ABSTRACT:
An improved article of a membrane permeable to water and impermeable to microbiocidal compounds containing therein a solid particulate microbiocidal composition which is useful in aqueous systems, wherein the composition is produced from aqueous solutions of a water-soluble microbiocidal compound absorbed in an inert, finely-divided water-insoluble solid carrier. Especially useful are microbiocidal 3-isothiazolones and 2-substituted-1,2-benzisothiazolones, and metal salt stabilized derivatives thereof, absorbed into a silicaceous diatomaceous earth in a sealed, perforated membrane, for example, a perforated bag, produced from polyethylene. These articles afford a form, which is safer for handling.
