Abstract
Abstract An effective amount of nonionic trialkyl amine and optionally one of a Group II-A or Group II-B metal salt of a monocarboxylic acid having a carbon chain length of 1 to 4, cadmium chloride, or ethylenediaminetetraacetic acid when dispersed in a liquified plastic material may be applied to a surface as a thin film which is fungicidal and bactericidal and effective against both Gram positive and Gram negative organisms including pseudomonas aeruginosa.
