Abstract

A non-Newtonian concentrate composition includes a sensitizer or irritant, a surfactant, an anti-mist component and optionally a stability component. Example sensitizers and irritants include, but are not limited to, acids, quaternary compounds, and amines, and example anti-mist components include, but are not limited to, polyethylene oxide and polyacrylamide.

First claim

The following is claimed:

1. An aqueous concentrate composition, comprising
at least one fatty acid comprising hexanoic acid, butyric acid, octanoic acid, heptanoic acid, nonanoic acid, decanoic acid, undecanoic acid, dodecanoic acid, or a combination thereof, wherein the at least one fatty acid comprises from about 7% to about 45% by weight of the composition,
at least one surfactant, wherein the at least one surfactant comprises from about 0.1% to about 30% by weight of the composition, and
an anti-mist component comprising polyethylene oxide, polyacrylamide or a combination thereof, wherein the anti-mist component comprises from about 0.01% to about 0.3% by weight of the composition;
wherein the composition is non-Newtonian and comprises a viscosity of less than about 40 centipoise.

2. The composition of claim 1 , further comprising a stability component, wherein the stability component comprises from about 0.1% to about 10% by weight of the composition.

3. The composition of claim 2 , wherein the stability component comprises propylene glycol or glycerine.

4. The composition of claim 1 , wherein the composition comprises a pH of about 4.5 or lower.

5. The composition of claim 1 , further comprising a fragrance or dye.

6. The composition of claim 1 , comprising
about 7% to about 35% by weight of the at least one acid;
about 1.5% to about 12% by weight of the at least one surfactant;
about 0.01% to about 0.3% by weight of the anti-mist component; and
about 45% to about 75% by weight of water.

7. A non-Newtonian aqueous concentrate composition comprising:
a quaternary compound, wherein the quaternary compound comprises from about 5% to about 40% by weight of the composition, and
an anti-mist component comprising polyethylene oxide having a molecular weight of about 3,000,000 to about 7,000,000 daltons, wherein the anti-mist component constitutes from about 0.1% to about 0.3% by weight of the composition;
wherein the composition is non-Newtonian and comprises a viscosity of less than about 40 centipoise.

8. The composition of claim 7 , wherein the anti-mist component further comprises polyacrylamide.

9. The composition of claim 7 , further comprising from about 0.1% to 10% by weight of an antioxidant, chelant, or solvent.

10. The composition of claim 9 , wherein the solvent comprises propylene glycol or glycerine.

11. The composition of claim 7 , further comprising about 0.002% to about 1% by weight of a dye or fragrance.

12. The composition of claim 7 , further comprising about 7% to about 35% by weight of acid, wherein the acid comprises phosphoric acid, citric acid, lactic acid, or methane sulfonic acid.

13. The composition of claim 7 , further comprising about 7% to about 35% by weight of a fatty acid, wherein the fatty acid comprises hexanoic acid, butyric acid, octanoic acid, heptanoic acid, nonanoic acid, decanoic acid, undecanoic acid, dodecanoic acid, or a combination thereof.

14. The composition of claim 7 , further comprising a surfactant.

15. The composition of claim 7 , wherein the quaternary compound comprises a quaternary ammonium compound.

16. An aqueous concentrate composition comprising:
about 5% to about 40% by weight of a quaternary compound, and
about 0.5% to about 20% by weight of an anti-mist component comprises polyacrylate;
wherein the composition is non-Newtonian and comprises a viscosity of less than about 40 centipoise.

17. The composition of claim 16 , further comprising between about 0.1% and 10% of an antioxidant, chelant, or solvent.

18. The composition of claim 17 , wherein the solvent comprises propylene glycol or glycerine.

19. The composition of claim 16 , further comprising a dye or fragrance.

20. The composition of claim 16 , wherein the quaternary compound comprises a quaternary ammonium compound.

21. An aqueous concentrate composition, comprising:
about 7% to about 45% by weight of fatty acid, wherein the fatty acid comprises hexanoic acid, butyric acid, octanoic acid, heptanoic acid, nonanoic acid, decanoic acid, undecanoic acid, dodecanoic acid, or a combination thereof,
about 0.1% to about 30% by weight of surfactant; the aqueous concentrate composition, and
about 0.5% to about 20% by weight of an anti-mist component comprising polyacrylate;
wherein the composition is non-Newtonian and comprises a viscosity of less than about 40 centipoise.
