Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
51 words
A concentrated fabric softening composition comprising from about 0.01 to about 5% by weight of an antigelling agent selected from the group consisting of alkali metal nitrates and alkali metal nitrites, from about 8 to about 20% by weight of a cationic fabric softening agent, and the remainder being substantially water.
Claim 2
Dependent Claim
51 words
A concentrated fabric softening composition comprising from about 0.01 to about 5% by weight of an antigelling agent selected from the group consisting of alkali metal nitrates and alkali metal nitrites, from about 8 to about 20% by weight of a cationic fabric softening agent, and the remainder being substantially water.
Claim 3
Dependent Claim
23 words
The composition of claim 1 wherein the anti-gelling agent is sodium nitrate and is present from about 0.1 to about 1.5% by weight.
Claim 4
Dependent Claim
53 words
The composition of claim 1 wherein the anti-gelling agent is sodium nitrate and is present from about 0.15 to about 1.5% by weight, from about 15 to about 19% by weight of a cationic fabric softener selected from the group consisting of quaternary ammonium and imidazolinium salts, and the remainder is substantially water.
Claim 5
Dependent Claim
24 words
The composition of claim 1 formed by first dissolving the anti-gelling agent in water and subsequently adding the cationic fabric softener to the solution.
Claim 6
Dependent Claim
16 words
The composition of claim 1 having a viscosity of from about 100 to about 1,500 centipoises.
Claim 7
Dependent Claim
16 words
The composition of claim 5 having a viscosity of from about 200 to about 1,000 centipoises.
Claim 8
Dependent Claim
68 words
A process of softening fabrics comprising adding to the water in the rinse cycle of a washing machine a concentrated fabric softening composition comprising from about 0.01 to about 5% by weight of an anti-gelling agent selected from the group consisting of alkali metal nitrates and alkali metal nitrites, from about 8 to about 20% by weight of a cationic softening agent, and the remainder being substantially water.
Claim 9
Dependent Claim
68 words
A process of softening fabrics comprising adding to the water in the rinse cycle of a washing machine a concentrated fabric softening composition comprising from about 0.01 to about 5% by weight of an anti-gelling agent selected from the group consisting of alkali metal nitrates and alkali metal nitrites, from about 8 to about 20% by weight of a cationic softening agent, and the remainder being substantially water.
Claim 10
Dependent Claim
32 words
A method for preparing the composition of claim 1 which will not gel upon aging, comprising dissolving the anti-gelling agent in water and adding the cationic softner to said anti-gelling agent solution.
