Cationic Starch

The repeating unit of starch is glucose, having a carbohydrate monomer composition of C6H12O6. In the polymer each unit has three -OH groups, and the units are linked together with flexible alpha-1-4 glycocidic bonds. Cationic starch is produced by treating a slurry of partially swollen granules of starch with a reactive compound. An example of such a reagant is epoxypropyltrimethylammonium chloride. This reagant contains a quaternary nitrogen, yielding a positive charge that is independent of pH. The reagent usually attaches to the starch at the C6 position, the most accessible of the -OH groups. The typical level of derivatization is one to two charged groups per hundred glucose units. Because the reaction is usually carried out in a slurry, it is expected that the distribution of charged groups will be highly non-uniform. Also, there is reason to believe that treatment of potato starch or dent corn starch will result in preferential cationization of the linear amylose chains. The branched amylopectin chains of starch tend to be more crystalline in the solid starch granule, and therefore less accessible to treatments. Cationic starch is usually delivered in a dry powder form (10 to 20% moisture content).

 

Cationic Starch can be used as Dry strength, emulsification of sizing agents, part of many retention and drainage programs
