PROBLEM TO BE SOLVED: To control the decomposition, deterioration of physical property, and coloring of a binder by making a composition containing composite particles in which a granular semiconductor photocatalyst and granular amorphous calcium phosphate are integrated and a binder. SOLUTION: An antibacterial deodorant composition consists of composite particles in which a granular semiconductor photocatalyst and granular amorphous calcium phosphate are combined/integrated and a binder. Slurry containing amorphous calcium phosphate(ACP) particles of prescribed particle size is added with a semiconductor photocatalyst of particle size smaller than that of the PCP particles and agitated to make a kind of mixed slurry in which the aggregation of respective particles is controlled. By granulating and drying the slurry, composite particles in which particles made by the adhesion of the semiconductor photocatalyst particles to the peripheries of the ACP particles are combined/ integrated are obtained. The binder is not restricted in particular and uses a organic resin such as a synthetic resin, an inorganic substance, and others. |
