Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lotion used for cosmetic purposes and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, it is generally practiced to immerse a pack mat in a chemical-added aqueous solution prepared for facial treatment, bring it into close contact with the face, and use skin respiration and body pores to care for the skin. Known and widely used. In general, organic compounds such as loofah are often used as an additive component to the lotion, but the effects of these conventional lotions are not uniform due to individual differences in cortical characteristics, and rash It is not always fully satisfactory in preventing damage to the skin and skin.

[0003]

The cause of the above-mentioned skin damage and rash is caused by the fact that an aqueous solution containing the components which is considerably separated from the physiological water contained in the intracellular fluid of human skin is used for facial and facial cleansing. It is thought that it is because it is used for. In other words, human skin has a physiological action of water and gas in and out, and it is presumed that the above problems will occur when foreign substances are taken in.

Therefore, the present inventor has already taken advantage of the ionic activity of the alkaline water and acidic water when water is separated into alkaline water and acidic water by electrolysis and electropenetration to make a facial or facial cleansing. I am devising to get the effect.

In this research, the inventor of the present invention conducted electrolysis of general raw water (well water, tap water, etc.) by electrolysis and electroosmosis to obtain electrolyzed water of an aqueous solution containing specific potassium and magnesium content rather than alkaline water and acid water. It has been found that the above is more preferable in utilizing the ionic activity to exert a facial or face-washing effect (Japanese Patent Publication No. 60563).
Issue).

However, the conventionally proposed lotion is not always sufficiently satisfactory when comprehensively judging the feeling of use, water retention, moisturizing feel, and paste of makeup.

The present invention has been made in view of the above-mentioned points, and provides a lotion which is excellent in skin conditioning, cosmetic action, as well as a feeling of use, water retention, moisturization, and makeup paste, and a method for producing the same. That is the purpose.

[0008]

Means for Solving the Problems] To achieve the outline above object of the invention, lotion according to the invention,

It is characterized in that it is contained in the range of 0.5 g / lit and is composed of an aqueous solution having a pH range of 3 to 7.

Further, in the method for producing a lotion according to the present invention, in preparing the lotion, potassium or magnesium salts are mainly contained in a liquid whose pH is adjusted by passing all or part of the water to be treated through the cation exchange means. It is characterized by being prepared by adding an additive solution of

Further, the present invention also includes a method of regenerating and recycling the toner once used. That is, the present invention produces a mineral-containing skin lotion by adding an additive liquid mainly composed of salts of potassium and magnesium to a liquid whose pH is adjusted by passing all or part of the water to be treated to the cation exchange means, and further using it. The prepared lotion is returned to the lotion producing means again, and if necessary, the whole amount or a part thereof is passed through the cation exchange means of the lotion producing means to adjust the pH or to add potassium and / or magnesium. According to the method, the method for circulating and regenerating a lotion is characterized in that it is circulated in a circulation circuit for adjusting the pH and the mineral concentration within a predetermined range.

Further, in the present invention, an addition liquid mainly containing a salt of potassium and magnesium is added to a liquid whose pH is adjusted by passing all or part of the water to be treated in the cation exchange means, and further electrolyzed. The mineral-containing lotion is produced, and the lotion used is returned to the lotion-producing means again, and if necessary, potassium and magnesium are added, or an acid generated by electrolyzing all or part of the acid A method for recycling and regenerating a lotion is characterized by adding water to circulate it in a circulation circuit for adjusting the pH and mineral concentration within a predetermined range. DETAILED DESCRIPTION OF THE INVENTION The mineral-containing lotion according to the present invention has a concentration of potassium and magnesium close to that of intracellular fluid of the human body, potassium 3 to 10 g / lit, magnesium 0.
It is contained in the range of 1 to 0.5 g / lit and has a pH of 3 to 7.
It is characterized by comprising an aqueous solution in the range of.

When the potassium concentration is less than 3 g / lit and the magnesium concentration is less than 0.1 g / lit, irritation to the skin is too weak and the penetrating power is insufficient, which is not preferable. On the other hand, when the potassium concentration exceeds 10 g / lit and the magnesium concentration exceeds 0.5 g / lit, the skin irritation becomes too strong, the burden on the skin increases, and the tendency to feel heavy when applied increases. It is not preferable.

Examples of compounds that can be added as a source of potassium and magnesium components in the present invention include potassium lactate, potassium dihydrogen phosphate, potassium chondroitin sulfate, potassium hyaluronate, potassium aluminum sulfate, dipotassium glycyrrhizinate, and magnesium lactate. It is preferably used.

The above-mentioned potassium concentration and magnesium concentration in the present invention are concentrations based on the weight of potassium ion and magnesium ion, respectively.

The lotion according to the present invention is adjusted so as to be close to the potassium and magnesium concentrations in the intracellular fluid within the above concentration range. The concentration of the aqueous solution before treatment and the addition amount of the additive liquid depend on the treatment conditions. It should be noted that it is different.

In addition, the lotion according to the present invention is not only close to the concentration of potassium and magnesium in the intracellular fluid but also p
H tends to be acidic, and more preferably the absorption into the skin is further improved by activating water by electrolysis or the like.

As described above, the lotion p in the present invention is
It is important to adjust H in the range of 3 to 7, and if the pH is less than 3, the acidity is too strong, so that a tingling sensation is felt when applied to the skin. On the other hand, if it exceeds 7, the meaning of making the skin surface pH of the skin surface inclined to alkali becomes weakly acidic and the astringent effect for tightening the skin also disappears, which is not preferable. .

The above pH range can be adjusted by electrolysis and / or cation exchange. In the most preferred embodiment of the present invention, the pH range can be adjusted by cation exchange and electrolysis.

The lotion according to the present invention may further contain at least silver ions generated by an electrolytic cell having a silver electrode as an anode. By dissolving the silver ions thus generated in the lotion,
Due to the bactericidal effect of silver ions, various bacteria attached to the skin can be removed, and the propagation of various bacteria in the lotion can be suppressed.

Furthermore, in a preferred embodiment of the present invention, a chloride ion species such as hydrochloric acid and / or chloride salt can be added to the additive liquid. Since chlorine ions become hypochlorous acid which exhibits a bactericidal effect by electrolysis, the bactericidal effect on the skin can be obtained and the preservability of the lotion is improved. The difference from the above-mentioned sterilizing effect of silver ions is
Hypochlorous acid loses its bactericidal power by being exposed to organic substances and oxygen, so it returns to water after sterilization, whereas silver ions have their own bactericidal power, so the state of ionic The sterilizing power is maintained until it disappears (due to a change in pH, etc.), so that the sterilizing power lasts for a relatively long time.

Furthermore, the skin lotion according to the present invention may optionally contain magnesium ascorbyl phosphate (whitening agent), U-jelly (trade name), sodium chondroitin sulfate, pyrrolidone, sodium carboxylate, if desired.
Ingredients such as (humectant), pehalin, yoquinin and the like can be added as additional additive ingredients, and the addition amount in this case may be considerably smaller than the amount usually used for beauty essences.

It can be seen that the skin is moisturized and the moisturizing feeling is maintained when it is packed with the lotion according to the present invention. In addition, significant effects are also recognized for the action of conditioning the skin such as increasing the whiteness of the skin. As described above, in the lotion of the present invention, the skin is adjusted, the cosmetic effect and the feeling of use,
Excellent in water retention, moisturizing and makeup paste.
This is believed to be an unexpected effect of maintaining the potassium and magnesium concentrations in a relatively high range. Further, since the mineral concentration was controlled within the above range, immediate effect was also observed, which is considered to be also an effect associated with setting the potassium and magnesium contents to high concentrations.

In applying the lotion according to the present invention,
First, with alkaline water having a pH of 10.5 or less generated on the cathode side by electrolysis, the skin is softened by washing the face or packing with a lotion mask for about 10 minutes, and then using the lotion (acidic lotion) of the present invention. It is desirable to pack with a lotion mask. Soft skin lotion such as Bertz water is a lotion containing potassium hydroxide as a main component, and alkaline water produced by this electrolysis contains potassium hydroxide and so on. Have the effect of.

The lotion according to the present invention can be prepared by adding an additive solution mainly composed of potassium and magnesium salts to a solution of which the pH is adjusted by passing all or part of the water to be treated through the cation exchange means. it can.

Further in a preferred embodiment of the present invention,
It is also possible to prepare a lotion by adding an additive solution containing potassium and magnesium salts as a main component to a solution of which pH has been adjusted by passing all or part of the water to be treated through the cation exchange means and further electrolyzing.

The above-mentioned electrolysis can also be carried out according to a conventionally known method, and for example, according to the present applicant, J.
The apparatus and method disclosed in the publication 0-10712 can be used. In a preferred embodiment of the present invention, it is particularly preferable to use a three-tank type electrolytic cell having a double partition wall described later.

The preparation of the lotion by electrolysis as described above is effective in further improving the permeability to the skin because the water clusters are reduced by the electrolysis, and the redox potential is increased. As it decreases, it can prevent skin aging. As is clear from the results of Examples described later, in the present invention, a synergistic effect can be obtained by the combined use of the above-mentioned addition of the mineral component in a specific concentration range and electrolysis.

Furthermore, the present invention also includes a method of regenerating and recycling the toner once used.

That is, one embodiment of the method for circulating and regenerating the lotion according to the present invention is to adjust the pH by passing all or part of the water to be treated through the cation exchange means, and add the additive solution mainly containing salts of potassium and magnesium to the solution. In addition, mineral-containing lotion is produced, and the used lotion is returned to the lotion producing means again, and if necessary, the whole amount or a part of the cation exchange means of the lotion producing means is passed to adjust the pH. Or adding potassium and / or magnesium to circulate it in a circulation circuit for adjusting the pH and the mineral concentration within a predetermined range.

In still another embodiment, an cation exchange means is added with an additive solution mainly containing potassium and magnesium salts to a solution of which pH is adjusted by passing all or part of the water to be treated, followed by electrolysis. The mineral-containing lotion is produced, and the lotion used is returned to the lotion-producing means again, and if necessary, potassium and magnesium are added, or an acid generated by electrolyzing all or part of the acid It is characterized in that by adding water, it is circulated in a circulation circuit for adjusting the pH and mineral concentration within a predetermined range.

Further, in a preferred embodiment of the present invention, by treating in the above-mentioned lotion production step or circulation step through an electrolytic cell having a silver electrode as an anode,
A lotion containing silver ions can be produced. The effect of the silver ions dissolved in this way is as described above.

Furthermore, as described above, in the preferred embodiment of electrolysis in the present invention, it is particularly preferable to use a three-cell type electrolytic cell having a double partition wall. In other words, this type of electrolytic cell has an anode chamber (innermost cell) in which a positive electrode is arranged in the central part of the electrolytic cell and a negative electrode in the outer circumference (outer cell) of this anode chamber. The cathode chamber and the cathode chamber are formed, and the anode chamber and the cathode chamber are separated by two partition walls. The area surrounded by the two partition walls constitutes an inner tank (intermediate tank). As described above, water is contained in the cathode chamber of the electrolytic cell in which two diaphragms are disposed between the positive electrode and the negative electrode, and water, potassium and magnesium salts are contained in the anode chamber and the cell surrounded by the two diaphragms. Electrolyzing by adding an additive solution mainly containing is excellent in terms of improving the production efficiency of cosmetic lotion and reducing the cost. That is, by using such a double partition electrolytic cell, it is not necessary to add a mineral component to the cathode chamber, the chemical solution can be saved, and an excessive rise in pH on the alkaline side can be prevented. You can

Further, in the present invention, zinc lactate may be further added to the additive solution for the purpose of suppressing skin irritation, but at this time, aldehyde may be produced in the vicinity of the anode to give offensive odor. Here, by using the electrolytic cell having a double partition wall, the aldehyde-containing water generated near the anode can be easily removed.
