Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
146 words
A detergent composition comprising from about 5 to about 99% by weight of an organic anionic, nonionic, ampholytic or zwitterionic detergent, or a mixture thereof, and from about 1 to about 50% by weight of the composition of an impalpable smectite clay having an ion-exchange capacity of at least about 50 meg/100 grams, in which clay from about 5 to about 100 molar percent of the exchangeable cations are alkyl-substituted ammonium ions of the general formula R 1 r 2 r 3 r 4 n + (1) wherein each of R 1 , R 2 , R 3 and R 4 represents an alkyl group having 1 to 4 carbon atoms or hydrogen, provided that the total number of carbon atoms does not exceed 8, and that not more than any two of R 1 , R 2 , R 3 and R 4 represent hydrogen.
Claim 2
Dependent Claim
146 words
A detergent composition comprising from about 5 to about 99% by weight of an organic anionic, nonionic, ampholytic or zwitterionic detergent, or a mixture thereof, and from about 1 to about 50% by weight of the composition of an impalpable smectite clay having an ion-exchange capacity of at least about 50 meg/100 grams, in which clay from about 5 to about 100 molar percent of the exchangeable cations are alkyl-substituted ammonium ions of the general formula R 1 r 2 r 3 r 4 n + (1) wherein each of R 1 , R 2 , R 3 and R 4 represents an alkyl group having 1 to 4 carbon atoms or hydrogen, provided that the total number of carbon atoms does not exceed 8, and that not more than any two of R 1 , R 2 , R 3 and R 4 represent hydrogen.
Claim 3
Dependent Claim
26 words
A composition according to claim 1, which comprises 2 to 30% by weight of a synthetic organic anionic, nonionic or zwitterionic detergent or a mixture thereof.
Claim 4
Dependent Claim
21 words
A composition according to claim 2, wherein not more than 80% by weight of the total organic detergent present is anionic.
Claim 5
Dependent Claim
20 words
A composition according to claim 3, wherein not more than 20% by weight of the organic detergent component is anionic.
Claim 6
Dependent Claim
35 words
A composition according to claim 1, wherein the organic detergent comprises predominantly one or more water-soluble soaps having 10-20 carbon atoms in the molecule, and constitutes from 10 to 60% by weight of the composition.
Claim 7
Dependent Claim
34 words
A composition according to claim 5 wherein the soaps are sodium and potassium soaps or mixtures thereof having 12 to 18 carbon atoms and constitute from 20 to 50% by weight of the composition.
Claim 8
Dependent Claim
20 words
A composition according to claim 5 which comprises from about 0.5 to about 20% by weight of a soap-curd dispersant.
Claim 9
Dependent Claim
21 words
A composition according to claim 7 which contains, as a curd dispersant, from 1 to 6% by weight of tallow monoethanolamide.
Claim 10
Dependent Claim
17 words
A composition according to claim 1 which contains from about 4 to about 25% of said clay.
Claim 11
Dependent Claim
19 words
A composition according to claim 9, which contains from about 5 to about 15% by weight of said clay.
Claim 12
Dependent Claim
16 words
A composition according to claim 9 wherein said clay is selected from montmorillonites, hectorites and saponites.
Claim 13
Dependent Claim
25 words
A composition according to claim 1 wherein from 10 to 40 molar percent of the exchangeable cations are alkyl-substituted ammonium ions of the formula (1).
Claim 14
Dependent Claim
18 words
A composition according to claim 1 in which the alkyl-substituted ammonium ions (1) are all tetra-alkyl ammonium ions.
Claim 15
Dependent Claim
24 words
A composition according to claim 13 wherein the alkyl-substituted ammonium ions are selected from the group consisting of tetramethylammonium and tetraethylammonium and mixtures thereof.
Claim 16
Dependent Claim
26 words
A composition according to claim 1 which also contains from about 5 to about 60% by weight of organic or inorganic detergency builder or mixtures thereof.
Claim 17
Dependent Claim
13 words
The composition of claim 2 wherein the organic detergent is a nonionic detergent.
Claim 18
Dependent Claim
20 words
