Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
202 words
An aqueous built liquid detergent composition, consisting essentially of: (a) 5-15% by weight of an anionic synthetic detergent selected from the group consisting of C 10 -C 24 alkylbenzene sulphonates, C 10 -C 24 alkane sulphonates and C 10 -C 24 alkylether sulphates containing 1-10 moles of ethylene- or propylene oxide; (b) 1-5% by weight of a nonionic synthetic detergent selected from a group consisting of adducts of 5-30 moles of an alkylene oxide to C 10 -C 24 primary alcohols, C 10 -C 24 secondary alcohols, and C 9 -C 18 alkylphenols; (c) 1-5% by weight of a sodium or potassium salt of dimerized oleic acid; (d) 1-25% by weight of a sodium or potassium builder salt selected from the group consisting of orthophosphates, pyrophosphates, tripolyphosphates, carbonates and mixtures thereof; (e) 0.75-8.5% by weight of an alkali metal or ammonium salt of xylene-, toluene- or cumene sulphonic acid; (f) 0.5-2.5% by weight of a monoalkane phosphonic acid, in which the alkane group contains 4-10 carbon atoms, or the alkali metal or ammonium salt thereof, whereby the amount of salt of xylene sulphonic acid is more than 4% by weight when the amount of the monoalkane phosphonic acid is 1% or less.

Dependent Claim

An aqueous built liquid detergent composition, consisting essentially of: (a) 5-15% by weight of an anionic synthetic detergent selected from the group consisting of C 10 -C 24 alkylbenzene sulphonates, C 10 -C 24 alkane sulphonates and C 10 -C 24 alkylether sulphates containing 1-10 moles of ethylene- or propylene oxide; (b) 1-5% by weight of a nonionic synthetic detergent selected from a group consisting of adducts of 5-30 moles of an alkylene oxide to C 10 -C 24 primary alcohols, C 10 -C 24 secondary alcohols, and C 9 -C 18 alkylphenols; (c) 1-5% by weight of a sodium or potassium salt of dimerized oleic acid; (d) 1-25% by weight of a sodium or potassium builder salt selected from the group consisting of orthophosphates, pyrophosphates, tripolyphosphates, carbonates and mixtures thereof; (e) 0.75-8.5% by weight of an alkali metal or ammonium salt of xylene-, toluene- or cumene sulphonic acid; (f) 0.5-2.5% by weight of a monoalkane phosphonic acid, in which the alkane group contains 4-10 carbon atoms, or the alkali metal or ammonium salt thereof, whereby the amount of salt of xylene sulphonic acid is more than 4% by weight when the amount of the monoalkane phosphonic acid is 1% or less.

A composition according to claim 1, further comprising 0.5-5% by weight of a sodium or potassium polyacrylate with a molecular weight of 3,500-22,000.
Claim 4
Dependent Claim
15 words
A composition according to claim 1, wherein the monoalkane phosphonic acid is monooctane phosphonic acid.
