Abstract

An improved germicidal hard surface cleaning composition containing a quaternary ammonium germicide, detergent, builder salts and a binary solvent system comprising a saturated terpene hydrocarbon and a non-aqueous polar solvent is described. The binary system provides improved cleaning action for removal of greasy soil from porous and non-porous hard surfaces and does not interfere with the germicidal activity of the quaternary ammonium salt.

Claims

1. A clear, liquid, germicidal, hard surface cleaner consisting essentially of, by weight, a water-soluble, germicidal, quaternary ammonium salt having an alkyl group of 8 to 18 carbon atoms in its structure in an amount from the range of 2.5% to 6% which is effective to provide germicidal properties at a concentration of 1.5% by weight of said cleaner in water;

2% to 5% of a water-soluble ethyleneoxylated nonionic detergent;

from 1% to 8% of cis/trans 2,6,6 trimethylbicyclo (3.1.1) heptane;

from 1% to 8% of a nonaqueous, polar, organic solvent having water solubility at 25°

C. of at least 20% by weight selected from the group consisting of C₁ -C₄ alkyl ethers of ethylene glycol or diethylene glycol or mono-, di- or tripropylene glycol, from 2% to 6% of a water-soluble organic or inorganic alkaline builder salt;

the weight of said nonionic detergent being not greater than the weight of said quaternary salt; and

the balance primarily water.

2. A cleaner according to claim 1 wherein said quaternary ammonium salt includes an alkyl dimethyl benzyl ammonium salt selected from the group consisting of chloride, bromide and acetate.

3. A cleaner according to claim 2 wherein said quaternary ammonium salt further includes an alkyl dimethyl ethylbenzyl ammonium salt selected from the group consisting of chloride, bromide and acetate.

4. A cleaner according to claim 3 wherein the weight ratio of alkyl dimethyl benzyl ammonium salt to alkyl dimethyl ethylbenzyl ammonium salt is about 1:

1

5. A cleaner according to claim 2 wherein said nonaqueous solvent is said C₁ -C₄ alkyl ether of mono-, di- and tri-propylene glycol and said nonionic detergent is a condensate of a C₈ -C₁₈ alkanol with 5 to 30 moles of ethylene oxide.

6. A cleaner according to claim 5 wherein said builder is a mixture of sodium citrate dihydrate, sodium bicarbonate and sodium carbonate.

7. A cleaner according to claim 2 wherein said nonaqueous solvent is ethylene glycol monobutyl ether and said nonionic detergent is a condensate of a C₈ -C₁₈ alkanol with 5 to 30 moles of ethylene oxide.

8. A cleaner according to claim 7 wherein said builder is a mixture of sodium citrate dihydrate, sodium bicarbonate and sodium carbonate.

9. A cleaner according to claim 1 wherein said quaternary ammonium salt includes an alkyl dimethyl benzyl quaternary ammonium salt and is present in an amount of 3% to 4.5% by weight, said nonionic detergent is a condensate of a C₈ -C₁₈ alkanol with 5 to 30 moles of ethylene oxide;

said heptane is present in an amount of 1.5% to 4% by weight;

said nonaqueous solvent is present in an amount of 1.5% to 4% by weight; and

said builder salt is present in an amount of 3% to 5% by weight, with the weight ratio of builder salt to said quaternary salt being less than 1.25;

1.

10. A cleaner according to claim 9 wherein said nonaqueous solvent is said C₁ -C₄ alkyl ether of mono-, di- and tri-propylene glycol.

11. A cleaner according to claim 10 wherein said builder is a mixture of sodium citrate dihydrate, sodium bicarbonate and sodium carbonate.

12. A cleaner according to claim 9 wherein said nonaqueous solvent is ethylene glycol monobutyl ether.

13. A cleaner according to claim 12 wherein said builder is a mixture of sodium citrate dihydrate, sodium bicarbonate and sodium carbonate.
