510/182, With aliphatic alcohol, ether, or ketone component510/181, Aqueous liquid composition510/400, With soil-release, anti-soiling, coating, or nonabrasive polishing component (e.g., with polysiloxane, chalk, etc.)510/427, With diverse non-soap surfactant510/434, Polycarboxylic acid component, or acid anhydride or salt thereof (e.g., acrylic acid polymer, maleic anhydride, sodium citrate, etc.)510/475, Synthetic polymer or natural rubber (other than polyether, such as polyethylene glycol, alkylene oxide condensation products, etc.)510/476, Carboxylic acid anhydride, free carboxyl group, or salt thereof in the polymer510/490Nitrogen attached indirectly to the carboxyl group by nonionic bonding, or salt thereof
Detergent compositions having good filming/streaking characteristics contain effective amounts of specific substantive materials to increase the hydrophilicity of the glass. Preferred formulas contain a amphoteric, including zwitterionic, and optionally, but preferably, anionic detergent surfactant at levels (e.g., from about 0.02 to about 15%); hydrophobic solvent; alkaline material, especially volatile alkaline materials comprising monoethanolamine or certain beta-amino-alkanol compounds; and salt of polycarboxylate, preferably polyacrylate, polymer at effective levels (e.g., from about 0.01% to about 10%, by weight of the composition).
