Abstract
The invention provides a biocidal concentrate including zinc pyridinethione; and a second biocide selected to be biocidally effective in a pH range complimentary to zinc pyridinethione. The second biocide may be an aromatic halogenated phenol such as triclosan, dichlorophen and trichlorcarban. The invention also provides biocidal cleaning devices and plastic materials and methods of manufacture thereof.
Claims50
