Claims37
A method for cleaning a surface comprising:
- a. providing an absorbent or adsorbent material, said absorbent or adsorbent material including a material selected from the group consisting of wood pulp, wood pulp derivative, synthetic fibers, and mixtures thereof;
- b. at least partially exposing said absorbent or adsorbent material with an improved cleaning composition, said improved cleaning composition including a cationic biocide and a surfactant, said cationic biocide including a compound selected from the group consisting of biguanide compound, quaternary ammonium compound or mixtures thereof, said improved cleaning composition including 0.25-2 weight percent quaternary ammonium compound, biguanide or combinations thereof, 0.1-5 weight percent alcohol containing solvent, 0-2 weight percent non-alcohol containing solvent, 0.1-3 weight percent surfactant containing alkyl polyglycoside, amine oxide, or combinations thereof, 0-0.5 weight percent builder detergent, 0.05-5 weight percent copolymer of vinylpyrrolidone and dimethylaminoethylmethacrylate quaternized with diethylsulfate, 0.1-2 weight percent biocide release agent, and at least 10 weight percent water, and;
- c. contacting said surface with said absorbent or adsorbent material and said improved cleaning composition to cause over 50% of the cationic biocide to be released from said absorbent or adsorbent material.
A method for cleaning a surface comprising:
- a. providing an absorbent or adsorbent material, said absorbent or adsorbent material including a material selected from the group consisting of wood pulp, wood pulp derivative, synthetic fibers, and mixtures thereof;
- b. at least partially exposing said absorbent or adsorbent material with an improved cleaning composition, said improved cleaning composition including 0.25-2 weight percent quaternary ammonium compound, biguanide or combinations thereof, 0.1-5 weight percent alcohol containing solvent, 0-2 weight percent non-alcohol containing solvent, 0.1-3 weight percent surfactant containing alkyl polyglycoside, amine oxide, or combinations thereof, 0-0.5 weight percent builder detergent, 0.05-5 weight percent copolymer of vinylpyrrolidone and dimethylaminoethylmethacrylate quaternized with diethylsulfate, 0.1-2 weight percent biocide release agent, and at least 10 weight percent water;
- c. and contacting said hard surface with said absorbent or adsorbent material and said improved cleaning composition.
A method for cleaning a surface comprising:
- a. providing an absorbent or adsorbent material, said absorbent or adsorbent material including a material selected from the group consisting of wood pulp, wood pulp derivative, synthetic fibers, and mixtures thereof;
- b. at least partially exposing said absorbent or adsorbent material with an improved cleaning composition, said improved cleaning composition including 0.25-2 weight percent quaternary ammonium compound, biguanide or combinations thereof, 0.1-5 weight percent alcohol containing solvent, 0-2 weight percent non-alcohol containing solvent, 0.1-3 weight percent surfactant containing alkyl polyglycoside, amine oxide, or combinations thereof, 0-0.5 weight percent builder detergent, 0.05-5 weight percent copolymer of vinylpyrrolidone and dimethylaminoethylmethacrylate quaternized with diethylsulfate, 0.1-2 weight percent biocide release agent, and at least 10 weight percent water, said alcohol containing solvent has a boiling point of less than about 150° C. and said non-alcohol containing solvent has a boiling point of at least about 150° C. a weight ratio of said alcohol containing solvent to said non-alcohol containing solvent is about 10-1:1 c. and contacting said hard surface with said absorbent or adsorbent material and said improved cleaning composition.
