Description

The present invention is an additive for making a simulated hot spring water quality in the case of bath use in domestic water such as tap water, groundwater, etc. It is an additive for the purpose of characterizing.

The hot spring feeling referred to here is a feeling at the time of bathing and after bathing, and is a feeling at the time of entering the hot spring and after bathing.
Recently, it has become possible to consider physiologically from the viewpoint of the recognition and memory of brain objects, information processing of the brain for movement, and the higher-order mechanisms of the brain.
From the conceptual point of view of the higher-order functional system of the brain, it is important to confirm the reference value information based on the "hot spring method" and to recognize the location of the hot spring, the environment, etc. Be an element.
Alternatively, while the feeling of feeling by bathing the five senses has been demonstrated, it is possible to present the sense of satisfaction from the feeling of warmth and the feeling of relief from bathing as well as the satisfaction from the feeling of comfort after bathing as a bodily sensation through hot springs. it can.

The composition component of the present invention contains an alkaline inorganic component and an organic polyvalent carboxylate that are approximate to natural hot springs, so that the alkaline component has a pH of 9 to 11, and the softening action of the hardness component by the organic polyvalent carboxylate. Works, and it has the feature that an excellent smooth feeling can be obtained in the sense of the epidermis of the human body ・
In particular, this agent is characterized by obtaining the same feel as a hot spring by converting the water quality to a hot spring, so the category is classified as a hot spring agent.

It is effective to use various herbal medicines, trace amounts of fragrances, pigments, and colorants as a supplement to the bathing agent of the present invention.

The alkaline inorganic component of the additive of the present invention is any one of sodium hydrogen carbonate, sodium carbonate, sodium sesquicarbonate (monosodium dihydrogen trisodium dihydrate), potassium hydrogen carbonate, potassium carbonate, potassium sesquicarbonate, etc. By blending carbonate as a simple substance or a mixture thereof, the concentration is adjusted so that the pH value is in the range of 9 to 11 in a hot water bath at the time of bathing.
These inorganic components are applicable to both anhydrous salts and salts with crystal water.

Further, in addition to the alkaline inorganic component, sodium or potassium salt of an organic polyvalent carboxylic acid having two or more carboxylic acid groups in one molecule is used in a hot water bath at the time of 0.0005 to 2%.

This agent adds effects by adding other bathing agents, and is also effective for use as a supplement for bathing agents themselves.
As herbal supplements, various herbal medicines, trace amounts of fragrances, pigments and colorants are used.

Sodium bicarbonate, sodium carbonate, sodium sesquicarbonate, potassium bicarbonate, potassium carbonate, potassium sesquicarbonate as alkaline inorganic components of this additive are used because the carbonate is highly soluble in water, so the concentration can be adjusted. This is because, when these additives are used as an aqueous solution in advance, the storage stability is improved such that inorganic salt crystals do not precipitate in the cold season.
Since these inorganic component salts are frequently used as raw materials for daily necessities and industrial articles, they are excellent in economic efficiency.
Here, if calcium, magnesium, or the like is used as the metal ion of carbonate, it causes scale formation, and anionic surfactant soap deposits on the skin. It will adversely affect the warming effect of the rising.

Organic polyvalent carboxylates having two or more carboxylic acid groups in one molecule to be blended in this spring quality agent are specifically listed as follows: gluconic acid, citric acid, adipic acid, sebacic acid, malic acid, poly These are sodium salts and potassium salts of carboxylic acids such as acrylic acid and EDTA, and their organic derivatives are also effective.
The most preferable organic polyvalent carboxylic acid is sodium citrate, and the next preferable organic polymer carboxylate is sodium polyacrylate having an average molecular weight of 100 to 30 million, 0.00005 to 2% is used.

In the present invention, when used as an additive for hot water baths, when raw water contains hardness components such as calcium and magnesium, the hardness components are softened, and the scale adheres to the waterline of the bathtub, producing an insoluble fatty acid soap. And preventing the insoluble solidified material and the like from adhering to the skin.
Further, since the hardness component is softened by the alkaline inorganic component and the organic polyvalent carboxylate, the smoothness feeling and the warm bath effect are improved in the skin during bathing.

Bath salts containing a combination of carbonates, sodium sulfate, sodium chloride, pigments, and fragrances are currently commercially available and are known techniques.
Most of the conventional bath preparations contain sodium bicarbonate, and in addition to sodium sulfate and sodium chloride, it is a powdered bath preparation in which fragrances, herbal extracts, coloring agents, and clouding agents are mixed. is there.

The additive of the present invention is an additive for making a hot water bath more powerful pseudo hot spring water quality compared with conventional bath additives, and enhances the warm bath effect at the time of bathing using this. The purpose of the present invention is to make a hot spring feel appear, and the above-described conventional techniques differ from the spring quality agent according to the present invention in terms of the purpose and effect of the technique.
An object of the present invention is to reduce adverse effects on hot water baths, particularly hot bath effects, particularly in domestic water such as local tap water and groundwater with high hardness.
In the composition component, alkaline inorganic component close to natural hot spring, that is, any one of carbonates such as sodium bicarbonate, sodium carbonate, sodium sesquicarbonate, potassium bicarbonate, potassium carbonate, potassium sesquicarbonate, or a mixture thereof In addition to these, sodium salt or potassium salt of organic polyvalent carboxylic acid containing two or more carboxylic acid groups in one molecule contains sodium chloride and sodium sulfate as inorganic components similar to natural hot springs. It is intended to obtain an additive for bathing that contains hot spring water quality by containing.

The alkaline inorganic components of the spring material include sodium bicarbonate, sodium carbonate, sodium sesquicarbonate (trisodium dihydrogen carbonate), potassium bicarbonate, potassium carbonate, potassium sesquicarbonate, anhydrous salts,
Any salt with crystal water may be used.
At the same time, sodium chloride and sodium sulfate usually contained in natural hot springs are added to give a synergistic effect to the warm bath effect.

The spring material of the present invention is carried out at a high pH value of 9 or more compared with the conventional carbonate bath water.
In this case, when the ratio of the bicarbonate is increased, the pH of the hot water for bathing can become slightly alkaline near 9, and when the ratio of sodium carbonate and potassium carbonate is increased, the pH of the hot water for bathing is increased to about 9-11. Can be adjusted.
It was confirmed that the pH range having the highest warm bath effect was 9.5 to 10.5.
Exceeding pH 11 is not preferable because the force acting on the skin is too strong and there is a risk of skin damage.

The reason for using sodium and potassium as carbonate metal ions is to increase the solubility in water,
Since these salts are frequently used as raw materials for daily necessities and industrial articles, they are also economical.
Here, when calcium, magnesium or the like is used as the metal ion of the carbonate, it causes scale formation and deposition of the insolubilized anionic surfactant on the skin, causing a sensory adverse effect, This will adversely affect the warming effect of the bath.

Basically, carbonate is a component generally contained in hot springs.
By adding an organic polyvalent carboxylate to adjust the pH value to 9-11, the alkaline component broadens the sweat line of the human epidermis, and the sodium and potassium salts of the organic polyvalent carboxylic acid penetrate through the sweat line. However, it is considered that the warm bath effect during and after bathing is enhanced by stimulation of nerves in the epidermis.
In particular, the combination of carbonate and polyacrylic acid, represented by sodium carbonate, penetrates the human epidermis with a small amount of carbonate and adheres to the human epidermis, improving the moisturizing effect. By adhering to, it is possible to reinforce the warm bathing effect at the time of bathing and after bathing and further enhance the effect of making the hot spring feel appear.
