Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention can be used as a lotion by simply and easily acidifying a large amount of PH of purified water or purified water, or a cleaning liquid or a cosmetic product. The present invention relates to a method and an apparatus for producing a cosmetic liquid that can be used as a basic cosmetic liquid in a wide range of fields such as basic water.

[Prior Art] Conventionally used cosmetics or cleaning cosmetics that are generally used are those that have been adjusted to be acidic in advance. And the surface of human skin is acidic (PH4.5
~ 6.5), it means that organic acids (eg citric acid, tartaric acid, lactic acid, etc.) are needed to bring the pH closer to its acidic level.
Is added to the lotion to be acidified, and astringent action is given to the skin surface by the acid content, which gives a pleasant stimulus to the skin, a method for producing a lotion or cosmetic suitable for oily skin, and the above lotion or cosmetic, A manufacturing method in which natural plant fluid, ethanol, or the like is added to give a refreshing feeling to the skin is well known without exemplifying it before the present application.

[Problems to be solved by the invention] By the way, in the conventional method for producing this kind of cosmetic liquid, in order to bring the acidity of the cosmetic liquid to the pH of the skin as close as possible, an organic acid or other additive is mixed in the cosmetic liquid. However, when such an organic acid or other additive is mixed, when the additive contains a water-insoluble additive, a water-insoluble component for dispersing in water is added. Since it is necessary to further mix the additives and the like, the number of kinds of the additives is further increased, and as a result, there is a problem that the adverse side effects caused by the additives are increased.

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, and thus, a cosmetic solution suitable for the skin can be easily prepared. It is an object of the present invention to provide a method for producing a cosmetic liquid and an apparatus therefor that can be produced.

[Means for Solving the Problems] In order to achieve the above object, in the method for producing a cosmetic liquid of the present invention, the raw water flowing from the upper portion to the lower portion is provided with combustion gas that is flamed from the lower portion to the upper portion. Make direct contact,
Carbon dioxide in combustion gas is dissolved and mixed in raw water, and PH is 4.
This is an acidic cosmetic liquid having a value within the range of 5 to 6.5.

Then, in the above method, if the liquid in which carbon dioxide gas in the combustion gas is dissolved and mixed in the raw water is repeatedly brought into direct contact with the combustion gas to adjust the PH, a pH cosmetic liquid suitable for acidity of the skin is rapidly produced. can do.

Further, in the method for producing a cosmetic liquid of the present invention, in the upper stage of the main body, a heat exchange chamber provided with a water sprinkler and a heat exchange layer,
The combustion chamber facing the combustion port of the burner is arranged in the middle stage, and the liquid collection chamber is arranged three-dimensionally in the lower stage.

Further, if the liquid collecting chamber arranged in the lower stage of the main body is connected to a liquid storage tank via a freezing precipitation layer and a filter, the supernatant liquid from which impurities are precipitated and separated can be stored and stored in a storage tank. .

In addition, the cold settling layer and the sprinkler in the main body are connected via a circulating liquid supply pipe equipped with a pump, and the treated liquid is brought into direct contact with the combustion gas that repeatedly burns, facilitating PH adjustment. The acidity can be made proper by going to.

[Operation] Now, raw water (for example, tap water or spring water) is sprayed evenly from the sprinkler onto the heat exchange layer provided in the heat exchange chamber, and at the same time, the burner is operated to burn the combustion gas. Blow it out into the combustion chamber.

Then, the raw water flows evenly in the heat exchange layer while twisting and bending, and then falls through the combustion chamber into the lower collecting chamber. On the other hand, the combustion gas flames up in the heat exchange layer above the combustion chamber evenly in the direction opposite to the flow direction of the raw water, and is finally exhausted to the outside of the main body through the exhaust port.

Therefore, the raw water that flows downward from above and the combustion gas that flames upward from below should come into direct contact with each other many times in the downstream and flame-raising processes, and it may become hot water. Carbon dioxide (around 13%)
~ 14%) is dissolved and mixed in raw water.

As described above, when a large amount of free carbon dioxide gas is dissolved and mixed into raw water, the raw water naturally becomes a cosmetic liquid that has been treated with an acidity within the pH range of 4.5 to 6.5, and changes to a liquid with a water quality suitable for lotion. It is then supplied from the main body to the cold precipitation layer through the collection chamber, where impurities are once precipitated and separated, and then the supernatant liquid is supplied to a filter to be filtered and finally the cosmetic liquid which has been cleaned up. Was stored in a storage tank and taken out as needed.

Therefore, the cosmetic liquid obtained through the above steps,
Not only is it used as a lotion, but it is also effectively used as a basic moisture for other cosmetics. Moreover, when it is desired to adjust the pH of the cosmetic liquid obtained by the above means, it can be easily achieved by adjusting the carbon dioxide concentration in the combustion gas of the burner. The stored cosmetic liquid is repeatedly supplied to the sprinkler in the main body through the circulation pump and the circulation liquid supply pipe to sprinkle water, thereby making direct contact with the burning combustion gas repeatedly and dissolving the carbon dioxide gas in the gas. It can be mixed in and the acidity can be increased to the required level.

In addition, raw water is burnt in the downstream process (approximately 13
Since it is in direct contact with (00 ° C), ordinary bacteria, Escherichia coli, etc. are sterilized and become sterile. Therefore, it is not necessary to separately add sterilizer such as ethanol.

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

[Advantages of the Invention] Since the present invention includes the method and the apparatus as described above, the following advantages are achieved.

Since the combustion gas burning from the lower part to the upper part was brought into direct contact with the raw water flowing from the upper part to the lower part, the carbon dioxide gas contained in the combustion gas in a large amount was heated by the direct contact action with the combustion gas. It quickly dissolves and mixes in the raw water that has become acidic, and becomes an acidic water quality suitable for lotion, etc.A cosmetic liquid whose PH is in the range of 4.5 to 6.5 is suitable and large in volume without using any chemicals or additives. Permanently, the cosmetic liquid that has been left to cool and settle in the cooling settling tank is circulated back to the sprinkler via the circulating liquid supply pipe and pump, and is repeatedly in direct contact with the combustion gas. Thus, the acidity can be increased to adjust the PH value to a desired value.

Furthermore, since the liquid collection chamber is connected to the liquid storage tank via the cold settling tank and the filter, even if the obtained cosmetic liquid has a high temperature due to the direct contact with combustion gas, the cold settling will occur. Impurities are precipitated while being left to cool in the tank, and the supernatant liquid is supplied to a filter for further purification. Finally, a clean cosmetic liquid can be stored in a liquid storage tank, so of course it can be used as a lotion as it is. Therefore, it can be used as a basic cosmetic liquid in a wide range of fields such as a cleaning liquid or basic water for cosmetics.
