Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
95 words
A liquid scouring cleaning composition consisting essentially of (a) from 30% to 60% by weight of cristobalite having a grain size of less than 150 μ and without a substantial proportion of particles having a grain size of less than 5 μ, (b) from 1% to 10% by weight of at least one non-ionic surface-active compound (c) from 0.1% to 2% by weight of a water-soluble polycarboxylate polymeric thickening agent, and (d) from 27% to 68.9% by weight of a predominantly aqueous liquid carrier, said liquid composition having a pH of between 9 and 11.
Claim 2
Dependent Claim
95 words
A liquid scouring cleaning composition consisting essentially of (a) from 30% to 60% by weight of cristobalite having a grain size of less than 150 μ and without a substantial proportion of particles having a grain size of less than 5 μ, (b) from 1% to 10% by weight of at least one non-ionic surface-active compound (c) from 0.1% to 2% by weight of a water-soluble polycarboxylate polymeric thickening agent, and (d) from 27% to 68.9% by weight of a predominantly aqueous liquid carrier, said liquid composition having a pH of between 9 and 11.
Claim 3
Dependent Claim
16 words
The liquid scouring cleaning composition of claim 1 wherein said predominantly aqueous liquid carrier is water.
Claim 4
Dependent Claim
58 words
The liquid scouring cleaning composition of claim 1 wherein said composition contains from 0.1 to 5% by weight of at least one conventional scouring cleaning composition additive of the following type: water-soluble inorganic bases, water-soluble organic bases, foam stabilizers, preservatives, antimicrobial agents, perfumes, dyes, water-soluble inorganic alkaline-reacting alkali metal salts, organic complex-forming acids and their alkali metal salts.
Claim 5
Dependent Claim
91 words
A liquid scouring agent composition consisting essentially of: (a) from 35% to 50% by weight of cristobalite having a grain size of less than 100 μ and over 5 μ, (b) from 1% to 6% by weight of at least one non-ionic surface-active compound, (c) from 0.1% to 1.5% by weight of a water-soluble polycarboxylate polymeric thickening agent, (d) from 40% to 63.9% by weight of water, and (e) from 0 to 20% by weight of a water-soluble organic solvent, said liquid composition having a pH of between 9 and 11.
Claim 6
Dependent Claim
91 words
A liquid scouring agent composition consisting essentially of: (a) from 35% to 50% by weight of cristobalite having a grain size of less than 100 μ and over 5 μ, (b) from 1% to 6% by weight of at least one non-ionic surface-active compound, (c) from 0.1% to 1.5% by weight of a water-soluble polycarboxylate polymeric thickening agent, (d) from 40% to 63.9% by weight of water, and (e) from 0 to 20% by weight of a water-soluble organic solvent, said liquid composition having a pH of between 9 and 11.
Claim 7
Dependent Claim
72 words
The liquid scouring cleaning composition of claim 4 wherein said water-soluble polycarboxylate polymeric thickening agent is a copolymer based on a monomeric acid selected from the group consisting of acrylic acid, methacrylic acid, and mixtures thereof, which contains, in addition to acryl and/or methacryl monomer units, from 25 mol percent to 75 mol percent of monomer units selected from the group consisting of lower alkyl acrylates, lower alkyl methacrylates, and mixtures thereof.
Claim 8
Dependent Claim
33 words
The liquid scouring cleaning composition of claim 4 wherein said water-soluble polycarboxylate polymeric thickening agent is a copolymer of acrylic acid containing from 0.2% to 2.5% by weight of polyallylpolysugar ether monomer units.
