Abstract

A composition having a short disinfecting contact time is disclosed. The composition contains a biguanide or guanide, a quaternary ammonium compound and a basic compound in a specific weight ratio to one another. Compositions having less than a two minute disinfection time are disclosed.

Claims (42)

1. A disinfectant composition comprising:

(i) an antimicrobial biguanide, monoguanide or a combination thereof;

(ii) a quaternary ammonium compound or a mixture of quaternary ammonium compounds; and

(iii) a basic compound comprising an alkanolamine;

wherein the weight ratio of component (i) to component (ii) is in the range of about 1:1.5 to about 1:10; and

the weight ratio of component (i) to component (iii) is in the range of about 1:3 to about 1:15.

2. The disinfectant composition according to claim 1 , wherein the alkanolamine comprises ethanonlamine.

3. The disinfectant composition according to claim 1 , wherein the antimicrobial biguanide comprise polyhexamethylene biguanide or salts thereof.

4. The disinfectant composition according to claim 1 , wherein the quaternary ammonium compound comprises a dialkyldimethylammonium salt, a benzylalkyldimethylammonium salt or a mixture thereof.

5. The disinfectant composition according to claim 4 , wherein the dialkyldimethylammonium salt comprises a di C8-10 alkyldimethylammonium salt and the benzylalkyldimethylammonium salt comprises a benzyl C12-16 alkyldimethyl ammonium salt.

6. The disinfectant composition according to claim 5 , wherein the di C8-10 alkyldimethylammonium salt is a di C8-10 alkyldimethylammonium chloride and the benzyl C12-16 alkyldimethyl ammonium salt is a benzyl C12-16 alkyldimethyl ammonium chloride.

7. The disinfectant composition according to claim 1 , wherein the antimicrobial biguanide comprise polyhexamethylene biguanide or salts thereof, the quaternary ammonium compound is a mixture of quaternary ammonium compounds comprising a diC8-10 alkyldimethylammonium chloride and a benzyl C12-16 alkyldimethyl ammonium chloride and the basic compound comprises a monoethanolamine.

8. The disinfectant composition according to claim 1 , wherein the weight ratio of component (i) to component (ii) is in the range of 1:3 to 1:5 and the weight ratio of component (i) to component (iii) is in the range of 1:5 to 1:8.

9. The disinfectant composition according to claim 7 , wherein the weight ratio of component (i) to component (ii) is in the range of 1:3 to 1:5 and the weight ratio of component (i) to component (iii) is in the range of 1:5 to 1:8.

10. The disinfectant composition according to claim 1 , wherein the pH of the composition is above 8.

11. The disinfectant composition according to claim 1 , wherein the pH of the composition is in the range of about 10.5 to about 13.

12. A disinfectant composition comprising:

(i) an antimicrobial biguanide, monoguanide or a combination thereof;

(ii) a quaternary ammonium compound or a mixture of quaternary ammonium compounds;

(iii) a basic compound comprising an alkanolamine; and

(iv) water;

wherein

component (i) is present in the composition in an amount from about 400 ppm to about 1200 ppm;

component (ii) is present in the composition in an amount from about 2000 to about 3600 ppm; and

component (iii) is present in the composition in an amount from about 3000 ppm to about 7000 ppm.

13. The composition according to claim 12 , wherein component (i) is present in the composition in an amount from about 600 ppm to about 1000 ppm;

component (ii) is present in the composition in an amount from about 2600 to about 3200 ppm; and

component (iii) is present in the composition in an amount from about 4000 ppm to about 6000 ppm.

14. The disinfectant composition according to claim 12 , wherein the basic compound comprises an alkanolamine.

15. The disinfectant composition according to claim 14 , wherein the alkanolamine comprises ethanonlamine.

16. The disinfectant composition according to claim 12 , wherein the antimicrobial biguanide comprise polyhexamethylene biguanide or salts thereof.

17. The disinfectant composition according to claim 12 , wherein the quaternary ammonium compound comprises a dialkyldimethylammonium salt, a benzylalkyldimethylammonium salt or a mixture thereof.

18. The disinfectant composition according to claim 17 , wherein the dialkyldimethylammonium salt comprises a di C8-10 alkyldimethylammonium salt and the benzylalkyldimethylammonium salt comprises a benzyl C12-16 alkyldimethyl ammonium salt.

19. The disinfectant composition according to claim 18 , wherein the di C8-10 alkyldimethylammonium salt is a di C8-10 alkyldimethylammonium chloride and the benzyl C12-16 alkyldimethyl ammonium salt is a benzyl C12-16 alkyldimethyl ammonium chloride.

20. The disinfectant composition according to claim 12 , wherein the antimicrobial biguanide comprise polyhexamethylene biguanide or salts thereof, the quaternary ammonium compound is a mixture of quaternary ammonium compounds comprising

a di-C8-10 alkyldimethylammonium chloride and a benzyl C12-16 alkyldimethyl ammonium chloride and the basic compound comprises a monoethanolamine.

21. A wipe comprising a substrate which is impregnated with the disinfectant composition of claim 1 .

22. The wipe according to claim 21 , wherein the substrate comprises meltblown, coform, spunbond, airlaid, hydroentangled nonwovens, spunlace, bonded carded webs, and laminates thereof.

23. A method of disinfecting a surface in need of disinfection, said method comprises applying the disinfectant composition of claim 1 onto a surface in need of disinfection, leaving the composition on the surface for a period of time.

24. The method according to claim 23 , wherein the period of time is 3 minutes or less.

25. The method according to claim 24 , where the period of time is 90 seconds of less.

26. A method of disinfecting a surface in need of disinfection, said method comprises wiping a surface with the wipe of claim 21 , releasing a portion of the disinfectant composition onto a surface in need of disinfection, leaving the composition on the surface for a period of time.
