PURPOSE: To obtain a cleaning agent composition for textile containing a surfactant, terpolymer of alkylene, CO and maleic anhydride and zeolite, having excellent effect for re-preventing stain and good biodegradability and causing no enriched nutrition.

CONSTITUTION: The aimed composition containing (A) 5-60wt.% (preferably 10-60wt.%) surfactant, preferably nonionic or anionic surfactant, (B) 0.05-50wt.% (preferably 1-50wt.%) builder salt [preferably alkali (earth) metal salt, ammonium salt or amine salt] of terpolymer copolymer of alkylene, CO and maleic anhydride and (C) zeolite. Furthermore, weight ratio of the component B to component C is 1:50-10:1 (preferably 1:10-1:1).
