not employed in the method the composition may be added to a papermaking process in an amount effective to reduce deposition of hydrophobic contaminants when compared to a papermaking process in which the composition is not employed for example the composition may be added to pulp slurry in an amount from about 10 ppm to about 300 ppm e g from about 50 ppm to about 200 ppm or about 50 ppm 60 ppm 70 ppm 80 ppm 90 ppm 100 ppm 110 ppm 120 ppm 130 ppm 140 ppm 150 ppm 160 ppm 170 ppm 180 ppm 190 ppm to about 200 ppm the effective amount may reduce the deposition of hydrophobic contaminants by at least 5 to about 95 e g about 5 6 7 8 9 10 15 20 25 30 35 40 45 50 u00b0 55 60 65 70 75 80 85 90 or 95 when compared to a papermaking process in which the composition is not employed the method may further include adding to the papermaking system at least one component selected from the group consisting of fixatives detackifiers and other dispersants in at least one embodiment the glycerol based polymer may be any polymer containing repeating glycerol monomer units such as polyglycerols polyglycerol derivatives and polymers consisting of glycerol monomer units and at least one other monomer unit regardless of the sequence of monomers unit arrangements suitably other monomers may be polyols or.
