DISINFECTANT COMPOSITION CONTAINING A QUATERNARY AMMONIUM AND A POLYMER OF HEXAMETHYLENE BEGUANIDE HYDROCHLORIDE

摘要

The present invention relates to dininfectant compositions. A bactericidal and fungicidal composition contains the polymer of hexamethylenehexamethylene biguanide (PHNB) and a quaternary ammonium compound. This composition brings an inoculum after one minute contact time to 0.0001% of the initial bacterial population, that is if the population count is 107 germs per ml, only 10 germs will survive. A film forming polymer can also be added, such as for example polyvinylpyrrolidone, in order to obtain a film showing long-lasting germicidal properties. The invention finds an application in the disinfection of medical staff's hands and of linen and clothing soiled with proteins, blood, pus, etc.
