DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a colored spherical polyamide powder and a colored spherical polyamide powder which are compounded as a coloring agent in cosmetics such as foundation, eyeshadow, eye lighter, blusher or nail polish. Related to cosmetics.

No., Purple No. 201, etc. are dyes and, when blended in cosmetics, are generally used as dyeing lakes by coloring extenders such as precipitated barium sulfate, aluminum hydroxide, calcium carbonate, clay and the like. ing.

[0003] On the other hand, in recent years, in order to suppress the elution property of water, Japanese Patent No. 1426369 and Japanese Patent No. 2543 have been disclosed.
A method of intercalating an organic dye molecule between layers of a layered inorganic compound such as smectite has been attempted by the methods disclosed in JP-A-205-205 and JP-A-8-302230.

[0004]

However, in the case of the above-mentioned organic acid dye-dyed extender pigment lake, although the coloring property is excellent, the organic acid dye is eluted in water or used depending on the original shape of the extender pigment. There is a problem that the feeling changes.

Further, a composite inorganic compound in which an organic acid dye is intercalated between the layers of smectite produced by a method as disclosed in Japanese Patent No. 1426369, Japanese Patent No. 2543205, Japanese Patent Application Laid-Open No. 8-302230, and the like. Although the solubility in water is improved compared to dyed lakes, the smectite compound has a very poor feel even when crushed, and the organic acid dye fixed by these methods is limited. There is a problem that not all organic acid dyes can be fixed.

The present invention has been made in order to solve such a problem. By dyeing a spherical polyamide powder with an organic acid dye, the coloring property is good and the elution property to water is very low. Further, it is an object of the present invention to provide a colored spherical polyamide powder for cosmetics which is excellent in use feeling and to provide a cosmetic containing the colored spherical polyamide powder.

[0007]

In order to achieve the above object, the colored spherical polyamide powder according to the first invention has an average primary particle diameter of 0.1 μm or more and 50 μm.
m or less spherical polyamide powder is dyed with an organic acid dye.

[0008] According to the colored spherical polyamide powder of the present invention, generally, a nylon fiber or a nylon woven fabric is dyed by a method similar to the method of dyeing with an organic acid dye. Ink, can be contained as a composition such as rubber toner, especially makeup cosmetics, for example, foundation, eyeshadow, eye runner,
It can be contained in cosmetics as a coloring agent such as blusher or nail polish. Further, the average primary particle size is 0.1.
Since the polyamide powder having a particle size of 1 μm or more and 50 μm or less is dyed with an organic acid dye, the coloring property is excellent, the dissolution of the organic acid dye in water is very low, and the shape of the polyamide powder is spherical. Because of this, it has very excellent characteristics in use (first invention).

In the present invention, the organic acid dye is preferably contained in a colored spherical polyamide powder in an amount of 0.1% by weight or more (second invention). If the amount is less than 0.1% by weight, excellent color developability is not exhibited, which is not preferable.
On the other hand, the upper limit of the content of the organic acid dye is not particularly limited, but if it exceeds 30% by weight, there is a problem that it elutes in water depending on the type of the dye.

Next, a third invention relates to a cosmetic containing the colored spherical polyamide powder according to the first or second invention. Cosmetics containing the colored spherical polyamide powder of the present invention, especially make-up cosmetics, such as foundation, eyeshadow, eyeliner,
Cosmetics such as blusher or nail polish have good coloring properties and very low solubility of organic acid dyes in water.Therefore, there is no problem that skin is stained with dyes. As a result, it is possible to obtain a cosmetic having an excellent feeling upon use.

EXAMPLES Next, specific examples of the colored spherical polyamide powder and the cosmetic containing the powder according to the present invention will be described.

(Production Example 1) Using spherical nylon 12 having an average primary particle size of 6 μm as a raw material, Red No. 104 was completely dissolved in warm water at 50 to 60 ° C. so as to have a concentration of 10%, and then cooled. Red No. 104 is spherical nylon 12
The powder was added to the raw material spherical nylon so as to be 8% by weight, heated to 80 ° C. with stirring, and heated for about 1 hour. At this time, a small amount of glue was added as an anti-crying agent. Thereafter, the mixture was filtered, washed twice with warm water, dried, and then pulverized with a pulverizer to obtain spherical nylon 12 powder dyed with Red No. 104.

(Production Example 2) Average primary particle system 10 μm
Was prepared in the same manner as in Production Example 1 except that Yellow Nylon 6 was used as a raw material and Yellow No. 4 was used as an organic acid dye.

(Production Example 3) The same spherical nylon 12 powder as in Production Example 1 was used.
A spherical nylon 12 powder dyed with Blue No. 1 was obtained in the same manner as in Production Example 1 except that No. 1 was used.

(Comparative Examples 1 to 3) Les Co of France
Red 1 commercially available from lorants Wackerr
No. 04 aluminum lake, yellow No. 4 aluminum lake, blue No. 1 aluminum lake were compared with Comparative Examples 1 to 1, respectively.
It was set to 3.

Hereinafter, specific examples in which cosmetics are actually blended using the colored spherical nylon 6 and nylon 12 powders obtained in the above-mentioned production examples 1 to 3 will be described.

With respect to the colored spherical polyamide powders of Production Examples 1 to 3 obtained as described above and the aluminum lakes of Comparative Examples 1 to 3, a dissolution test for water and a quantification of good feel were performed. The angle of repose of the powder was measured with a powder tester manufactured by Hosokawa Micron Corporation, and the results are summarized in Table 1. In addition, as a method of the dissolution test for water, 1 g of each of the above powders was placed in 50 g of purified water, stirred for 1 hour with a magnetic stirrer, and then treated at 5000 rpm for 5 minutes using a centrifuge. 5
The solution was filtered through filter paper C, and the light transmittance of the filtrate at the specific absorption wavelength of each dye was measured with a spectrophotometer. (The specific absorption wavelength of each dye is 540 n in the case of Red No. 104
m, 428 nm for Yellow 4 and 632 for Blue 1
nm. )

[Table 1]

As is apparent from the results in Table 1, colored spherical polyamide powder dyed with an organic acid dye (Production Example 1)
In (3), the transmittance of each organic acid dye is higher than that of aluminum lake, and it can be seen that the elution property of water to water is small. In addition, the angle of repose is about 20 degrees lower than each aluminum rake,
It was confirmed that the fluidity of the powder was high.
