Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath agent. More specifically, most of the foaming components are foamed and dissolved on the surface of the bath water so that they have excellent solubility and do not adversely affect the bath material. A mold bath agent.

[0002]

2. Description of the Related Art Conventionally, a bath agent containing an inorganic salt as a main component has been marketed, but recently, the amount used is increasing because of pursuing the effect of promoting blood circulation. However, increasing the amount used causes a decrease in solubility and causes inconvenience such as feeling roughness on the buttocks and the like.

Further, a bath agent for generating a gas such as carbon dioxide is
The foaming and plosive sounds inspire purchasers (consumers) to purchase. However, bath agents that generate carbon dioxide gas in the form of tablets have a long dissolution time, and because reaction foaming occurs at the same location at the bottom of the bath, there is a local adverse effect on the bath material (FRP).
There is concern about deterioration of the resin).

Further, a bath agent in which high-pressure gas is enclosed in sugar is also known, but this has poor solubility and has a risk of damaging the skin. Recently, a card-type foaming bath agent has also been reported (Japanese Patent Publication No. 4-27207), but since this product attaches great importance to the hardness of the molded product, it does not have excellent solubility and can be used. Was not.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a bath preparation which is excellent in solubility, has no roughness, and does not adversely affect the bath material.

[0006]

Means for Solving the Problems As a result of intensive studies to solve the above-mentioned problems, the inventors of the present invention molded a foaming bath agent into granular to flat pieces having certain conditions, The inventors have found that a bath agent can be obtained which foams on the surface of a bath water, has excellent solubility, does not have roughness after foaming, and does not adversely affect the bath material, and has completed the present invention.

That is, according to the present invention, a foaming bath agent composition containing a carbonate, an organic acid and a binder is formed so that the weight of one particle or piece is 2.5 g or less and the specific gravity thereof is 2.0 or less. The present invention provides a surface foaming type bath agent.

In the present specification, the surface-foaming type bath agent means that the surface of the bath hot water is foamed and dissolved on the surface of the bath hot water immediately after the bath hot water is charged, or even once immersed in the bath hot water within 1 minute, preferably within 30 seconds. It refers to a type of bath agent that floats on the surface of the surface and foams and dissolves.

The surface effervescent bath agent of the present invention comprises a carbonate and an organic acid, which are conventionally known as components of effervescent bath agents, to which a binder is added. It is prepared by molding into granules having a weight of 2.5 g or less and a specific gravity of 2.0 or less.

As a means for preparing such a molded product, various methods can be adopted. As an example, a foaming bath agent composition containing a carbonate, an organic acid and a binder is 0.02. Method of pressing at a pressure of about 5 t / cm ^{2 and} crushing if necessary, suspending the foamable bath agent composition in an organic solvent, heating and drying on a drum to remove the solvent, and crushing if necessary And a method of molding with a briquetting machine.

The briquette shape in the present invention includes pillow shape, lens shape, almond shape, prism shape and the like. Further, the plate shape includes a disk shape, a donut plate shape, a diamond plate shape, a triangular plate shape and the like.

Among the foaming bath agent compositions used in the present invention, the foaming components are carbonates and organic acids. Oxygen bubbling occurs even with sodium percarbonate,
The foaming power is weak, and the effect of floating on the surface of the bath cannot be expected. Further, since active oxygen is generated, there remains a problem in terms of safety.

The carbonate used as the foaming component may be any pharmaceutically acceptable carbonate such as sodium hydrogen carbonate, sodium carbonate, sodium sesquicarbonate, etc., but is not particularly limited, but sodium hydrogen carbonate is used. Is preferable, about 5 to 60%, especially 1 in the total bath composition.
It is desirable that the content be 0 to 40%.

This carbonate has a fine particle size, for example, a median particle size of about 50 to 300 μm,
Particularly, those having a thickness of about 50 to 200 μm are preferable. In particular, when sodium hydrogencarbonate was blended under the above conditions, not only was it easy to float, but the foaming power immediately after charging was also excellent.

On the other hand, examples of the organic acid used in combination with the carbonate include succinic acid, malic acid, citric acid, tartaric acid and fumaric acid. 7-60% of these organic acids in the total composition
It is preferable that the amount is blended, especially about 10 to 50%.

The amount of the carbonate and the organic acid used may be such that carbon dioxide is generated enough for the particles to float on the surface of the bath water, and the number of gram equivalents involved in the reaction (reaction equivalent) with respect to the total composition. ) Is 0.2 or more, and particularly preferably 0.4 or more. In the present specification, the reaction equivalent is obtained by first calculating 1 gram equivalent of carbonate and organic acid from the following formula: 1 gram equivalent = (molecular weight) / (valence) Number of gram equivalents = (100g x composition ratio)
Calculate the number of gram equivalents involved in the reaction of carbonate and organic acid from / (1 gram equivalent), and obtain the number of gram equivalents, whichever is smaller, and calculate the amount of components that actually contribute to carbon dioxide gas foaming. It is shown.

Further, as a binder, casein, sodium carboxymethyl cellulose, water-soluble gelatin, pectin, starch, methyl cellulose, ethyl cellulose, sodium alginate, polyvinyl alcohol, polyvinylpyrrolidone, polyvinyl methyl ether, polyethylene glycol, karaya gum, locust bean gum, Tragant gum, carrageenan, carboxyvinyl polymer, acacia gum, agar, dextrin, cyclodextrin, sorbitol, sugar such as reduced maltose starch syrup, water-soluble polymer, urea, etc., any of the binders that can be used for manufacturing a solid foaming bath agent Can be used.
Of these, dextrin, urea, sorbitol, and reduced maltose syrup are preferable in view of moldability and solubility.

The content of the binder is generally 2 to 80%, preferably 5 to 70%, particularly preferably 10 to 60% in the total composition. If the blending amount of this binder is too small, breakage and abrasion are likely to occur during the transportation of the product, while if it is too large, a sufficient amount of carbonate and organic acid for foaming may not be blended.
