DOWICIDE 1E ANTIMICROBIAL, DuPont’s o-phenylphenol brand, is highly soluble in organic solvents and oils but only slightly soluble in water. It is compatible with anionic emulsifiers but typically incompatible with other surfactants. Effective against a wide range of organisms, including Pseudomonas spp., Mycobacterium spp., molds, and fungi, it is used in metalworking fluids to control spoilage and preserve ceramic glazes, adhesives, and leather articles. Its balanced solubility characteristics enhance its versatility in industrial applications.
