Abstract

Abstract A liquid general-purpose cleaner, having improved non-streak and cleaning properties is obtained, if in a liquid compatible medium a nonionic surfactant and an at least partially esterified resin is included. The composition is substantially electrolyte-free, and can be applied to hard surfaces either in dilute form, or neat.A preferred partially esterified resin is a copolymer of styrene with maleic anhydride, partially esterified with isobutanol.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 36 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 and 1-99.985% of a compatible liquid medium.
Claim 2
Dependent Claim 36 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 and 1-99.985% of a compatible liquid medium.
Claim 3
Dependent Claim 30 words
A composition according to claim 1, comprising 5-30% by weight of the nonionic-surfactant, 0.1-15% by weight of the at least partially esterified resin and 50-97.9% of the compatible liquid medium.
Claim 4
Dependent Claim 33 words
A composition according to claim 1, comprising 7-25% by weight of the "nonionic surfactant, 0.5-10% by weight of the at least partially esterified resin and 55-92.5% by weight of the compatible liquid medium.
Claim 5
Dependent Claim 21 words
A composition according to claims 1-3, in which the nonionic surfactant has an HLB-value of between about 10 and about 15.
Claim 6
Dependent Claim 22 words
A composition according to claims 1-4, in which the at least partially esterified resin has an esterification degree of at least 5%.
Claim 7
Dependent Claim 15 words
A composition according to claim 5, in which the esterification degree is at least 10%.
Claim 8
Dependent Claim 15 words
A composition according to claims 5-6, in which the esterification degree is at least 20%.
Claim 9
Dependent Claim 28 words
A composition according to claims 1-7, in which the at least partially esterified resin is derived from an adduct of rosin and an unsaturated dicarboxylic acid or anhydride.
Claim 10
Dependent Claim 38 words
A composition according to claims 1-7, in which the at least partially esterified resin is derived from a copolymer of a mono-unsaturated aliphatic, cycloaliphatic or aromatic monomer having no carboxy groups, and an unsaturated dicarboxylic acid or anhydride.
Claim 11
Dependent Claim 26 words
A composition according to claim 9, in which the at least partially esterified resin is a copolymer of styrene with maleic anhydride, partially esterified with isobutanol.
Claim 12
Dependent Claim 14 words
A composition according to claims 1-10, containing no more than 5% of additional electrolytes.
Claim 13
Dependent Claim 12 words
A composition according to claims 1-11, substantially as described in the examples.
