The mica-titanium-based 1-layer compound blended into the cosmetics of the present invention has excellent pearl luster, safety, water resistance, alkali resistance, solvent resistance, and heat resistance, as well as color separation and odor change in the system. It is a colored mica titanium-based pigment that has pigment characteristics that do not cause oxidation.

Conventional mica titanium pigments are included in the Cosmetic Raw Materials Standards Supplement ■Note 6
As described on pages 54 to 57 of the edition (Published in 1981, Yakuji Nippo), it has a pearlescent luster and various interference colors by forming a titanium dioxide layer on the surface of fine flaky mica, and the manufacturing method is There is also a vacuum deposition process, but as shown in DuPont's patent (Japanese Patent Publication No. 43-25644), an aqueous solution of an inorganic acid salt of titanium (for example, titanyl sulfate) is hydrolyzed in the presence of mica, and hydrated dioxide is formed on the mica surface. A common method is to precipitate titanium and then heat it. The mica used is generally muscovite mica.
mica), but depending on the case, it is also possible to use biotite or the like. In addition, mica is used after it has been roughly crushed in water and the particle size is made uniform using a sieve. The produced mica titanium pigment exhibits various interference colors depending on the thickness of the titanium dioxide coating layer on the mica particle surface. The interference color is usually silvery when the amount of titanium dioxide is ~25% by weight of the product, but golden when the amount of titanium dioxide is ~40%, 40-50% by weight of the product.
In the direction of increase of titanium dioxide layer in the range of %, red, blue,
The color changes to green, and at 50-60%, a higher order interference color is obtained. Table 1 shows the relationship between interference color and the thickness of the titanium dioxide layer on the surface of the mica particles.

Conventionally, in order to produce a variety of external colors, colored pigments such as iron oxide, navy blue, chromium oxide, carbon black, and carmine were added to the produced mica titanium pigments. The safety, light resistance, acid resistance, alkali resistance, solvent resistance, heat resistance, etc. of these colored mica titanium pigments are largely due to the properties of the colored pigments added. The pigment turns brown in an alkaline solution,
A red mica-titanium-based forward tangent containing carmine deteriorates to brown when exposed to light. On the other hand, carcinogenic substances such as 3, 4 and benzpyrene, which can be mixed into carbon plastics, such as black mica titanium pigments with added carbon plastics and green mica titanium pigments with added chromium oxide, etc. There are many safety concerns, such as the toxicity of hexavalent chromium and the oral toxicity of hexavalent chromium. Furthermore, since the above-mentioned colored mica titanium pigments contain colored pigments, when added to cosmetics, etc., they have drawbacks such as color separation in the system and odor changes due to the activity of the colored pigments. I also have it.

In view of the above circumstances, the present inventors have conducted intensive research and have found that by coating the surface of mica particles with titanium dioxide and lower titanium oxide, or with lower titanium oxide, it is possible to replace conventional mica titanium-based pigments or colored pigments. It has a color tone that is equal to or more vivid than colored mica titanium pigments with added pigments, has excellent pearl luster, and has excellent safety, light resistance, acid resistance, alkali resistance, solvent resistance, and heat resistance. They discovered that a colored mica titanium pigment can be obtained, and further discovered that when this pigment is blended into cosmetics, it disperses well and does not cause color separation or odor. Based on this knowledge, The present invention has now been completed.

The present invention provides a cosmetic containing a colored mica titanium pigment whose mica surface is coated with titanium dioxide, lower titanium oxide, or lower titanium oxide.

Generally, commercially available muscovite clouds (musco
Among these pigments, when the colored mica titanium pigment of the present invention is made from particles having a small particle size and a particle shape as flat as possible, more beautiful color tone and pearlescent luster are likely to be exhibited.

The colored mica titanium pigment used in the present invention is a pigment in which the surface of mica particles is coated with titanium dioxide, lower titanium oxide, or lower titanium oxide, and various methods can be used to produce this pigment. can be taken. For example, commercially available mica titanium pigments are reduced at an altitude of 5000°C to 1000°C, preferably 700°C to 900°C, with one or more gases having reducing power such as hydrogen gas and ammonia gas, or by reducing them. A method in which titanium dioxide is mixed with a commercially available mica titanium pigment, and the mixture is heated and reduced by the above method. or by mixing metallic titanium with a commercially available mica titanium pigment and applying the mixture under vacuum for 50 minutes.
00°C to 100°C, preferably 700°C to 900°
Examples of methods include heating reduction with C. Furthermore, DuPont's patent (Japanese Patent Publication No. 43-25644)
An aqueous solution of an inorganic acid salt of titanium (e.g., titanyl sulfate), such as that found in
Hydrous titanium dioxide is precipitated on the surface of mica particles, and heated at 500°C to 1000°C, preferably 7oO'C to 9
With one or more gases having reducing power such as hydrogen gas and ammonia gas at a temperature of 00°C, or by mixing these gases with reducing power and inert gas such as helium gas, argon gas, nitrogen gas, etc. The particles may be heated and reduced with a gas, or hydrated titanium dioxide may be precipitated on the surface of the mica particles and then heated to produce mica titanium, which may be reduced in the same manner as the commercially available mica titanium pigments. In addition, the method of reduction is not limited to the method using a reducing gas such as hydrogen gas or ammonia gas as described above, but also a method of reducing mica titanium using a reducing flame such as hydrogen, a method of reducing mica titanium using a reducing flame such as hydrogen, a method of reducing mica titanium using a reducing flame such as hydrogen, etc. It is also possible to suspend the titanium tetrachloride solution and oxidize and decompose this suspension in a flame of a mixed gas of air and hydrogen. In other words, the colored mica titanium pigment used in the present invention is a colored mica titanium pigment in which the surface of mica particles is coated with titanium dioxide, lower titanium oxide, or lower titanium oxide, and its manufacturing method is known. Any method may be used, and there is no particular restriction.

(Left below) The amount of titanium dioxide and lower titanium oxide or lower titanium oxide that coats mica can be varied within a wide range, and usually titanium dioxide is 0 to 60 parts by weight relative to mica (100 parts by weight). up to an amount of 0.01 to 6 parts of lower titanium oxide
It is possible to coat up to 0 parts by weight. If less than 0.011 parts by weight of lower titanium oxide remains are coated on 100 parts by weight of mica, the resulting titanium mica will not become colored. If the amount exceeds 60 parts by weight, the properties of mica will be extremely poor and particles will agglomerate strongly. This property holds true even when the amount of titanium dioxide exceeds 60 parts by weight relative to 00 parts by weight on mica.

Next, a production example of the colored mica titanium pigment used in the present invention will be specifically described, but the present invention is not limited thereto. Parts in the examples represent parts by weight.

(The following is a blank space) Production Example 1 50 parts of mica was added to 500 parts of ion-exchanged water and thoroughly stirred to uniformly disperse it. The resulting dispersion has a concentration of 0% by weight.
2085 parts of an aqueous titanyl sulfate solution was added thereto, and the mixture was heated and boiled for 6 hours while stirring. After cooling, filter and wash with water 900
90 parts of mica coated with titanium dioxide (mica titanium) were obtained by firing at 'C.

The mica titanium obtained by blowing was subjected to a reduction treatment at 800° C. for 14 hours under an ammonia gas flow at a flow rate of 3 and p/rmn, and after cooling, the powder was recovered. The obtained powder exhibited a bright blue pearlescent appearance and interference color (raw material A).

The surface condition of the particles of the blue mica titanium pigment, which is the original FIA, is as shown in the scanning electron micrograph of FIG. According to this, it is possible to observe that the surfaces of the blue mica titanium pigment particles, which are raw material A, are sufficiently covered with fine particles.

In addition, the X-ray diffraction diagram (au-Kα line) of the blue mica titanium pigment, which is raw material A, is as shown in Figure 2r. According to this, in addition to the diffraction peak of mica, the diffraction angle ( A peak is observed near the Bragg angle 2θ)'25.3°. This is the strongest peak of anatase titanium dioxide (1
01). In addition, a slightly broad peak is observed near 2θ-433°, but this peak corresponds to the strongest peak of titanium monoxide (200), and is the blue color of raw material A obtained in this production example. It can be seen that the mica particle surface of the mica titanium pigment is coated with titanium dioxide and titanium monoxide.

Furthermore, the amounts of titanium dioxide and lower titanium oxide coating the mica particle surface were determined by the method shown below.

(1) A sample before reduction treatment and a sample after reduction treatment were each pulverized using an agate ball mill to render mica amorphous. The sample F-1 was subjected to X-ray diffraction (cu- and α-rays)
The intensity of the diffraction line of titanium dioxide and the diffraction line of lower order titanium oxide is determined by the powder measurement method, and the intensity is compared with the separately determined mixing ratio of mica and titanium dioxide, and the mixing ratio of lower order titanium oxide, which is known by diffraction. The amounts of titanium dioxide and lower titanium oxide were determined by comparing with the intensity calibration curve.

(2) Since all of the lower titanium oxide is converted to titanium dioxide by firing in the atmosphere, the reduced titanium sample was subjected to gravimetric analysis to quantify the amount of lower titanium oxide. That is, about 52 samples were accurately weighed in a 2-Organ magnetic crucible and heat-treated at aOO°C in the atmosphere for 4 hours. After cooling, the weight increase was accurately measured, and the amount of lower titanium oxide was determined from the weight increase.

When the amounts of titanium dioxide and lower titanium oxide in the blue mica titanium pigment, which is raw material A, are determined by the above method,
The blue mica titanium pigment that is raw material A is: Mica 10
0 parts by weight to 64 parts by weight of titanium dioxide and 33.6 parts by weight
This is a blue mica titanium pigment in which the mica surface is coated with parts by weight of low-order titanium oxide.

(Left below) Production Example 2 50 parts of mica was added to 500 parts of ion-exchanged water and thoroughly stirred to uniformly disperse the mixture. A concentrated aqueous solution of titanyl sulfate having a concentration of 31% by weight was added to the resulting dispersion, and the mixture was heated with stirring and boiled for 6 hours. After cooling, it was washed with water and fired at 900'C to obtain 100 parts of mica (mica titanium) whose surface was coated with titanium dioxide.

Next, the obtained titanium mica was subjected to an aoo'C reduction treatment for 14 hours under a mixed gas flow of ammonia gas at a flow rate of 1 l/mm and nitrogen gas at a flow rate of 317 mm, and after cooling, the powder was recovered. The obtained powder exhibited a bright green pearlescent appearance and interference color (Raw material B).

The X-ray diffraction pattern (cu-# line) of the green mica titanium pigment, which is the raw material B, is shown in FIG. According to this, manufacturing example 1
As in the case of Strongest peak of titanium (200)
It is seen that the green mica titanium pigment (raw material B) obtained in this production example has the surface of the mica particles covered with titanium dioxide and titanium monoxide. Further, the amounts of titanium dioxide and low-depletion titanium oxide coated on the surface of the mica particles were determined by the same method as in Production Example 1. the result,
This raw material B7 has a green mica titanium pigment of 7 mica and 10
It was found to be a green mica titanium pigment coated with 0 parts by weight, 38 parts by weight of titanium dioxide, and 462 parts by weight of lower titanium oxide.

Production Example 3 50 parts of mica was added to 500 parts of ion-exchanged water and thoroughly stirred to be uniformly dispersed. The concentration of the resulting dispersion is % by weight.
2085 parts of an aqueous titanyl sulfate solution was added thereto, and the mixture was heated and boiled for 6 hours while stirring. After cooling, p filter and wash with water 10
It was dried at 0°C to obtain 90 parts of titanium mica. The product was heated at a flow rate of 900 mm under an ammonia gas flow of 31 mm/mm.
After reduction treatment and treatment at °C for 13 hours, 90 parts of powder was collected after cooling. The obtained powder had a bright blue pearlescent appearance and interference color (Raw material C). In addition, the amount of titanium dioxide and lower titanium oxide coating the mica particle surface is such that titanium dioxide is the mica particle that forms the core.
The amount of titanium oxide was 4.6 parts by weight, and the amount of lower titanium oxide was <354 parts by weight.

Production Example 4 50 parts of mica was added to 500 parts of ion-exchanged water and thoroughly stirred to be uniformly dispersed. The resulting dispersion has a concentration ■wt%
5 parts of titanyl sulfate aqueous solution 31Z was added thereto, and the mixture was heated while stirring and boiled for 6 hours. After cooling, -wash with water 900
100 parts of mica coated with titanium dioxide (titanium mica) were obtained by firing with:.

Next, 1 or 2 parts of metallic titanium was mixed with 100 parts of the obtained titanium mica, and the mixture was mixed with 100 parts of titanium mica using an oil diffusion pump.
The mixture was heated and reduced in soo'c for 4 hours at a vacuum degree of torr or less. After cooling, 1012 parts of powder were obtained. The obtained powder was a bright blue-green powder with pearlescent appearance and interference color (raw material D). In addition, when the amount of titanium dioxide and lower titanium oxide coating mica in the blue-green mica titanium pigment that is the raw material for this raw material is determined by quantitative methods (1) and (2) described in Production Example 1, it is found that It was found that titanium was 40.5 parts by weight and lower titanium oxide was 95 parts by weight based on 100 parts by weight of mica.

Production Examples 5 to 8 50 parts each of four types of commercially available (manufactured by Marl Inc., USA) mica titanium pearlescent pigments having interference colors were taken, and the type of reducing gas,
Reduction was performed by changing the gas flow rate, reduction temperature, and reduction time.

After cooling, 50 parts of product were obtained.

The color and interference color of the obtained powder were observed with the naked eye, and the color tone was measured by the powder cell method using Color Analyzer 607 (Hitachi) (hue (H), brightness (■) / saturation (C)) )
.

Further, the amounts of titanium dioxide and lower titanium oxide were determined by quantitative methods (1) and (2) described in Production Example 1. The results are shown in Table 2.

Production Examples 9 to 12 50 parts of each of four types of commercially available (manufactured by Marl Inc., USA) mica titanium-based pearlescent pigments having interference colors were taken, the amount of metallic titanium mixed was varied, and the mixture was mixed with 1O- by using a diffusion pump. 3
The vacuum was reduced to below torr and the mixture was heated and reduced at 800°C for 4 hours. After cooling, the color and interference color of the obtained powder were observed with the naked eye, and the color tone was measured by the powder cell method using Color Analyzer 607 (hue (H), brightness (V), intensity (C)).
.

(The following is a blank space) The amounts of titanium dioxide and lower titanium oxide were also determined by quantitative methods (1) and (2) described in Production Example 1. The results are shown in Table 3.

(Hereinafter, blank spaces) The pigment properties of the colored mica titanium pigments, which are the raw materials obtained in Production Examples 1 to 1, were tested. For comparison, the pigment properties of a colored mica titanium-based pearlescent pigment (a conventional mica titanium-based pigment with a colored pigment added) commercially available from Marl Corporation of the United States were tested in the same manner. The commercially available colored mica titanium-based pearlescent pigments that were compared include Raw! 3
A pigment corresponding to the color tone of the colored mica titanium pigment, which is No. 1, is selected. The results are shown in Table 4.

Table 4 Moreover, the composition of the commercially available product is as shown in Table 5.

(Leaving space below) Table 5 Composition of commercially available colored mica titanium pearlescent pigments ``Property, thermal stability, dispersion stability'' The test methods and test results are as follows.

■ Acid stability test 15 g of colored mica titanium pigment, which is the raw material of the present invention, and 15 g of a commercially available colored mica titanium pearlescent pigment are each placed in a 50-liter test tube with a stopper, and 2 cells of N hydrochloric acid aqueous solution are added to the test tube. 30 WL/! After dispersion, the mixture was placed in a test tube stand and allowed to stand, and the color tone after the next hour was observed with the naked eye.

The results are shown in Table 6.

(Left below) As is clear from the results in Table 6, the colored mica titanium pigments that are the raw materials of the present invention were all stable against harsh conditions, but all the commercially available colored mica titanium pearlescent pigments were It is unstable and gradually fades, and after the next hour, commercially available Cloisonelle and Cloisonne de turn white, and Cloisonne Gold, Cloisonne Gold, Cloisonne Blue, and Cloisonne Green become pale and whitish, and their pearlescent luster is extremely reduced. It can thus be seen that the colored mica titanium pigment, which is the raw material of the present invention, has excellent acid stability.

(Leaving space below) Table 6 Acid stability of the colored mica titanium pigment that is the raw material of the present invention Note) ◎ mark: Extremely stable with no change in color tone △ mark: The color gradually fades and the color tone becomes pale and whitish. .

×: Discolors and changes to white ■ Alkaline stability test 15 g of colored mica titanium pigment, which is the raw material of the present invention, and 15 g of a commercially available colored mica titanium pearlescent pigment are each placed in a 50 ml stoppered test tube. After adding ml of 2N loading sodium aqueous solution to the mixture and dispersing it, the mixture was allowed to stand in a test tube stand and the color tone was observed with the naked eye after the next hour.Table 7 shows the results.

Table 7 Alkali placement of colored mica titanium pigment, which is the raw material of the present invention ◎ Extremely stable with no change in two tones △ Mark: The color gradually fades and the tone becomes pale and whitish × Mark: The color fades and changes to white No. 7 As is clear from the results in the table, the colored mica titanium pigment that is the raw material of the present invention is completely stable against alkali, whereas the commercially available colored mica titanium pearlescent pigments are unstable and gradually fade. After 24R, the commercially available Cloisonnere, Do, and Cloisonne Blue changed to white, and the colors of Cloisonne Gold and Cloisonne Green became pale and whitish, and their pearlescent luster was extremely reduced. It can be seen that the colored mica titanium pigment, which is the raw material of the present invention, has excellent alkali stability.

■ Photostability test The colored mica titanium pigment, which is the raw material of the present invention, and the commercially available colored mica titanium pearlescent pigment are each mixed with talc (manufactured by Asada Seifun Co., Ltd.) at a ratio of 37%, and the mixture z5 It was molded into a square aluminum inner plate with a thickness of 3 mm and a side of n mm, and was irradiated with a xenon lamp for a period of time. The color tone after irradiation and the color tone before irradiation were measured using a color analyzer 60'7, and the color difference (ΔE) before and after irradiation was determined from the colorimetric values.

The results are shown in Table 8.

(Margin below) Table 8 Photostability of colored mica titanium pigments, which are the raw materials of the present invention.As is clear from the results in Table 8, the color difference between the colored mica titanium pigments, which are the raw materials of the present invention, before and after irradiation. (△E) is 05
There is almost no difference from the following, and the difference in color tone cannot be distinguished with the naked eye, whereas the commercially available Cloisonne Gold and Cloisonne Gold are 35% each.
It was extremely large at 3.18.0, and the change in color tone was clear even to the naked eye. - Cloisonne green and Cloisonne blue had a large color difference of 6.0 and 5.2, respectively, and it was observed that a color tone change was clearly observed even with the naked eye.

■ Thermal Stability Test Weigh out 3 g of each of the colored mica titanium-based pigment, which is the raw material of the present invention, and the commercially available colored mica titanium-based pearlescent pigment into a 20-person magnetic crucible, and heat the mixture at 200'C and 300°C in the atmosphere.
, 400°C, and 500°C for 2 hours. The powder after treatment was colored with a color analyzer 607, and the color difference (ΔE) from the pigment before treatment was determined. In addition, changes in color tone were observed with the naked eye. The respective results are shown in Table 9.

As is clear from the results in Table 9, the colored mica titanium pigment, which is the raw material of the present invention, is stable up to 400°C with a color difference of 05 or less and almost no change in color tone to the naked eye. 5
When the temperature reaches 00°C, the color changes to yellowish white.

This is because the lower titanium oxide on the surface of the mica particles was oxidized and changed to titanium oxide. That is, it can be seen that the colored mica titanium thread pigment, which is the raw material of the present invention, is stable up to temperatures below 500°C. On the other hand, the color difference of commercially available Cloisonnere, Do, and Cloisonne Blue is 32.3.5 at 2'OO''C, and the color tone change is clearly visible even with the naked eye.At 300'C, the color difference is 36.3.5. 4.262
It grows larger and the color changes from red to yellow-red, and then from blue to reddish-brown. That is, since the color tone of Cloisonnele, Do, and Cloisonne Blue changes at 200° C., it can be seen that they are inferior in thermal stability.

Cloisonné green has a color difference of 7.8 at 400'C, the saturation decreases, and the color changes to dark green. That is, it is stable at temperatures below 400'C, but is unstable at temperatures above that temperature. As for Cloisonné Gold, even at 500'C, the saturation is somewhat inferior, and the color difference is 10 or less, indicating high stability.

Put it in a 50 m13 test tube with a stopper scale and add 0.2% by weight to it. Add 50 ml of phosphoric acid aqueous solution,
Dispersion was carried out for x seconds using a polytron, and this dispersion liquid was further dispersed using ultrasonic waves. After dispersion, the mixture was allowed to stand still in a test tube stand, and the dispersion state was observed with the naked eye immediately after, 5 minutes, 10 minutes, 1 hour, and 1 hour after the standing.

The results were as shown in Table 10.

As is clear from the results in Table 10, the mica titanium pigment, which is the raw material of the present invention, is uniformly dispersed even after standing for 1 hour, whereas the commercially available products Cloisonne Blue, Cloisonelle, and De , Sedimentation was observed after 5 minutes of standing, and the supernatant liquid was blue or red in color. This is simply due to the separation of the mixed navy blue and carmine. Cloizo non-green particles were found to settle after being left to stand, and the supernatant liquid had a darker green color than the green color of the sedimented particles. This is simply due to the separation of the mixed chromium oxide.

Cloisonné Gold was evenly dispersed even after it had settled down for 1 o'clock.

As is clear from the above test results, the colored mica titanium pigment, which is the raw material of the present invention, is stable with no change at all when exposed to alkali or light, and is also stable against heat.
It is stable up to temperatures below 00°C and does not cause any color change. Furthermore, it has excellent dispersibility, does not cause color separation, and has excellent pigment properties.
