Abstract

PURPOSE:To provide a powdery bathing agent containing an oxyacid sodium salt compound as a main component and compounded with a coloring component of SHIKON (root of Lithospermum erythrorhizon) and optionally a pH-modifier, changing the color in the bath and having medicinal effect. CONSTITUTION:A part of a powdery bathing agent composed mainly of a neutralized or alkalinized oxyacid sodium salt compound or an acidified oxyacid sodium salt compound as a base is colored with SHIKON powder, SHIKON extract or shikonin to a color corresponding to the pH attained by the alkalinizing or acidifying treatment. The obtained colored component is used as a component of the objective powdery bathing agent. The agent is compounded with a colorless oxyacid sodium salt compound and optionally a pH-modifier (e.g. citric acid) at a specific ratio to exhibit an acidic nature in an aqueous solution when the powder is mixed with a neutralized or alkalinized oxyacid sodium salt compound or exhibit an alkaline nature and develop a reverse color when the agent is compounded with an acidified oxyacid sodium salt compound.

Description

[Detailed Description of the Invention] [Field of Application in Industry-1-] The present invention relates to (1) bundled bath additives, and more specifically to powdered bath additives that change color when placed in a bath and have medicinal effects. It is something.

[Conventional technology]

The active ingredient of Shikon, which is the dried root of Mura 4-no-ki, is PH.
It has been known for a long time that color development changes depending on the color.

In addition, a skin cosmetic rice bran containing purple root extract is described in Japanese Patent Application Laid-Open No. 52-27692, and purple root is effective as an external treatment for skin diseases, cuts, burns, eczema, etc. It is also known that

However, shikonin is effective against hemorrhoids and has not been used in bath additives.

[Problem that the invention attempts to solve]

In view of the above circumstances, the present inventors focused on the fact that purple root is effective as a treatment for hemorrhoids, and in order to develop new uses by combining this with the effect of changing color depending on PH, The object of the present invention is to provide a powdered bath additive containing the same.

Shikonin is a naphthoquinone compound expressed by the formula below, which is made from purple roots, etc., and is contained in a few percent in natural purple roots, purple callus obtained by tissue culture, and purple root extract extracted from it. These purple roots contain a small amount of shikonin and a large amount of various ester compounds of shikonin.

[Means for solving problems]

A part of the powdered bath agent whose main component is a sodium oxychloride compound is treated with the active ingredient Shikon in an alkaline or acidic manner (PL) (a component that is colored and mixed in a predetermined color depending on the property, and in an aqueous solution. By blending the remaining colorless sodium oxychloride compound and, if necessary, a PH regulator in a predetermined ratio, the color was changed to the opposite acidity or alkalinity.

Zunawachi purple root powder, purple root extract, or shikonin (preferably shikonin) is generally known to rapidly turn blue in an alkaline environment with PI (about 81!t-) when placed in an aqueous solution, depending on the concentration. However, in a neutral to weakly alkaline environment where P T-( is about 7 to 8
In a moderately acidic environment F, it exhibits a pale red color.

Therefore, for example, sodium hydrogen carbonate-based 1~
A component obtained by treating a lithium oxychloride compound with alcoholic potassium hydroxide and adding an alcoholic solution of shikonin becomes a blue colored component. If this powdered bath agent is mixed with an uncolored sodium oxy-acid compound, etc., mainly consisting of sodium sulfate, and citric acid as a pH regulator in a predetermined ratio, when this powdered bath agent is placed in an aqueous solution, it will become acidic. In turn, the color can change to, for example, pale red.

Further, for example, a component obtained by adding an alcoholic solution of shikonin and citric acid to a sodium oxysate compound mainly composed of sodium sulfate becomes a pale red colored component. If this is mixed in a predetermined ratio with an uncolored sodium oxysate compound mainly composed of sodium bicarbonate, which is alkaline in an aqueous solution, this powdered bath agent can be mixed with water. 9 When placed in liquid,
It can turn alkaline and change color to pale blue.

In this way, the powdered bath additive of the present application, in the state of an aqueous solution,
Taking advantage of the fact that the PI (PI) is different and therefore the color development is different, it is blended in a predetermined ratio to give it an interesting bathing agent and to give it beautiful coloring.

[For production]

The antibacterial and granulation-forming effects of shikonin are generally known. However, the inventors have focused on the fact that shikonin has a therapeutic effect on hemorrhoids, and intend to provide a new bath additive.

The bath salts used in the present invention are bath powders that are thrown into a whirlpool during bathing to soften the water and at the same time impart a fresh, pleasant smell to the water. As the main raw material, sodium oxy-acid salt compounds, which are anhydrous salts and hydrated salts such as sodium carbonate, trisodium phosphate, sodium chloride, and boric acid, are generally used.

In the present invention, as described above, purple root powder, purple root extract, or shikonin are used as coloring agents, but purple root powder and purple root extract contain relatively large amounts of impurities.
In the present invention, it is preferable to use shikonin, especially shikonin with a purity of 80% or more, rather than purple root powder or purple root extract, since it is sensitive to sunlight and heat, easily causes discoloration and fading, and also has an unpleasant odor. .

The product can be obtained by hydrolyzing M in an alkaline aqueous solution 7 and then adding sulfuric acid etc. 1-7 to perform acid precipitation. If the purity is less than 80%, it will tend to have a dark color and may have a stomach odor.

In particular, in the present invention, shikonin with a purity of 90 to 100% is preferred. , 2, and 2 are extremely stable.

Hot water made from these powdered bath salts also softens the water and gives off a fresh smell, and bathing in it was particularly effective in treating hemorrhoids that involve piles.

〔Effect of the invention〕

As described above, the powdered bath additive of the present invention has two characteristics: the color development in the powder state and the color development in the aqueous solution state in which water is dissolved during use. Please be careful when using! ! ! There is something deep. In addition, various pharmacological effects based on the active ingredient of purple root or shikonin are added, and since shikonin is a crude drug, there are no safety problems.

In particular, when using shikonin with a purity of 80% or more, the color development and its changes in the powder and aqueous solution states are more beautiful, and it is also extremely stable, so it can be expected to have many useful and pharmacological effects. It is a bath additive.
