Abstract

Abstract A liquid general-purpose cleaner, having improved nonstreak and cleaning properties is obtained by inclusion, in a liquid compatible medium, of an at least 5% alcohol esterified resin copolymer and a nonionic surfactant having an HLB-value of between 10 and 15. The composition contains generally less than 5% of inorganic electrolyte salts, and can be applied to hard surfaces either in dilute form or neat.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 61 words
A liquid general-purpose cleaning composition with improved non-streak and cleaning properties, comprising: (a) 0.01-98% by weight of a nonionic surfactant, having an HLB-value of between 10 and 15, (b) 0.005-20% by weight of an at least 5% alcohol esterified resin copolymer formed from an unsaturated monomer and an unsaturated dicarboxylic acid or anhydride, and (c) 1-99.985% of a compatible liquid medium.
Claim 2
Dependent Claim 61 words
A liquid general-purpose cleaning composition with improved non-streak and cleaning properties, comprising: (a) 0.01-98% by weight of a nonionic surfactant, having an HLB-value of between 10 and 15, (b) 0.005-20% by weight of an at least 5% alcohol esterified resin copolymer formed from an unsaturated monomer and an unsaturated dicarboxylic acid or anhydride, and (c) 1-99.985% of a compatible liquid medium.
Claim 3
Dependent Claim 33 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 5% alcohol esterified resin copolymer and 50-97.9% of the compatible liquid medium.
Claim 4
Dependent Claim 35 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 5% alcohol esterified resin copolymer and 55-92.5% by weight of the compatible liquid medium.
Claim 5
Dependent Claim 15 words
A composition according to claim 1, in which the esterification degree is at least 10%.
Claim 6
Dependent Claim 15 words
A composition according to claim 1, in which the esterification degree is at least 20%.
Claim 7
Dependent Claim 30 words
A composition according to claim 1, in which the at least 5% alcohol esterified resin copolymer is derived from an adduct of rosin and an unsaturated dicarboxylic acid or anhydride.
Claim 8
Dependent Claim 40 words
A composition according to claim 1, in which the at least 5% alcohol esterified resin copolymer 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 9
Dependent Claim 29 words
A composition according to claim 7, in which the at least 5% alcohol esterified resin copolymer is a copolymer of styrene with maleic anhydride, partially esterified with secondary butanol.
Claim 10
Dependent Claim 25 words
A composition according to claim 1, comprising apart from the essential ingredients listed in claim 1 no more than 5% of additional inorganic electrolyte salts.
