  • Patent number: 10272104
    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 water in the sweat from the skin stratum corneum.

  • Patent number: 10064975
    Abstract: The present invention relates to a biological film-forming agent which is for facilitating wound healing and coating and protecting biological organs, and for coating and protecting damaged cells, wound surfaces, organs and damaged sites of organs, and wound surfaces reaching soft tissues such as muscle and facia, periosteum or bone cortex. Provided is a biological film-forming agent for suppressing exudation of intracellular fluid from damaged cells, suppressing expansion of inflammation reactions and secondary inflammation reactions resulting from production of fibrin and eliminating adverse effects caused by formation of stabilised fibrin on healing. Various problems can be solved by using the agent containing aluminium chloride, cyclodextrin and water as base components.

  • Publication number: 20170035801
    Abstract: The present invention relates to an anti-itching agent that prevents itch of skin. An emulsion, which is produced when sebum and sweat continuously secreted are mixed, contains a stimulatory composition having aqueous and oily properties and can be a causative agent of itch. In addition, the emulsion can be a cell disorder composition. Furthermore, the emulsion causes itching and becomes a causative agent triggering and promoting dermatitis. The problem can be solved by blocking the emulsion by a skin-degenerative stratum corneum, which is formed by an action of an aluminum chloride and water, the aluminum chloride and a cyclodextrin.

  • Publication number: 20170035802
    Abstract: The present invention relates to an anti-itching agent that prevents itch of skin and a method for treating itching. An emulsion, which is produced when sebum and sweat continuously secreted are mixed, contains a stimulatory composition having aqueous and oily properties and can be a causative agent of itch. In addition, the emulsion can be a cell disorder composition. Furthermore, the emulsion causes itching and becomes a causative agent triggering and promoting dermatitis. The problem can be solved by blocking the emulsion by a skin-degenerative stratum corneum, which is formed by an action of an aluminum chloride and water, the aluminum chloride and a cyclodextrin. A polyphenol compound or a tannic acid can be also contained.
