A disinfecting deodorant was prepared in the same manner as in Example 7, except that the trisodium pyrophosphate used in Example 7 was replaced with sodium tripolyphosphate (pKa 25 =9.70), and was put in the same plastic container with a trigger sprayer as used in Example 1 (Example 8). When a 0.5 g portion of the disinfecting deodorant was sprayed, the number of droplets having a particle size of 10 μm or smaller in the mist was 0.87% in a frequency distribution.
