Description

TECHNICAL FIELD The present invention relates to a bathing agent which emits a plosive sound when dissolved in a bath water and generates a gas by an acid-base reaction.

<Prior art> Conventional bath agents include an inorganic salt bath agent, a medicinal plant bath agent, or bath oil blended with mineral oil, as well as an effervescent bath that generates an acid-base reaction to generate carbon dioxide gas when dissolved. Agents and the like are known.

However, in the conventional effervescent bath additive, since carbon dioxide gas is generated only by the acid-base reaction, the amount of the generated gas dissolved in the bath water is limited, and a large amount of gas scatters into the air. However, the current situation is that the effect of the effervescent bath agent is not sufficient to promote blood flow by gas. In addition, the massage effect when bathing due to gas generation is not sufficient, and the sound when carbon dioxide gas is generated is low.

<Problems to be Solved by the Invention> Therefore, an object of the present invention is to produce a plosive sound at the time of dissolution, which can be enjoyed aurally, and a gas flow promoting effect by the generated gas can be obtained. It is to provide a bath agent that exhibits a massage effect and the like.

Another object of the present invention is to provide a bathing agent in which a large amount of generated gas is dissolved in a bath, and various effects associated with gas generation are effectively obtained.

<Means for Solving the Problems> According to the present invention, a raw material component containing a saccharide and dextrin is mixed with water, heated, dehydrated, and then solidified by cooling,
Further crushing, then the obtained powder is housed in a pressure vessel, high pressure gas is introduced to pressurize, and after heating and cooling, it is cooled to normal pressure, crushed, and pulverized. There is provided a bathing agent characterized in that it comprises a saccharide-containing solid that emits a plosive sound when dissolved and a base that generates a gas by an acid-base reaction.

The present invention will be described in more detail below.

The bathing agent of the present invention contains a saccharide-containing solid obtained by a specific production method using a specific raw material component, and a base that generates a gas by an acid-base reaction.

The saccharide-containing solid substance contains saccharides and dextrin as essential raw material components. Examples of the saccharides include sucrose, maltose, maltitol, mannitol, starch syrup, sorbitol, pentaerythritol, glucose, lactose, xylit, xylose, galactose, raffinose, mannose and reduced maltose. Particularly preferably, it is desirable to use raw material components containing 3-55 parts by weight of sucrose, 15-55 parts by weight of lactose and 15-70 parts by weight of dextrin.

Other raw materials that can be used in addition to the sugars and dextrins include, for example, cyclodextrin; corn starch, starches such as wheat flour, agar, casein, gelatin, pectin, sodium pectate, sodium alginate, methyl cellulose, ethyl cellulose, carboxy. Sodium methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, nitrocellulose, crystalline cellulose, polyvinyl alcohol,
Polyvinyl methyl ether, polyvinyl pyrrolidone, sodium polyacrylate, carboxyvinyl polymer,
Examples thereof include water-soluble polymers such as polyethyleneimine and polyethylene glycol.

The content ratio when the saccharide-containing solid is contained in the bath agent is not particularly limited, but in a weight ratio, the other bath agent base: the saccharide-containing solid is 6: 4. Is preferred.

In the present invention, to prepare the saccharide-containing solid,
First of all, it contains dextrin as a raw material component.
As a step, the raw material components and water are mixed and heated,
After dehydration, it is solidified by cooling and crushed. Next, as a second step, the obtained powder is stored in a pressure vessel such as a pressure cooker, and a high pressure gas such as carbon dioxide gas is introduced to pressurize, and after heating and cooling, the pressure is reduced to normal pressure. Crush,
It is produced by a method of making fine particles. At this time, the heating in the first step is preferably performed in the range of 100 to 160 ° C.
On the other hand, it is preferable that the amount of high-pressure gas enclosed in the second step is 0.1 ml or more in 1 g of the saccharide-containing solid, and the pressure at this time is 10 to 80 kg / cm ² , and the heating temperature is
The temperature is preferably 80 to 130 ° C. The particle size of the saccharide-containing solid obtained by further granulation is 0.01 to 20.0 mm, particularly 0.1 to 1
0.0mm is preferable.

The saccharide-containing solid obtained by such a preparation method is a saccharide-containing solid that is once solidified because the saccharides and dextrin that are raw material components are thickened in a pressure vessel and pressurized by high-pressure gas. High-pressure gas is dispersed and enclosed as air bubbles.

In the present invention, as a base that generates a gas by an acid-base reaction, a component used as a bathing agent that generates a gas by a normal acid-base reaction can be used. For example, carbonate components such as sodium hydrogen carbonate, sodium carbonate, sodium sesquicarbonate, malic acid, citric acid,
Examples thereof include bases containing organic acids such as succinic acid, fumaric acid and tartaric acid.

In the present invention, the bath salt base component other than the base that generates gas by the saccharide-containing solid and the acid-base reaction is particularly limited as long as it is usually used as a bath salt base. Examples thereof include inorganic salt components such as sodium chloride, enzymes, dyes, fragrances, polyhydric alcohols, and moisturizing components.

To prepare the bathing agent of the present invention, a method of mixing the saccharide-containing solid and a base that generates a gas by an acid-base reaction, and a method of mixing with another bathing agent base, if desired, A method of compression molding using a tableting machine to integrate the components, a method of forming a tea bag using a water-soluble or water-soluble packaging material after mixing the components, or the sugar-containing solid into a tablet form. After solidifying, a base material or the like which generates gas by the acid-base reaction may be coated around it to form a multilayer structure.

<Effects of the Invention> The bathing agent of the present invention contains a saccharide and a dextrin as raw material components, and contains a saccharide-containing solid obtained by a specific preparation method, and a base that generates a gas by an acid-base reaction, The gas generated by the acid-base reaction can be effectively dissolved in the bath water. Therefore, the active ingredient in the bath salt can be effectively permeated into the skin, and the generated gas can effectively stimulate the skin to enhance the blood flow promoting effect. Further, the saccharide-containing solid is obtained by a specific component and a specific production method, and thus has excellent stability over time during storage, and has a high sounding level of a plosive sound generated upon dissolution,
Since the ultrasonic waves are generated synchronously and the duration of the ultrasonic waves is long, in addition to the above effects, auditory enjoyment and whole body massage effects can be obtained when the ultrasonic waves are put into the bathhouse.

<Examples> The present invention will be described in more detail with reference to Examples and Comparative Examples, but the present invention is not limited thereto.

Example 1 30.0 parts by weight of sucrose, 30.0 parts by weight of lactose and 40 parts by weight of dextrin were heated and dissolved at 150 ° C. with a small amount of water, cooled, solidified and pulverized.

The same measurement as in Example 1 was performed on the obtained bath agent. The results are shown in Table 1 and Table 2, respectively.

From the results of Table 1, Comparative Example 1 containing a base that simply generates a gas by an acid-base reaction has a lower solubility in a bath water and a residual ratio over time as compared with Example 1 containing a saccharide-containing solid. It turns out that it is inferior to. Further, from the results of Table 2, it is understood that Comparative Example 1 is inferior to Example 1 in the way of warming the body, the purifying action, the massage effect and the like.

These are large bubbles generated by acid-base reaction in which the bathing agent of the present invention contains a specific saccharide-containing solid, burst stimulus associated with a burst sound generated when the solid is dissolved in bath water, and ultrasonic waves cause an acid-base reaction. It is considered that the gas of the above becomes micronized, promotes dissolution in the bath, and prevents scattering into the air.
