Abstract

A non-staining composition which is bactericidal, fungicidal and viricidal when applied, comprising in combination; an iodine free bactericide and/or fungicide having a residual efficacy lasting longer than 3 hours on surfaces against bacteria and fungi and a peroxide. A carrier may also be present. The bactericide and/or fungicide may be for example triclosan or a quaternary ammonium compound, or preferably a PVP-phenolic biocide complex (eg PVP-triclosan) or PVAlc/quaternary ammonium compound complex (eg PVP/benzalkonium chloride). The peroxide may be hydrogen peroxide.

Claims (22)

1. A composition which is bactericidal, fungicidal and viricidal when applied consisting essentially of:

(1) an iodine free Poly Vinyl Alcohol (PVAlc) or its copolymers and a benzalkonium chloride;

(2) a peroxide, wherein the peroxide is present and in an amount not exceeding 7% w/w; and,

(3) a carrier consisting of water, an alcohol and optionally glycols, fragrances and colorants, which creates a film on a disinfected inanimate or animate surface on evaporation;

wherein said film has a residual efficacy lasting longer than 3 hours on surfaces against bacteria and fungi when dry.

2. A composition according to claim 1 wherein the peroxide is hydrogen peroxide.

3. A composition according to claim 1 wherein the composition has a residual efficacy lasting longer than 12 hours on inanimate surfaces against bacteria and fungi.

4. A composition according to claim 1 wherein the ratio of PVAlc:benzalkonium chloride is in a range of from 1:0.05 to 1:1 (w/w) where a dry residue is required.

5. A composition according to claim 1 wherein the ratio of PVAlc:benzalkonium chloride is 1:1 or greater if a dry residue is not required.

6. A composition according to claim 1 wherein the ratio of PVAlc:benzalkonium chloride is 1:2 or greater if a dry residue is not required.

7. A composition according to claim 1 wherein the benzalkonium chloride is present in an amount of 0.2 to 12% (w/w).

8. A composition according to claim 1 wherein the PVAlc is present in an amount of 0.5 to 30% (w/w).

9. A composition according to claim 1 wherein the peroxide is present in an amount less than 15% w/w.

10. A composition according to claim 1 wherein the peroxide is present in an amount of 5 to 7%.

11. A composition according to claim 1 wherein the peroxide is present in an amount of 1.0 to 3%.

12. A composition according to claim 1 wherein the alcohol has a boiling point of 97° C. or below.

13. A composition according to claim 1 wherein the alcohol is selected from the group consisting of ethanol, isopropanol, and propanol.

14. A composition according to claim 1 wherein said composition is free from amines.

15. A composition which is bactericidal, fungicidal and viricidal when applied, consisting essentially of a combination of polyvinyl alcohol-benzalkonium chloride complex, hydrogen peroxide, and a carrier consisting of water, an alcohol and optionally glycols, fragrances and colorants wherein the amount of hydrogen peroxide is in the range of 1.0% to 3% w/w.

16. A composition according to claim 15 wherein the alcohol has a boiling point of 97° C. or below.

17. A composition according to claim 15 wherein the alcohol is selected from the group consisting of ethanol, isopropanol, and propanol.

18. A composition according to claim 15 wherein said composition is free from amines.
