Abstract

The present invention is directed to rinse aid compositions and methods for making and using the rinse aid compositions. The compositions of the invention include a sheeting agent, a defoaming agent, and an association disruption agent. The rinse aid compositions of the present invention result in a faster draining/drying time on most substrates compared to conventional rinse aids. The rinse aid compositions of the present invention are especially suitable for use on plastic substrates.

Claims (45)

1. A solid rinse aid composition comprising:

(a) a sheeting agent, wherein the sheeting agent comprises at least one compound having the structure represented by formula I: R—O—(CH 2 CH 2 O) n —H wherein R is a (C 1 -C 12 ) alkyl group, and n is an integer in the range of 21 to 100;

(b) a defoaming agent;

(c) an association disruption agent of an alcohol alkoxylate EO/PO surfactant, and/or a C 12 -C 14 fatty alcohol EO/PO surfactant;

(e) a chelating agent

(f) an acid source; and

(g) an anti-microbial.

2. The rinse aid of claim 1 wherein said chelating agent is a polymeric polycarboxylate.

3. The rinse aid of claim 1 wherein said polymeric polycarboxylate is one or more of the following: a polyacrylic acid, maleic/olefin copolymer, acrylic/maleic copolymer, polymethacrylic acid, acrylic acid-methacrylic acid copolymers, hydrolyzed polyacrylamide, hydrolyzed polymethacrylamide, hydrolyzed polyamide-methacrylamide copolymers, hydrolyzed polyacrylonitrile, hydrolyzed polymethacrylonitrile, hydrolyzed acrylonitrile-methacrylonitrile copolymers.

4. The rinse aid of claim 3 wherein said polymeric polycarboxylate is a polyacrylic acid or polyacrylate.

5. The rinse aid of claim 1 wherein said anti-microbial includes one or more of a phenolic, a halogen compound, a quaternary ammonium compound, a metal derivative, an amine, an alkanol amine, a nitro derivative, an analide, an organosulfur and a sulfur-nitrogen compound.

6. The rinse aid of claim 5 wherein said anti-microbial is an organosulfur or sulfur nitrogen compound.

7. The rinse aid of claim 1 further comprising a hydrotope.

8. The rinse aid of claim 1 further comprising xylene sulfonate.

9. The rinse aid of claim 1 further comprising a hardening agent.

10. A solid rinse aid composition comprising:

(a) a sheeting agent, wherein the sheeting agent comprises at least one compound having the structure represented by formula I: R—O—(CH 2 CH 2 O) n —H wherein R is a (C 1 -C 12 ) alkyl group, and n is an integer in the range of 21 to 100;

(b) a defoaming agent;

(c) an association disruption agent of an alcohol alkoxylate EO/PO surfactant, and/or a C 12 -C 14 fatty alcohol EO/PO surfactant;

(d) a polyacrylic acid homopolymer or alkali metal salt thereof;

(e) an acid source;

(f) a chelating agent; and

(g) an anti-microbial.

11. The rinse aid of claim 10 wherein said chelating agent is a polymeric polycarboxylate.

12. The rinse aid of claim 11 wherein said polymeric polycarboxylate is one or more of the following: a polyacrylic acid, maleic/olefin copolymer, acrylic/maleic copolymer, polymethacrylic acid, acrylic acid-methacrylic acid copolymers, hydrolyzed polyacrylamide, hydrolyzed polymethacrylamide, hydrolyzed polyamide-methacrylamide copolymers, hydrolyzed polyacrylonitrile, hydrolyzed polymethacrylonitrile, hydrolyzed acrylonitrile-methacrylonitrile copolymers.

13. The rinse aid of claim 12 wherein said polymeric polycarboxylate is a polyacrylic acid or polyacrylate.

14. The rinse aid of claim 10 wherein said anti-microbial includes one or more of a phenolic, a halogen compound, a quaternary ammonium compound, a metal derivative, an amine, an alkanol amine, a nitro derivative, an analide, an organosulfur and a sulfur-nitrogen compound.

15. The rinse aid of claim 11 wherein said anti-microbial is an organosulfur or sulfur nitrogen compound.

16. The rinse aid of claim 10 further comprising a hydrotope.

17. The rinse aid of claim 10 further comprising xylene sulfonate.

18. The rinse aid of claim 10 further comprising a hardening agent.

19. A solid rinse aid composition comprising:

(a) a sheeting agent, wherein the sheeting agent comprises at least one compound having the structure represented by formula I: R—O—(CH 2 CH 2 O) n —H wherein R is a (C 1 -C 12 ) alkyl group, and n is an integer in the range of 21 to 100;

(b) a defoaming agent;

(c) a polyacrylic acid homopolymer or alkali metal salt thereof;

(d) an acid source; and

(e) an anti-microbial.

20. The rinse aid of claim 19 further comprising a chelating agent polymeric polycarboxylate.

21. The rinse aid of claim 20 wherein said polymeric polycarboxylate is one or more of the following: a polyacrylic acid, maleic/olefin copolymer, acrylic/maleic copolymer, polymethacrylic acid, acrylic acid-methacrylic acid copolymers, hydrolyzed polyacrylamide, hydrolyzed polymethacrylamide, hydrolyzed polyamide-methacrylamide copolymers, hydrolyzed polyacrylonitrile, hydrolyzed polymethacrylonitrile, hydrolyzed acrylonitrile-methacrylonitrile copolymers.

22. The rinse aid of claim 21 wherein said polymeric polycarboxylate is a polyacrylic acid or polyacrylate.

23. The rinse aid of claim 19 wherein said anti-microbial includes one or more of a phenolic, a halogen compound, a quaternary ammonium compound, a metal derivative, an amine, an alkanol amine, a nitro derivative, an analide, an organosulfur and a sulfur-nitrogen compound.

24. The rinse aid of claim 23 wherein said anti-microbial is an organosulfur or sulfur nitrogen compound.

25. The rinse aid of claim 19 further comprising a hydrotope.

26. The rinse aid of claim 19 further comprising xylene sulfonate.

27. The rinse aid of claim 19 further comprising a hardening agent.
