  • Use of sulfonated polystyrene polymers in hard surface cleaners to provide easier cleaning benefit
    Publication number: 20040194800
    Abstract: An aqueous hard surface cleaner composition contains a surfactant selected from the group consisting of nonionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants and mixtures thereof, a germicidal agent, which may be absent if the surfactant comprises a quaternary ammonium surfactant, a hydrophilic polymer comprising styrene sulfonate repeating units, and water, wherein the composition exhibits a pH of greater than or equal to about 6, and provides an easier cleaning benefit.
