Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
140 words
An environmentally compatible and biodegradable fabric conditioning composition capable of providing improved softening with significant reduction and solubilization of unwanted mineral encrustations on fabrics to be softened, such encrustations having generally deposited on the fabrics during the course of laundering in water having a high mineral content, which comprises a fabric conditioning mixture of: (a) from about 1 to 20% by weight of (i) an alkanolamine diester having the general formula: ##STR3## and (ii) an alkanolamine triester having the general formula: ##STR4## wherein R 1 , R 2 , R 3 are each independently hydrogenated tallow or soft tallow; and n, m, and p are integers from 1 to 4; and (b) from about 5 to 25% by weight an acid selected from the group consisting of citric acid, formic acid, maleic acid, malonic acid, tartaric acid and succinic acid.
Claim 2
Dependent Claim
140 words
An environmentally compatible and biodegradable fabric conditioning composition capable of providing improved softening with significant reduction and solubilization of unwanted mineral encrustations on fabrics to be softened, such encrustations having generally deposited on the fabrics during the course of laundering in water having a high mineral content, which comprises a fabric conditioning mixture of: (a) from about 1 to 20% by weight of (i) an alkanolamine diester having the general formula: ##STR3## and (ii) an alkanolamine triester having the general formula: ##STR4## wherein R 1 , R 2 , R 3 are each independently hydrogenated tallow or soft tallow; and n, m, and p are integers from 1 to 4; and (b) from about 5 to 25% by weight an acid selected from the group consisting of citric acid, formic acid, maleic acid, malonic acid, tartaric acid and succinic acid.
Claim 3
Dependent Claim
32 words
A fabric conditioning composition according to claim 1 wherein in the general formula R 1 , R 2 and R 3 are each hydrogenated tallow, and n, m and p are 2.
Claim 4
Dependent Claim
14 words
A fabric conditioning composition according to claim 1 wherein the acid is citric acid.
Claim 5
Dependent Claim
16 words

Dependent Claim
19 words
A fabric conditioning composition according to claim 5 wherein the fatty alcohol is a C 16 -C 18 alcohol.
Claim 8
Independent Claim
125 words
A method for softening and removing unwanted mineral encrustations therefrom comprising rinsing the fabrics to be treated in an aqueous bath containing an effective amount of a rinse cycle fabric conditioning composition comprising a fabric conditioning mixture of: (a) from about 1 to 20% by weight of (i) an alkanolamine diester having the general formula: ##STR5## and (ii) an alkanolamine triester having the general formula: ##STR6## and, wherein R 1 , R 2 , R 3 are each independently hydrogenated tallow or soft tallow; and n, m, and p are integers from 1 to 4; and (b) from about 5 to 25% by weight an acid selected from the group consisting of citric acid, formic acid, maleic acid, malonic acid, tartaric acid and succinic acid.
Claim 9
Independent Claim
125 words
A method for softening and removing unwanted mineral encrustations therefrom comprising rinsing the fabrics to be treated in an aqueous bath containing an effective amount of a rinse cycle fabric conditioning composition comprising a fabric conditioning mixture of: (a) from about 1 to 20% by weight of (i) an alkanolamine diester having the general formula: ##STR5## and (ii) an alkanolamine triester having the general formula: ##STR6## and, wherein R 1 , R 2 , R 3 are each independently hydrogenated tallow or soft tallow; and n, m, and p are integers from 1 to 4; and (b) from about 5 to 25% by weight an acid selected from the group consisting of citric acid, formic acid, maleic acid, malonic acid, tartaric acid and succinic acid.
