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

1. 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, R₁ is a C₁₀ -C₂₀ alkyl radical, R₂ is R'"'"' or a C₁₀ -C₂₀ 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 A¹ 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-SO₃ H or p-SO₃ H wherein the total number of --SO₃ 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.

2. The composition of claim 1 in which (d) is selected from a lower molecular weight alkaryl sodium sulfonate or an alkali salt of a C₈ -C₁₂ fatty acid.

3. 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 C₉ -C₁₁ alkanol.

4. The composition of claim 1 in which (b) is a dimethyl di (C₁₂ -C₁₈) alkyl ammonium salt.

5. The composition of claim 1 in which (c) is a 4,4'"'"'-bis[4-diethanolamino-6-(p-sulfoanilino)-s-triazin-2-ylamino]-2,2'"'"'stilbenedisulfonic acid or a sodium salt thereof.
