DISINFECTANT FOR SURFACES WITH RESIDUAL BIOCIDE PROPERTIES Russian patent published in 2022 - IPC C08G73/00 C08L101/00 A01N33/12 A61L2/16 A61L2/18 A61L101/46 

FIELD: chemistry.

SUBSTANCE: present invention relates to a disinfectant giving residual biocide properties, as well as to a product including this disinfectant, and to a method for use of a disinfectant. The disinfectant includes a polymer binding component, where this polymer binding component is oxazoline homopolymer, as well as a biocide compound, and a carrier. Oxazoline homopolymer is a compound of the formula: , where R₁ and R₂ are end groups, which are determined by a polymerization method used for synthesis of oxazoline homopolymer, R₃ is an ethyl group, and n is in the range from 10 to 1,000,000. The biocide compound is a quaternary ammonium compound and is selected from a group: chloride of n-alkyl dimethyl benzyl ammonium, chloride of di-n-octyl dimethyl ammonium, chloride of didecyl dimethyl ammonium, saccharinate of n-alkyl dimethyl benzyl ammonium, chloride of n-octyl decyl dimethyl ammonium, and chloride of 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium, or a mixture of quaternary ammonium compounds, including chloride of n-alkyl dimethyl benzyl ammonium, chloride of n-octyl decyl dimethyl ammonium, chloride of di-n-decyl dimethyl ammonium, and chloride of di-n-octyl dimethyl ammonium.

EFFECT: obtained disinfectant is effective for a wide range of productions and applications, as well as gives residual biocide properties to the treated surface, which persist for a long time, so that the surface can continue to reduce a number of microorganisms for a long period of time after the application of the disinfectant.
