Abstract
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 Analysis
Total Claims: 14
Claim 1
Independent Claim
159 words
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 C 1 -C 4 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.
Claim 2
Dependent Claim
159 words
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 C 1 -C 4 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.
Claim 3
Dependent Claim
