Novel cationized chitin and its production

Abstract

Abstract PURPOSE:A water-soluble cationized chitin suitable for use in cosmetics, perfumes, toiletries, etc., prepared by replacing the reactive hydrogen atoms of chitin by quat. nitrogen-containing groups and cleaving its intermolecular hydrogen bonds. CONSTITUTION:A cationized chitin prepared by replacing the reactive hydrogen atoms in a chitin molecule by quat. nitrogen-containing groups represented by formula I (wherein R is methyl or ethyl and X is a halogen) and cleaving the intermolecular hydrogen bonds. Said modified chitin is produced by reacting 100pts.wt. chitin with at least about 30pts.wt. cationizing agent [e.g., a compound of formula II or III (glycidyltrialkylammonium or 3-chloro-2-hydroxypropyl- trialkylammonium salt)] in the presence of an alkali in an aqueous solvent (water and/or an alcohol), neutralizing and washing the product and dissolving it in, e.g., an aqueous chloride solution (>=about 1N) to cleave the intermolecular hydrogen bonds.
