Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 92 words
A liquid fabric conditioning composition comprising (a) from about 3% to about 12% by weight of the composition of cationic fabric conditioning agent comprising (i) quaternary ammonium salt, and (ii) quaternary imidazolinium salt, wherein the weight ratio of (i):(ii) is from about 1:1.5 to about 4:1; (b) from about 0.2% to about 1.3% by weight of the composition of protonated di-polyethoxy monoalkyl amine; (c) from about 1% to about 6% by weight of the composition of a lower alcohol; and (d) water; wherein the pH is from about 3.5 to about 5.5.
Claim 2
Dependent Claim 92 words
A liquid fabric conditioning composition comprising (a) from about 3% to about 12% by weight of the composition of cationic fabric conditioning agent comprising (i) quaternary ammonium salt, and (ii) quaternary imidazolinium salt, wherein the weight ratio of (i):(ii) is from about 1:1.5 to about 4:1; (b) from about 0.2% to about 1.3% by weight of the composition of protonated di-polyethoxy monoalkyl amine; (c) from about 1% to about 6% by weight of the composition of a lower alcohol; and (d) water; wherein the pH is from about 3.5 to about 5.5.
Claim 3
Dependent Claim 133 words
The fabric conditioning composition of claim 1 wherein component (a) is from 4% to 8% by weight of the composition and the weight ratio of (i):(ii) is from 1.5:1 to 2.5:1; wherein component (b) is from 0.4% to 1.0% by weight of the composition of protonated dipolyethoxy monoalkyl amine having the structural formula ##STR5## where R is an alkyl group having from about 10 to about 20 carbon atoms and where (m+n) is from about 10 to about 40; and wherein component (c) is from 3% to 5% by weight of the composition and is selected from the group consisting of monohydroxy alkanes having from 1 to about 6 carbon atoms, dihydroxy alkanes having from 2 to about 8 carbon atoms, and glycol ethers having from about 4 to about 16 carbon atoms.
Claim 4
Dependent Claim 15 words
The fabric conditioning composition of claim 1 wherein the pH is from 4.0 to 4.8.
Claim 5
Dependent Claim 15 words
The fabric conditioning composition of claim 2 wherein the pH is from 4.0 to 4.8.
Claim 6
Dependent Claim 51 words
The fabric conditioning composition of claim 2, 3, or 4 wherein (i) is ditallow dimethyl ammonium chloride; (ii) is 2-tallow-1-methyl-1-(tallow amidoethyl) imidazoline methyl sulfate; (b) is protonated di-polyethoxy monoalkyl amine wherein R 9 is an alkyl group derived from tallow and (m+n) is equal to 23; and (c) is ethylene glycol.
Claim 7
Dependent Claim 70 words
The fabric conditioning composition of claim 4 wherein component (a) is 4.0% ditallow dimethyl ammonium chloride plus 2.1% 2-tallow-1-methyl-1-(tallow amidoethyl) imidazoline methyl sulfate by weight of the composition; component (b) is 0.5% by weight of the composition of protonated di-polyethoxy monoalkyl amine wherein R 9 is an alkyl group derived from tallow and (m+n) is equal to 23; and component (c) is 4.0% ethylene glycol by weight of the composition.
Claim 8
Dependent Claim 61 words
A method for conditioning fabrics comprising the steps of: (a) washing the fabrics; (b) rinsing the fabrics in an aqueous bath containing the composition of claim 1, 3 or 4 in an amount sufficient to provide a concentration of cationic fabric conditioner of about 2 ppm to about 200 ppm by weight of the rinsing bath; and (c) drying the fabrics.
Claim 9
Independent Claim 123 words
A method for conditioning fabrics comprising the steps of: (a) washing the fabrics; (b) rinsing the fabrics in an aqueous bath containing the composition hereinbelow defined in an amount sufficient to provide a concentration of cationic fabric conditioner of about 10 ppm to about 100 ppm by weight of the rinsing bath; and (c) drying the fabrics; wherein said composition comprises 4.0% ditallow dimethyl ammonium chloride; 2.1% 2-tallow-1-methyl-1-(tallow amidoethyl) imidazoline methyl sulfate; 0.5% protonated di-polyethoxy monoalkyl amine having the structure ##STR6## wherein R is an alkyl group derived from tallow and (m+n) is equal to 23; 4.0% ethylene glycol; and water; wherein all percentages are by weight based on the composition; and wherein the pH of the composition is from 4.0 to 4.8.
Claim 10
Independent Claim 123 words
A method for conditioning fabrics comprising the steps of: (a) washing the fabrics; (b) rinsing the fabrics in an aqueous bath containing the composition hereinbelow defined in an amount sufficient to provide a concentration of cationic fabric conditioner of about 10 ppm to about 100 ppm by weight of the rinsing bath; and (c) drying the fabrics; wherein said composition comprises 4.0% ditallow dimethyl ammonium chloride; 2.1% 2-tallow-1-methyl-1-(tallow amidoethyl) imidazoline methyl sulfate; 0.5% protonated di-polyethoxy monoalkyl amine having the structure ##STR6## wherein R is an alkyl group derived from tallow and (m+n) is equal to 23; 4.0% ethylene glycol; and water; wherein all percentages are by weight based on the composition; and wherein the pH of the composition is from 4.0 to 4.8.
