SURFACE-ACTING DISINFECTANT WITH RESIDUAL BIOCIDE PROPERTY Russian patent published in 2022 - IPC A01N37/20 A01N31/02 A01N33/02 A01N25/10 

FIELD: chemistry.

SUBSTANCE: invention relates to disinfectants; it can be used in medicine, food industry, agriculture, and in everyday life. A disinfectant composition contains: a polymer binder in the range from 0.1% to 10% by wt. or from 0.1% to 155 by wt., while the polymer binder is oxazoline homopolymer, a biocide compound in the range from 0.05% to 10% by wt., surfactant in the range from 0.01% to 10% by wt., pH-regulating substance in the range from 0.01% to 10% by wt. or from 0.01% to 30% by wt., glycolic ether in the range from 1% to 10% by wt. or to 30% by wt., and the rest up to 100% by wt. is water. The biocide compound is a quaternary ammonium compound or a mixture of quaternary ammonium compounds, where the quaternary ammonium compound has a structure:

,

and it can be selected, in particular, from n-alkyldimethylbenzyl ammonium chloride, di-n-octyl dimethylammonium chloride, dodecyldimethyl ammonium chloride, n-alkyl dimethylbenzyl ammonium saccharinate, 3-(trimethoxysilyl) propyldimethyloctadecyl ammonium chloride.

EFFECT: disinfectant composition is used for the surface treatment 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.
