Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
237 words
Liquid rinse-added fabric conditioning compositions comprising: a. from about 0.5 to about 50% by weight of a static control agent selected from the group consisting of water-soluble acid salts of diamine compounds of the formula ##STR7## wherein n ranges from 2 to 5; R 1 is an alkyl group containing from about 12 to 200 carbon atoms; and R 2 , R 3 and R 4 are each hydrogen or alkyl groups containing 1 to 20 carbon atoms, provided that at least two of R 2 , R 3 and R 4 are each hydrogen or alkyl containing from about 1 to about 3 carbon atoms, said salts having a solubility in water of at least 1 gram per liter at 25° C; b. from about 0.5% to about 20.0% by weight of a quaternary ammonium fabric softener selected from the group consisting of compounds of the formula ##STR8## wherein R 1 is an alkyl group containing from about 12 to 20 carbon atoms; R 2 is alkyl of about 1 to 20 carbon atoms, R 3 and R 4 are each alkyl of about 1 to 3 carbon atoms; X is a non-interfering anion; and m is 1 when X is monovalent and m is 2 when X is divalent; and c. from about 50 to 98% by weight of water; said composition having a pH value within the range of from about 3 to 9.
Claim 2
Dependent Claim
237 words
Liquid rinse-added fabric conditioning compositions comprising: a. from about 0.5 to about 50% by weight of a static control agent selected from the group consisting of water-soluble acid salts of diamine compounds of the formula ##STR7## wherein n ranges from 2 to 5; R 1 is an alkyl group containing from about 12 to 200 carbon atoms; and R 2 , R 3 and R 4 are each hydrogen or alkyl groups containing 1 to 20 carbon atoms, provided that at least two of R 2 , R 3 and R 4 are each hydrogen or alkyl containing from about 1 to about 3 carbon atoms, said salts having a solubility in water of at least 1 gram per liter at 25° C; b. from about 0.5% to about 20.0% by weight of a quaternary ammonium fabric softener selected from the group consisting of compounds of the formula ##STR8## wherein R 1 is an alkyl group containing from about 12 to 20 carbon atoms; R 2 is alkyl of about 1 to 20 carbon atoms, R 3 and R 4 are each alkyl of about 1 to 3 carbon atoms; X is a non-interfering anion; and m is 1 when X is monovalent and m is 2 when X is divalent; and c. from about 50 to 98% by weight of water; said composition having a pH value within the range of from about 3 to 9.
Claim 3
Dependent Claim
56 words
A composition according to claim 1 wherein the diamine salt static control agent comprises from about 1 to about 10% by weight of the composition; the quaternary ammonium fabric softener comprises from about 0.5 to about 8% by weight of the composition; and water comprises from about 85 to about 98% by weight of the composition.
Claim 4
Dependent Claim
60 words
A composition according to claim 1 A. wherein the diamine salt static control agent consists essentially of fully and partially acidified diamine acid salts derived from an acid selected from the group consisting of hydrochloric acid, acetic acid, sulfuric acid, sulfonic acid, formic acid and citric acid; and B. wherein the composition pH is maintained between about 5 and 7.
Claim 5
Dependent Claim
71 words
A composition according to claim 3 wherein for the diamine static control agent R 1 is alkyl from about 16 to about 18 carbon atoms; R 2 is hydrogen or alkyl from about 1 to about 2 carbon atoms; R 3 is hydrogen or alkyl from about 1 to about 2 carbon atoms; R 4 is hydrogen or alkyl from about 1 to about 2 carbon atoms; and n is 3.
Claim 6
Dependent Claim
65 words
A composition according to claim 4 wherein for the quaternary ammonium fabric softener R 1 is alkyl of from about 16 to about 18 carbon atoms; R 2 is alkyl from about 16 to about 18 carbon atoms; R 3 is alkyl of from about 1 to about 2 carbon atoms; and R 4 is alkyl of from about 1 to about 2 carbon atoms.
Claim 7
Dependent Claim
41 words
A composition according to claim 5 wherein the weight ratio of the diamine salt static control agent to quaternary ammonium fabric softener compound varies from about 1:1 to about 4:1, based on the weight of the diamine compound in unacidified form.
Claim 8
Dependent Claim
23 words
A composition according to claim 6 which additionally contains an opacifier in an amount sufficient to impart an opaque appearance to the composition.
Claim 9
Dependent Claim
55 words
A composition according to claim 1 which contains from about 0.1 to about 20% by weight of the composition of water-insoluble particulate sorbitan ester material selected from the group consisting of mono-, di-, tri-, and tetra-esters of sorbitan and mixtures thereof, said ester material having an average particle size between about 5 and 150 microns.
Claim 10
Dependent Claim
23 words
A composition according to claim 8 wherein the particulate sorbitan ester material is selected from mono- and di-esters of sorbitan and mixtures thereof.
Claim 11
Dependent Claim
40 words
A composition according to claim 9 wherein the sorbitan ester is selected from the group consisting of sorbitan monolaurate, sorbitan monomyristate, sorbitan monopalmitate, sorbitan monostearate, sorbitan monobehenate, sorbitan dilaurate, sorbitan dimyristate, sorbitan dipalmitate, sorbitan distearate, sorbitan dibehenate, and mixtures thereof.
Claim 12
Dependent Claim
