Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning agent, and an object of the present invention is to provide a cleaning agent which has a high effect of smoothing the skin and is excellent in use feeling.

[0002]

2. Description of the Related Art Soap, a type of surfactant used as a detergent, is a metal salt of a higher fatty acid having 8 or more carbon atoms, such as lauric acid, palmitic acid, and stearic acid.
It is produced by saponification of fats and oils or neutralization of fatty acids. This soap has been widely used for skin washing and clothes washing for a long time, and even now when synthetic detergents are widely used, solid soap is still used for washing skin such as hands, face and body. . Recently, liquid detergents such as body shampoos have also been widely used in addition to bar soaps.

[0003] On the other hand, charcoal is a porous material and contains a large amount of minerals such as calcium and potassium, and thus has been widely used in various fields such as cooking, beauty / health, and horticulture. For example, it is used for purifying tap water, and is used as a deodorant and an insect repellent. Also, in order to cook rice deliciously and plumply, charcoal may be added when cooking rice or charcoal may be put into the bath to change the bath water to alkaline and reduce back pain, coldness etc. Is being done.

[0004] As described above, when charcoal is used for cooking, beauty and health, particularly when it is used for purifying tap water, or when charcoal is put into a rice or bath, if the charcoal is used as it is, pulverized coal is used. However, since water and rice may mix with water and rice, and the water and rice may darken, charcoal is usually washed and then sterilized by boiling.

[0005]

The present inventor believes that a large amount of water-soluble carbon minerals are eluted in the cleaning solution remaining after washing the charcoal and the boiling solution remaining after boiling the charcoal. After extensive research on the use of this washing solution and boiling solution, we have found that by including it in soaps and shampoos, the effect of smoothing the skin is higher than that of conventional detergents, and the usability is better. It has been found that the present invention can be used as a cleaning agent, and the present invention has been completed.

[0006]

In other words, the invention according to claim 1 comprises a cleaning liquid remaining after washing by adding water to charcoal and / or a boiling liquid remaining after boiling by adding water to charcoal. The invention according to claim 2 relates to a cleaning agent characterized in that the total content of the cleaning solution and the boiling solution of the charcoal is 0.1%.
The cleaning agent according to claim 1, wherein the cleaning agent is 5 to 7% by weight, wherein the cleaning agent is a soap containing no edetate. Item 13. The cleaning agent according to item 1 or 2.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The cleaning agent according to the present invention includes a cleaning solution remaining after washing by adding water to charcoal (hereinafter, simply referred to as a washing solution) and / or a boiling solution remaining after boiling by adding water to charcoal. (Hereinafter simply referred to as a boiling liquid).

[0008] Specifically, the charcoal washing liquid is water remaining after charcoal and water are put in a container or the like, the charcoal surface is washed using a scourer or the like in the container, and the charcoal is removed. Since this cleaning liquid contains a large amount of pulverized coal, the one filtered with a filter or the like is used as the cleaning liquid for charcoal.

[0009] Further, the boiling water of charcoal is, specifically, water remaining after washing and disinfecting by pouring washed charcoal and fresh water into a container or the like, and removing the charcoal. In addition, it is necessary to use washed charcoal for boiling so as not to mix the differential charcoal in the boiling liquid. May be used. That is, first, a washing solution of charcoal may be obtained, and then a boiling solution may be obtained. However, washing may be performed in running water, and only the boiling solution may be collected and used without obtaining the washing solution.

The amount of water used for boiling the charcoal is not particularly limited, but may be about 0.5 to 1 liter of water per 100 g of charcoal. Also, the boiling time is not particularly limited, and the amount of the finally obtained boiling liquid is 1/3 of the amount of water added first.
It may be boiled until it is concentrated to about 1/5. still,
Calcium eluted from charcoal, during boiling, reacts with carbon dioxide in the air to partially become calcium carbonate, crystallizes and precipitates, but in the present invention, only the supernatant excluding precipitated calcium carbonate crystals is removed. May be contained in the detergent, or the calcium carbonate crystals may be contained in the detergent together with the boiling liquid.

[0011] The type of charcoal used for obtaining the washing solution or boiling solution of charcoal used in the present invention is not particularly limited, and any kind of washing solution or boiling solution of charcoal can be suitably used. That is, the raw wood is baked at 750-1000 ° C.
White coal obtained by carbonizing at 50 to 520 ° C,
Any of black charcoal obtained by baking the raw wood at 400 to 750 ° C. and carbonizing at 250 to 450 ° C. can be preferably used. For example, as white charcoal, Uba megashi (Quercus phillyraeoides) is used as a raw wood and fired at around 1000 ° C. Charcoal made from oaks and oaks belonging to the Fagaceae oak genus (Quercus) such as bincho charcoal,
Charcoal and cedar (Cryp) using bamboo belonging to the Gramineae family
tomeria japonica) and cypress (Chamaecyparis obtus)
a), Japanese red pine (Pinus densiflora), Japanese black pine (Pinus
thunbergii) and other charcoal made from softwood. Black charcoal is Quercus acut
issima) and charcoal (Quercus serrta Thunb) as raw wood.

The cleaning agent according to the present invention can be obtained by incorporating both or both of the cleaning solution and the boiling solution of charcoal obtained by the above method into the cleaning agent.
As is clear from the examples described later, this cleaning agent is excellent in the feeling of use, especially in the effect of smoothing the skin.

[0013] A large amount of minerals such as potassium, calcium and magnesium, particularly water-soluble minerals such as potassium, contained in the charcoal are eluted from the washing solution and the boiling solution of the charcoal. For example, the concentration of potassium in the boiling liquid is 700
750 ppm, which is very high. The present inventor has guessed that by including such a large amount of minerals, the feeling of use of the detergent, particularly the effect of smoothing the skin, may be enhanced. The pH of the washing liquid and the boiling liquid is 8 to 1.
Since it is 0 and is alkaline with little irritation to the body, a detergent using it has no skin irritation and is highly safe. In addition, when the washing solution of charcoal was analyzed,
At 3 ° C., pH 8.5, potassium 120 mg / L, calcium 20 mg / L, magnesium 11 mg / L,
The sulfate ion was 21 mg / L and the silicic acid was 32 mg / L. Further, a liquid obtained by concentrating the washing solution five-fold was also analyzed. As a result, at 23 ° C., the pH was 9.56, potassium was 723 ppm, and calcium carbonate was 216 mg / L.

The total content of the washing solution and the boiling solution of charcoal is not particularly limited, but is preferably 0.5 to 7% by weight. If the content is less than 0.5% by weight, the effect of the cleaning solution and / or the boiling solution is not sufficiently exhibited, while
If the ratio exceeds the above range, the foaming power of the cleaning agent is reduced, and in either case, it is not preferable.

Further, the detergent according to the present invention may contain edetate (EDTA) as a preservative and an antioxidant as long as the effects of the present invention are not impaired. still,
In particular, when the detergent is in the form of bar soap, it is more desirable not to incorporate edetate. This is because, when edetate is blended into bar soap, chelation by edetate occurs and is contained in the washing solution and boiling solution of charcoal.
This is because the effects of minerals such as potassium, calcium, and magnesium may not be suitably exerted. In addition, it is of course possible to add a compound such as a fragrance or a dye, which is compounded in a usual cleaning agent.

The form and properties of the detergent according to the present invention are not particularly limited, and may be solid soaps or powdered soaps, and may be in the form of liquids, creams, or gels, such as body shampoos, facial cleansing cosmetics, and cleansing. It can also be used as a skin cleanser such as an agent or a hair cleanser such as a shampoo. When used in a hair cosmetic, the effect of smoothing the scalp and hair can be enhanced.

The method for incorporating the cleaning liquid and / or the boiling liquid into the cleaning agent is not particularly limited. For example, when the cleaning liquid and / or the boiling liquid are contained in the solid soap, the cleaning liquid and / or the boiling liquid and, if necessary, Then, EDTA may be mixed and cooled and solidified.

[0018]
