Abstract:
1. A liquid detergent composition, comprising: a surfactant (A) [hereinafter, referred to as component (A)] in an amount of 40 to 80% by mass; a polymer compound (B) described below [hereinafter, referred to as component (B)] in an amount of 0.3 to 8% by mass; and water, wherein component (A) comprises a nonionic surfactant (a1) [hereinafter, referred to as component (a1)] represented by formula (1-1-2), (1-1-4), or (1-1-5) in an amount of 30 to 70% by mass of the composition: component (a1): a nonionic surfactant represented by formula (1-1-2), (1-1-4), or (1-1-5) R R R wherein, R 1 represents a hydrocarbon group having 8 to 22 carbon atoms; an oxygen-bonding carbon atom of R 1 in R 1 —O— is a primary carbon atom; A′O represents an oxypropylene group; m1 and m2 each represent an average addition mole number and m=m1+m2; m and n each represent an average addition mole number, m is a number of 16 to 30 and n is a number of 1 to 5; “•” represents that (A′O) and (EO) are linked randomly; component (B): a polymer compound having a polyether chain moiety (i) composed of polymerization units derived from an epoxide having 2 to 5 carbon atoms and a polymer chain moiety (ii) composed of polymerization units derived from one or more unsaturated carboxylic acid monomers selected from the group consisting of acrylic acid, methacrylic acid and maleic acid, the polymer compound having a graft structure wherein one of the chain moieties (i) and (ii) is the main chain and the other is a side chain.
