不都合を解消することができるのである。It is desirable to use those dihydrazides having a solubility in water of 1 (g / 100 ml) or less at 30 ° C. for the following reasons. That is, according to the research conducted by the present inventors, activated carbon and N--N are mixed when mixed in a wet manner.
The reason why the combination of compounds having a bond reduces both deodorant performance is that most of the compounds having an N—N bond are dissolved in a dispersion medium or a solvent and adsorbed on activated carbon, closing the pores of activated carbon. At the same time, it is considered that the ability of the adsorbed compound having an N—N bond to deodorize aldehydes is also reduced. For example, adipic acid dihydrazide, which is known as one of the compounds having the highest deodorizing ability for aldehydes, has a solubility in water at 30 ° C. of 12.5 g / 10.
It is as large as 0 ml, and when used in combination with activated carbon, the above-mentioned inconvenience occurs. Therefore, a specific dihydrazide having a small solubility in water, specifically, a solubility in water at 30 ° C. of 1 g /
By using 100 ml or less of dihydrazides, the above inconvenience can be solved.

If the particle size of dihydrazide is too large, the desired deodorizing effect is difficult to be expressed because the specific surface area is reduced.On the other hand, if the particle size is too small, the target deodorizing effect is not expressed by closing the pores of the activated carbon. is there. The above dihydrazide compounds may be used alone or in combination of two or more.

とができる。The deodorant composition used in the present invention is composed of dihydrazides, which are poorly soluble in water, and is difficult to dissolve in an aqueous solvent such as an aqueous emulsion resin and dispersed therein. Since it does not block the pores of the activated carbon, it is possible to efficiently remove malodorous components, particularly aldehydes, and maintain the deodorizing effect for a long period of time.
Further, since the water-based solvent is used, it is possible to produce a deodorized product which is safe and has little harm to the living environment or the production environment, and which is simple and can maintain the deodorizing effect for a long period of time.
