Abstract
Abstract Thick and opaque general-purpose cleaning compositions having streak-free cleaning benefits are obtained by the use, in a composition comprising a nonionic detergent surfactant, an anionic detergent surfactant and an at least partially esterified resin, of a nonionic detergent surfactant with an HLB-value of between 3 and 10 and an anionic synthetic detergent in the form of its magnesium salt.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
93 words
An opaque liquid general-purpose cleaning composition having non-streak cleaning properties comprising (a) from 0.01-98% by weight of a nonionic detergent surfactant or mixture of nonionic surfactants having an HLB-value of between 3 to 10, (b) 0.005-20% by weight of an at least 5% alcohol esterified copolymer formed from an unsaturated monomer and an unsaturated dicarboxylic acid or -anhydride, (c) from 0.5-10% by weight of a magnesium salt of an anionic synthetic detergent, the balance being a compatible liquid medium consisting of water or mixtures of water and one or more water-miscible organic solvents.
Claim 2
Dependent Claim
93 words
An opaque liquid general-purpose cleaning composition having non-streak cleaning properties comprising (a) from 0.01-98% by weight of a nonionic detergent surfactant or mixture of nonionic surfactants having an HLB-value of between 3 to 10, (b) 0.005-20% by weight of an at least 5% alcohol esterified copolymer formed from an unsaturated monomer and an unsaturated dicarboxylic acid or -anhydride, (c) from 0.5-10% by weight of a magnesium salt of an anionic synthetic detergent, the balance being a compatible liquid medium consisting of water or mixtures of water and one or more water-miscible organic solvents.
Claim 3
Dependent Claim
22 words
A composition according to claim 1, wherein the nonionic or mixture of nonionic surfactants has an HLB-value of between 5 and 9.8.
Claim 4
Dependent Claim
35 words
A composition according to claim 1, wherein the magnesium salt is a magnesium salt of a C 10 -C 18 alkyl sulphate or C 10 -C 18 alkylether sulphate with 1-10 moles of ethylene oxide.
Claim 5
Dependent Claim
22 words
A composition according to claim 1, comprising from 1 to 7.5% by weight of the magnesium salt of the anionic synthetic detergent.
Claim 6
Dependent Claim
28 words
A composition according to claim 1, comprising 5-30% by weight of the nonionic detergent surfactant and 0.1-15% by weight of the at least 5% alcohol esterified resin copolymer.
Claim 7
Dependent Claim
28 words
A composition according to claim 5, comprising 5-25% by weight of the nonionic detergent surfactant and 0.5-10% by weight of the at least 5% alcohol esterified resin copolymer.
Claim 8
Dependent Claim
15 words
A composition according to claim 1, in which the esterification degree is at least 10%.
Claim 9
Dependent Claim
15 words
A composition according to claim 1, in which the esterification degree is at least 20%.
Claim 10
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 11
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 12
Dependent Claim
29 words
A composition according to claim 10, in which the at least 5% alcohol esterified resin copolymer is a copolymer of styrene with maleic anhydride, partially esterified with secondary butanol.
