MICROBICIDAL COMPOSITION COMPRISING PHENOXYETHANOL Russian patent published in 2018 - IPC A01N31/14 A01N43/80 A61P31/04 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, specifically to microbiology, and can be used to suppress the growth of microorganisms in an aquatic environment. To this end, a synergistic microbiocidal composition containing two components is used. First component is a nonionic surfactant with the structure: R¹O(CH₂CH(CH₃)O)₅(CH₂CH₂O)₉H, in which R¹ denotes a Cs-alkyl group. Second component is phenoxyethanol. Ratio of the weight of the nonionic surfactant to the weight of phenoxyethanol ranges from 1:1 to 1:18.2766. Synergistic composition is also used, the first component of which is a nonionic surfactant having the structure: R²O(CH₂CH(CH₃)O)₃(CH₂CH₂O)_nH, in which R² denotes a mixture of linear C₈-C₁₄-alkyl groups and n is 5 or 7. Second component is phenoxyethanol. In this case, the ratio of the weight of the nonionic surfactant to the weight of phenoxyethanol ranges from 1:0.1999 to 1:36.5897.

EFFECT: group of inventions allows to effectively inhibit the growth of microorganisms.
