Abstract

Floor finishes are stripped or deep scrubbed using a floor stripper/cleaner composition containing sparingly water-soluble floor finish solvent; water; sulfonic acid, sulfate acid, phosphonic acid, phosphate acid or aromatic acid coupler in an amount sufficient to provide a homogenous aqueous liquid phase and no or low foaming during shaking; and sufficient organic amine so that the composition pH is about 2 to about 11.

Claims (30)

1. A floor finish stripper or scrub and recoat composition comprising:

a) sparingly water-soluble floor finish solvent;

b) water;

c) nonethoxylated coupler consisting of toluene, xylene, or cumene sulfonic acid or mixtures thereof, in an amount sufficient to provide a homogenous aqueous liquid phase and no or low foaming during shaking, said coupler and said solvent present in a weight ratio of 1:2 to 1:6;

d) an acid:amine molar equivalent ratio of 0.7:1 to about 1.3:1; and

e) wherein said composition is substantially free of alkaline earth sulfonates.

2. A composition according to claim 1 wherein the solvent comprises a dibasic ester, essential oil, dialkyl carbonate or mixture thereof.

3. A composition according to claim 1 wherein the solvent comprises ethylene glycol monobutyl ether, diethylene glycol monobutyl ether, ethylene glycol phenyl ether, propylene glycol phenyl ether, or mixture thereof.

4. A composition according to claim 1 wherein the solvent comprises benzyl alcohol.

5. A composition according to claim 1 wherein the amine comprises monoethanolamine.

6. A composition according to claim 1 further comprising surfactant.

7. A composition according to claim 1 having a pH of about 4 to about 10.

8. A composition according to claim 1 having a pH of about 5 to about 9.

9. A composition according to claim 1 in the form of a single phase mixture.

10. A composition according to claim 1 that is not corrosive to skin.

11. A composition according to claim 1 comprising about 5 to about 85 wt. % solvent, about 1 to about 93 wt. % water, about 1 to about 25 wt. % acid coupler and about 1 to about 25 wt. % organic amine.

12. A method for stripping or deep scrubbing a floor finish comprising:

a) applying to the floor finish a composition consisting essentially of sparingly water-soluble floor finish solvent; water; nonethoxylated coupler consisting of toluene, xylene, cumene sulfonic acid or mixtures thereof, in an amount sufficient to provide a homogenous aqueous liquid phase and no or low foaming during shaking said coupler and said solvent present in a weight ratio of 1:2 to 1:6; and an acid:amine molar equivalent ratio of about 0.7:1 to about 1.3:1;

b) allowing the applied composition to soften, dissolve or clean the floor finish; and

c) removing the composition.

13. A method according to claim 12 wherein the solvent comprises a dibasic ester, essential oil, dialkyl carbonate or mixture thereof.

14. A method according to claim 12 wherein the solvent comprises ethylene glycol monobutyl ether, diethylene glycol monobutyl ether, ethylene glycol phenyl ether, propylene glycol phenyl ether, or mixture thereof.

15. A method according to claim 12 wherein the solvent comprises benzyl alcohol.

16. A method according to claim 12 wherein the amine comprises monoethanolamine.

17. A method according to claim 12 further comprising surfactant.

18. A method according to claim 12 having a pH of about 4 to about 10.

19. A method according to claim 12 having a pH of about 5 to about 9.

20. A method according to claim 12 in the form of a single phase mixture.

21. A method according to claim 12 that is not corrosive to skin.

22. A method according to claim 12 comprising 0.05 to about 25 wt. % solvent, about 25 to about 99 wt. % water, about 0.1 to about 10 wt. % acid coupler and about 0.1 to about 10 wt. % organic amine.
