OBJECT OF THE INVENTION -
Traditionally the known commercially available disinfectants are alcohol based preparations. The mentioned alcohols and their mixtures as well as many commercially available preparations are able to inactivate enveloped viruses. However, if a comprehensive antiviral effectiveness is required, the alcohols as well as the preparations known to the skilled person have a number of drawbacks. Thus, it is known that ethanol is effective against enveloped and non-enveloped viruses only in high concentrations. In contrast, propane- l-ol and propane-2-ol are only selectively effective; they are ineffective against most non-enveloped viruses, e.g., against the highly resistant picornaviruses, which include polioviruses and hepatitis A virus. The present invention relates to polyhexamethyleneguanidine (PHMG) based disinfectant having broad-range activity, the use of said disinfectant fori the hygienic disinfection of animate and inanimate surfaces as well as for killing viruses, bacteria and fungi. Further, the invention relates to a disinfection method and to a product containing a disinfectant.

Polyhexamethyleneguanidine (PHMG) and other polyguanidines are derivatives of nitrogenous base - guanidine. The elementary
chains of polyguanides molecules have the
groups with delocalized electrons. In cations of
PHMG
guanidine the positive charge is distributed
symmetrically within the area of equivalent structural surroundings stabilizing the structure therefore, the protonation is energetically favourable process.
PHMG is synthesized in the forms of linear and branched polymers. It's real MW can vary in a wide range of magnitudes
depending on the conditions of synthesis. NH - HC1
Low-molecular PHMG can be synthesised H2N-C-NH2 Η2Ν-((¾)6-ΝΗ.2 by thermal polycondensation of GHC HMDA
hexamethylendiamine (HMDA) with
guanidine hydrochloride (GHC) at temperatures varying from 165 to 250°C. High- molecular products can be synthesized by further polycondensation of low-molecular PHMG in aqueous solution at the presence of alkali.
It has been shown, that after about 9 h
the ammonia ceases to evolve from the m*a Ha (CHa)j H2

polycondensation reaction. The polymers
synthesized are water soluble and can be filtered and desiccated to desired constant weight.
PHMG shows very good and vide spectrum of microbiological activity making it excellent tool for disinfection and other antimicrobial needs, the bigger is the molecular weight the better activity can be reached.
