Abstract

Abstract A stable, liquid detergent softening and brightening composition or concentrate contains a water-soluble non-ionic surfactant system; a quaternary ammonium softener having an equivalent weight from about 400 to 2000; at least an equivalent weight to said softener of a 4,4'-bis[4-disubstituted amino-6-(sulfosubstituted anilino)-s-triazin-2-ylamino]-2,2'-stilbene disulfonic acid optical brightener; a hydrotrope to stabilize the composition and an aqueous solvent medium therefor. The composition is storage stable and provides enhanced cling-free softening and brightening without loss of cleansing properties or yellowing of fabrics.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 300 words
An aqueous, stable, liquid detergent composition having enhanced softening and brightening properties comprising: (a) a water soluble non-ionic surfactant system having a relatively high cloud point in amounts from about 10 to 50% by weight, (b) a quaternary ammonium fabric softener having an equivalent weight from about 400 to 2000 in amounts from about 0.75 to 6% by weight of the formula: ##STR8## wherein Z is a water soluble, salt-forming anion, R 1 is a C 10 -C 20 alkyl radical, R 2 is R' or a C 10 -C 20 alkyl radical, X and Y are the same or different and are methyl, ethyl, 2-hydroxyethyl, 2-hydroxy propyl, --R"--C--C--O--H, or ##STR9## wherein R" is a polymer having from 1 to 10 ethoxy, isoproxy or mixed ethoxy-isopropoxy units, and R' is polyethoxy ethanol having from 1 to 10 ethoxy units only when: (i) X and Y are both methyl, or (ii) X is methyl and Y is polyethoxyethanol having from 1 to 10 ethoxy units, (iii) X is ethyl and Y is polyethoxy ethanol having from to 10 ethoxy units; (c) an optical brightener of the formula: ##STR10## wherein A and A 1 are the same or different and are hydrogen, methyl, ethyl, isopropyl, 2-hydroxyethyl, propanamido or taken together are morpholino or anilino; B is H, m-SO 3 H or p-SO 3 H wherein the total number of --SO 3 H groups is from 3 to 5, and the salts thereof having water soluble anions, wherein the equivalent weight ratio of (b) to (c) is from about 1/2:1 to 1:1, wherein the weights are based on the total weight of the aqueous composition; (d) a hydrotrope is sufficient amounts to maintain a stable composition; and (e) an aqueous solvent medium wherein said composition has a pH of from 6 to 10.
Claim 2
Dependent Claim 300 words
An aqueous, stable, liquid detergent composition having enhanced softening and brightening properties comprising: (a) a water soluble non-ionic surfactant system having a relatively high cloud point in amounts from about 10 to 50% by weight, (b) a quaternary ammonium fabric softener having an equivalent weight from about 400 to 2000 in amounts from about 0.75 to 6% by weight of the formula: ##STR8## wherein Z is a water soluble, salt-forming anion, R 1 is a C 10 -C 20 alkyl radical, R 2 is R' or a C 10 -C 20 alkyl radical, X and Y are the same or different and are methyl, ethyl, 2-hydroxyethyl, 2-hydroxy propyl, --R"--C--C--O--H, or ##STR9## wherein R" is a polymer having from 1 to 10 ethoxy, isoproxy or mixed ethoxy-isopropoxy units, and R' is polyethoxy ethanol having from 1 to 10 ethoxy units only when: (i) X and Y are both methyl, or (ii) X is methyl and Y is polyethoxyethanol having from 1 to 10 ethoxy units, (iii) X is ethyl and Y is polyethoxy ethanol having from to 10 ethoxy units; (c) an optical brightener of the formula: ##STR10## wherein A and A 1 are the same or different and are hydrogen, methyl, ethyl, isopropyl, 2-hydroxyethyl, propanamido or taken together are morpholino or anilino; B is H, m-SO 3 H or p-SO 3 H wherein the total number of --SO 3 H groups is from 3 to 5, and the salts thereof having water soluble anions, wherein the equivalent weight ratio of (b) to (c) is from about 1/2:1 to 1:1, wherein the weights are based on the total weight of the aqueous composition; (d) a hydrotrope is sufficient amounts to maintain a stable composition; and (e) an aqueous solvent medium wherein said composition has a pH of from 6 to 10.
Claim 3
Dependent Claim 30 words
The composition of claim 1 in which (d) is selected from a lower molecular weight alkaryl sodium sulfonate or an alkali salt of a C 8 -C 12 fatty acid.
Claim 4
Dependent Claim 30 words
The composition of claim 1 in which (a) is a blend of a water soluble ethylene oxide condensate of an alkyl phenol and an ethoxylated C 9 -C 11 alkanol.
Claim 5
Dependent Claim 20 words
The composition of claim 1 in which (b) is a dimethyl di (C 12 -C 18 ) alkyl ammonium salt.
Claim 6
Dependent Claim 17 words
