Abstract

A composition is provided for use as a hard surface cleaner, sanitizer and/or disinfectant. In a preferred embodiment, the composition comprises an alkanesulfonic acid; a source of peroxide; an effective amount of a stabilizer; and water.

First claim

The invention claimed is:

1. A composition for use as a hard surface cleaner, disinfectant and/or sanitizer, said composition consisting of:
an alkanesulfonic acid;
a source of peroxide;
an effective amount of a stabilizer selected from the group consisting of:
monoethanolamine; taurine; taurine derivatives, taurolidine; taurocholic acid; tauroselcholic acid; tauromustine; 5-taurinomethyluridine and 5-taurinomethyl-2-thiouridine; homotaurine (tramiprosate); acamprosate; taurates; and aminoalkylsulfonic acids where the alkyl is selected from the group consisting of C1-C5 linear alkyl and C3-C5 branched alkyl; and
water.

2. The composition according to claim 1 , where said alkanesulfonic acid is present in an amount ranging from 0.5 to 5 w/w % of the total weight of the composition.

3. The composition according to claim 1 , where said source of peroxide is present in an amount ranging from 0.5 to 10 w/w % of the total weight of the composition.

4. The composition according to claim 1 , where said stabilizer is present in an amount ranging from 0.05 to 5 w/w % of the total weight of the composition.

5. The composition according to claim 1 , where said alkanesulfonic acid is selected from the group consisting of: alkanesulfonic acids where the alkyl groups range from C1-C6 and are linear or branched; and combinations thereof.

6. The composition according to claim 1 , where said alkanesulfonic acid is selected from the group consisting of: methanesulfonic acid; ethanesulfonic acid; propanesulfonic acid; 2-propanesulfonic acid; isobutylsulfonic acid; t-butylsulfonic acid; butanesulfonic acid; iso-pentylsulfonic acid; t-pentylsulfonic acid; pentanesulfonic acid; t-butylhexanesulfonic acid; and combinations thereof.

7. The composition according to claim 1 where said alkanesulfonic acid is methanesulfonic acid.

8. The composition according to claim 1 where said alkanesulfonic acid has a molecular weight below 300 g/mol, preferably said alkanesulfonic acid has a molecular weight below 150 g/mol.

9. The composition according to claim 1 , where said source of peroxide is selected from the group consisting of: hydrogen peroxide; benzoyl peroxide; percarbonates; perborates; persulfates; and combinations thereof.

10. The composition according to claim 1 wherein said source of peroxide is hydrogen peroxide.

11. The composition according to claim 1 , where the stabilizer is an alkanolamine.

12. The composition according to claim 1 , where the composition has a pH of less than 3.

13. The composition according to claim 1 , where the composition has a pH of less than 2.

14. The composition according to claim 1 , where the composition has a pH of less than 1.

15. Method of disinfecting a hard surface, wherein said method comprises the steps of:
providing a composition according to claim 1 ;
providing a surface which requires disinfecting; and
applying the composition onto said surface for a duration of time sufficiently long enough to destroy micro-organisms present on said surface.

16. Method of sanitizing a hard surface, wherein said method comprises the steps of:
providing a composition according to claim 1 ;
providing a surface which requires sanitizing; and
applying the composition onto said surface for a duration of time sufficiently long enough to destroy micro-organisms present on said surface.

17. A composition for use as a hard surface cleaner, disinfectant and/or sanitizer, said composition consisting of:
an alkanesulfonic acid selected from the group consisting of: methanesulfonic acid; ethanesulfonic acid; propanesulfonic acid; 2-propanesulfonic acid; isobutylsulfonic acid; t-butylsulfonic acid; butanesulfonic acid; iso-pentylsulfonic acid; t-pentylsulfonic acid; pentanesulfonic acid; t-butylhexanesulfonic acid; and combinations thereof;
a source of peroxide;
an effective amount of a stabilizer; and
water.
