Abstract:
1. A liquid detergent composition, comprising components (a) to (d), wherein the total content of the components (a) to (c), (a)+(b)+(c), is from 49 to 80% by mass; a mass ratio of the components (a) to (b), (a)/(b), is from 50/50 to 90/10; a mass ratio of the total of the components (a) and (b) to the component (c), [(a)+(b))/(c), is from 90/10 to 70/30, and a mass ratio of the total of the components (a), (b), and (c) to the component (d), [(a)+(b)+(c)]/(d), is from 85/15 to 65/35: component (a): from 15 to 60% by mass of a nonionic surfactant produced by adding p1 mol of ethylene oxide to a compound represented by the formula R—OH, wherein R represents a hydrocarbon group having from 8 to 18 carbon atoms, then adding q1 mol of an alkylene oxide having from 3 to 5 carbon atoms, and then adding p2 mol of ethylene oxide, wherein p1 is a number of from 3 to 30, q1 is a number of from 1 to 5, and p1+p2 is from 16 to 50, component (b): an anionic surfactant, component (c): a cationic surfactant, wherein the component (c) is a quaternary ammonium salt represented by the formula (c-1): wherein R R X represents a halogen atom, CH component (d): from 13 to 40% by mass of a water-miscible organic solvent.
