Abstract:
1. A pourable, pumpable, high concentration, aqueous, liquid surfactant composition consisting of: (a) at least one surfactant selected from the group consisting of an amphoteric surfactant and an anionic surfactant; (b) at least about 0.1% by weight on a total composition weight basis of at least one liquid-stabilizing agent selected from the group consisting of a compound of formula (I) and a salt thereof; wherein A is —NH(R (c) optionally an alkali metal halide salt; and (d) water; wherein the surfactant is present in the high concentration, aqueous, liquid surfactant composition in a concentration of at least about 25% by weight, and the liquid-stabilizing agent is present in an amount of not more than about 10% by weight, on a total composition weight basis, and wherein the composition is non-liquid in the absence of the liquid stabilizing amount of the liquid stabilizing agent at an ambient temperature of about 20° C.
