DETERGENT FOR DISHWASHER

PROBLEM TO BE SOLVED: To provide a detergent for a dishwasher which has excellent detergency to oily soils while securing low-foaming properties, reduces a residual odor such as food odor in a dishwasher case after cleaning and also reduces a residual flavor originated from perfume components.SOLUTION: There is provided a detergent for a dishwasher which comprises a combination of (a) component: a compound represented by the general formula (a-1), (b) component: an anionic surfactant and (c) component: a perfume composition in which the content of a perfume component having a ClogP value of 2 to 5 is 30 mass% or more and the content of a perfume component having a ClogP value of more than 5 is less than 5 mass% in a specific mass ratio. In the formula (a-1), Rrepresents an alkyl group having 13 to 21 carbon atoms; Rrepresents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms or a hydroxyalkyl group having 1 to 4 carbon atoms; Rrepresents an alkylene group having 1 to 4 carbon atoms; and Rand Rrepresent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms. 【課題】低泡性を確保しつつ、油汚れに対して優れた洗浄力を有するとともに、洗浄後の食器洗い機庫内における食材臭などの臭い残りが低減され、洗浄対象物への香料成分由来の香り残りも低減された食器洗い機用洗浄剤を提供すること。【解決手段】（ａ）成分：一般式（ａ−１）で表される化合物と、（ｂ）成分：陰イオン界面活性剤と、（ｃ）成分：ＣｌｏｇＰ値が２〜５である香料成分が３０質量％以上、かつ、ＣｌｏｇＰ値が５超である香料成分が５質量％未満である香料組成物と、を特定の質量比で併用した食器洗い機用洗浄剤。式（ａ−１）中、Ｒ１は、炭素数１３〜２１のアルキル基又はアルケニル基を表す。Ｒ２は、水素原子、炭素数１〜４のアルキル基又は炭素数１〜４のヒドロキシアルキル基を表す。Ｒ３は、炭素数１〜４のアルキレン基を表す。Ｒ４及びＲ５は、水素原子又は炭素数１〜４のアルキル基を表す。［化１］【選択図】なし
