Beschreibung

Anwendung

Gelbildend mit multivalenten Anionen. Ergibt eine klare Lösung, die zu einem starken, klaren Film trocknet.

Shrimp shell derived chitosan, deacetylated chitin (poly β-1,4-D-glucosamine), may be used as a biocompatible, antibacterial and environmentally friendly polyelectrolyte biomaterial with a variety of applications including uses in water treatment, chromatography, additives for cosmetics, textile treatment for antimicrobial activity, novel fibers for textiles, photographic papers, biodegradable films, biomedical devices, and microcapsule implants for controlled release in drug delivery. It may be derivatized to further expand its uses.

Leistungsmerkmale und Vorteile

Biokompatibles, antibakterielles und umweltfreundliches Polyelektrolyt für eine Vielzahl von Anwendungen, einschließlich Wasseraufbereitung, Chromatographie, Additive für Kosmetikprodukte, Textilbehandlung für antimikrobielle Aktivität, neuartige Fasern für Textilien, Fotopapier, biologisch abbaubare Filme, biomedizinische Produkte und Mikrokapselimplantate für die kontrollierte Freisetzung von Arzneimitteln.

Qualität

May contain foreign matter.

Angaben zur Herstellung

Prepared by the alkaline deacetylation of chitin obtained from the shells of shrimp (Pandalus borealis). Chitin is manufactured industrially by crushing shrimp shells, then washing the solids with acids to remove inorganic and proteinaceous material. The purified chitin is deacetylated to chitosan by treatment with a strong base such as sodium hydroxide. The resulting chitosan may be further purified by preparation of solutions in acid followed by neutralization and precipitation.

Hinweis zur Analyse

The degree of acetylation may be determined by dye binding or titration methods.
