Description

Technical Field [0001] The present invention relates to a method for producing a mineral extract for cosmetic raw materials using sandstone and a mineral extract for cosmetic raw materials,

The present invention relates to a method for producing a mineral extract for cosmetic raw materials using sandstone and a mineral extract prepared thereby, and more particularly, to a method for effectively dissolving minerals from sandstone, To a mineral extract having a high colloidal state.

Minerals are an important substance that is essential for the formation of cells, body fluids, enzymes, muscles and skeletons of the human body. When the minerals in the body are lacking or the balance is broken, the biochemical functions of various organs in the human body are degraded and the immune function is lowered. It is easily exposed. In addition, minerals are important substances in skin cosmetics, and they are important for preventing aging of skin, promoting moisture retention of skin cells, preventing moisture loss of skin tissue, and maintaining skin flexibility, elasticity and the like.

Therefore, cosmetics containing minerals are introduced. Most of them use artificially manufactured mineral composition, which causes adverse effects on the skin and does not have various kinds of minerals.

Meanwhile, methods for extracting minerals from natural minerals have been proposed, and natural minerals extracted from natural minerals are also used as cosmetics elder. However, the conventional method for extracting minerals is unsuitable for use as a raw material for cosmetics because of the possibility of remaining strong acid in minerals extracted by the method using sulfuric acid and the method using supercritical system, There is a need for an expensive production equipment and a complicated manufacturing process

On the other hand, sandstone is hardened rock formed by accumulation of minerals dissolved in groundwater passing through sandy sedimentary rock sand made by piled up particles by transportation. It consists mainly of quartz, feldspar, and rock fragments (rock fragments). It contains a matrix that fills the gap between minerals and particles. It contains various types of main minerals such as quartz and feldspar, Sandstone is a considerably better source of minerals than other rocks.

Hereinafter, the present invention will be described in more detail.

The present invention relates to a method for extracting minerals from sandstone, and comprises the following steps.

1) Process of crushing sandstone

Crush the prepared sandstone. The lower the grain size of sandstone, that is, the higher the degree of crushing of sandstone, the higher the dissolution efficiency of minerals in the process described later. Therefore, it is preferable to finely crush sandstone in terms of the elution efficiency of minerals. However, as the degree of crushing of sandstone increases, the cost is increased. Therefore, it is desirable to control the crushing degree of sandstone considering this aspect. Preferably, the sandstone is pulverized to have an average particle size of about 4000 to 5,000 mesh.

2) After adding purified water and ethanol to the crushed sandstone and stirring it well, EDTA, Etidronic acid, and Phosphonic acid were added, and the mixture was stirred for at least 4 to 6 hours Allow to stir for about an hour.

In this process, the minerals contained in the sandstone are eluted with purified water and ethanol, etronic acid and phosphonic acid. Among the eluted minerals, the metal ion forms a stable water-soluble chelate compound with editi. In addition, it forms a stable water-soluble chelate compound with the metal ion eluted from the sandstone because it acts as an etronic and a phosphonate chelating agent. As such, the metal ions eluted from the sandstone are kept soluble and not precipitated as they form a water-soluble chelate compound.

In the present invention, ethanol, ethidonic acid, and phosphonic acid are used in combination with purified water because the use of purified water alone for dissolving minerals is limited. In addition, since EDTA, Etidronic acid, and Phosphonic acid have high affinity for metal ions, they have hydrophilic molecules that are excellent in binding ability to metal ions and are not toxic to humans It is preferable to use it in the present invention.

As described above, although the elution degree of the mineral is affected by the grain size of the sandstone, the amount of the additives used in the process and the stirring time are also influenced. Since the dissolution degree of the mineral is proportional to the amount of the additives used and the stirring time, It is necessary to increase the amount of additives used and stir for a long time.

However, even if the use amount of the additives is increased, the elution efficiency is not increased at a certain level or higher. In general, when the chelating agents are applied to the skin in excess, skin irritation is induced. Therefore, In addition, since the production cost and productivity must be taken into account, it is necessary to adjust the dissolution degree of the mineral to an appropriate level. In addition, when the generated chelate compound particles are excessively large, the chelate compound is filtered during the filtering process described below, and the mineral content of the extract is lowered. Therefore, the particle size of the generated chelate compound should be considered. EDTA), etidronic acid, and phosphonic acid are used in a relatively large amount, particles of a chelate compound are formed unnecessarily large.

Considering these various factors, it is preferable to control the amount of the chemicals and the agitation time so that the elution degree of the mineral is about 50 to 85%. For this purpose, in this process, 200-300 parts by weight of purified water is added 20 to 30 parts by weight of ethanol, 10 to 15 parts by weight of eddies, 20 to 30 parts by weight of ethidonic acid and 10 to 15 parts by weight of phosphonic acid are added to 100 parts by weight of purified water. Of course, it is natural that the amount of the additives to be used is adjusted within the above range according to the mineral content of the mineral eluate required by the user.

3) The agitated product is allowed to stand for at least 4 to 6 hours for several hours. In this settling process, the agitated product is separated into a solid component having a high specific gravity and a liquid component containing eluted minerals. As the solid with a large specific gravity sinks downward, the liquid component is separated upward.

4) The solid content is removed from the stirred product, and the liquid component is taken, and then the liquid component is filtered with a microfilter of about 0.2 탆 to obtain a mineral extract solution.

The method of extracting minerals according to the present invention as described above has high efficiency of extracting minerals contained in sandstone, and in particular, the eluted minerals are not precipitated because they form stable water-soluble chelate compounds. Therefore, even if a long time passes, the colloid state having high colloidality is maintained.

The mineral extract prepared according to the present invention is used as a cosmetic raw material and is very advantageous for skin cosmetic because it contains various kinds of minerals. Cosmetic products of any formulation conventionally manufactured in the art can be prepared using such a mineral extract, and they may be supplied by adding an additive such as an emulsifying agent or thickening agent according to the formulation of the cosmetic product.

It can be seen from these examples that the mineral extract obtained according to this example contains various minerals. In particular, with respect to each of the minerals, a high elution rate of not less than 50% . The mineral content of the minerals extract is 69.33%, and the total elution of minerals is 81.31%.

For reference, the contents of sodium and phosphorus in mineral extracts are higher than those contained in sandstones because the disodium used for minerals extraction was provided with sodium and phosphorus in minerals extract by dithia and etidronic acid and phosphonic acid Respectively.
