Abstract

Abstract Detergent compositions are disclosed which comprise, as a fabric softening ingredient, a fabric softening clay. The fabric softening clay is a hectorite of natural origin, having a layer change distribution such that at least 50% is in the range 0. 23-0. 31 The specified clays have excellent deposition and fabric softening properties.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 91 words
A detergent composition comprising at least 1% of a detersive surfactant, from 5% to 35% detergent builders, and from 1% to 25% of a hectorite clay of natural origin, said hectorite clay having the general formula : wherein Me III is Al, Fe, or B; or y = o; M n+ is a monovalent (n = I) or divalent (n =2) metal ion, said clay having a layer charge distribution (x+y) such that at least 50% of the layer charge is in the range of from 0. 23 to 0. 31.
Claim 2
Dependent Claim 91 words
A detergent composition comprising at least 1% of a detersive surfactant, from 5% to 35% detergent builders, and from 1% to 25% of a hectorite clay of natural origin, said hectorite clay having the general formula : wherein Me III is Al, Fe, or B; or y = o; M n+ is a monovalent (n = I) or divalent (n =2) metal ion, said clay having a layer charge distribution (x+y) such that at least 50% of the layer charge is in the range of from 0. 23 to 0. 31.
Claim 3
Dependent Claim 38 words
A detergent composition according to claim 1, wherein said hectorite clay has a distribution of layer charge (x+y) such that at least 65% of the layer charge is in the range of from 0. 23 to 0. 31.
Claim 4
Dependent Claim 49 words
A detergent composition containing from 1% to 25% of a hectorite clay of natural origin, said hectorite clay being characterized in that cotton terry towels laundered with a detergent composition containing 10% (weight) of the clay show a reduction of the shear hysteresis, 2HG5, of the at least 32%.
Claim 5
Dependent Claim 49 words
A detergent composition containing from 1% to 25% of a hectorite clay of natural origin, said hectorite clay being characterized in that cotton terry towels laundered with a detergent composition containing 10% (weight) of the clay show a reduction of the shear hysteresis, 2HG5, of the at least 32%.
Claim 6
Dependent Claim 24 words
A detergent composition according to claim 3, characterized in that the clay gives a reduction of the shear hysteresis parameter of at least 35%.
Claim 7
Dependent Claim 56 words
A detergent composition according to any one of the preceding claims further comprising, as an additional softening ingredient, from 1% to 10% of an amine of the formula R₁ R₂ R₃ N, wherein R₁ is C₆ to C₂₀ hydrocarbyl, R₂ is C₁ to C₂₀ hydrocarbyl, or hydrogen, and R₃ is C₁ to C₂₀ hydrocarbyl or hydrogen.
Claim 8
Dependent Claim 25 words
A detergent composition according to claim 5 wherein R₁ and R₂ are each alkyl having from 12 to 18 carbon atoms, and R₃ is methyl.
Claim 9
Dependent Claim 37 words
A detergent composition according to claim 6 wherein the amine is present in the form of a complex with a fatty acid of the formula R COOH, wherein R is a C₉ to C₂₀ alkyl or alkenyl.
Claim 10
Dependent Claim 58 words
A detergent composition according to claim 7 wherein the amine is present in the form of a complex with a phosphate ester of the formula wherein R₈ and R₉ are C₁-C₂₀ alkyl, or ethoxylated alkyl groups of the general formula alkyl-(OCH₂CH₂) y , wherein the alkyl substituent is C₁-C₂₀, and y is an integer of 1 to 15.
Claim 11
Dependent Claim 70 words
A detergent composition according to any one of the preceding claims further comprising from 1% to 10% of an amide of the formula R₁₀R₁₁NCOR₁₂, wherein R₁₀ and R₁₁ are independently selected from C₁-C₂₂ alkyl, alkenyl hydroxy alkyl, aryl, and alkyl-aryl groups; R₁₂ is hydrogen, or a C₁-C₂₂ alkyl or alkenyl, aryl or alkyl-aryl group, or is O-R₁₃, wherein R₁₃ is a C₁-C₂₂ alkyl or alkenyl, an aryl or alkyl-aryl group.
Claim 12
Dependent Claim 25 words
A detergent composition according to claim 9 wherein the amide is present in the form of a composite with the fatty acid of claim 7.
Claim 13
Dependent Claim 48 words
A detergent composition according to any one of the preceding claims, further comprising from 1% to 10% of a 1-(higher alkyl)amido (lower alkyl)-2-(higher alkyl)imidazoline, wherein higher alkyl is alkyl having from 12 to 22 carbon atoms, and lower alkyl is alkyl having from 1 to 4 carbon atoms.
Claim 14
Dependent Claim 73 words
A detergent composition according to any one of the preceding claims, further comprising from 5% to 35% of a builder system, said builder system comprising a) from 1% to 99% by weight of a tartrate monosuccinate component of the structure : wherein X is H or salt-forming cation; and b) from 1% to 99% by weight of a tartrate disuccinate component of the structure : wherein X is H or a salt-forming cation.
