SURFACE DISINFECTION METHOD AND COMPOSITION SUITABLE FOR USE IN DISINFECTING SURFACE Russian patent published in 2020 - IPC A61L2/16 A61L101/22 A61L101/32 

FIELD: medicine.

SUBSTANCE: group of inventions relates to disinfectology and sanitation and is intended for surface disinfection. Method of surface disinfection, which is contaminated or suspected to be contaminated with microorganisms, where the microorganism is one or more than one of Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Enterococcus hirae, involves a step of bringing the surface into contact with a disinfectant composition containing one or more N-acylated amino acids or N-acylated peptides, or salts thereof; hydrogen peroxide; one or more non-ethoxylated anionic surfactants; ethoxylated anionic surfactant and one or more carboxylic acids. Components are used in the declared codes. Disinfectant composition has pH in range of 1–4.5. Acyl group of N-acylated amino acids or N-acylated peptides or salts thereof has formula R-CO-, where R-CO- is an acyl group, where R is a saturated or unsaturated straight-chain radical C6-C20, and when an N-acylated peptide is used, the peptide has an average molecular weight of about 100 to about 3900 Da.

EFFECT: using the group of inventions enables to increase biocidal activity with respect to a wide range of organisms using low concentrations of organic acids.
