Abstract

An improved liquid detergent composition is comprised of: PA0 (a) from about 5 to 18% by weight of a mixture of longer chain alkyl polyglycol ethers; PA0 (b) from about 5 to 18% by weight of a second mixture of shorter chain alkyl polyglycol ethers, the quantitative ratio of component (a) to component (b) being from about 2:1 to 1:2; and PA0 (c) from about 2.5 to 10% by weight of a fabric-softening quaternary ammonium salt.
