JP2000233102A - Process for extracting constituent from shotoku-seki, and cosmetic to which the extract is added - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain an extracted liquid which is free from generation of discoloration and putrid smell and obtain further cosmetics to which the extract is added by extracting constituents at ordinary temperature from shotoku-seki a name of stone ground in powder by using ethyl alcohol aqueous solution of which a volume or volume % is specified. SOLUTION: A raw ore of sampled shotoku-seki is ground to a powdery state with a grinder. After adding 25-35 vol./vol.% of ethyl alcohol aqueous solution to this powder, it is left to stand at an ordinary temperature over one week to one month while it is stirring in a hermetically sealed container, and constituents of metal ions or the like contained in shotoku-seki are leached out in the ethyl alcohol aqueous solution. Then, the powder in the container is filtered, or supernatant in an upper part of the container is sampled, and an extract is obtained. The extract is added at a ratio of, for example, 0.1-5 wt./wt.% to cosmetics of cream, soap, toilet water or the like. Then, by medical effects of mineral ions or organic matter which are contained in the extract, metabolism function of the body is accelerated, or a hair root cell is activated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for extracting components from Shotokuishi and cosmetics to which the extract is added.

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open No. 48-92514 discloses that after crushing Shotoku stone, it is immersed in clear water for about one month, and the solution filtered with a filter is dried at 100 ° C. under normal pressure for about 4 hours.
A method is disclosed in which an ionic leachate is obtained by boiling for 0 minutes and standing for several hours.

[0003]

However, the extract obtained by the method of JP-A-48-92514 has a pale yellow-brown color, which changes color to dark brown and rot odor upon irradiation with sunlight. Therefore, it is not preferable to add such an extract to cosmetics even in a very small amount. An object of the present invention is to provide a method for obtaining an extract which does not cause such discoloration and generation of putrid odor, and a cosmetic product to which the extract is added.

[0004]

In order to achieve the above object, the present invention provides a method for extracting components from Shengtoku stone, comprising the steps of: preparing 25-35 vol / vol% ethyl alcohol from powdered grindstone; The components are extracted at room temperature using an aqueous solution.

In addition, the cosmetics to which the extract from Santoku stone of the present invention is added are obtained by extracting components at room temperature from 25 to 35% by volume / volume of ethyl alcohol aqueous solution from the powdered Santoku stone. The liquid is added to the cosmetic.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A rough shot of a Shotoku stone is collected and pulverized with a crusher. To this powder, an aqueous solution of ethyl alcohol of 25 to 35% by volume / volume is added, and the mixture is left at room temperature for one week to one month with occasional stirring in a closed container. Leach in ethyl alcohol aqueous solution. Extraction is obtained by filtering the powder in the container or collecting the supernatant at the top of the container. This extract contains inorganic ions such as sodium ion, calcium ion, iron ion, aluminum ion and magnesium ion, and ethyl alcohol-soluble organic matter.

This extract is a pale yellow transparent liquid,
When this extract is added to cosmetics such as creams, soaps, lotions, hair tonics, etc. at a ratio of 0.1 to 5% by weight / weight, the applied skin is applied due to the medicinal effects of inorganic ions and organic substances contained in the extract. Promote the metabolic function of
Stimulate and activate hair root cells.

EXAMPLE A rough stone of Shotoku stone is made into a powder of 100 mesh or less by a crusher and sufficiently mixed. 100 g thereof was placed in a container and prepared with 95 vol./vol.% Of ethyl alcohol and purified water obtained by a combination treatment of distillation and ion exchange.
1000 cc of a 0 vol / vol% aqueous solution of ethyl alcohol was added as a solvent, and the vessel was sealed. The vessel was stirred once a day for 20 minutes and left at room temperature for 7 days. The supernatant is collected and used as an extract. This extract is a pale yellow transparent liquid,
There was no discoloration or sedimentation after irradiation with sunlight for a week, and no rotten odor was observed. The magnesium ion concentration in the extract, which was measured as a measure of the amount of leached inorganic ions, was 0.3 mg / kg.

As Comparative Example 1, the solvent of the above example was
Extraction was performed under the same conditions as in the example, except that the aqueous solution was changed to a 0 vol / vol% ethyl alcohol aqueous solution. This extract is 2
After a week of sunlight irradiation, the color changed from slightly pale yellow to pale yellow, and a slight odor of putrefaction was observed.

As Comparative Example 2, the solvent of the above example was
Extraction was performed under the same conditions as in the example, except that the aqueous solution was changed to a 0 vol / vol% ethyl alcohol aqueous solution. The magnesium ion concentration in this extract was 0.05 mg / kg, which was extremely lower than that in the above-mentioned Example.

From the above Examples, Comparative Examples 1 and 2, when the concentration of ethyl alcohol in the ethyl alcohol aqueous solution is less than 25% by volume / volume, discoloration of the extract and generation of putrid odor occur. Ethyl alcohol concentration of 3
When the content exceeds 5% by volume / volume, it can be seen that the amount of leached inorganic ions is significantly reduced. Therefore, in order to extract components from Shotokuishi and add the extract to cosmetics, 25
Most preferably, the components are extracted using aqueous ethyl alcohol solutions of up to 35% vol / vol.

In the above Examples and Comparative Examples, in order to measure the extraction efficiency from the concentration of inorganic ions in the extract, ethyl alcohol was diluted using purified water subjected to a combination treatment of distillation and ion exchange. The present invention can be practiced by using water suitable for drinking instead of purified water.

[0013]

According to the present invention, as described above, it is possible to efficiently obtain an extract having a high component concentration without discoloration or spoilage odor due to irradiation with sunlight. In addition, even if the obtained extract is added to cosmetics, the medicinal effect of the extract due to inorganic ions and organic substances can be maximized without significantly lowering the quality of the cosmetics due to discoloration or odor. .
