FIELD: medicine, pharmaceutics.
SUBSTANCE: invention refers to medicine, particularly antimicrobial compositions. The antimicrobial composition containing (a) at least one isothiazoline-3 selected from a group consisting of 1,2-benzisothiazolin-3-one, N-(n-butyl)-1,2-benzisothiazolin-3-one and their combinations and (b) at least one zinc compound selected from a group consisting of zinc chloride, zinc sulphide, zinc carbonate, basic zinc carbonate, zinc oxides, zinc hydroxides and their combination where specified isothiazolin-3-one is found in the amount 1 to 500 portions/million, zinc compound is found in the amount 5 to 200000 portions/million, and the mass ratio of isothiazolin-3-one to zinc compound makes 1:2000 to 100:1. Also, the antimicrobial composition contains co-biocide selected from the group including pyrithione salts, pyrithione acids and their combination where specified co-biocide is found in the specified composition in the amount within nearby 0.001 to nearby 1 wt % in relation to total weight of the specified composition.
EFFECT: invention allows ensuring required antimicrobial action with lower consumption rate than that applied for isothiazolinone with no zinc compound.
