A concentrated liquid surfactant composition comprising; i) a surfactant package in an amount of from 0.2% to 98% by weight, based on the total weight of the surfactant composition; ii) a co-solvent in an amount of from greater than 0% to 95% by weight, based on the total weight of the surfactant composition, and, iii) a liquid polymer (LP) composition in an amount of from 0.1% to 60% by weight, based on the total weight of the surfactant composition; wherein the surfactant composition has a total water content of from 0.5% to 20% by weight, based on the total weight of the surfactant composition. The surfactant package may comprise a primary surfactant (which may be an anionic surfactant and furthermore may comprise a sulfonate, sulfate or carboxylate functional group) and one or more secondary surfactants. The liquid polymer composition may itself comprise; a) a hydrophobic liquid having a boiling point of at least 100oC; b) at least 39% by weight of a synthetic co-polymer (which may be an acrylamide co-polymer); c) an emulsifier surfactant, and, d) an inverting surfactant. A second aspect is directed towards a method of making a composition of the first aspect. |
