Abstract

A liquid detergent composition comprising: PA0 (a) 5 to 50% by weight of a surfactant; PA0 (b) 1 to 30% by weight of a zeolite; and PA0 (c) 0.1 to 5% by weight of (i) a copolymer containing copolymerized components having the formulae (I) and (II) and a weight average molecular weight of 100,000 or more; or (ii) a copolymer containing the copolymerized components having the formulae (III), (IV), and (V): ##STR1## wherein R.sup.1 represents hydrogen or methyl, PA1 R.sup.2 represents hydrogen or methyl, PA1 R.sup.3 represents an alkyl group having 1 to 6 carbon atoms, PA1 R.sup.4 represents hydrogen or methyl, PA1 R.sup.5 represents hydrogen or methyl, PA1 R.sup.6 represents hydrogen or methyl, PA1 R.sup.7 represents methyl or ethyl, PA1 R.sup.8 represents an alkyl or alkenyl having 3 to 24 carbon atoms, PA1 M and M' represents hydrogen or a counter ion, and PA1 m/n is 2/8 to 7/3 (mol ratio). PA1 p/q is 2/8 to 8/2 (mol ratio) and r/(p+q+r)=1/50 to 20/50 (mol ratio).
