Description

 Description Electrolyzed water and method for producing the same Technical Field

 The present invention relates to electrolyzed water and a method for producing the same. More specifically, the present invention relates to electrolyzed water useful for skin care obtained by electrolyzing a L-ascorbic acid aqueous solution to which a predetermined amino acid is added, and a method for producing the same. Background art

 L-ascorbic acid is ionized in water by the dissociation of the 2nd and 3rd hydroxyl groups in the chemical structure. Electrolysis by applying a voltage to an aqueous L-ascorbic acid solution is a well-known technique (see, for example, Japanese Patent No. 3 60 2 7 7 3).

 When the L-ascorbic acid aqueous solution is electrolyzed, hydrogen ions and ascorbate ions generated by dissociation of ascorbic acid in water move toward the opposite electrodes. At the same time, water as a solvent is electrolyzed, and oxygen and hydrogen ions are generated by an oxidation reaction on the anode surface, and hydrogen and hydroxide ions are generated by a reduction reaction on the cathode surface.

Hydrogen ions and ascorbate ions generated by dissociation of ascorbic acid react with ions generated by electrolysis of water at the respective electrodes to form electrolytic products. That is, ascorbate ion reacts with H ⁺ produced by water oxidation on the anode to form ascorbate. On the cathode surface, water is produced by the reaction of hydroxide ions and hydrogen ions produced by the reduction of water. Oxygen generated on the anode surface and hydrogen generated on the cathode surface exist in water as dissolved oxygen or dissolved hydrogen.

In general, when a water-soluble substance dissolves in water, it depends on the state of the solvent. It is known that the solubility characteristics of Even when the same water is used as a solvent, the interaction between the water-soluble substance and water changes depending on conditions such as temperature, pressure, and external force. As a result, the solubility characteristics of the water-soluble substance also change.

 Under certain conditions, the electrolyte aqueous solution increases the entropy of the solution by electrolysis, and becomes more energetic than the steady state. As a result, the function as a solvent is activated, and the dissociation degree of water itself tends to increase. Electrolyzed water obtained by electrolyzing an aqueous electrolyte solution changes the conformation of water molecules surrounding the solute as the degree of water dissociation increases. For this reason, several reports have revealed that the dissolution rate of solutes increases and the degree of dissociation of low-dissociation substances increases.

 In the electrolysis of ascorbic acid aqueous solution, the solvent water is activated under the influence of electrolysis. Changes in the structural characteristics of water increase the degree of dissociation of ascorbic acid, which has the effect of promoting solubility. There is also a change in the interaction between water and the solute ascorbic acid. That is, it is considered that a characteristic change that increases the reactivity of ascorbic acid itself is brought about.

 The present inventors paid attention to these actions in the electrolysis of ascorbic acid aqueous solution, and conducted various studies to obtain electrolyzed water retaining this ability. As a result, when an aqueous solution of relatively low concentration of ascorbic acid alone is electrolyzed without using an inorganic electrolyte such as a water-soluble metal salt as an electrolysis aid, an anode that retains the ability to disproportionate super radicals. It was discovered that side electrolyzed water can be obtained, and a patent has already been obtained (Patent No. 3 60 27 7 3 (Claim 1)). Disclosure of the invention

The electrolyzed water of the above ascorbic acid aqueous solution promotes emulsifying action on the skin surface when touched to the skin due to a change in characteristics due to electrolysis and enters the skin. It has been confirmed that the ascorbic acid has improved permeability. Since ascorbic acid permeating the skin itself acts as a strong reducing agent, it has also become clear that when this electrolyzed water is applied to the skin, it exhibits a high whitening effect.

 However, the electrolyzed water of an ascorbic acid aqueous solution may cause irritation and a feeling of tension when applied to the skin, which may cause a problem in use. Moreover, there is no effect | action which improves the moisture retention of skin.

 The present inventor exhibits various effects on the skin when nonionic substances and ampholytes are added to ascorbic acid electrolyzed water by utilizing changes in physical properties due to electrolysis, particularly improved solubility. I thought that could be expected.

 An object of the present invention is to obtain electrolyzed water having a moisturizing effect in addition to a whitening effect by ascorbic acid by electrolyzing an amino acid substance having high affinity for a living body simultaneously with ascorbic acid in water. And As a result of the study, the present inventors conducted electrolysis of an aqueous solution of ascorbic acid or a derivative thereof to which a predetermined amino acid was added, so that the conventional ascorbic acid electrolyzed water is provided in addition to the whitening effect. The inventors have found that electrolyzed water imparted with moisture-retaining properties and skin quality-improving effects that have not been obtained, and have completed the present invention.

 The present invention is described below.

[7] Electrolyzed raw water containing water-soluble inorganic salt in an amount of less than 0.1 mM, trimethylglycine or L-hydroxyproline in an amount of 0.05 to 0.8 mass%, and L-ascorbic acid or a derivative thereof in an amount of 1 to 50 mM. It was fed into the continuous circulation type non-membrane electrolysis cell at a flow rate 5~ 3 0 0 0 m 1 / min, continuously degrades electricity electrolytic current density 0. 0 0 3~ 0. 0 8 a / cm 2 [3 ] The manufacturing method of the electrolyzed water of description. The electrolyzed water of the present invention is obtained by electrolyzing raw electrolyzed water containing a predetermined amino acid using an L-ascorbic acid derivative as an active ingredient and an electrolysis assistant. This electrolyzed water has the whitening effect of L-ascorbic acid and can be used as a cosmetic with excellent moisture retention. The ascorbic acid and amino acid added to the electrolyzed raw water are safe for the human body, and the safety of the electrolyzed water of the present invention produced by electrolyzing the electrolyzed raw water is extremely high.

Amino acids themselves are hardly involved in electrolysis, but the effect of improving the solubility of amino acids is caused by changes in the interaction between the solvent and the solute generated in the electrolysis process of the raw water. Due to this effect and factors such as dissolved oxygen present in the electrolyzed water, a high moisturizing effect can be obtained when the electrolyzed water of the present invention is applied to the skin.

BEST MODE FOR CARRYING OUT THE INVENTION

 The content of L-ascorbic acid or a derivative thereof in the electrolyzed water of the present invention is:! ˜50 mM, preferably 2 to 20 mM. If the concentration of L-ascorbic acid is less than 1 mM, the whitening effect of electrolyzed water will be insufficient, and the electrolysis will have low conductivity, making electrolysis difficult. When it exceeds 50 mM, a sticky feeling is felt when the obtained electrolyzed water is applied to the skin.

Examples of the L-ascorbic acid derivative may include sodium ascorbyl phosphate and magnesium ascorbyl phosphate. Examples of amino acids blended in electrolyzed water include known amino acids that are usually blended in cosmetics and the like. From the standpoint of preventing skin irritation caused by L-ascorbic acid and imparting high moisture retention to electrolyzed water, It is preferable to use syn (so-called betaine) or L-hydroxyproline.

 The blending amount of these amino acids in the electrolyzed water is 0.05 to 0.8 mass%, preferably 0.08 to 0.3 mass%. When the blending amount in the electrolyzed water is less than 0.05% by mass, the effect of imparting moisture retention to the electrolyzed water is not sufficient, and when it exceeds 0.8% by mass, a sticky feeling is strongly felt and a feeling of use is felt. descend.

 As an amino acid, a mixture of trimethylglycine and L-hydroxyproline may be added to the electrolyzed water. In that case, the blending amount is 0.05 to 0.8 mass% in total.

 Hereinafter, the method for producing electrolyzed water of the present invention will be described with reference to FIG. FIG. 1 is a schematic configuration diagram showing an example of an electrolysis apparatus used for producing electrolyzed water of the present invention.

 In FIG. 1, 2 is an electrolytic raw water tank in which an electrolytic aqueous solution (electrolytic raw water) 4 is stored.

 The electrolyzed raw water 4 comprises L-ascorbic acid or a derivative thereof in an amount of 1 to 50 mM, preferably 2 to 20 mM, and trimethylglycine or L-hydroxyproline in an amount of 0.05 to 0.8% by mass, preferably 0.08 to 0.3. 3% by mass is contained.

 It is desirable that the raw electrolytic water 4 does not substantially contain an electrolyte such as a water-soluble inorganic salt other than L-ascorbic acid or a derivative thereof. The content of the water-soluble inorganic electrolyte is preferably not more than 0.1 mM, particularly preferably not more than 0.02 mM, in total for each water-soluble inorganic electrolyte.

As a method for preparing such electrolyzed raw water 4, L-ascorbic acid or a derivative thereof and trimethyldaricin or L monohydroxyproline are dissolved in distilled water or purified water (pure water) such as deionized water within the above concentration range. The method of doing is illustrated. In FIG. 1, 6 is a pump interposed in the electrolyte aqueous solution supply pipe 8. By operating the pump 6, the aqueous electrolyte solution 4 is sent to the continuous flow type diaphragm electrolyzer 10 through the supply pipe 8. The flow rate of the aqueous electrolyte solution 4 supplied to the non-diaphragm electrolyzer 10 by the pump 6 is about 5 to 300 m / min, but preferably 50 to L0 00 m 1 in, more preferably Is from 5 0 0 to 1 0 0 0 ml l Zm in.

 The diaphragm electrolyzer 10 has a pair of electrodes 12 a and 12 b facing each other inside. The pair of electrodes 1 2 a and 1 2 b are disposed at a predetermined interval, and the interval is 2 to 0.05 mm, preferably 1.5 to 0.1 mm. When the distance between the electrodes exceeds 2 mm, mixing of the positive electrode side electrolyzed water and the negative electrode side electrolyzed water generated by electrolysis becomes insufficient.

 The electrodes 1 2 a and 1 2 b are made of an electrochemically inactive metal material. As the electrode material, platinum, a platinum alloy or the like is preferable.

 16 is an electrolytic power source, and its positive terminal and negative terminal are connected to both electrodes 1 2 a and 1 2 b by wirings 18 and 20, respectively. The polarities of the power applied to each electrode are switched at predetermined time intervals. By switching the polarity of the applied power at predetermined time intervals, the negative electrode side electrolyzed water and the anode side electrolyzed water are alternately generated in a pair of electrodes, so that the anode side electrolyzed water and the cathode side electrolyzed water are separated from each other. It is mixed efficiently. The polarity switching time interval is preferably 2 to 120 times, and more preferably 120 to 600 times. In addition, it is possible to effectively prevent the scale from adhering to the electrode by switching the polarity.

 The electrolyte aqueous solution 4 sent to the diaphragm electrolytic cell 10 through the electrolyte aqueous solution supply pipe 8 is electrolyzed in the diaphragm electrolytic cell 10.

The amino acid ion that is an ampholyte is not affected by the electric field within a short period of time, and almost no amino acid ion migration is observed. No matter what part of the electrolyzed water is collected, its distribution is almost constant. Electrolytic current density is, 0. 0 0 3~ 0. 0 8 AZ cm 2 are preferred, 0. 0 1~ 0. 0 3 AZ cm 2 is particularly preferred. When the electrolysis current density is less than 0.0 3 AZ cm ² , the dissolved oxygen amount and dissolved hydrogen amount in the electrolyzed water cannot be made higher than the electrolyzed raw water. If it exceeds 0.08 A / cm ² , the oxidation of L-ascorbic acid accelerates, the amount of dehydroascorbic acid generated increases, and the possibility of becoming oxidized L-ascorbic acid increases. .

 By electrolysis as described above, the anode side electrolyzed water and the cathode side electrolyzed water generated during electrolysis in the electrolytic cell are naturally mixed. The mixed electrolyzed water in which both electrolyzed waters are mixed is continuously taken out through the mixed electrolyzed water discharge pipe 22.

 Note that an electrolytic cell in which a diaphragm is formed between both electrodes 12 a and 12 b may be used as the electrolytic cell 10. As a diaphragm, what is conventionally used as an electrolytic membrane, such as an ion exchange membrane and an uncharged membrane, can be used as appropriate.

 In the above description, the electrode is a pair. However, the present invention is not limited to this, and a plurality of electrode pairs may be provided in the electrolytic cell to increase the electrolysis efficiency. Furthermore, it is not necessary to switch the polarity of power.

 The electrolyzer used when producing the electrolyzed water of the present invention is not particularly limited, and any electrolyzed water producing apparatus conventionally used can be used. In other words, any type can be used regardless of the size of the electrolytic device and the presence or absence of a diaphragm in the electrolytic cell.

 Furthermore, in the above description, it was taken out as mixed electrolyzed water in which anode side electrolyzed water and cathode side electrolyzed water were mixed. However, the present invention is not limited thereto, and anode side electrolyzed water and cathode side electrolyzed water are taken out separately and used separately. You may do it. In this case, it is reasonable to switch the polarity of the power applied to the electrode.
