Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to bath preparations, and its purpose is to prevent allergic dermatitis caused by dyes and fragrances contained in bath preparations. To provide a bath agent containing licorice and rice bran as essential ingredients.

(Prior Art and Its Disadvantages) Conventionally, bath additives have been formulated to contain Geraniol and the like as fragrances, and uranikonk and the like as dyes.

Many of the fragrances and dyes added to these bath additives act as allergens, and can easily cause allergic dermatitis on the skin of bathers who bathe in bathtubs containing bath additives. It has the disadvantage that people with eczema, skin inflammation, etc. cannot use it.

(Progress of the invention) The inventors conducted extensive research to eliminate all of the above-mentioned drawbacks, and discovered that by combining licorice and rice bran, the allergenic mechanisms of dyes and fragrances could be suppressed to an amazing extent. Ta. As a result, we found that preparing bath additives containing licorice and rice bran as essential ingredients can be highly effective in preventing allergic dermatitis caused by dyes and fragrances in bath additives, as well as suppressing the aggravation of allergic dermatitis.
This led to this invention.

(Solution Means) That is, the present invention relates to a bath agent containing licorice and rice bran as essential ingredients.

(Structure of the Invention) The scientific name of the licorice used in this invention is GLYCY.

Tohoku licorice) Glycyrrhiza uralensi
s Fjsch.

Dried roots and stolons of et DC, are preferably used.

The reason for using licorice in this invention is that glycyrrhizin contained in licorice has an anti-allergic effect.

In this invention, when the licorice is incorporated into a bath preparation, it is in the form of licorice powder or hot water extract.

To obtain licorice powder, licorice is naturally dried and then ground using a ball mill or the like.

To obtain a hot water extract of licorice, cut licorice and soak the cut pieces in hot water at 40 to 80°C, preferably 60°C, to obtain an extract containing glycyrrhizin as the main component from the cut pieces of licorice. is eluted in hot water and then filtered to obtain a filtrate.

After concentrating the filtrate, it is dried under reduced pressure to obtain a hot water extract powder.

In this invention, in order to incorporate the rice bran into a bath agent, the rice bran is fermented, that is, the rice bran is heated at 20 to 60°C.
1. Leave to ferment the rice bran preferably at 40° C. for 0.5 to 2 hours, preferably 1 hour.

The fermented rice bran is crushed to make fermented rice bran powder.

The reason why rice bran is used in this invention is that its antiallergic effect is dramatically improved when combined with 1↑grass.

In this invention, to obtain a bathing agent from rice bran and licorice, 40 g of sodium lauryl sulfate, 20 g of betaine lauryl dimethylaminoacetate, 40 g of purified water, 1) g of incense, and an appropriate amount of dye are mixed with 4↑ grass powder. If so, 3 to 7 g, preferably 5 g is blended, and if it is a hot water extract of licorice, 1 to 5 g, preferably 3 g is blended, and further 3 to 7 g, preferably 5 g of fermented rice bran is blended.

In this invention, a biological agent may be added as necessary.

The biological name used in this invention is ZTNGIBE.
RIS RIIIZOMA, and in this invention, it refers to ginger of the Zingiberaceae family (Zingiberaceae).
It is preferable to use the rhizome of E. oe as it is, or after removing the cork skin or steaming it and drying it.

In the present invention, in order to incorporate the fish tank into the bath preparation, the fish tank is dried and then powdered to be used as the fish tank powder.

In this invention, when the biochemical powder is added to the formulation of the bath preparation, it is added in an amount of 1 to 3 g, preferably 2 g.

(Effects of the Invention) As described above, bath preparations containing licorice and rice bran as essential ingredients have a surprising effect on preventing allergic dermatitis in bathers caused by fragrances and dyes contained in bath preparations.

By describing the Examples and Experimental Examples of the bath preparation according to the present invention, the effects of the present invention will be made clearer.

(Example 1) After drying the licorice by natural drying, it is crushed.

Rice bran is left at 40°C for 1 hour to ferment the rice bran, and the fermented rice bran is crushed to obtain fermented rice bran.

The above 1↑ grass powder and fermented rice bran powder were blended as follows to obtain a bath agent.

Sodium lauryl sulfate 40.0g Betaine lauryldimethylaminoacetate 20.0g Purified water 39. OgGer
aniol 1. Og
Uranine conch (dye) Licorice powder
5g fermented rice bran powder
5g (Example 2) Cut licorice, immerse the cut pieces in hot water at 60°C, and dissolve the hot water extract from the cut licorice into the hot water,
It is then filtered to obtain a filtrate.

After concentrating the filtrate, it is dried under reduced pressure to obtain a hot water extract powder.

Fermented rice bran powder is obtained by the same treatment as in the first example.

The above hot water extract powder and fermented rice bran powder were blended as follows to obtain a bath agent.

Sodium lauryl sulfate 40.0g Lauryldimethylaminoacetic acid betaine 20.0g Purified water 39.0gGer
aniol (fragrance) 1.0g
Uranin conch (dye) appropriate amount 1↑ Grass hot water extract 3.0g Fermented rice bran powder
5.0g (Example 3) After drying the living matter, powder it and add 2g of this living matter powder to the first
It is added to the bath additives obtained in the examples.

(Comparative example 1) Example 1 except for the licorice powder was used.

(Comparative example 2) Example 1 except for fermented rice bran powder was used.

(Comparative example 3) Example 2 except for the fermented rice bran powder was used.

However, when both licorice and rice bran are combined, their synergistic action results in an amazing effect on preventing skin inflammation. Greater effectiveness in preventing skin inflammation.

Therefore, it can be seen that bath preparations containing licorice and rice bran as essential ingredients have an amazing effect on preventing allergic dermatitis.
