Description

[Detailed description of the invention]

The present invention relates to a make-up cosmetic containing a colored processed powder that maintains the surface characteristics of an organic powder and has an unprecedented coloring effect. Conventionally used inorganic or organic powders for cosmetics include talc, kaolin, titanium dioxide, zinc oxide, sericite, synthetic mica, muscovite, magnesium carbonate, calcium carbonate, bentonite, magnesium silicate, etc. Inorganic powders and organic powders include microcrystalline cellulose, silk powder, nylon powder, polyethylene powder, stearic acid, magnesium, and zinc myristate, but most of them are white to whitish-gray in color. These powders are usually Red No. 226, Red No. 202, Red No. 206
No., orange No. 203, yellow No. 4 aluminum rake,
The desired color of cosmetics can be achieved by mixing organic pigments such as carbon black or inorganic pigments such as yellow iron oxide, red iron oxide, purple iron oxide, black iron oxide, ultramarine blue, mango violet, chromium oxide, and chromium hydroxide. Allows selection of desired colors. However, in mixed cosmetics made from a combination of several raw materials, the color changes during production, storage, and transportation due to differences in crystal form, affinity, specific gravity, particle size distribution, surface activity, etc. between the powder and pigment. Usually, separation, segregation, color spots, etc. occur and the quality of the product is significantly degraded. Furthermore, even when cosmetics are actually applied to the skin, the pigments tend to lose their wetness over time due to oil, water, salt, etc. secreted on the skin surface, resulting in a darker color. Even if it becomes slightly transparent when wet, it still appears white or whitish-gray, which causes color separation on the skin surface, resulting in poor adhesion and a floating feeling on the skin. There is a drawback that
It was not desirable. As a result of various experimental studies aimed at solving the above-mentioned drawbacks, the present inventors have discovered a cosmetic that does not have these drawbacks. In the present invention, an organic powder is dispersed in purified water without or using an acid, a solution of a colored metal compound previously dissolved in an acid or purified water is added, and then an alkali is added to the solution while stirring. The colored metal hydroxide is deposited on the surface of the organic powder, and the colored metal hydroxide is taken out, washed with water, and dried to give a pH of 0.5 to 98.
The present invention relates to a make-up cosmetic containing %. In the colored processed powder applied to the present invention, the composition ratio of organic powder and colored metal compound is 1:
A range of 0.01 to 1:0.6 is appropriate, and cosmetics containing more of the former are more susceptible to changes over time, and also have a "lifting" finish, which is the object of the present invention. Not suitable for Furthermore, if the latter is present in large quantities, the "dullness" characteristic of colored metal compounds will be intensified, making it impossible to impart desirable cosmetic effects. The organic powder to be applied to the colored powder of the present invention is acid-resistant, alkali-resistant, and insoluble, such as silk powder, dextran sulfate, water-insoluble collagen, cellulose powder, ethyl cellulose, propyl cellulose. , cellulose derivatives such as butylcellulose, nylon powder, starch and its derivatives, distylbenzene pinhole polymer, benzoguanamine powder, polyethylene powder, tetrafluoroethylene, etc., but those with an average particle size of 0.2μ to 50μ preferable. In the colored processed powder used in the present invention, these organic powders can be used in combination with the inorganic powder used to obtain the colored processed powder described in Japanese Patent Application No. 154208/1982. When organic powder and inorganic powder are combined in this way, colored metal hydroxides are deposited on the surfaces of each of the organic powder and inorganic powder as a result of the colored processed powder manufacturing method described below. is obtained.

Cobalt hydroxide, manganese hydroxide, etc., and colored metal chlorides include ferrous chloride, ferric chloride, cobalt chloride, manganese chloride, etc. Next, details of the method for producing colored processed powder applied to the present invention will be explained. Method: 100 to 1000 parts of purified water at 5° to 80°C, optionally with 0.1 to 10% by weight of water-soluble silicate and/or water-soluble activator to improve dispersibility, and a type of organic powder. Alternatively, gradually add 10 to 100 parts of two or more with stirring, continue stirring for an additional 15 minutes to 3 hours to disperse, and then add sulfuric acid, nitric acid,
Inorganic acid such as hydrochloric acid (0.01-5N) or purified water 100%
~1000 parts of a solution of a colored metal compound previously dissolved is gradually added while stirring so that the ratio of organic powder to colored metal compound is 1:0.01 to 1:0.6. While stirring for another 10 minutes to 3 hours (air may be introduced here if necessary).0.01~
When the powder is moved to an alkaline range of PH7.5 to 13.0 using an alkali such as 1N ammonia water, sodium hydroxide, or potassium hydroxide, colored metal hydroxides are deposited on the surface of the powder (impregnation adsorption). Thereafter, this is taken out, washed with water, and dried with air or hot air at 40 to 100°C to obtain a colored processed powder. Method: 100 to 1000 parts of purified water at 5° to 80°C, optionally with 0.1 to 10% by weight of water-soluble silicate and/or water-soluble activator to improve dispersibility, and a type of organic powder. Alternatively, 10 to 500 parts of two or more of them are gradually added with stirring, and the stirring is continued for an additional 10 minutes to 5 hours to disperse them. Adjust the pH to an acidic range of 2.5 to 6.5 using 0.01 to 3N), and while stirring thoroughly, add 30 to 1000 parts of an inorganic acid such as sulfuric acid, nitric acid, or hydrochloric acid (0.01 to 3N) or purified water. A solution of a colored metal compound pre-dissolved in the organic powder and the colored metal compound in a ratio of 1:0.01 to
Gradually add this while stirring so that the ratio is 1:0.6, and then add 0.1 to 5N ammonia water while continuing to stir (air may be introduced here if necessary).
When the powder is brought to an alkaline range of 7.5 to 13.0 using an alkali such as sodium hydroxide or potassium hydroxide, colored metal hydroxides are deposited on the surface of the powder.
Thereafter, it is taken out, washed with water, and dried in air or hot air at 40° to 100°C to obtain a colored processed powder. The water-soluble silicates used during the manufacturing process of the colored processed powders mentioned above include sodium silicate, sodium orthosilicate, sodium sesquisilicate hydrate, sodium metasilicate, sodium trisilicate, sodium tetrasilicate, potassium metasilicate, metasilicate. Examples include potassium hydrate, potassium disilicate, disilicate hydrate, tetrasilicate hydrate, potassium orthosilicate, lithium orthosilicate, lithium disilicate, lithium tetrasilicate, ammonium orthosilicate, and ammonium metasilicate.
