitin in solution due to the difficulties in dissolving this polymer. Solubilization would be necessary to characterize molar mass but also for processing because chitin cannot be processed in molten state. The cohesion of this polymer is too large due to stabilization by a dense hydrogen bond network and thermal decomposition instead of melting occurs upon heating. [Pg.64]

Due to the availability, biocompatibility, biodegradability, nontoxicity, and adsorption properties of chitin and chitosan, they have found extensive use in food processing, water purification, biotechnology, and other industries (Figure 19). [Pg.149]

This chapter reviews applications of chitosan for its bioactive properties and in veterinary drug/ vaccine delivery, and also discusses possibilities and limitations in regard to biopharmaceutical aspects. The properties of chitin and chitosan expected to enhance the therapy in veterinary medicine will be conferred and the future research directions in this field will be indicated. [Pg.461]
