Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 191 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 0.1 % 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 ; (d) 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 poly- hydroxy 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; wherein the total amount of cationic plus nonionic fabric conditioning agents is no more than about 11 % ;.and (e) water.
Claim 2
Dependent Claim 191 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 0.1 % 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 ; (d) 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 poly- hydroxy 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; wherein the total amount of cationic plus nonionic fabric conditioning agents is no more than about 11 % ;.and (e) water.
Claim 3
Dependent Claim 30 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);
Claim 4
Dependent Claim 32 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):
Claim 5
Dependent Claim 126 words
The liquid fabric conditioning composition of any of claims 1-3 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 di- polyethoxy monoalkyl amine having the structural formula where Egis 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 53 words
