Patent

CA 2603139

The present invention relates to a modified polysaccharide prepared from the reaction between a polysaccharide comprising a plurality of monosaccharide subunits having at least one primary amino group, and an hydrophobic aldehyde. The aldehyde and the amino group form together an imine or amine group. The process for preparation and use in cosmetic, pharmaceutical and food industry of the modified polysaccharide is also disclosed.

La présente invention concerne un polysaccharide modifié préparé à partir de la réaction entre un polysaccharide qui comprend une pluralité de sous-unités de monosaccharides ayant au moins un groupe amino primaire et un aldéhyde hydrophobe. L~aldéhyde et le groupe amino forment ensemble un groupe imine ou amine. L~invention décrit également le procédé pour la préparation et l~utilisation du polysaccharide modifié dans l'industrie cosmétique, pharmaceutique et alimentaire.
