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

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.
