摘要

A biocidal concentrate including a metal pyridinethione; and a second biocide selected to be biocidally effective in a pH range complementary to zinc pyridinethione, both first and second biocides being present in synergistically effective amounts. The second biocide may be selected from the group consisting of halogenated phenols, phenols, derivatives of halogenated phenols, derivatives of phenols, and trichlorocarbon. Also provided are biocidal cleaning devices and plastic materials containing the biocidal concentrate and methods of manufacture thereof.
