SURFACE ACTION DISINFECTANT WITH RESIDUAL BIOCIDAL PROPERTY Russian patent published in 2022 - IPC A01N37/20 A01N25/10 A01N31/02 

FIELD: chemistry.

SUBSTANCE: invention relates to disinfectants; it can be used in medicine, food industry, agriculture and in everyday life. A disinfecting composition contains: a polymer binder, where the polymer binder is polyethyloxazoline, and a component selected from a biocidal compound, where the biocidal compound is a quaternary ammonium compound or a mixture of quaternary ammonium compounds. In this case, the quaternary ammonium compound has the structure:

,

and it can be selected, in particular, from n-alkyldimethylbenzyl ammonium chloride, di-n-octyl dimethyl ammonium chloride, dodecyl dimethyl ammonium chloride, n-alkyl dimethyl benzyl ammonium saccharinate, 3-(trimethoxysilyl) propyldimethyloctadecyl ammonium chloride. The quaternary ammonium compound is a polymer variant with the following structure:

or

,

and it can be selected, in particular, from polyamine obtained from dimethylamine and epichlorohydrin, polydiallyldimethyl ammonium chloride, polyDADMAC, or a compound containing a biguanide fragment in a molecule. In this case, the disinfecting composition is substance for the insulation of biofilm created by pathogen microorganisms.

EFFECT: disinfecting composition is used for the treatment of surface in order to form film with the capability of fast destruction of bacteria and other microorganisms during at least 24 hours after the application of film to the treated surface.
