Abstract
Abstract A composition consisting essentially of surfactants, non-metal-crosslinked polymers, alkaline-reacting complexing agents, and a water-soluble organic solvent is suitable for preserving and cleaning hard surfaces, particularly floors. It is used in highly dilute form and leaves behind a hard, but readily redissolvable transparent protective film.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
153 words
A process for cleaning and preserving a floor surface consisting essentially of (1) wiping said floor surface with a 1 to 3% aqueous solution of a composition consisting essentially of: (a) from 0.5 to 10% by weight of a surfactant selected from the group consisting of adducts of ethylene oxide with alchols or alkylphenols, alkyl benzene sulfonates, alkyl sulfates, alkane sulfonates, fatty acid ester sulfonates and mixtures thereof; (b) from 0.1 to 4.5% by weight of an alkali-soluble, non-metal-crosslinked polymer compound having a minimum film-forming temperature of from 0° to 70° C.; (c) from 0.01 to 5% by weight of an alkaline-reacting complexing agent; (d) from 0 to 3% by weight of an alkalizing agent; (e) from 0 to 40% by weight of a water-miscible organic solvent; (f) from 0 to 5% by weight of additives; and (g) the remainder, water; and (2) allowing said aqueous solution to dry on said floor surface.
Claim 2
Dependent Claim
153 words
A process for cleaning and preserving a floor surface consisting essentially of (1) wiping said floor surface with a 1 to 3% aqueous solution of a composition consisting essentially of: (a) from 0.5 to 10% by weight of a surfactant selected from the group consisting of adducts of ethylene oxide with alchols or alkylphenols, alkyl benzene sulfonates, alkyl sulfates, alkane sulfonates, fatty acid ester sulfonates and mixtures thereof; (b) from 0.1 to 4.5% by weight of an alkali-soluble, non-metal-crosslinked polymer compound having a minimum film-forming temperature of from 0° to 70° C.; (c) from 0.01 to 5% by weight of an alkaline-reacting complexing agent; (d) from 0 to 3% by weight of an alkalizing agent; (e) from 0 to 40% by weight of a water-miscible organic solvent; (f) from 0 to 5% by weight of additives; and (g) the remainder, water; and (2) allowing said aqueous solution to dry on said floor surface.
Claim 3
Dependent Claim
123 words
A process in accordance with claim 1 wherein said composition consists essentially of: (a) from 1 to 6% by weight of a surfactant selected from the group consisting of adducts of ethylene oxide with alcohols or alkylphenols, alkylbenzene sulfonates, alkyl sulfates, alkane sulfonates, fatty acid ester sulfonates and mixtures thereof; (b) from 0.2 to 2.0% by weight of an alkali-soluble, non-metal-crosslinked polymer compound having a minimum film-forming temperature of from 0° to 70° C.; (c) from 0.05 to 3% by weight of an alkaline-reacting complexing agent; (d) from 0.05 to 2% by weight of an alkalizing agent; (e) from 0 to 20% by weight of a water-miscible organic solvent; (f) from 0.05 to 2% by weight of additives; and (g) the remainder, water.
