Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin damage preventive agent suitable for use as a measure against microbial infections in hospitals or as a measure to prevent food poisoning and spoilage in the food manufacturing / processing industry.

[0002]

2. Description of the Related Art In recent years, ethyl acetate for hand washing and disinfection of fingers has been used as a countermeasure for hospital infection of microbial infections such as MRSA (methicillin-resistant Staphylococcus aureus), or as a food poisoning and decay prevention measure in the food manufacturing and processing industry. Disinfection with alcohol is recommended. However, the disinfection with ethyl alcohol causes severe roughening of hands and, on the contrary, facilitates re-establishment of microorganisms, and at the same time, the bleeding accompanying rough hands accelerates the growth of bacteria on the skin.
Therefore, medical personnel, patients, workers in the food industry, and the like are desired to have a skin disinfecting effect as well as a skin protecting effect. In addition, not only the fingers but also the disinfectant for the adherent skin such as the armpit, the crotch, and the toes, which has the same skin protecting effect, is desired.
Further, for those who have dry skin or are easily roughened, it is required that the medium has a moisturizing effect on the skin and the medium is easily vaporized.

Even under such circumstances, most of the 70% ethyl alcohol aqueous solution is used alone, but as a conventional product, ethyl alcohol 67.9 is used.
%, Glycerin 0.1%, L-ascorbic acid 0.05
%, And purified water 31.95% (W / W) having a composition that enhances the moisturizing effect such as Arocrine E (trade name: Ikari Sanitary Co., Ltd.).

[0004]

However, the above-mentioned conventional products have a problem that it is not possible to prevent damage to the skin due to the use of a microbicide, a detergent, etc. for the skin. In addition, since glycerin is added as a moisturizer, a dry feeling is not obtained even after the alcohol is vaporized, and a slight increase in bacterial adhesion rate due to residual moisturization due to the skin coat of glycerin, which is a hydrophilic moisturizer. have. Further, since glycerin is odorless, it has a problem that it strongly feels the odor of ethyl alcohol, and therefore it is necessary to impart another odor of aroma.

Therefore, the present invention has been made for the purpose of solving the problems of the above conventional products.

[0006]

The agent for preventing skin damage of the present invention is prepared by slicing or powdering a plant, alone or in combination, and using water, an organic solvent, or a mixture of water and an organic solvent. It shall consist of the extract.
Then, the plant body includes plant flowers, seeds, fruits, peels, roots,
It can be a stem, leaf, bark, tree or aquatic, marine plant. Furthermore, the extract may be concentrated. Further, the concentrated or dried solid extract may be dissolved and diluted with a microbicidal medium.

Purified water, diluted salt water, mineral water, etc. are used as the water, and ethyl alcohol, ethyl ether, etc. are used as the organic solvent. In the case of a mixed liquid of water and an organic solvent, for example, a mixed liquid of water and ethyl alcohol, water: ethyl alcohol is 0.1-9.9: 9.9-
It can be a ratio of 0.1. Furthermore, in the case of a mixed liquid of organic solvents, for example, a mixed liquid of ethyl alcohol and ethyl ether, the ratio of ethyl alcohol: ethyl ether can be 1 to 5: 5-1.

As the microbiocidal medium, ethyl alcohol, a mixed liquid of water and ethyl alcohol, or the like is used.

[0009]

The agent for preventing skin damage of the present invention is capable of efficiently extracting hydrophilic components and hydrophobic components at the same time with water or an organic solvent by fragmenting or pulverizing a plant body, thereby reducing lipid components,
Combines the effects of both sugar components at the same time. That is, by coating the skin surface with both components such as the vegetable essential oil which is the hydrophobic component and the vegetable polysaccharide which is the hydrophilic component, the dry moisturizing feeling after evaporation of ethyl alcohol is enhanced and at the same time the hydrophobic The skin surface coating of the sexual component has the effect of preventing reattachment of microorganisms. Furthermore, dissolve the skin damage inhibitor in ethyl alcohol, which is a microbiocidal medium.
It has a strong microbicidal effect by diluting it. Also,
The agent for preventing skin damage of the present invention is highly safe when a plant used for eating and drinking is used, and can exhibit a fragrance peculiar to fruit when a fruit or pericarp is used.

[0010]

EXAMPLES The skin damage preventive agent of the present invention will be described in detail below with reference to Examples. (Example 1) The skin damage preventive agent of the present invention was prepared by the following procedure. ． The tangerine peel is dried in the sun, warm air, or cold air to complete dryness. Drying in the sun required 4 to 5 days or more under fine weather and 4 to 5 hours under strong wind at 50 ° C or lower.

[0011]. Shred or powder dry tangerine peel. ． About 100 mL of 70% ethyl alcohol aqueous solution gives about 0.
Add 5 to 100 grams of the above strips or powdered tangerine peel and leave at room temperature for at least 24 hours (mix occasionally or shake gently) for extraction. ． The supernatant is decanted or filtered (when completely sterilized, filtered with a 0.2 μm filter).

[0012]. The solution of (1) is used as it is, diluted with 10 to 70% of ethyl alcohol, or after extraction, it is dried or concentrated. (Examples 2 to 5) Persimmon pericarp (Example 2), persimmon fruit (Example 3), apple pericarp (Example 4), and apple pericarp (Example 5) are the same as in Example 1. The operation was performed. However, persimmon and apple fruits were sliced and dried. (Example 6) With respect to rice bran, the same operation as in Example 1 was performed. It should be noted that, if the rice bran is obtained by drying brown rice, the drying step is not necessary and can be used as it is (when there is a hygroscopic feeling, it is heated and dried before use). (Example 7) A plurality of types of the strips or powdered plants obtained in Examples 1 to 6 were mixed, and the following operation of Example 1 was performed.

As described above, the skin damage preventive agent of the present invention prepared in Examples 1 to 7, a 70% ethyl alcohol aqueous solution (Comparative Example 1), and a commercial product Arocrine E (Comparative Example 2) were applied several times a day. It was sprayed, infiltrated, or applied to the skin, spread evenly on the skin surface by rubbing, and used for 1 week, and a sensory test was performed for the damage prevention effect, moisturizing effect, and odor of the skin. The results are shown in Table 1.

[Table 1]

[0015]

The skin damage preventive agent of the present invention is constituted as described above, and by fragmenting or pulverizing a plant body, a hydrophilic component and a hydrophobic component are treated with water or an organic solvent. And are extracted at the same time, and have the effects of both lipid components and sugar components at the same time, synergistically protecting the skin with lipid components and the moisturizing effect of sugar components, resulting in a dry feeling on the skin after use. A smooth feeling and a moisturizing feeling that lasts together are maintained. And, by the action unique to the above-mentioned plant components, the damage to the skin due to the use of a skin microbicide, a detergent, etc. is prevented and the repair action of damaged skin cells is enhanced. Furthermore, the surface of the skin is sterilized by the action of ethyl alcohol, which is a dissolved and diluted microbiocidal medium, and the skin can be prevented from being roughened by ethyl alcohol. In addition, the skin damage preventive agent of the present invention causes a feeling of mental relief due to the unique aromatic odor of fruits after use, and eliminates the conventional unpleasant disinfectant odor.
