(Example 12)
Two chlorine dioxide gas generator packs were prepared in the same manner as in Example 9, one of which was inserted into a 70 mm wide x 110 mm long paper bag, and the paper bag was placed in a 63 year old female sweater pocket (7 o'clock). -19 o'clock) or pajamas pockets (from 0 o'clock to 7 o'clock and from 19 o'clock to 24 o'clock), and the concentration of chlorine dioxide gas generated therefrom was measured. The results are summarized in Table 12. In this example, the paper bag was used to reduce the absorption of moisture such as sweat and the uncomfortable feeling of the chlorine dioxide gas generator pack itself. Here, the ambient temperature was measured with a thermometer, and the chlorine dioxide concentration was measured by bringing a gas detection sensor into contact with the pocket surface. During the trial, the woman complained of discomfort from the generated chlorine dioxide gas.

  The other one is inserted into a paper bag 70 mm wide x 110 mm long, and the paper bag is inserted into a 70-year-old male Y-shirt pocket (7 o'clock to 19 o'clock) or pajamas pocket (0 o'clock to 7 o'clock and 19 o'clock). ˜24 o'clock) and the concentration of chlorine dioxide gas generated therefrom was measured in the same manner as described above.
