Abstract

This invention relates to a liquid composition for the control of pitch deposition in pulp and paper making comprising an aqueous solution of (1) a derivatized cationic guar, and (2) styrene maleic anhydride copolymer. The invention also relates to a process for inhibiting pitch deposition in pulp and papermaking systems and on papermaking equipment.
