Description

[Detailed Description of the Invention] [Industrial Application Fields] The present invention can be used to easily and easily acidify the pH of a large amount of water or purified water, so it can be used as a lotion, or it can be used as a cleansing liquid or cosmetic. The present invention relates to a method and apparatus for producing a cosmetic liquid that can be used as a basic cosmetic liquid in a wide range of fields such as basic moisture.

[Prior Art] Conventionally, commonly used lotions and cleaning cosmetics include lotions and cleaning cosmetics that have been adjusted to be acidic in advance. The surface of human skin is acidic (PH4
, 5 to 6.5), and its near acidic P
Organic acids (e.g. citric acid, tartaric acid,
Lactic acid, etc.) is added to the lotion to make it acidic, and the acidic content gives an astringent effect to the skin surface, giving a pleasant stimulation to the skin.
A method for producing lotions and cosmetics suitable for oily skin, and a method for producing lotions and cosmetics in which natural plant liquids, ethanol, etc. are added to give a refreshing feeling to the skin are disclosed in the precedent application of this application. It is well known.

[Problems to be Solved by the Invention] By the way, in the conventional manufacturing method of this type of cosmetic liquid, organic acids and other additives are added to the lotion in order to bring the acidity of the lotion closer to the pH of the skin. However, if such organic acids or other additives are mixed,
When the above additives include water-insoluble additives, it is necessary to further mix in additives to disperse the water-insoluble components in water, so the number of types of additives is increasing. As a result, there was a problem in that the additives caused many unanticipated side effects.

The present invention changes the pH of a large amount of water or purified water to be close to the acidity of the skin, without adding any additives as in the past, thereby easily creating a cosmetic liquid suitable for the skin. It is an object of the present invention to provide a method for producing a cosmetic liquid and an apparatus therefor.

[Means for Solving the Problems] In order to achieve the above object, in the method for producing a cosmetic liquid of the present invention, "in the raw water flowing downward from the second part,
By directly contacting the combustion gas flowing from the bottom to the top, the carbon dioxide in the combustion gas is dissolved and mixed into the raw water, and P
The acidic cosmetic liquid has an H value within the range of 4.5 to 6.5.

In the above method, if the pH is adjusted by repeatedly directly contacting raw water with carbon dioxide in the combustion gas and directly contacting the mixture, a cosmetic liquid with a pH suitable for the acidity of the skin can be quickly produced. can be manufactured.

In addition, in the method for producing a cosmetic liquid of the present invention, a heat exchange chamber provided with a water sprinkler and a heat exchange layer is provided in the upper stage of the main body.
A combustion chamber facing the burner's combustion port is placed in the middle, and a liquid collection chamber is arranged in the lower part in a three-dimensional manner.

In addition, if the liquid collection chamber located at the bottom of the main body is connected to a liquid storage tank through a cooling sedimentation layer and a filter, impurities can be separated by precipitation.'' - The clear liquid is stored and stored in the liquid storage tank. be able to.

In addition, the cooling sedimentation layer and the water sprinkler inside the main body are connected via a circulating liquid supply pipe equipped with a pump, and the treated liquid is repeatedly brought into direct contact with the circulating combustion gas, making it easy to adjust the pH. You can adjust the acidity level by going to

[Function] Now, an equal amount of raw water (for example, tap water or spring water, etc.) is sprinkled from a water sprinkler onto the heat exchange layer installed in the heat exchange chamber, and at the same time, the burner is operated to burn the combustion gas. Spray it into the combustion chamber from the mouth.

Then, the raw water flows down evenly within the heat exchange layer while bending the wire, then passes through the combustion chamber and falls into the lower liquid collection chamber. On the other hand, the combustion gas flows uniformly through the heat exchange layer above the combustion chamber in the opposite direction to the flow of raw water, and is finally exhausted to the outside of the main body through the exhaust port.

Therefore, the raw water flowing downward from above and the combustion gas flowing upward from below come into direct contact many times during the flow and flame-up process, and as a result, they become hot water. Carbon dioxide gas contained in large amounts (approximately 13
% to 14%) is dissolved and mixed into the raw water.

As shown in the following, when a large amount of free carbon dioxide is dissolved and mixed into raw water, the raw water naturally becomes an acidic cosmetic liquid with a pH in the range of 4.5 to 6.5, and is used as a lotion. The liquid is changed into a liquid of suitable water quality, passed through the liquid collection chamber, and supplied to the cooling sedimentation layer from the main body, where impurities are separated by sedimentation.The supernatant liquid is then fed to a filter for filtration, and finally The purified cosmetic liquid is stored in a liquid storage tank and taken out as needed.

Therefore, the cosmetic liquid obtained through the above-described steps can be used not only as a lotion but also as a base moisture for other cosmetic products. In addition, when the pH of the cosmetic liquid obtained by the above method is adjusted, it is possible to easily achieve this by adjusting the carbon dioxide concentration in the combustion gas of the burner. By repeatedly supplying the stored cosmetic liquid to the water sprinkler inside the main body via the circulation pump and circulation liquid supply pipe to sprinkle water, it comes into direct contact with the combustion gas again, and the carbon dioxide in the gas is removed. can be dissolved and mixed in to increase the acidity to the required degree.

Moreover, the raw water is exposed to combustion gas (approximately 1
Because it comes into direct contact with the temperature (300°C), common bacteria such as E. coli are also sterilized, resulting in a sterile state. Therefore, there is no need to separately add ethanol or other disinfectants.

[Example] A cosmetic liquid manufacturing apparatus for carrying out the method of the present invention will be described with reference to the drawings.

In the drawing, 1 indicates that carbon dioxide gas in combustion gas is dissolved and mixed into raw water (tap water, spring water, or purified water) so that the pH is 4.
This cosmetic liquid manufacturing apparatus is capable of continuously manufacturing a cosmetic liquid having an acidic water quality within the range of 5 to 6.5, and is configured as follows. That is, a plurality of porous partition walls 5 are laid horizontally at appropriate intervals in the upper position of the hollow main body 2, which has a circular, square, polygonal, or other arbitrary cross-sectional shape. At the top of each porous partition plate 5, a heat exchange chamber 3 containing a heat exchange layer 4 made of a heat-resistant and corrosion-resistant material and a spongy heat-absorbing material 6 with high flame permeability placed thereon is arranged. ing.

The middle stage of the main body 2 is formed into a hollow combustion chamber 7,
A funnel-shaped liquid collecting chamber 8 with an open upper surface is provided in the lower part, and an exhaust port 9 is opened in the upper part of the main body 2. A water sprinkler 10 is installed at an upper central position in the heat exchange chamber 3, and the tip of a raw water supply pipe 11 is connected to the water sprinkler 10.

Further, a solenoid valve 12 is provided in the middle of the raw water supply pipe 11 to automatically supply and stop raw water (tap water, spring water, or purified water).

In one example of the main body 2 constituting the combustion chamber 7, a burner 13 for completely burning liquid fuel, gaseous fuel, or other fuel is installed horizontally, and the combustion port 14 of the burner 13 faces into the combustion chamber 7. Thus, the complete combustion gas can be evenly distributed from the combustion chamber 7 into the heat exchanger N4 arranged in the heat exchanger chamber 3. 7a is a water tank provided on the inner periphery of the combustion chamber 7.

On one side of the cosmetic liquid manufacturing apparatus 1 configured as described above, a cooling sedimentation tank 15 with an open upper surface, a filter 16 and a liquid storage tank I7 are installed in this order. The other end of the drain pipe 18 to which one end is connected is connected to the cooling settling tank 15 through a pump 19, and the supernatant drain pipe 20 connected to the upper side of the standing cooling settling tank I5 is connected to the filter I.
6. 21 is a connecting pipe that connects the filter 16 and the liquid storage tank 17. 22 is a circulation liquid supply pipe whose one end is connected to the cooling sedimentation tank 15, and the other end is connected to the water sprinkler IO, and the circulation pump 23 provided in the middle of the circulation liquid supply pipe 22 supplies the cooling sedimentation tank. The cosmetic liquid stored in the chamber 15 is sprinkled into the heat exchange chamber 3 through the water sprinkler 10 to bring it into direct contact with the combustion gas again, thereby dissolving and mixing carbon dioxide in the combustion gas to increase acidity and pH. Make adjustments.

[Effects of the Invention] Since the present invention includes the method and apparatus described above, it produces the effects described below.

Because the raw water flowing down from the top to the bottom is brought into direct contact with the combustion gas flowing down from the bottom to the top, the carbon dioxide contained in large amounts in the combustion gas is heated by the direct contact with the combustion gas. It is quickly dissolved and mixed into the raw water, and the pH becomes acidic water suitable for lotions, etc., of 4.5 to 6.
．． Cosmetic liquids that are allowed to cool and precipitate in an air-cooling sedimentation tank may be because it is possible to continuously produce cosmetic liquids within the range of 5 in an appropriate manner and in large quantities without using any chemicals or additives. The liquid is circulated back to the water sprinkler via the circulating liquid supply pipe and pump, and is repeatedly brought into direct contact with the combustion gas to increase its acidity and reduce P.
The value of H can be adjusted to a desired value.

In addition, the liquid collection chamber is connected to the liquid storage tank via the air-cooled sedimentation tank and the filter, so even if the obtained cosmetic liquid reaches a high temperature due to direct contact with the combustion gas, the liquid collection chamber is connected to the liquid storage tank through the air-cooled sedimentation tank and the filter. Impurities are precipitated while it is left to cool in the tank, and the supernatant liquid is supplied to a filter for further purification.Finally, the clean cosmetic liquid can be stored in a storage tank, so it can of course be used as a lotion. It can be used as a basic cosmetic liquid in a wide range of fields, such as a cleaning liquid or a basic moisture for cosmetics.
