<Example 1>
The sample bottle into which Nonenal was injected was kept in a dryer at 80 ° C. for 30 minutes, and then gas was collected and measured by a gas chromatograph. The following samples were used.

A1: Nonenal alone A2: 10 mg fullerene in Nonenal injection sample bottle (C60 mixed with 10 wt% C70 and C80)
A3: 10 mg of activated carbon was added into the nonenal injection sample bottle. In each case, the gas chromatograph gave the results shown in FIG. From FIG. 1, it can be seen that fullerene has a deodorizing effect of nonenal gas far exceeding activated carbon.
<Example 2>
The sample bottle into which Nonenal was injected was kept in a dryer at 80 ° C. for 30 minutes, and then the gas was collected to prepare the next sample at 37 ° C., which is close to human body temperature.

A1: Nonenal alone A2: 10 mg fullerene in Nonenal injection sample bottle (C60 mixed with 10 wt% C70 and C80)
A3: 10 mg of activated carbon was added into the nonenal injection sample bottle.
After leaving the above three types of samples at 37 ° C. close to the human skin environment at 80% humidity for 2 hours, the gas portion is 10 ⁻⁴ , 10 ⁻⁵ , 10 ⁻⁶ times that of the original substance at 37 ° C. under the same conditions. Dilute with% humidity air and donate to sensory test.

As a result of 30 panelists in the sensory test and evaluated according to the following criteria, it was found that fullerene surpassed activated carbon:
6-level odor intensity display method:
0: Odorless --- 10 ^-6 times that of A2 1: Scent that can finally be sensed (odor threshold concentration) --- ^10-4 , 10 ^-5 times dilution of A2 2: Weak scent that shows what odor it is Threshold concentration) --- ^10-6 dilution of A3 3: Smell that can be easily detected --- ^10-5 dilution of A3 4: Strong odor --- ^10-6 dilution of A1, ^10-4 dilution of A3 Dilution 5: Intense odor --- 10 ^-4 , 10 ^-5 dilution of A1 <Example 3>
In Example 2, PVP (polyvinylpyrrolidone) composite fullerene was used instead of fullerene. As a result, almost the same result as in Example 2 was obtained.
<Example 4>
A woven fabric for underwear of 80% cotton and 20% polyester was prepared, and this was immersed in an ethanol solution in which the same fullerene as in Example 1 was dissolved and dispersed, and then dried to give the fullerene to the woven fabric. Supported.

  The underwear with a high deodorizing effect was produced in the above procedure.
