Synergistic microbiocidal composition containing a mixture of a bicyclic polyoxymethyleneoxazolidine and an acroloin/formaldehyde polycondensation product

摘要

A synergistic microbiocide comprising a member selected from the group consisting of (1) an N-alkyl (C8-C30) dimethylbenzylammonium halide and (2) a polycondensation product of acrolein/formaldehyde in a molar ratio of 1:10-10:1 in combination with (3) a bicyclic polyoxymethyleneoxaazolidine having the formula: <IMAGE> in which each R represents hydrogen, an alkyl of 1-6 carbons, phenyl, halophenyl or -(CH2O)mCH2OH in which m is 0-2 and n is 0-4, the ratio of (1) or (2) to (3) being 1:10-10:1 by weight.
