A method for controlling Pitch and Stickies is disclosed. The method
comprises adding hydrophobically modified hydroxyethyl cellulose (HMHEC)
and cationic polymers to a cellulosic fiber slurry (pulp) or to a paper
process or to a paper making system and results in a higher degree of
inhibiting organic deposition and retention of pitch on paper fiber as
compared to the inhibition of the individual ingredients. The combination
of HMHEC and cationic polymers surprising results in a synergistic
effect.
