Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition containing a powder mixture having weak aggregation. More specifically, the powders constituting the powder cosmetics are simultaneously pulverized by using a wet medium mill to remove the solvent, whereby the agglomeration of the individual powders is released, and further different powders are formed between the powders. The present invention relates to a cosmetic composition in which a moderately mixed weakly agglomerated mixed powder is blended with a cosmetic material, which is superior in touch and color development, as compared with the case where an untreated powder is blended.

2. Description of the Related Art Conventionally, the mica titanium synthesized by the wet method has been known to be used for bonding mica particles by a treatment substance such as titanium oxide and retaining water which is often used as a solvent. It generally has a hard feel due to the cohesive force generated when it is removed.

This agglomeration is strong enough not to cause a problem in products manufactured by using media having a strong crushing force such as paint, but the crushing force is generally weak, and dry crushing is mainly used. In the field of cosmetics, it has a strength that affects the feel.

In particular, the product group such as eye shadows used around sensitive eyes has a great influence.

The present inventors used the weakly agglomerated mica titanium obtained by pulverizing mica titanium in a solvent by using a wet medium mill, and then used a weakly agglomerated mica titanium to give a feeling of cosmetics. It was found that the powder can be improved, but not only titanium mica, but also titanium oxide, iron oxide, carbon black, ultramarine blue, navy blue, and other powders can be treated at the same time. It was found that by obtaining a weakly agglomerated mixed powder containing a mixture of the above and blending it with a cosmetic, a cosmetic excellent in touch and color development can be obtained.

[0006] That is, an object of the present invention is to provide a cosmetic composition excellent in color development and touch by using a mixed powder having weak aggregation.

Sensory Evaluation Ten female panelists aged 20 to 40 were made to use the cosmetics prepared in Examples and Comparative Examples, and the number of people who answered that they had excellent color development and feel was used as an index for sensory evaluation. Therefore, the greater the number, the better the color development and touch.

Product Color Evaluation 1 g of each of the cosmetics prepared in Examples and Comparative Examples was applied to a high-quality paper.
Then, the cosmetics were crushed using another fine paper. Then, the color condition of the cosmetic was visually evaluated.

Example 1 (Eyeshadow) The composition of Table 1 was used.

[0026]

[Table 1]

(Manufacturing Method) After mixing the respective components in cyclohexane, wet milling was carried out using a paint conditioner. Glass beads were used as the grinding medium. After cyclohexane was heated and distilled off under reduced pressure from the obtained dispersion liquid, the obtained powder was roughly crushed with a mixer and pressed on a metal plate to obtain a brown eye shadow.

Comparative Example 1 (Eye Shadow) The components of Example 1 were mixed with a mixer and pressed on a gold plate to obtain a brown type eye shadow.

Table 2 shows the results of the sensory evaluation of Examples and Comparative Examples.

[0030]

[Table 2]

From the results shown in Table 2, it was found that the examples were superior in color development and touch to the comparative examples. Also,
From the impression of the panelists, it was found that the examples of the present invention have improved spreadability and softness as compared with the comparative examples.
