[0008] Further, the mechanism of suppressing odor will be described. Enzymatic degradation of urea is hydrolysis by urease as shown in (Chemical Formula 1). Conditions for advancing this reaction are temperature (0 to 60 ° C.), pH (6 to 9) and the presence of urease, which is an enzyme that most bacteria in the surrounding environment possess. On the other hand, the conditions for suppressing this reaction are as follows:
Fat silver complexes act as inhibitors.

[0009] The silver thiosulfato complex also functions as an inhibitor for uricase involved in the decomposition reaction of uric acid. Uric acid is decomposed into urea to produce ammonia which eventually causes malodor, and thus the silver thiosulfato complex as an inhibitor of uricase also acts to prevent malodor.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, the main cause of odor caused by nitrogen-based wastes discharged from the human body is caused by decay. For example, the main cause of odor in toilets is decay of urine scattered on toilet floor members. When the malodor was generated, the malodor component was ammonia as shown in FIG. It is based on the fact that this ammonia is generated by a decomposition reaction of urea or uric acid, which is a main component in urine, by enzymes possessed by various bacteria.
