Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a synthetic mica composite, and more particularly to a synthetic mica composite in which a specific cation is intercalated between layers of a swellable synthetic mica.

[0002]

2. Description of the Related Art Although the use of synthetic mica for cosmetics has been studied in the past, natural mica is still mostly used and synthetic mica is rarely used. Natural mica is often used because it has excellent transparency in the finished state of makeup and spreadability at the time of application, but if it is added in a large amount in order to improve the smoothness to the applied body, press moldability becomes poor. I will end up.

Further, synthetic mica generally has a temperature of 1300 ° C.
It is manufactured by a method of crystallization after melting for a long time at the above high temperature, and pulverization is necessary for pulverization. For this reason, the cost is very high, and it is not possible to control it into a uniform shape. When blended in cosmetics, the spread is poor and the whiteness of the applied cosmetics is satisfactory. Was not. On the other hand, as sunscreen cosmetics, it is known to blend titanium oxide, zinc oxide, etc., but although mixing them alone has a sunscreen effect, dispersibility in a cosmetic base and usability are poor, which is preferable. It wasn't something.

Japanese Unexamined Patent Publication (Kokai) No. 58-19379 discloses an ultraviolet absorber containing, as a main component, synthetic mica containing nickel, cobalt, manganese, titanium, vanadium and barium, and in Japanese Unexamined Patent Publication (Kokai) No. 3-33179. , Te, B

An ultraviolet absorber containing a synthetic mica as a main component containing V, Mn, Ni, Co, Zn and Ti is described. These UV absorbers are produced by the melting method, and are crushed into fine particles, but since they are granular in shape, even if these UV absorbers are blended with cosmetics, the spreadability will be increased. It was bad and was not always satisfactory in terms of finish and usability.

Further, Japanese Patent Laid-Open No. 3-8712 discloses that
It has been disclosed that when a synthetic mica containing Ce between the layers of the synthetic mica is mixed with a cosmetic, an ultraviolet absorbing effect can be obtained. However, in order to make the synthetic mica fine, it is necessary to grind and However, there is a problem in that the finished state and usability are not satisfactory even if it is added to the cosmetics after the treatment.

[0006]

The problem to be solved by the present invention is to provide a synthetic mica composite which is fine and can be easily manufactured. When it is added to cosmetics, the hiding power, the finished state of makeup such as the beauty of the finished film,
It has excellent usability such as spreadability on the skin and peeling off to an applied body such as a sponge. Further, the problem to be solved by the present invention is to provide a fine and easily produced synthetic mica composite having an ultraviolet absorbing effect. When it is mixed with cosmetics, it is possible to exert an excellent ultraviolet absorbing effect and also has excellent transparency in the visible light portion, hiding power, the finished state of makeup such as the beauty of the finished film,
It has excellent usability such as spreadability on the skin and peeling off to an applied body such as a sponge.

[0007]

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION The swelling mica used in the present invention may be any one having a property of swelling in water,
Those synthesized by a melting method or a hydrothermal synthesis method.
Examples include those synthesized by the method described in JP-A-149415. As the swelling mica synthesized by the melting method or the hydrothermal synthesis method, Na-type tetrasilicon mica,
Examples thereof include Li-type tetrasilicon mica, Li-type teniolite, Na-type hectorite, and Li-type hectorite. A swelling synthetic mica obtained by heat-treating a mixture of talc and an alkali silicofluoride or an alkali fluoride is disclosed in Japanese Patent Application Laid-Open No. HEI-2.
It can be synthesized by the method described in JP-A-149415. In this method, sodium silicofluoride and / or lithium silicofluoride (Na ₂ SiF ₆ , L
i ₂ SiF ₆ ) and talc mixture at 700-900 ° C.
Can be manufactured by heat treatment. Specific examples include swellable synthetic mica represented by the following general formula. Formula: α (Na, Li) F · β (aMgF ₂ · bMgO)
γSiO ₂ (wherein α, β, γ, a and b each represent a coefficient, α is 0.1 to 2, β is 2 to 3.5, γ is 3 to 4, and a and b are 0.
To 1 and a + b = 1)

Interlayer ions include Na ⁺ and Li ^+.
If There a large alkali metal ions and Ca ⁺⁺ in is a common atomic weight than Na ^+, such as K ^+, an alkaline earth metal ions such as Mg ^++, Na ^+, including some cations other than Li ⁺ However, the swelling property in water may be maintained, and the interlayer ions are not limited to Na ⁺ and Li ⁺ . Also, not all interlayer ions are exchangeable cations, but exchangeable cations and non-exchangeable cations. The amount of methylene blue adsorbed (a simple method for cation exchange capacity) is different depending on the type of mica and the synthesis method. By 15 to 150 meq / 10
It is about 0 g, and various ions can be ion-exchanged according to the amount of adsorption. The swellable synthetic mica is a member of a phyllosilicate having a sandwich type three-layer structure in which two silica tetrahedral layers sandwich a magnesium octahedral layer, and has a cation exchange ability in water, Furthermore, it is a clay mineral that exhibits the unique property of taking in water between layers and swelling.

It is obtained by ion exchange with one or more ions selected from the group consisting of r and Ti.

As a method for ion exchange of interlayer ions, for example, the concentration of swelling synthetic mica is 0.1 to 10% by weight.
This can be performed by mixing the solution prepared in step 1 and the aqueous solution containing each element ion and then stirring. As the aqueous solution containing each element, a solution obtained by dissolving various salts such as chlorides and sulfates of each element in water may be used. In the case of ion-exchange with two or more kinds of ions, it may be ion-exchanged with a specific element ion and then ion-exchanged with another ion again. Further, when sufficient ion exchange cannot be performed by one-time ion exchange, it is possible to increase the concentration of interlayer ions by using the same ion and repeatedly performing ion exchange.

The amount of the exchangeable cations to be ion-exchanged is 10 to 95 equivalent% of the exchangeable cations, preferably 5
0 to 90 equivalent% is preferable. This is because when the amount of ion exchange is less than 10 equivalent% of the interlayer ions, the synthetic mica complex is not sufficiently precipitated and separation from the solution is difficult.
Further, if the ion exchange is performed in excess of 95 equivalent% of the interlayer ions, the aggregation of the synthetic mica complex becomes too large.

As a method for washing and separating the synthetic mica complex, for example, a method such as a filtration method, a centrifugation method, a gradient method or the like can be used.

The synthetic mica composite obtained by the above method is
The synthetic mica complex does not disperse in water or absorb water, because it is precipitated / produced in the solution by intercalating the elemental ions, and it has excellent durability for makeup. is there.

Further, since the synthetic mica composite of the present invention has an aspect ratio of 15 or more and becomes fine, by incorporating this synthetic mica composite into a cosmetic, a cosmetic excellent in the finished state of makeup is provided. To be done.
