Surfactants use fatty acids or higher alcohols for lipophilic groups and polyhydric alcohols or high molecular compounds for hydrophilic groups, and have extremely high stability in cosmetics and ointments. However, many of them are synthetic products using petroleum products as raw materials, and have a high degree of penetration into the skin. However, at present, there is no known substance exhibiting an excellent surfactant activity, and at present, nonionic surfactants having relatively high safety are selected and used.

When the concentration of dissolved silica exceeds 100 ppm, polymerization is accelerated. It is said that. It is known that it exists in the form of a hydrosol in water and has a special behavior and ionic reaction different from other ions. That is, monomeric silica is extremely unstable and easily condensed (ion-reacted). Depending on the concentration, temperature, and pH, monomer silica is sequentially polymerized (condensed) and polymerized into dimers and trimers. Then, polymer silica (polysilica) is formed by the siloxane bond, and eventually gels.

る。In this process, oils, proteins, organic chemicals, natural organic substances and the like are adsorbed to form micelles. That is,
Monomer silica has both + and-poles in water, and is attracted and bound to a substance having both poles, such as an organic substance, to be converted into micelles and stabilized. In addition, ions are taken in as a compound, and impurities such as bacteria are adsorbed. In the present invention, purified water for cosmetics is obtained by completely coagulating and separating the inclusions in water by utilizing this phenomenon. The micelle-forming ability of the monomer silica is extremely strong, and even a nonylphenol-based synthetic surfactant exhibiting a strong surface-active action is formed into a micelle. In addition, the oil component of cosmetics is converted into micelles to stabilize. Furthermore, when an excess monomer silica is added and polymerized to form a sol-gel, a micelle-containing colloidal substance having high water retention is obtained.
When the concentration of oily components is low, such as in the lotion of cosmetics, a low concentration monomer silica solution is used, but the formed micelles turn into a sol or dissolved silica (about several ppm).
As stable in water systems. In the case of cosmetics containing a large proportion of oily components such as emulsions and creams, gelation is performed using a monomer silica solution having a high concentration. The hydrous and gelled silica has extremely high stability and does not dry easily and shows excellent water retention. Moreover, unlike synthetic surfactants conventionally used, silica is a harmless substance, and its use of micelle forming ability in a slightly acidic region is extremely significant.

等から得たものでもよい。[0010] As described above, it is difficult to obtain a monomer silica solution, particularly a monomer silica solution having a high concentration, although it is a monomer silica having a specific aggregation ability. This is because silica does not dissolve in strong acids but partially dissolves in strong alkalis.
This is because gelation occurs quickly when the pH drops. The present inventor has succeeded in obtaining a highly concentrated acid-soluble silica-alumina-calcium solution very easily by dissolving slag in dilute sulfuric acid. Slag is SiO 2 , Al 2 O 3 , Ca
The main and sub components are composed of O, MgO, etc.
Since Al and Ca are bonded via O, they are easily dissolved in dilute sulfuric acid or dilute hydrochloric acid. Of course, the monomer silica of the present invention is not limited to those derived from slag,

For example, 4.2 g of slag is dissolved in 100 ml of 1N sulfuric acid at room temperature, and the undissolved residue and the resulting precipitate are filtered off to obtain a monomer silica concentration of about 1.2% (1%).

This aqueous solution is stable without coagulation for several tens of hours or more when the pH is in the range of 2.5 to 3.5, and is particularly stable for several tens of days in the range of pH 3.1 to 3.2. Monomer silica concentration is 5,000 ppm or less and pH 2.5 to 3.
5. If the pH is in the range of 3.1 to 3.2, more preferably, it is stable for half a year. In addition, by devising the dissolution method, etc.
It can be easily obtained up to a monomer silica concentration of about 2% (20,000 ppm).

First of all, in the case of lotion, most of it is ethanol and purified water to which glycerin, a small amount of fragrance and other components are added. Then, as the purified water, a separated water obtained by coagulating and separating a contaminant (impurity) in water with monomer silica is used. To coagulate and separate contaminants in water,
First, water is acidified to a pH of 4.2 or less, more preferably 3.0 to 3.2, and then water containing monomeric silica is added, followed by stirring and mixing to form micelles. Then, neutral to weakly acidic
When pH is adjusted to about 6.0, aggregation appears. This is removed by filtration means. The amount of monomer silica-containing water used in this case is determined by the amount of contaminants present in the water. Residual monomer silica that has not been consumed can be used at a low concentration. This separated water can be obtained very easily and at low cost, and is sterile and resistant to long-term storage. Some lotions use a surfactant for stabilizing oily components. In this case, a small amount of an aqueous monomer silica solution may be added in place of the surfactant to form micelles of the oily component and stabilize the emulsion.

ではない。In the case of emulsions and creams, the separated water may be used as purified water. However, these are rich in glycerin, glycols, squalene, stearic acid, beeswax, lanolin and other oily components. Therefore, when these oily components are directly added to the aqueous solution of monomer silica and mixed by dissolution, micelles are formed and further sol-gelation is carried out to form a hydrocolloid, which is stable. The hydrogelated silica is extremely stable, does not dry easily, and has high water retention. When ultrasonic mixing is performed, very fine particles having excellent stability can be obtained. Also in this case, the initial liquid is made acidic (preferably pH
3.0 ± 0.2), then neutral to weakly acidic (pH 5.5)
To 6.5), but it is not limited to this step.

If the amount of monomer silica is 0.5 to 1 g per 0 g, micelles can be formed almost completely. If the oil component in the cream is up to about 50%, the use of an aqueous solution having a high monomer silica content can stabilize the emulsion in the same manner as the emulsion.

As described above, even if ordinary water or hot water is used in an ultrasonic face wash, there is almost no effect. In contrast, when the monomer silica aqueous solution of the present invention is combined with an ultrasonic facial cleanser, an extremely good facial cleansing effect can be obtained. However, the facial cleansing solution of the present invention has a sufficient effect even when used for facial cleansing without using an ultrasonic facial cleanser. It is sufficient that the silica concentration of the aqueous monomer silica solution used is 100 to 500 ppm. It is efficient if a monomer silica aqueous solution having a high concentration of several thousand ppm or more is prepared and diluted with tap water or the like before use. However, the monomer silica aqueous solution has a pH of 3.1 to 3.1 for storage.
Because of 3.2, the pH of the diluted face wash may be too low. In this case, the alkali is added and the pH is adjusted.
Is preferably set to 6 to 7.

Example 1 (Preliminary experiment) (1-1) Sulfuric acid was added to 1 liter of water containing 300 mg (300 ppm) of rapeseed oil to adjust the pH to 3.0, and then 30 mg of monomeric silica was added and mixed. At this stage, micelles are formed. Next, caustic soda was added so as to have a pH of 6.5 to express aggregation, and this aggregate was separated. Although 1 mg or less of oil remained in the separated water, most of the oil was removed by micelle formation. (1-2) 5 g (50,000 ppm) of rapeseed oil and 5 g (50,000 ppm) of protein (nonfat dry milk) are put into 1 liter of water, and the pH is adjusted.
Adjust to 3.0. To this, an equivalent amount of monomer silica (500 mg) was added and mixed to convert the oil and protein into micelles.
Aggregation was developed at H5.5. In the separated water, 130 mg of oil and protein remained, but this was due to re-elution of contamination such as adhesion to a container, and the others were formed into micelles and removed. (1-3) 1 ml of vegetable oil was added to 100 ml of an aqueous monomer silica solution having a monomer silica concentration of 2,000 ppm, and the mixture was ultrasonically dissolved to form micelles and completely emulsified and stabilized.

Because monomeric silica acts as a micelle-forming agent, the use of harmful synthetic surfactants can be reduced or eliminated, providing significant good news for skin health. Sol-gel silica, in which monomer silica has been polymerized, exhibits an excellent water-retaining effect, and can keep the skin moist for a long time. Separated water obtained by coagulating and separating an in-water mixture using monomer silica contains no harmful bacteria such as spoilage bacteria, no harmful heavy metals, and the like, and contains trace amounts of effective minerals such as silicon, magnesium, and calcium. Moreover, it can be obtained at a low cost with a simple operation. Therefore, it is ideal as purified water for cosmetics. An aqueous monomer silica solution or a water obtained by diluting the same becomes an ideal face wash when combined with an ultrasonic face wash.
