PROBLEM TO BE SOLVED: To provide a detergent composition for automatic washing machine capable of reducing corrosion of a gunmetal impeller of an automatic washing machine.SOLUTION: A detergent composition for automatic washing machine contains (a) 0.01-10 mass% of a defoaming agent and (b) 0.01-5 mass% of a corrosion inhibitor, where the defoaming agent is at least one selected from an alkylene oxide additive of polyhydric alcohol represented by formula (1) and polyoxyalkylene monoalkyl ether. In formula (1), Ris a residue obtained by removal of all of hydroxyl groups from C3-20 2-8 valent polyhydric alcohol; AO are each independently C2-4 oxyalkylene groups essentially containing an oxypropylene group; n is an average addition molar number of the oxyalkylene group and is the number of 2-1,000; m is an integer of 2-8; and m pieces of [-O-(AO)n-H] may be the same or different from each other.SELECTED DRAWING: None 【課題】自動洗浄機の砲金製インペラーの腐食を低減することができる自動洗浄機用洗浄剤組成物の提供。【解決手段】（ａ）消泡剤を０．０１〜１０質量％及び（ｂ）腐食防止剤を０．０１〜５質量％含み、消泡剤は、式（１）で表される多価アルコールのアルキレンオキサイド付加物及びポリオキシアルキレンモノアルキルエーテルから選択される少なくとも１種である自動洗浄機用洗浄剤組成物。（Ｒ１はＣ３〜２０の２〜８価の多価アルコールから全部の水酸基を除いた残基；Ａ１Ｏは各々独立に、オキシプロピレン基を必須とするＣ２〜４のオキシアルキレン基；ｎは、オキシアルキレン基の平均付加モル数、２〜１０００の数；ｍは２〜８の整数；ｍ個の〔−Ｏ-（Ａ１Ｏ）ｎ−Ｈ〕は同一でも、異なっていてもよい）【選択図】なし
