Abstract

The present invention relates to a liquid composition comprising: a) at least one alcohol; b) at least one hydrocarbon or hydrocarbon mixture; c) at least one peroxide agent; d) water. The compositions of the invention possess antimicrobial and enhanced sporicidal properties.

First claim

We claim:

1. A liquid composition comprising:
a) about 40-95 wt-% of at least one alcohol;
b) about 1-10 wt-% of at least one hydrocarbon or hydrocarbon mixture;
c) about 1-10 wt-% of at least one peroxide agent;
d) water,
wherein the liquid composition is an antimicrobial, bleaching or disinfectant composition,
wherein the hydrocarbon or hydrocarbon mixture comprises pentane, hexane, heptane, a petroleum ether, or a combination thereof, is an active ingredient of the composition, not a propellant and has a boiling point in the range of about 40° C. to about 80° C.,
wherein the at least one alcohol is a C 2 -C 6 alcohol, and
wherein the peroxide agent comprises hydrogen peroxide, a peroxycarboxylic acid, a derivative thereof, or a mixture thereof.

2. The composition of claim 1 , wherein the ratio of the at least one alcohol to the at least one hydrocarbon or hydrocarbon mixture is in the range of about 5: 1 to 100 : 0.1.

3. The composition of claim 1 , wherein the hydrocarbon is a hydrocarbon mixture.

4. The composition of claim 1 , wherein the hydrocarbon or hydrocarbon mixture has a boiling point in the range of about 30° C. to about 40° C.

5. The composition of claim 1 , wherein the alcohol comprises ethanol, 1-propanol, 2-propanol, n-butan-1-ol, n-butan-2-ol, tert-butanol, pentan-1-ol, pentan-2-ol, pentan-3-ol, 3-methylbutan-2-ol, 2,2-dimethylpropanol, hexan-1-ol, hexan-2-ol, hexan-3-ol, an isomer thereof, or a combination thereof.

6. The composition of claim 1 , wherein the composition has about 1-5 wt-% of the at least one hydrocarbon.

7. The composition of claim 1 , wherein the composition has about 60-80 wt-% of the at least one alcohol.

8. The composition of claim 1 , wherein the composition has about 3-8 wt-% of the at least one peroxide agent.

9. The composition of claim 1 , wherein the composition
has about 40-95 wt-% of the at least one alcohol;
about 1-10 wt-% of the at least one hydrocarbon; and
about 1-10 wt-% of the at least one peroxide agent wherein the at least one alcohol is a C 2 -C 6 alcohol and the at least one hydrocarbon has a boiling point of about 40-60° C.,
wherein the hydrocarbon comprises pentane, hexane, heptane, a petroleum ether, or a combination thereof.

10. The composition of claim 1 , wherein the composition has a pH of about 1-10.

11. A method for disinfection or cleaning of a hard surface or a soft surface comprising contacting a hard or soft surface with an effective amount of the composition according to claim 1 .

12. The composition of claim 1 , wherein the composition has an antimicrobial or microbiocidal activity.

13. The composition of claim 9 , wherein the composition has an antimicrobial or microbiocidal activity.

14. The composition of claim 1 , wherein the composition is a bleaching composition.

15. The composition of claim 7 , wherein the C 2 -C 6 alcohol comprises propanol.

16. The method of claim 11 , wherein the surface comprises a surface of a medical or dental instrument, a surface of a medical or dental device, a surface of a pharmaceutical equipment, or a surface of a pharmaceutical or cosmetics manufacturing equipment.
