[Industrial Application Field] The present invention relates to a bath additive that has a skin-lightening effect. [Prior art] Bath additives are used by dissolving them in hot water when taking a bath. Conventionally, their purposes were (1) to soften hard water and make it easier to clean, and (2) to add color and fragrance to the hot water to make it more appealing. (3) It contains active ingredients of hot springs or medicines to provide therapeutic or cosmetic effects, and (4) It is used to cleanse the skin. These bath additives are mainly composed of inorganic salts such as sodium chloride, quicklime, and sodium bicarbonate, which are colored and flavored and can be easily dissolved in hot water. And as a medicinal ingredient, sulfur,
Contains ingredients such as honeysuckle, mineral springs, yunohana, borax, fenugreek, touki, keigai, etc. It also contains oxidizing agents such as sodium perborate and potassium permanganate as sterilizing and bleaching agents. [Object of the Invention] The present invention aims to provide a new bath additive that has a skin whitening effect in addition to the objectives of conventional bath additives such as skin cleansing, feeling refreshed, and skin treatment. This is the purpose. [Structure of the Invention] The present invention provides a bath agent that significantly brightens the skin by incorporating kojic acid into the bath agent base material and using the bath agent by dissolving it in hot water when taking a bath. It is. The bath agent base material used in the present invention is a base material generally used for bath agents. For example, as a water softener,
Inorganic salts such as soda carbonate, sodium sesquicarbonate, and sodium phosphate, skin vitality activating ingredients such as table salt, bactericidal bleaching agents such as potassium permanganate, carbon dioxide bubble generators such as tartaric acid and citric acid, sodium sulfate, and starch. These include hygroscopic agents such as acids, various other medicinal ingredients, pigments, and fragrances. Kojic acid is added to the base material of the above bath agent. Kojic acid is derived from Aspargillus oryzae, Aspargillus flavus, Aspargillus fumari,
5-oxy-2-oxymethyl- produced from various carbohydrate compounds by Aspargillus fungi such as Aspargillus wench, Aspargillus duulans, and Aspargillus candidus.
It is γ-pyrone. This substance has extremely low toxicity; for example, in acute toxicity tests using mice and rats, oral, intraperitoneal, and subcutaneous administration were performed.
LD 50 was approximately 2.5-3.5 g/Kg in all cases. Furthermore, kojic acid is a safe substance that causes no primary or cumulative irritation to the skin, and no allergic reactions are observed. In the bath agent of the present invention, the amount of kojic acid added is
It is added to bath additives at a rate of approximately 1 to 20 g in a bathtub with a capacity of about 200. The bath additives of the present invention are commercialized in the form of powders, granules, and the like. [Example] Sodium chloride 62.0g, borax 3.0g, sodium sesquicarbonate 15.0g and sodium sulfate 5.0g
Stir to mix evenly. Add 10.0 g of kojic acid, 0.6 g of borneol, and 3.0 g of dextrin to one part of the above mixture and mix well. To this, add 0.4 g of turpentine oil and geraniol-denatured alcohol in which perfume and tar pigment are dissolved and mix evenly. The rest of the mixture was added to this mixture, mixed evenly, and passed through a sieve to prepare granules. This is about 30
The mixture was air-dried at ℃ and sealed in 10g portions in polypacks to prepare bath additives. [Effects of the Invention] The fair skin effect when using the bath agent of the present invention is shown below. Test method: In the summer, 20 men exposed their backs for 5 hours to 10
Divided into two groups, A and B, group A added 10g of the bath additive obtained in Example 1 to a 200-volume bathtub each time.
I took a bath for 30 minutes once a month for two months. As a control, Group B was tested under the same conditions as Group A using a bath additive from Example 1 except that kojic acid was removed. Then, the lightness (Y) of the sunburn was measured every week using a color difference meter. The results were as shown in the table below.

【表】 以上の結果より明らかな通り、3〜7週におい
て本発明の浴剤を使用した群が対照の群より有意
に明度が上昇し、本発明の浴剤がヒトの肌の脱色
に効果があることは明らかである。
[Table] As is clear from the above results, the brightness of the group using the bath additive of the present invention significantly increased compared to the control group in weeks 3 to 7, and the bath additive of the present invention was effective in bleaching human skin. It is clear that there is.
