Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a resin by blending a resin powder having an average particle size of 1 to 100 microns whose surface is covered with an inorganic powder having an average particle size of 0.01 to 5 microns. A non-liquid makeup make-up with a beautiful finish that does not impair the smoothness and lightness that powder imparts to usability, and has a covering power, and also suppresses the uneven color, color drift, and color separation that occur when applied to the skin. Regarding fees.

[Conventional technology]

Non-liquid makeup cosmetics are usually produced by blending oils, waxes, hydrocarbons, oily bases such as higher alcohols, powders and colorants with other ingredients such as antioxidants, plasticizers, solvents and the like. There is. Further, a resin powder is blended in order to impart lightness of sliding and a good feeling.

[Problems to be solved by the invention]

However, since the resin powder has a low refractive index, it has no hiding power when blended with a non-liquid makeup cosmetic. As a result, there is a large difference in the hiding power from the pigment having a high refractive index, which causes streaking and greatly impairs the beauty of the finished product. In addition, there is a problem that color unevenness and color floating occur when used in combination with a coloring pigment.

[Means for solving problems]

Therefore, in view of the above circumstances, the present inventors have a covering power and suppress color unevenness that occurs when applied to the skin, without impairing the good slipperiness and lightness imparted to the usability of the resin powder. As a result of intensive research to obtain a clean non-liquid makeup cosmetic product, it was found that this problem can be solved by adding a resin powder whose surface is covered with an inorganic powder to the cosmetic product. Has been completed.

As the inorganic powder applied in the present invention, those used in cosmetics are arbitrarily used, and examples thereof include the following inorganic powders.

That is, talc, titanium oxide, mica, zinc oxide, kaolin, zirconium oxide, chromium oxide, cobalt oxide, red iron oxide, yellow iron oxide, black iron oxide, barium sulfate, bismuth oxychloride, manganese, navy blue, ultramarine blue, hydroxylation Chromium, aluminum hydroxide, aluminum silicate,
Examples thereof include anhydrous silicic acid, hydrous silicic acid, aluminum, copper, gold and titanium mica.

Examples of the resin powder applied in the present invention include polyester, polyethylene, polystyrene, methyl methacrylate resin, cellulose, 12 nylon, 6 nylon, a copolymer of styrene and acrylic acid, polypropylene, vinyl chloride and Teflon. .

In the present invention, the average particle size of the inorganic powder is 1/1000 to 1/5 of the average particle size of the resin powder, and the inorganic powder covers the surface of the resin powder by using the inorganic powder having the particle size in such a range. Will be able to do it. The particle size of the inorganic powder is usually 0.01-
A range of 5 microns, especially a range of 0.01 to 1 micron is preferred. The particle size of the resin powder is usually 1 to 100.
Microns, especially those in the range of 3 to 30 microns are preferred.

In order to produce the composite powder to be mixed in the cosmetic of the present invention, the inorganic powder and the organic powder are mixed in a dry or wet manner to produce a powder in which the inorganic powder is uniformly adhered to the surface of the resin powder. . As the mixing device, various ball mills, pot mills, emulsification basins, electric crushers, attritors and the like are applied. Alternatively, it is manufactured by embedding an inorganic powder inside the resin powder when manufacturing the resin powder.

The amount ratio used when mixing the inorganic powder and the resin powder is 0.1 to 200 parts of the inorganic powder to 100 parts of the resin powder.

〔Example〕

Next, the present invention will be specifically described with reference to examples.
The present invention is not limited to this, and can be applied to all non-liquid makeup cosmetics. The blending amount is% by weight.

Example 1 Dual-use foundation 40% Titanium oxide coated cellulose 15 Silicon treated mica 40 Silicon treated talc 20.45 Silicon treated iron oxide 6.5 Titanium oxide 5 Trimethylolpropane triisostearate 5 Squalane 3 Beeswax 2 Sorbitan trioleate 1 Preservative 0.5 Vitamin E 0.05 butyl methoxybenzoyl methane 1 fragrance 0.5 (production method) was mixed with a Henschel mixer, and the mixture obtained by heating and mixing with was added and mixed, and the mixture was crushed and molded into a medium plate to obtain a dual-use foundation. In Example 1, there was a covering power, but the spreadability was light and the finish was beautiful.

Example 2 Oily Stick Foundation Titanium oxide 6 40% Titanium oxide coated nylon powder 7 Kaolin 12 Talc 13.7 Red iron oxide 1 Yellow iron oxide 0.7 Black iron oxide 0.1 Squalane 37 Cetyl 2-ethylhexanoate 16 Sorbitan sesquioleate 1 Aristo wax 4 Carnauba wax 1.3 Fragrance 0.2 (manufacturing method), and are mixed at 80 ℃, this ,,,,,
, And are added, mixed with a disper, and then TK milled. And are melted by heating, added and mixed, and then degassed. After gently mixing, fill the container at 80 ° C,
A stick foundation was obtained by cooling.

Comparative Example 1 In the formulation of Example 2, a product obtained by substituting nylon powder for (2) was prototyped by the same method as in Example 2. The sensory evaluation results of Example 2 and Comparative Example 1 are shown in Table 1. As for the evaluation method, a sensory evaluation of 5 grades from 1 to 5 was carried out by 10 professional panelists, and the average value was represented by the following symbols.

◎ …… 4.5 to 5.0 ○ …… 3.5… 4.4 △ …… 2.5 to 3.4 × …… 1.5 to 2.4 × × …… 1.0 to 1.4 As is clear from Table 1, the stick foundation according to the present invention is excellent in all sensory evaluation items.
