PROBLEM TO BE SOLVED: To provide a washing resin composition capable of simply performing the substitution with a post-resin and the removal of foreign matter with respect to a resin easy remaining in a molding machine, enhanced in purging/washing effect even if the use amount of a detergent is little, suppressing the adhesion to the inner surface of the molding machine at a washing temperature and capable of rapidly performing the substitution with the post-resin by easily discharging the detergent itself from the molding machine. SOLUTION: The washing resin composition of the molding machine comprises 0.1-100 pts.wt. of a polyalkylene oxide or polyalkylene glycol (C) with a viscosity average molecular weight of 10,000-1,500,000 and 0.1-10 pts.wt. of an anionic surfactant being a sulfate or sulfonate having a 8-20 C alkyl group and/or a metal salt of a 6-22C fatty acid (D) based on the 100 pts.wt. of a mixture of 20-99 wt.% of an olefinic thermoplastic resin (A) and 1-80 wt.% of an unsaturated group-containing carboxylic acid modified olefinic resin (B).
