It is known to be incorporated into products. Japanese Patent Application Laid-Open No. 61-7207 discloses a cosmetic composition containing an inorganic pigment surface-treated with an N-mono long chain acyl basic amino acid.
[0003]
[Problems to be solved by the invention]
However, the use of agar as a pigment coating agent and the properties of pigments coated with agar and N-acylated lysine have not been known. Also, when the agar-coated pigment is used in cosmetics, a good coating feel is obtained when there is little or moderate moisture on the skin, but when a large amount of moisture is present on the skin In some cases, the agar coating-treated pigment was too close to the skin and the feel deteriorated.
That is, an object of the present invention is to provide a makeup cosmetic that is excellent in durability of the makeup effect, uniformity and feel (softness) during application.
[0004]
[Means for Solving the Problems]
In view of these problems, the present inventors have studied a technique that can successfully control the water absorption and adhesiveness of an agar-coated pigment even when a large amount of water is present. As a result, N-acylated lysine is used together with agar to carry out a coating treatment without impairing the characteristics of the agar-coated pigment, and the resulting product is durable. The present invention was completed by finding that the touch (softness) at the time of application was excellent.
[0005]
That is, the present invention is a makeup cosmetic characterized by blending agar and a treated pigment coated with N-acylated lysine.

[0023]

[0024]
Production Example 1 of Coated Pigment
Each of Bengala, yellow iron oxide, black iron oxide, titanium oxide, and barium sulfate was subjected to a composite treatment by the following method. 5 parts by mass of N-lauroyl-L-lysine was dissolved in an alkaline solution consisting of 9 parts by mass of 5 mol / L sodium hydroxide and 64 parts by mass of purified water. 92 parts by mass of each pigment was added to an acidic solution composed of 6.9 parts by mass of 6 mol / L hydrochloric acid and 700 parts by mass of purified water, and stirred well to obtain a slurry. While stirring the slurry, the N-lauroyl-L-lysine solution was added dropwise in a short time, the pH was finely adjusted, filtered and washed with water. Next, using a solution in which 3 parts by mass of agar was dissolved in 100 parts by mass of purified water at 90 ° C., the water-washed powder was slowly added with stirring and kneaded under heating. The obtained powder was dried at 90 ° C. for 10 hours using a blower dryer and then sterilized at 120 ° C. for 3 hours. Subsequently, the mixture was pulverized using an atomizer to obtain the target agar / lauroyllysine composite-coated pigment.
[0025]
Production Example 2 of Coated Pigment
For each of talc, sericite, and polymethyl methacrylate powder (spherical powder), 92 parts by mass of pigment was heated using a planetary mill in a solution in which 4 parts by mass of agar was dissolved in 130 parts by mass of purified water at 90 ° C. Mixed. When the whole became uniform, the paste-like pigment was transferred to a stainless steel vat, and then dried at 90 ° C. for 12 hours in a blower dryer. After roughly mixing the obtained powder and 4 parts by mass of N-lauroyl-L-lysine, a mechanochemical reaction was mechanically generated using a ball mill to obtain a target agar / lauroyllysine composite-coated pigment. .
[0026]
Example 1, Comparative Examples 1-2 (powder foundation)
A powder foundation was prepared according to the formulation in Table 1 and the following production method.
However, as the agar / lauroyllysine composite-coated pigment, the pigment produced in the above Production Examples 1 and 2 (in terms of the blending ratio of untreated raw materials) mixed at the following blending ratio was used. As the untreated pigment, the same pigment as that prepared in the production example was used in an untreated state. As the N-lauroyllysine-treated pigment, an 8% by mass wet surface-treated pigment was used. In addition, the unit of a compounding quantity is a mass part.
[0027]

[0028]

An oily foundation was prepared according to the formulation in Table 2 and the following production method.
However, as the agar / lauroyllysine composite-coated pigment, the pigment prepared in the above production example (in terms of untreated pigment) mixed at the following blending ratio was used. As the untreated pigment, the same pigment as that prepared in the production example was used in an untreated state. As the N-lauroyllysine-treated pigment, an 8% by mass wet surface-treated pigment was used.

[0033]
(Production method)
The oil component was heated and mixed, added slowly from above the powder component previously mixed, and further stirred, and then passed through a 60 mesh and cast into a metal dish using a mold to obtain a product.
[0034]
From the results shown in Tables 1 and 2, it can be seen that each example of the present invention is superior to each comparative example in the long-lasting effect of the makeup, the uniform finish, and the softness during application. On the other hand, in the comparative example using the untreated pigment and the N-lauroyllysine-treated pigment, the evaluation deteriorated in any item.
