Liquid detergent composition

Claim 1

A liquid, stable, concentrated, essentially homogeneous heavy duty detergent composition consisting essentially of: (1) from about 35% to about 65% by weight of a mixture of: (A) a nonionic surfactant having the formula R.sub.1 O--(C.sub.2 H.sub.4 O).sub.x --H wherein R 1 represents a hydrocarbyl group derived from a primary hydrocarbon monohydric alcohol of at least 70% branched-chain structure having from about 16 to about 19 carbon atoms, and x is a number of from about 9 to about 13; (B) a nonionic surfactant having the formula R.sub.2 O--(C.sub.2 H.sub.4 O).sub.y --H wherein R 2 is a hydrocarbyl group derived from a primary or secondary, straight or branched aliphatic alcohol of at least 40% branched-chain structure having from about 12 to about 15 carbon atoms, and y is a number from about 3 to about 6; wherein the weight ratio of (A) to (B) is from about 5:1 to about 2:1; (C) a triethanolamine salt of an alkylbenzene sulfonic acid having on average about 12 carbon atoms in the alkyl group; wherein the weight ratio of (A) + (B) to (C) is from about 4:1 to about 2:1; (2) from about 3% to about 15% by weight of a liquid organic carrier selected from the group consisting of: ethanol; n-propanol; iso-propanol; alkali-metal salts and ethanolamine salts of cumene sulfonic acid; and mixtures thereof; (3) a silicone suds-controlling agent in an amount from 0.01% to 0.2% by weight; and (4) water.
