Abstract
The present invention relates to isotropic liquids in which hydrophobically modified polar polymers having much higher ratios of hydrophile:hydrophobe than previously possible can be incorporated into the compositions. The compositions comprise greater than 17% to 85% surfactant and rate of hydrophile to hydrophobe on the polymers is greater than 7:1, preferably greater than 20:1, preferably 25:1 and up and most preferably no upper limit.
