Antimicrobial composition comprising N-hydroxy heterocyclic thiones

摘要

A composition comprising (a) a metal salt or complex with an organic compound of the general formulahere W may be -SH or an optionally substituted hydrocarbyl group, Q is -OH, hydrogen or optionally substituted hydrocarbyl and Z is hydrogen or optionally substituted hydrocarbyl and Q and Z or Z and W may complete a ring. The compounds are typically metal complexes of thiohydroxamic acids or dithiocarbamates. The metal is typically zinc. The compositions exhibit improved aqueous solubility compared with the metal complexes alone, and can be used as industrial biocides, especially fungicides and particularly in paint films and latices.
