Abstract
A nonionic surfactant based liquid laundry detergent formulation which consists essentially of between about 20 and about 30 percent by weight of one or more nonionic surfactants, between about 1 and 10 percent by weight of one or more of certain carboxysulfonate compounds which may be prepared, for example, by the direct reaction of a hydrocarbyl succinic anhydride with either an aminoalkyl sulfonate or a salt of isethionic acid, between about 2 and about 20 percent by weight of detergent builder, between about 2 and about 8 percent by weight of triethanol amine, and water. The formulation is very effective for removal of both particulate and oily soils from fabrics and for preventing their redeposition onto the fabrics during the wash. The formulations are further characterized as low-foaming and relatively insensitive to water hardness. The several components are highly compatible and can be formulated into stable, single-phase compositions, without the need for added hydrotropes and/or solubilizers.
