PURPOSE:The title composition that is prepared by enveloping insecticide, deodorant and desiccating agent separately with air-permeable, water-soluble high- polymer film or air-permeable high-polymer film so that they do not directly contact one another and combining them in another porous material, thus showing the three functions effectively. CONSTITUTION:The objective composition is composed of (A) an insecticide preparation of 1-1,500mu particle sizes containing a insect-repelling agent such as naphthalene or p-dichloro-benzene enveloped with an air-permeable, water-soluble high-polymer membrane made of, e.g., polyvinyl alcohol or gelatin, (B) a deodorant preparation of 1-1,500mu particle sizes containing a deodorant such as potassium permanganate or zinc sulfate enveloped with an air-permeable high-polymer membrane made of, e.g., ethylcellulose or styrene-butadiene copolymer and (C) a desiccating agent of 1-1,500mu particle sizes containing desiccating agent such anhydrin or silica gel enveloped with the same high-polymer membrane as in (B). The properties of individual components are not damaged. |
