<p>- i Patent Application of SIDNEY MELAMED for ENCAPSULATED SOLID MICROBIOCIDAL ARTICLE D.N. 82-49 By: LEJ/ets There is disclosed as an article a solid particulate microbiocidal composition embedded in a water-insoluble, high-melting solid binder useful in aqueous systems. The microbiocidal composition is produced from a microbiocidal compound having sufficient water solubility to provide a microbiocidally effective amount thereof in admixture with an inert, finely-divided water-insoluble solid carrier material. Especially useful are microbiocidal 3isothiazolones and 2-substituted-1,2-benzisothiazolones, and metal salt stabilized derivatives thereof, admixed with silicaceous diatomaceous earth. These articles afford controlled release of active ingredient and also afford a safer form of the active ingredient heretofore known to be relatively irritating to the skin of man at high concentrations in aqueous solution.</p> |
