Description

General description

Glycidyltrimethylammonium chloride (GTMAC) is a cationizing agent commonly used for starch modification.

Application

Glycidyltrimethylammonium chloride be used as a derivatizing agent to synthesize N-(2-hydroxypropyl)-3-trimethylammonium chitosan chloride (HTCC), a water-soluble chitosan derivative, by reacting with chitosan. HTCC can form nanocomposite films with silver nanoparticles that show good antimicrobial property and optical transparency. Cationic starches can also be prepared by derivatization of starch with GTMAC.

Packaging
