Claim 0:
1. A concentrated liquid surfactant composition comprising:
(a) a surfactant package in an amount of from 0.2% to 98% by weight, based on the total weight of the concentrated liquid surfactant composition;
(b) a co-solvent in an amount of from greater than 0% to 95% by weight, based on the total weight of the concentrated liquid surfactant composition; and
(c) a liquid polymer (LP) composition in an amount of from 0.1% to 60% by weight, based on the total weight of the concentrated liquid surfactant composition;
wherein the surfactant composition comprises an alkyl aryl sulfonate surfactant;
wherein the concentrated liquid surfactant composition has a total water content of from 0.5% to 20% by weight, based on the total weight of the concentrated liquid surfactant composition;
wherein the concentrated liquid surfactant composition has a total additive concentration equal to the sum of the weight percent concentration of all surfactants and all co-solvents present in the concentrated liquid surfactant composition;
wherein the concentrated liquid surfactant composition has a total polymer concentration equal to the sum of the weight percent concentration of all polymers present in the concentrated liquid surfactant composition; and
wherein the weight ratio of the total additive concentration to the total polymer concentration is at least 1:1.
