experiment 1
[0037] The somesthetic testing was conducted to determine whether the single use of the aluminum chloride fine powder was able to prevent the itch or not based on the following prescription example. The result is shown in the following. First, since the moisture absorption and the deliquescency are large, pulverization of the aluminum chloride hexahydrate is difficult. Moreover, for direct application to the skin, the aluminum chloride hexahydrate has a high pH and therefore initializes a skin disorder. Accordingly, as the fine powder base, which will be the basic, fine powder formed by combining the aluminum chloride hydrate was used to determine the itch prevention effect by the somesthetic testing. The following fine powder base, which becomes the basic, was employed. Commercially available 160-mesh pass activated zinc oxide of 40 g, talc of 40 g, and 100-mesh pass corn starch of 20 g were used. Powdery aluminum chloride hydrate of 15 g was combined with these materials. The comb...
experiment 2
[0039] The somesthetic testing was conducted to determine whether the single use of the cyclodextrin was able to prevent the itch or not based on the following four prescription examples. The result is shown in the following.
[0040]1. α-CD The result of testing the application of the fine powder alone to the skin over the whole body
[0041]The proportion of itch was 100%. The itch was not removed. Feel of stickiness of the sweat over the whole body was strong, and the itch was not removed.
[0042]2. β-CD The result of testing the application of the fine powder alone to the skin over the whole body
[0043] The proportion of itch was 100%. Feel of stickiness of the sweat over the whole body was strong, and the itch prevention effect was not able to be bodily sensed.
[0044]3. γ-CD The result of testing the application of the fine powder alone to the skin over the whole body
[0045] The proportion of itch was 100%. Feel of stickiness of the sweat over the whole body was strong, and the itch preve...
experiment 3
[0048] Based on of the invention of the present application, the aluminum chloride and β-CD as the main ingredients were combined with the fine powder base, which becomes the basic. The anti-itching powder thus formed was applied to the skin over the whole body to conduct the somesthetic testing. The result is as follows. The test results using the α-CD and the β-CD had no significant difference.
[0049] As the average value of the three examinees, the proportion of itch was in a range of 30 to 0, and the persons felt that the itch was restricted in the 70 percent of the entire test result.
[0050]In 30 percent of the results among them, the proportion of itch was 5% or less.
[0051] To conduct the above-described test, it is considered that the state of the skin is not constant through the year and is affected by temperature / humidity conditions of the external air to some extent. However, even considering errors, the itch prevention effect has been verified from the experiment result of...
