Abstract
Compositions of the present invention include an anionic surfactant, a zwitterionic surfactant, a superhydrophilic amphiphilic copolymer, an organic acid; and a polymer selected from the group consisting of a non-hydrophobically modified alkali-swellable emulsion polymer and a non-crosslinked hydrophobically modified acid-swellable emulsion polymer, wherein, when the composition contains the non-hydrophobically modified alkali-swellable emulsion polymer, the non-hydrophobically modified alkali-swellable emulsion polymer is present in an amount of about 0.1% to 5% by weight, and when the composition contains the non-crosslinked hydrophobically modified acid-swellable emulsion polymer, the non-hydrophobically modified acid-swellable emulsion polymer is present in an amount of about 0.1% to 5% by weight, and wherein the composition has an NTU value of 95 or less, a yield value of about 0.1 Pascal or more and pH of from about 3 to about 6.5.
