Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
134 words
A clear liquid hard surface cleaner consisting essentially of, by weight, from 2% to 8% of a water-soluble, synthetic anionic sulfated or sulfonated detergent salt having an alkyl group of 8 to 22 carbon atoms in the molecule; from 0.25% to 4% of a water-soluble ethyleneoxylated nonionic detergent; from 1% to 8% 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 15% of a water-soluble organic or inorganic alkaline builder salt; from 0.5% to 8% of a C 1 -C 3 alkyl-substituted benzene sulfonate hydrotrope salt; and the balance primarily water.
