Abstract

Compositions and uses thereof to clean and/or rinse tableware, wherein the compositions include a sulfonated silane.

First claim

What is claimed is:

providing tableware; and
contacting the tableware with a composition comprising a zwitterionic sulfonated silane;

wherein the zwitterionic sulfonated silane has the following formula (Formula II):
(R 1 O) p —Si(Q 2 ) q -W—N + (R 2 )(R 3 )—(CH 2 ) m —SO 3 −    (II)

wherein:
each R 1 is independently a hydrogen, methyl group, or ethyl group;
each Q 2 is independently selected from hydroxyl, alkyl groups containing from 1 to 4 carbon atoms and alkoxy groups containing from 1 to 4 carbon atoms;
each R 2 and R 3 is independently a saturated or unsaturated, straight chain, branched, or cyclic organic group, which may be joined together, optionally with atoms of the group W, to form a ring;
W is an organic linking group;
p is an integer of 1 to 3;
m is an integer from 1 to 4;
q is 0 or 1; and
p+q=3.

2. The method of claim 1 wherein the zwitterionic sulfonated silane is

3. The method of claim 1 wherein providing tableware comprises providing dirty tableware, and contacting the dirty tableware comprises washing the dirty tableware.

4. The method of claim 3 wherein contacting the dirty tableware comprises washing the dirty tableware followed by rinsing the tableware to provide a protective layer.

5. The method of claim 1 wherein providing tableware comprises providing clean tableware, and contacting the tableware comprises rinsing the clean tableware to provide a protective layer.

6. The method of claim 1 wherein the composition further comprises a metal salt.

7. The method of claim 6 wherein the metal salt comprises a combination of a source of aluminum ion and a source of zinc ion.

8. The method of claim 7 wherein the composition further comprises a surfactant.

9. The method of claim 8 wherein the surfactant is a nonionic ethylene oxide containing surfactant.

10. The method of claim 1 wherein the composition further comprises a hydrophilic polymer.

11. The method of claim 10 wherein the hydrophilic polymer is a polycarboxylate.

12. The method of claim 1 wherein the composition further comprises an alkaline source.

13. The method of claim 12 wherein the alkaline source comprises a metal carbonate, an alkali metal hydroxide, or a combination thereof.

14. The method of claim 1 wherein the tableware is glassware.

15. The method of claim 1 wherein a dried coating of the composition on a substrate surface has a contact angle of less than 40 degrees.

16. A rinse-aid composition comprising:
a zwitterionic sulfonated silane;
a metal salt; and
a surfactant;

wherein the metal salt comprises at least one of a source of aluminum ion and a source of zinc ion.

17. The composition of claim 16 further comprising a hydrophilic polymer.

18. The composition of claim 17 wherein the hydrophilic polymer is a polycarboxylate.

19. The composition of claim 16 wherein a dried coating of the composition on a substrate surface has a contact angle of less than 40 degrees.

20. The composition of claim 19 wherein the zwitterionic sulfonated silane has the following formula (Formula II):
(R 1 O) p —Si(Q 2 ) q -W—N + (R 2 )(R 3 )—(CH 2 ) m —SO 3 −    (II)

wherein:
each R 1 is independently a hydrogen, methyl group, or ethyl group;
each Q 2 is independently selected from hydroxyl, alkyl groups containing from 1 to 4 carbon atoms and alkoxy groups containing from 1 to 4 carbon atoms;
each R 2 and R 4 is independently a saturated or unsaturated, straight chain, branched, or cyclic organic group, which may be joined together, optionally with atoms of the group W, to form a ring;
W is an organic linking group;
p and m are integers of 1 to 3;
q is 0 or 1; and
p+q=3.

21. The composition of claim 20 wherein the zwitterionic sulfonated silane is

22. The composition of claim 16 wherein the metal salt comprises a combination of a source of aluminum ion and a source of zinc ion.

23. The composition of claim 16 wherein the surfactant is a nonionic ethylene oxide containing surfactant.

24. The composition of claim 16 further comprising a nonpolymeric organic acid with one or more carboxylic acid moieties per molecule.

25. A solid rinse-aid composition comprising:
a zwitterionic sulfonated silane;
a surfactant; and
a solidification agent.

26. The composition of claim 25 further comprising a hydrophilic polymer.

27. The composition of claim 26 wherein the hydrophilic polymer is a polycarboxylate.

28. The composition of claim 25 wherein a dried coating of the composition on a substrate surface has a contact angle of less than 40 degrees.

29. The composition of claim 28 wherein the zwitterionic sulfonated silane has the following formula (Formula II):
