PROBLEM TO BE SOLVED: To provide a pitch-controlling agent capable of dispersing a tacky pitch component in a papermaking system to form stable pitch particles and setting the pitch particles onto stock pulp to discharge the pitch component out of the papermaking system. SOLUTION: The pitch-controlling agent comprises a low-viscosity cationized starch≥0.2 in N value and 2-500 mPas in viscosity of a 15% aqueous solution at 25°C. COPYRIGHT: (C)2004,JPO&NCIPI
