Description

[Detailed description of the invention]

The present invention relates to cosmetics containing stable ultramarine blue, and more particularly to cosmetics containing stable new ultramarine blue in which the surface sulfur of ultramarine blue particles is blocked with a zinc compound. Gunjio is an inorganic pigment that usually exhibits a beautiful blue color with a slight reddish tinge.It was originally made from natural lapis lazuli, but now it is exclusively produced artificially. Ultramarine is sodium aluminum silicate containing sulfur, and is generally represented by the following compositional formula. Na(8-9)A
I6Si6024S (2-4) ultramarine is a hydrophilic and oleophobic composition, is stable in air up to about 250 qo, and has ion exchange ability and catalytic ability. Some of the sulfur in ultramarine is in the active radical form, and differences in the radical state and oxidation state of this sulfur cause changes in the color tone of ultramarine, and in addition to the reddish blue mentioned above, it also has a purple tinge. There are some that are yellowish and some that are greenish. Gunjo is
It is used as a blue coloring agent in cosmetics, and has been gaining importance in recent years because its hue is extremely bright and is harmless to humans and animals. However, ultramarine blue has serious deficiencies as a colorant. In other words, ultramarine blue is generally stable to alkalis, but
Extremely sensitive to acids, when ultramarine blue is added to acidic cosmetics, it reacts with the acid and gradually decomposes and fades while generating hydrogen sulfide. Furthermore, even when blended into cosmetics with a relatively high pH, hydrogen sulfide is generated by mechanical shearing force and heat. The hydrogen sulfide thus generated causes problems such as secondary deterioration of container materials such as aluminum, and discoloration and odor of cosmetics. In order to overcome these drawbacks, several proposals have been made to improve the stability of ultramarine. Recent methods include, for example, a method of treating ultramarine blue with sodium silicate and an organic acid to form amorphous silica on the surface (Japanese Patent Application Laid-Open No. 1982-95632), and a method of forming an acid-resistant polymer coating on the surface of ultramarine blue. Method of forming
Publication No. 483). Although these conventional methods improve the acid resistance of ultramarine blue to some extent, they are still not sufficient. In view of the aforementioned circumstances, the inventors of the present invention have conducted extensive research to develop a stable ultramarine blue that has sufficient acid resistance when incorporated into cosmetics. learned that the generation of hydrogen sulfide is effectively suppressed under acidic conditions, and upon further investigation, unexpectedly discovered that treatment with a zinc compound alone had a significant suppressive effect. Reached. That is, the invention provides a cosmetic containing stable ultramarine blue. In the stable ultramarine blue used in the present invention, the surface sulfur of the ultramarine particles is blocked with zinc salt, and this can be confirmed by ESR (electron spin resonance). Surface sulfur refers to radical sulfur that exists on the surface of ultramarine crystal lattices. This active surface sulfur decomposes under the action of acid, heat and mechanical shearing force and generates hydrogen sulfide, but if the surface sulfur combines with zinc compounds and becomes sequestered, Ultramarine is stabilized and does not decompose even when exposed to acids, suppressing the generation of hydrogen sulfide.However,
Even if the surface sulfur is blocked, there is no change in the characteristics of Gunjo Honjo, and there is no difference in color tone, basic structure, etc. between stable Ison Yangblue and untreated ones. The stable ultramarine used in the present invention is a powder, and its particle size is not particularly limited, but it is usually 0.1 to 20 particles, preferably 0.3 to 2 particles for blue particles, and 0.3 to 2 particles for reddish blue particles. It costs between 2 and 10 Buddhas. The zinc compound that sequesters surface sulfur is the same as that used in treatment, and as long as it achieves the purpose of stabilization, it does not matter whether it is inorganic or organic. Zinc complexes are also included in such zinc compounds. For example, zinc chloride,
One or more of zinc hydroxide, zinc oxide, zinc sulfate, zinc nitrate, zinc acetate, zinc citrate, etc. can be used. However, some or all of the zinc compounds may change during the treatment process; for example, zinc chloride partially changes to zinc hydroxide in the presence of caustic alkali, and this substance changes to zinc oxide when fired. Therefore, in this case, the zinc compound present in the stable ultramarine blue and the zinc compound actually used in the treatment are of different types. The amount of the zinc compound present in the stable ultramarine used in the present invention can be appropriately determined from a practical standpoint, and is about 0.1 to 2% by weight, preferably 2 to 8% by weight as zinc. If it is less than 0.1% by weight, effective stability cannot be imparted to ultramarine blue, while if it exceeds 20% by weight, the original color tone of ultramarine blue will be impaired. Although surface sulfur can be blocked only by the zinc compound, if desired, an alkali silicate or a polymeric substance may be co-present within a range that does not impair the effects of the present invention. Examples of such polymeric substances include water-soluble or water-insoluble substances, such as polyvinyl alcohol, polyacrylic acid, polyethylene glycol, polyvinylpyrrolidone, polyamide, polyvinyl acetate, and polyacrylic acid ester. The stable ultramarine blue used in the present invention may be in any form as long as the surface sulfur of the ultramarine particles is blocked with a zinc compound. Therefore, approximately the surface sulfur of ultramarine particles, whether in the form of an isolated powder, as well as in the form of a dispersion in an aqueous soot, or in a mixture with other substances, is If there is ultramarine that has been stabilized by being blocked with a zinc compound, it is still an object of ultramarine that can be used in the present invention. Ultramarine, the starting material used to produce the stable ultramarine used in the present invention, is a powder, preferably a finely ground powder that has been thoroughly ground.Usually, particles with a particle size of about 0.1 to 20 mm are used.Zinc The compounds are used as surface sulfur sequestrants, and examples of such zinc compounds include zinc chloride, zinc chloride,
Examples include zinc hydroxide, zinc oxide, zinc sulfate, zinc nitrate, zinc acetate, and zinc citrate. One or more of these can be used. Such ultramarine powder is dispersed in an aqueous soot and treated with a zinc compound. A typical aqueous medium is water, but an appropriate amount of another aqueous solvent such as methyl alcohol, ethyl alcohol, acetone, etc. may be added thereto as appropriate. Usually, about 1 to 1M volume, preferably about 4 to 6 times the amount of aqueous soot, is added to the ultramarine blue to thicken it well and disperse it uniformly to form a slurry. At this time, dispersion can be promoted by adding a dispersant or using ultrasonic waves. The slurry is preferably kept alkaline due to the nature of ultramarine. The above dispersion may be carried out at room temperature, but it may also be carried out at a temperature of about 9,000 mL for the sake of subsequent processing. For uniformly dispersed slurry,
The zinc compound, either in solid or aqueous solution form, is added slowly with careful mixing. The amount of the zinc compound added is about 0.1 to 2% by weight, preferably about 2 to 8% by weight of zinc, based on the ultramarine to be treated. If it is less than about 0.1% by weight, sufficient stability cannot be imparted to ultramarine blue, and if it exceeds about 20% by weight, the original color tone of ultramarine blue will be impaired. At this time, it is preferable to keep the pH of the slurry alkaline, and particularly when adding the zinc compound as an acidic aqueous solution, the pH is preferably adjusted to the alkaline side using caustic alkali, alkali carbonate, or the like. Unless contrary to the purpose of the present invention, alkali silicates, lagoonal polymeric substances such as polyvinyl alcohol, polyacrylic acid, polyethylene glycol, polyvinylpyrrolidone, etc., and water-insoluble polymeric substances such as polyamide, polyvinyl acetate, etc. , polyacrylic acid ester, etc., or one or more of them may be used in combination. After treatment with a zinc compound and optionally exfoliating to remove water, the treated product is obtained by oven-filtering and drying in a conventional manner. The obtained stable ultramarine blue (referred to as "raw material A") has the surface sulfur of the ultramarine particles blocked with a zinc compound, and exhibits high stability against acid, heat, and mechanical shearing force. When the thus obtained raw material A is fired, it is said to be "fired ultramarine 4 raw material B" which has an extremely high degree of stability. ) is obtained. As mentioned above, in raw material B, the active surface sulfur is blocked, and the particle surface is coated with zinc oxide as a result of calcination, so the stability against acids, heat, and mechanical shearing forces is improved. are doing. Firing is approximately 110
~25000, particularly preferably at about 2000C,
It is carried out over a period of about 0.5 to 24 hours, particularly preferably about 3 to 7 hours. In raw material B for calcined ultramarine, the particle surface is coated with zinc oxide as described above, but no matter what type of zinc compound is used in the initial treatment, as long as the treatment is carried out on the alkaline side, the particles are essentially the same after firing. Becomes super zinc oxide. In this way, the stability of the raw material B is further improved by passing through the firing process. In addition, if raw material B is further dispersed in water and then dried at a temperature of about 10 to 105°C to maintain a constant water content, and then contains an appropriate amount of water, it has extremely high stability against heat and mechanical shearing forces. Ultramarine blue (referred to as "raw material C") is obtained. To obtain raw material C, about 3 to 6 times the amount of water is added to the fired product (raw material B), and the mixture is sufficiently stirred to be uniformly dispersed, and then separated in a furnace and dried in a conventional manner. Since the purpose of this step is to impregnate the fired product with an appropriate amount of water, drying is carried out at a temperature of about 10 to 105 oo for an appropriate period of time to keep the moisture content to a certain level. The moisture content after drying can be determined as appropriate depending on the intended use of the product, but the raw material C obtained by drying at about 105° C. contains about 2% by weight of water and exhibits extremely good water dispersibility. Furthermore, in addition to manufacturing in the aqueous medium described above, it can also be obtained by uniformly mixing a zinc compound with ultramarine blue and firing the mixture. Next, specific examples of production of stable ultramarine blue used in the present invention will be given, but the present invention is not limited thereto. Production Example 1 10 parts of ultramarine blue powder were added to 50 parts of water to uniformly disperse the slurry, and the slurry was heated to 9,000 ml and maintained at pH 10 with caustic soda. Separately, a zinc chloride aqueous solution prepared by dissolving 8 parts of zinc chloride in 5 parts of water was gradually added to the slurry while stirring. During addition, the pH of the slurry was adjusted to 8 to 10. 2
After being heated for hours, the fecal matter and the treated product were washed twice with water, filtered and dried to obtain 105 parts of stable ultramarine (raw material A). ESR (Electron Spin Resonance) of the obtained stable ultramarine blue
These findings confirmed that the surface sulfur of the ultramarine particles was sequestered by zinc compounds. That is, when the ESR spectrum of untreated ultramarine was measured at room temperature, a broad and high peak of radical sulfur was detected at a value close to 2.02 needles. On the other hand, in the stable treated ultramarine, a radical sulfur peak was observed in the isotope layer, which had the same harmful spectral magnitude as that measured in the untreated ultramarine. The decrease in the magnitude of this peak indicates that the surface radical sulfur in the stable ultramarine blue of the present invention is blocked by the zinc compound. The ultramarine obtained here is
It was stable, and as shown by the results of the hydrogen sulfide detection method and silver plate blackening test described below, it was extremely superior in acid resistance and heat resistance compared to untreated products. A stable ultramarine blue (raw material A) was obtained by performing the same processing operations as in Production Example 1 under the conditions listed in the table below. Production Example 6 8 parts of zinc chloride in place of 8 parts of zinc chloride in Production Example 1
108 parts of stable ultramarine was obtained using a mixture of 5 parts of sodium silicate and 5 parts of sodium silicate. Production Example 7 10 pieces of stable Gunjo obtained in Production Example 1 were fired at 20,000 for 5 hours to obtain 98 parts of extremely stable Gunjo (raw material B). This product had adsorption ability and its surface was coated with zinc oxide. The ultramarine blue obtained here was stable and had extremely excellent acid resistance, as shown by the results of the hydrogen sulfide detection method described below. Production Example 8 Add 10 pieces of acid-resistant ultramarine (raw material B) obtained in Production Example 7 to 30 pieces of water.
The mixture was dispersed in the shell, and then separated in a furnace and dried at 105 qo to obtain 102 parts of the target product (raw material C). The surface of raw material C is coated with zinc oxide, and this material is stable and has extremely good water dispersibility.In particular, as shown by the results of the hydrogen sulfide detection method described below, it has extremely excellent acid resistance. Ta. Production Example 9 10 parts of ultramarine powder and 4 parts of zinc oxide were added and mixed uniformly in a vibrating mill for 0.5 hours, and then the mixture was heated to 20 parts.
000 for 5 hours to obtain 10 stable ultramarine blue (raw material D) grains. The ultramarine blue obtained here was stable and had extremely excellent acid resistance, as shown by the results of the hydrogen sulfide detection method described below. The stability of ultramarine blue was evaluated based on the results of the hydrogen sulfide detection method for acid resistance and the silver plate blackening test method for heat resistance. [Test method] ○ - Hydrogen sulfide detection method A 50' dropping funnel and a simple gas detection tube that can detect hydrogen sulfide are attached to a 200 top three-necked round bottom flask with a magnetic stirrer, and the detection tube is used as a water pump. Connect and always suck the hydrogen sulfide gas generated at a constant pressure. A scale is printed directly on the gas detection tube, so the amount of hydrogen sulfide can be read directly. Measurement is performed using this measuring device in the following manner. Pour 0.5 g of ultramarine into a three-necked round-bottomed flask, and disperse it uniformly in ion-exchanged water. Next, 5 portions of IN hydrochloric acid were added at once through the funnel, and the mixture was stirred using a magnetic stirrer. The amount of hydrogen sulfide (%) generated when ultramarine is dispersed by acid is read using a detection tube. (2) Silver plate blackening test method Ultramarine blue and silver plates are left at 80°C for 2 days in a sealed container, and the extent to which the silver plates darken due to the hydrogen sulfide generated during that time is observed with the naked eye. The color of the silver plate is set as 0, the overall blackening in the case of untreated ultramarine is set as 5, and the degree of blackening is scored in the range of 0 to 5. [Results and Evaluation] '1) The results of the hydrogen sulfide detection method are As shown in Figure 1. For the raw material A obtained in Production Examples 1 to 5 of the present invention and the raw material D obtained in Production Example 9, the detected amount of hydrogen sulfide after 2 minutes was 0.
In addition, raw material B in Production Example 7 and raw material C in Production Example 8 are only about 0.2 volume%, and furthermore, after 2 minutes have passed for raw materials A to C, There was no generation of hydrogen sulfide. On the other hand, untreated or sodium silicate-treated ultramarine rapidly generates hydrogen sulfide, and the amount detected after 2 minutes is about 1.3% by volume, and the detection tube is completely exhausted in less than 4 minutes. It reached the full scale of 2.0%. The above results, my dear.
The stable ultramarine blue used in the present invention is as follows:
It can be seen that the acid resistance is extremely excellent. (2- In the silver plate blackening test, the ultramarine blue A obtained in Production Example 1 of the present invention received a score of 0 (no change), whereas the untreated ultramarine blue obtained a score of 5 (full blackening). According to this result, it can be seen that the raw materials used in the present invention are extremely excellent in heat resistance.To summarize the above, all of the raw materials used in the present invention have acid resistance, It is clear that it is extremely heat resistant and therefore has remarkable stability.In the present invention, the specific stable ultramarine blue can be blended into various cosmetics as a conventional cosmetic powder. Examples include cleaning products such as soap, creams, milky lotions, packs, white powders, dusting powders, foundations, blushers, nail cosmetics, eye cosmetics, sunscreen cosmetics, deodorizing cosmetics, hair styling products, etc. The blending amount is arbitrarily selected within the range of amounts generally used as powders. All of the obtained cosmetics were stable. Next, the present invention will be explained with reference to Examples. The present invention is not limited to this.
