Abstract
Abstract A liquid general-purpose cleaner, having improved non-streak and cleaning properties, is obtained if in a liquid-compatible medium which comprises a nonionic surfactant, an at least partially esterified resin and water or a mixture of water and a water-miscible organic solvent, as nonionic a topped nonionic surfactant is used containing less than 2% by weight of non-alkoxylated material and less than 4% by weight of mono-alkoxylated material. By using this nonionic surfactant, less partially esterified resin and less perfume are required to achieve effects similar to those obtained when a non-topped nonionic surfactant is used.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
143 words
A liquid general-purpose cleaning composition with improved non-streak and cleaning properties, comprising 0.01-98% by weight of a nonionic surfactant, 0 005-20% by weight of an at least partially esterified resin, derived from an unsaturated dicarboxylic acid or anhydride, and 1-99.91% by weight of a compatible liquid medium which consists of water or a mixture of water and one or more water-miscible organic solvents, the at least partially esterified resin being at least 5% esterified with a hydroxyl group-containing compound selected from the group consisting of aliphatic alcohols, glycol ethers and polyols, said compound not being a nonionic detergent surfactant, wherein the nonionic surfactant is a C 6 -C 18 primary or secondary, straight or branched chain alcohol condensed with 3-15 moles of alkylene oxide, and contains less than 2% by weight of non-alkoxylated alcohol and less than 4% by weight of mono-alkoxylated alcohol.

Claim 3
Dependent Claim
60 words
A composition according to claim 1, wherein the nonionic surfactant is selected from the group consisting of a C 11 -C 15 linear primary alcohol condensed with 7-11 moles of ethylene oxide, a C 9 -C 11 oxo-alcohol condensed with 5 moles of ethylene oxide, and a C 6 -10 linear primary alcohol condesed with 4.5 moles of ethylene oxide.
