PROBLEM TO BE SOLVED: To provide a liquid cleanser composition which has good impregnability and cleansability for delicate fibers, gives good washing finish touches to fibers, and has excellent temporal stability. SOLUTION: This liquid cleanser composition is characterized by comprising 10 to 50 mass% of nonionic surfactants comprising the following primary alcohol-ethylene oxide adducts (a) and (b) in a (a)/(b) weight ratio of 1/5 to 5/1, (c) 0.1 to 10 mass% of a compound represented by formula (3) [R<SP>3</SP>and R<SP>4</SP>are each a 1 to 4C alkyl or hydroxyalkyl; R<SP>5</SP>is a 1 to 4C divalent hydrocarbon group; A is a group represented by formula (4) or (5); R<SP>6</SP>and R<SP>7</SP>are each a monovalent hydrocarbon group], and (d) 5 to 20 mass% of a hydrotropic agent. Herein, (a) is a compound of formula (1) : R<SP>1</SP>O(CH<SB>2</SB>CH<SB>2</SB>O)<SB>n</SB>H [R<SP>1</SP>is a monovalent hydrocarbon group having a branching degree of≤70%; (n) is 10 to 20], and (b) is a compound of formula (2) : R<SP>2</SP>O(CH<SB>2</SB>CH<SB>2</SB>O)<SB>m</SB>H [R<SP>2</SP>is a monovalent hydrocarbon group having a branching degree of≥80%; (m) is 5 to 15].
