To provide a detergent composition which is received in a pump foamer container and the like, does not cause operating problems due to clogging even with repetitive use, and has an excellent foam elasticity, sustainability, and feeling of use after being rinsed off. This detergent composition is characterized by containing: a soap to be obtained by neutralizing a higher fatty acid to N-methyl taurine sodium； and a polymer having a molecular weight of 200,000 or less and including a dimethyldiallylammonium chloride as a monomer unit.本發明之課題在於提供一種洗淨劑組成物，其收容於泵式起泡容器等，即便反覆使用亦不會產生由堵塞所導致之作動不良，且泡沫之彈性、持續性及沖洗後之使用感優異。 本發明之洗淨劑組成物之特徵在於含有：藉由利用N-甲基牛磺酸鈉中和高級脂肪酸而獲得之肥皂；及分子量20萬以下之聚合物，其含有二甲基二烯丙基氯化銨作為單體單位。
