Abstract
The present invention relates to isotropic liquids containing anionic polymers wherein the polymers are not hydrophobically modified and can still be incorporated into the compositions. By using anionic/nonionic compositions in which more than 25% of nonionic is sugar surfactant, the polymers can be incorporated without such modification.
