Abstract

PURPOSE: To remove chlorine contained in tap water in a bathtub by using a dechlorinating agent prepared by mixing a power of ascorbic acid or sodium ascorbate being a main agent and a powder of citric acid being a stabilizer in an arbitrary mixing ratio under stirring and granulating the resulting mixture. CONSTITUTION: A powder of citric acid is mixed with a powder of ascorbic acid or sodium ascorbate being a main agent as a stabilizer and the resulting mixture is granulated. The wt. mixing ratio of ascorbic acid or sodium ascorbate being the main agent and citric acid being the stabilizer is set to 100:0.5-3.0. By charging a small amt. of this dechlorinating agent in tap water stored in a bathtub, chlorine in tap water can be immediately removed and dechlorinating effect is continued even when tap water is poured more.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dechlorinating agent for bathtubs, which stores chlorine in tap water and then dechlorinates it.

[0002]

2. Description of the Related Art Heretofore, a dechlorinating agent for a bath, which stores chlorine in tap water in a bath and then dechlorines it, has not been put to practical use.

[0003]

Chlorine in tap water is currently superior to any other for the purpose of sterilization. Needless to say, it is necessary to contain chlorine up to the tap of the water supply, but it is ideal that chlorine is finally removed at the tap. Currently, many drinking water purifiers with dechlorination functions have been developed for drinking, and meet the needs accordingly. In addition, recently, the dechlorination effect is enhanced by using a filter having a dechlorination effect on the shower head.

The harmful effect of chlorine on the human body is that when a dilute chlorine solution is exposed to the whole body, a part of it reacts with skin oil to produce a chlorine compound, which is absorbed into the body. Continuous immersion in water containing chlorine promotes skin aging and is as harmful as exposure to UV light. The chlorine gas is diffused into the air as the water warms, and the inside of the bathroom becomes filled with chlorine gas, which damages the respiratory organs. Something like that.

Therefore, taking a bath containing tap water has the problem of causing the above-mentioned harm to the human body.

The present invention relates to a dechlorinating agent for bath tubs, which aims to solve the above-mentioned conventional problems.

[0007]

The present invention has ascorbic acid or sodium ascorbate powder as a main ingredient,
The problem was solved by adopting a means in which powder of citric acid was used as a stabilizer, and the mixture was stirred and mixed at an arbitrary mixing ratio and then granulated.

[0008]

According to the present invention having the above-mentioned constitution, chlorine in tap water in the bath is dechlorinated by an oxidation-reduction reaction of ascorbic acid or sodium ascorbate which is the main ingredient.

[0009]

EXAMPLE The present invention is a dechlorinating agent for baths which removes chlorine in tap water by a chemical reaction (oxidation-reduction reaction), and uses ascorbic acid or sodium ascorbate powder as a main agent, and citric acid as a stabilizer. Mix the powders,
It is characterized by granulating.

The embodiments of the method of the present invention are described in detail below. First, of the raw materials constituting the dechlorinating agent for baths of the present invention, ascorbic acid, which is one of the main ingredients, is white or pale yellowish crystals or It is powdery, odorless, has a sour taste, and is unstable to alkalis, but stable to weak acids.

Further, of the raw materials constituting the dechlorinating agent for bathtubs of the present invention, the other main ingredient, sodium ascorbate, is white or pale yellow particles, fine particles or crystalline powder, and is odorless and slightly salty. Have. It has the characteristics that it is stable in a dry state, unstable in a hygroscopic state, and more soluble in water than ascorbic acid.

Further, citric acid, which is a stabilizer which constitutes the dechlorinating agent for bath according to the present invention, is a colorless transparent crystal, grain or lump, or white crystalline powder, or colorless powder,
It has the characteristic of having a strong acidity.

The dechlorinating agent for bathtubs of the present invention comprises a powder of ascorbic acid or sodium ascorbate having the above characteristics as a main agent, and a powder of citric acid as a stabilizer.
It is manufactured by stirring and mixing at an arbitrary mixing ratio, and then granulating.

The mixing ratio of ascorbic acid or sodium ascorbate, which is the main agent, and citric acid, which is the stabilizer, does not need to be particularly limited, but preferably 100% by weight of the mixed powder of the main agent and the stabilizer. 0.5 ~
A blending composition of 3.0 is recommended, and it is particularly preferable that the mixed powder of the main agent and the stabilizer is 100: 1 in a weight ratio.
It is recommended that the compounding composition of

The dechlorinating agent for baths according to the present invention utilizes the redox power of ascorbic acid represented by the chemical formula 1 or the redox power of sodium ascorbate represented by the chemical formula 2 in tap water (in the bathtub). ) Decomposing the residual chlorine dissolved in it and converting it to chloride (chloride ion) enables dechlorination.

[0018] Ascorbic acid and sodium ascorbate dissolve faster in sodium ascorbate due to the difference in redox power. However, both have the same dechlorination effect.

The reason for mixing citric acid as a stabilizer with ascorbic acid or sodium ascorbate, which is the main agent, is to maintain the stability of ascorbic acid or sodium ascorbate remaining in the bath. That is, the ability to decompose ascorbic acid or sodium ascorbate is maintained until the tap water is added to the bath to maintain the dechlorination effect.

The action of the dechlorinating agent for bath tubs of the present invention will be described. 1 g of the dechlorinating agent for bath tubs of the present invention, which is obtained by a particularly preferable composition of the main agent and the stabilizer, is added to 200 l of tap water stored in the bath. Immediately, a sufficient dechlorination effect was recognized by the addition. Further, the pH before the addition was 7.06, while the pH after the addition was 6.98.
Showed weak acidity. That is, since the pH of tap water in the bathtub is kept weakly acidic, it has a body rinse effect and is also excellent in beauty.

[0021]

Since the present invention is as described above, chlorine in tap water can be immediately dechlorinated by adding a small amount of the bath dechlorinating agent of the present invention to tap water stored in the bath. The dechlorination effect continues even if tap water is added, and it is not necessary to add new water each time tap water is added. Further, since the dechlorinating agent for bathtubs of the present invention is granulated,
Even when it is put into the bathtub, it can be quickly put into the container without staying in a container such as a bag. Furthermore, by adding the dechlorinating agent for bathtubs of the present invention to tap water in the bathtub, p
It keeps H weakly acidic, is excellent in body rinsing effect and beauty effect, and can prevent harm of chlorine to human body.
