    Patent number: 5990066
    Abstract: Liquid hard-surface cleaning compositions are disclosed which provide excellent gloss to the surfaces cleaned therewith. The compositions comprise a surfactant, a carboxylate-containing polymer, and a divalent counterion in a molar ratio of carboxylate-containing monomeric units in said polymer to said divalent counterion of from about 12:1 to 1:32.
    Type: Grant

    Inventors: Neil James Gordon, Vincent Reniers, Alan David Willey
  • Stable and clear concentrated cleaning compositions comprising at least one short chain surfactant
    Patent number: 5707948
    Abstract: Stable and clear concentrated cleaning compositions comprising at least one short chain surfactant, optionally in combination with long chain nonionic surfactant and potassium carbonate. The short chain surfactants allow for the formulation of stable compositions without the need for additional stabilizers and are especially effective in cleaning greasy soil; the potassium carbonate provides reduced filming and streaking, especially when an anionic sulfonate short chain surfactant is present.
