GRADUALLY WATER-SOLUBLE SOLID COMPOSITION AND DEODORIZING AGENT FOR TOILET UTILIZING THE SAME

PROBLEM TO BE SOLVED: To provide a gradually water-soluble solid composition not containing a surfactant, having safety and scarcely causing environmental contamination, a solid composition capable of stably and gradually dissolving an active ingredient of the composition and additives as necessary contained therein and a readily usable and safe deodorizing agent for toilet capable of stably retaining the effect for a long period without polluting the environment. SOLUTION: This solid composition comprises the active ingredient contained in accordance with the intended use and a necessary additive and can gradually dissolve the active ingredients and the additive in water. In the solid composition, isopropyltrioxane and para-oxybenzoic acid ester as dissolution regulators are formulated in a polyethylene glycol which is solid at ordinary temperature. This deodorizing agent for toilet which is gradually soluble in water is obtained by formulating the solid composition with a microorganism and fumaric acid as active ingredients.
