METHOD OF INHIBITING TRANSFER OF INFLUENZA VIRUS Russian patent published in 2011 - IPC A01P1/00 A61L2/18 A61K31/45 A61K31/194 A61K31/191 A01N37/04 

FIELD: chemistry.

SUBSTANCE: invention relates to antimicrobial compositions. The method involves contact between a surface and a composition for 30 minutes in order to achieve the logarithm of decrease of the influenza virus of at least 1.5. Said composition contains: (a) 25-75 wt % of one or more C_1-6 disinfecting alcohols; (b) a virucidally effective amount of organic acid. Said organic acid contains: (i) two or more polycarboxylic aids containing 2-4 carboxylic acid groups. Each of the polycarboxylic acids optionally contains one or more hydroxyl groups, amino groups or both; (ii) a polymeric acid having multiple carboxylic, phosphate, sulphonate and/or sulphate groups; and (c) water. The composition has pH of approximately 5 or lower at 25°C. The composition forms an essentially continuous barrier layer containing an organic acid on the surface.

EFFECT: invention ensures fast and prolonged activity against the influenza virus.
