Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 172 words
A liquid fabric conditioning composition comprising (a) from about 2% to about 11% by weight of the composition of non-cyclic quaternary ammonium cationic fabric conditioning agent; (b) from about 1% to about 5% by weight of the composition of a nonionic fabric conditioning agent selected from the group consisting of: (i) C 10 -C 26 fatty acid esters of mono- or polyhydroxy alcohols containing 1 to 12 carbon atoms; and (ii) esters of fatty alcohols having from 12 to 24 carbon atoms in the alkyl chain and mono- or poly-carboxylic acids having from 1 to 8 carbon atoms in the alkyl chain; whereby the total number of carbon atoms in the ester is equal to or greater than 16; (c) from about 0.1% to about 1.3% by weight of the composition of protonated di-polyethoxy mono-alkyl amine; (d) from about 1% to about 6% by weight of the composition of a lower alcohol; and (e) water; wherein the total amount of cationic plus nonionic fabric conditioning agents is no more than about 11%.
Claim 2
Dependent Claim 172 words
A liquid fabric conditioning composition comprising (a) from about 2% to about 11% by weight of the composition of non-cyclic quaternary ammonium cationic fabric conditioning agent; (b) from about 1% to about 5% by weight of the composition of a nonionic fabric conditioning agent selected from the group consisting of: (i) C 10 -C 26 fatty acid esters of mono- or polyhydroxy alcohols containing 1 to 12 carbon atoms; and (ii) esters of fatty alcohols having from 12 to 24 carbon atoms in the alkyl chain and mono- or poly-carboxylic acids having from 1 to 8 carbon atoms in the alkyl chain; whereby the total number of carbon atoms in the ester is equal to or greater than 16; (c) from about 0.1% to about 1.3% by weight of the composition of protonated di-polyethoxy mono-alkyl amine; (d) from about 1% to about 6% by weight of the composition of a lower alcohol; and (e) water; wherein the total amount of cationic plus nonionic fabric conditioning agents is no more than about 11%.
Claim 3
Dependent Claim 31 words
The liquid fabric conditioning composition of claim 1 wherein the amount of protonated di-polyethoxy monoalkyl amine (A) bears the following relationship to the amount of nonionic fabric conditioning agent (N); (Wt.%A)≦0.2+(Wt.%N)/15.
Claim 4
Dependent Claim 33 words
The liquid fabric conditioning composition of claim 2 wherein the lower alcohol is ethylene glycol (G) and its amount bears the following relationship to the amount of protonated di-polyethoxy monoalkyl amine (A): (Wt.%G)≦4.5-2(Wt.%A).
Claim 5
Dependent Claim 128 words
The liquid fabric conditioning composition of any of claims 1, 2 or 3 wherein component (a) is from 3% to 8% by weight of the composition; wherein component (b) is from 0.3% to 1.0% by weight of the composition of protonated dipolyethoxy monoalkyl amine having the structural formula ##STR4## 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 6
Dependent Claim 54 words
The liquid fabric conditioning composition of any of claims 1, 2 or 3 wherein component (a) is ditallow dimethyl ammonium chloride; component (b) is protonated di-polyethoxy monoalkyl amine wherein R 9 is an alkyl group derived from tallow and (m+n) is from 20 to 23; and (c) is ethylene glycol, propylene glycol or ethanol.
Claim 7
Dependent Claim 60 words
The liquid fabric conditioning composition of any of claims 1, 2 or 3 wherein the nonionic fabric conditioning agent is selected from the group consisting of mono-, di-, and tri-esters of glycerol; mono- and di-esters of ethylene glycol; and esters of isobutanol; and wherein the number of carbon atoms in the fatty acid esterifying groups is from 12 to 18.
Claim 8
Independent Claim 62 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 any of claims 1, 2 or 3 in an amount sufficient to provide a concentration of fabric conditioner of about 2 ppm to about 200 ppm by weight of the rinsing bath; and (c) drying the fabrics.
