[OBJECT) TO PROVIDE AN ANTI-SOILING AGENT COMPOUND THAT CAN SUFFICIENTLY PREVENTS ADHESION OF PITCH TO A DRY PART REGION. [SOLUTION] THE PRESENT INVENTION PROVIDES AN ANTI-SOILING AGENT COMPOSITION FOR PREVENTING PITCH CONTAMINATION IN A DRY PART OF A PAPER-MAKING PROCESS, AND THE COMPOSITION HAS A POLYSILOXANE COMPOUND REPRESENTED BY THE FOLLOWING FORMULA (1), WHEREIN THE NUMBER OF AMINO-MODIFIED GROUPS PER MOLECULE OF THE POLYSILOXANE COMPOUND IS IN A RANGE FROM 0.5 TO 5. [WHEREIN, A SUBSTITUENT R1 REPRESENTS A METHYL GROUP OR AN AMINO-MODIFIED GROUP REPRESENTED BY THE FOLLOWING FORMULA (2), AND THE NUMBER N OF REPEATING SILOXANE UNITS REPRESENTS AN INTEGER IN A RANGE FROM 50 TO 1000, AND WHEREIN, EACH OF A SUBSTITUENT R2 AND A SUBSTITUENT R3 INDEPENDENTLY REPRESENTS AN ALKYLENE GROUP HAVING CARBON ATOMS OF 1 TO 6, AND THE NUMBER M OF REPEATING AMINO-ALKYLENE UNITS REPRESENTS AN INTEGER IN A RANGE FROM 0 TO 2].
