Abstract
Abstract Hard surface detergent compositions comprise nonionic detergent surfactant; tripropylene glycol or short chain alkyl ether of tripropylene glycol as a hydrophobic cleaning solvent; and optional, but preferred suds control system comprising fatty acid and anionic sulfonated and/or sulfated detergent surfactant. The compositions are preferably in the form of aqueous liquids and preferably have monoethanolamine and/or beta-aminoalkanol present. The compositions clean vinyl no-wax flooring without rinsing and without substantial filming/streaking.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
137 words
A hard surface detergent composition having good filming/streaking properties comprising: (a) detergent surfactant consisting essentially of from about 1% to about 15% of low sudsing nonionic detergent surfactant wherein said nonionic detergent surfactant is a fatty alcohol containing from about 8 to about 14 carbon atoms ethoxylated with from about 2 to about 10 moles of ethylene oxide per mole of fatty alcohol; (b) from about 0.5% to about 15% of hydrophobic solvent that provides a cleaning function selected from the group consisting of tripropylene glycol monomethyl ether, tripropylene glycol monobutyl ether, and mixtures thereof; and (c) from about 50% to about 97% water, the pH of said composition being from about 6 to about 12.5 and said composition containing less than about 1% inorganic crystallizable detergent builder material and less than about 1% anionic detergent surfactant.
Claim 2
Dependent Claim
137 words
A hard surface detergent composition having good filming/streaking properties comprising: (a) detergent surfactant consisting essentially of from about 1% to about 15% of low sudsing nonionic detergent surfactant wherein said nonionic detergent surfactant is a fatty alcohol containing from about 8 to about 14 carbon atoms ethoxylated with from about 2 to about 10 moles of ethylene oxide per mole of fatty alcohol; (b) from about 0.5% to about 15% of hydrophobic solvent that provides a cleaning function selected from the group consisting of tripropylene glycol monomethyl ether, tripropylene glycol monobutyl ether, and mixtures thereof; and (c) from about 50% to about 97% water, the pH of said composition being from about 6 to about 12.5 and said composition containing less than about 1% inorganic crystallizable detergent builder material and less than about 1% anionic detergent surfactant.
Claim 3
Dependent Claim

Claim 6
Dependent Claim
61 words
The composition of claim 1 wherein having an HLB of from about 7 to about 14, said composition additionally containing a suds control system comprising from about 0.01% to about 0.2% of fatty acid and from about 0.1% to about 1.0% of anionic detergent surfactant, the ratio of anionic detergent surfactant to fatty acid being from about 15:1 to about 5:1.
