In one embodiment, the surfactant-polymer blend of the present invention comprises a) at least one amino acid surfactant and b) (i) an α, β-ethylenically unsaturated carboxylic acid monomer (ii) nonionic, At least one hydrophobically modified polymer polymerized from a monomer mixture comprising a copolymerizable α, β-ethylenically unsaturated monomer and (iii) an ethylenically unsaturated hydrophobic modified associative monomer. In other embodiments, the surfactant-polymer blend of the present invention comprises: a) at least one amino acid surfactant, and b) (i) an α, β-ethylenically unsaturated carboxylic acid monomer (ii) nonionic. At least one hydrophobically modified polymer formed from a mixture comprising a copolymerizable α, β-ethylenically unsaturated monomer and (iii) an ethylenically unsaturated hydrophobic modified associative monomer, and c) esterified with a fatty acid And at least one secondary thickener selected from selected alkoxylated methyl glucose ethers. |
