Benefits of technology

The patent text describes an anti-itching powder that can be applied to the skin surface using different methods, such as puffing, pressing, or spraying. The powder contains aluminum chloride and / or other ingredients such as burnt alum or basic aluminum chloride. The use of a polymer like burnt alum or basic aluminum chloride can improve the duration of functionality but may have a negative impact on the skin. The hydrate of alum is also a suitable ingredient. The raw material used as a powder base can be similar to baby powder. The use of zinc oxide powder or talc powder as a single base does not bring any problem in effect and can be used in combination with other ingredients like starches or celluloses. Overall, the technical effect of the patent text is to provide an effective and safe anti-itching powder that can be applied to the skin surface in various ways.

Problems solved by technology

However, the polymer is disadvantageous in short durability of functionality, around one-third of the aluminum chloride.
However, the use of zinc oxide powder, which has an effect to protect roots of hair from an influence of solar light, especially ultraviolet rays, or a similar material, and besides talc powder, starches, a celluloses such as HPC, MC, and CMC, and the mixture of them as a single basic base does not bring any problem in effect and a big harmful effect.

Effect test

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...

Abstract

The present invention is anti-itching powder that blocks transmission to stratum corneum and invasion up to epidermal cells by emulsion as a result of further concentration on skin stratum corneum. The emulsion is produced by mixing sweat continuously secreted during rest and sebum. The emulsion becomes a cell disorder composition. Specifically, the anti-itching powder as a fine powder contains main ingredients of aluminum chloride or alum and cyclodextrin. A fine powder as a base is dispersed into and combined with the fine powder. The application of the fine powder over the skin prevents sudden itch without blocking emission and transpiration of moisture in the sweat from the skin stratum corneum.

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This patent specification is based on Japanese patent application, No. 2014-160819 filed on Jul. 20, 2014 in the Japan Patent Office, the entire contents of which are incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to anti-itching powder to outstandingly prevent skin diseases such as eczema and dermatitis.[0004]2. Description of Related Art[0005]Through skin practices for 19 years, a voice of patients from which I have realized is, regardless of age, a voice questioning “Although eruption gets better with medicine, is there anything that can be done about an itch?” A dogma by dermatologists / plastic surgery doctors is that treatment of curing the eruption and soothing the itch is rules and principles derived from medical treatment for health. The medical treatment is to cure diseases. With the stereotype, the medical treatment has been developed in the form of ...
