Embodiments of the present invention will be described below. The makeup cosmetic of the present invention contains the above N
-An acyl amino acid (I) is incorporated. N- of the above-mentioned N-acylamino acid compounded in the makeup cosmetic of the present invention
Examples of the acyl group R ¹ include a saturated aliphatic monocarboxylic acid group such as a lauroyl group, a myristoyl group, a palmitoyl group, and a stearoyl group, a saturated aliphatic dicarboxylic acid group, an unsaturated aliphatic carboxylic acid group, and a carbocyclic group. A carboxylic acid group or the like can be used as long as the safety of a makeup cosmetic containing the N-acylglutamic acid having the N-acyl group R is not hindered.

Of these, the case where the N-acyl group R ¹ is a saturated aliphatic carboxylic acid group is preferred in that the desired effect of the present invention can be easily exerted by its combination. When the number of carbon atoms of these saturated aliphatic carboxylic acid groups is 12 or more and 18 or less, for example, the above-mentioned lauroyl group, myristoyl group, palmitoyl group,
In the case of a stearoyl group or the like, that is, when R ^{2 of} N-acylamino acid (I) is a group HOOC (CH ₂ ) ₂ —,
When it is acyl glutamic acid, N- lauroyl glutamic acid, N- myristoyl glutamic acid, N- palmitoyl glutamic acid, when it is N- stearoylglutamic acid; when also R ² is is N- acyl glycine hydrogen atoms, N- lauroyl glycine , N
-Myristoyl glycine, N-palmitoyl glycine,
The case of N-stearoyl glycine is particularly preferred in that the intended effect of the present invention can be particularly remarkably exhibited.

It is also possible to combine two or more of the above-mentioned N-acylamino acids (I) in the external preparation for skin of the present invention, and to use fatty acids derived from naturally occurring materials (for example, coconut). Oil fatty acids, tallow fatty acids, etc.)
N-acylglutamic acid or N-acylglycine bonded to glutamic acid or glycine as an acyl group can also be blended as the N-amino acid (I).

The N-acylamino acids (I) according to the present invention are those produced according to a generally known method such as "acting an acid chloride or acid anhydride on an alkaline aqueous solution of an amino acid to be N-acylated". Although it is possible to mix it into makeup cosmetics, it is of course possible to use commercially available products.

Such commercial products include, for example, Amisoft LA (N-lauroylglutamic acid), Amisoft MA
(N-myristoylglutamic acid), Amisoft HA
(Hardened beef tallow fatty acid glutamic acid), Amisoft CA (coconut oil fatty acid glutamic acid) (all manufactured by Ajinomoto Co., Inc.)
And the like.

The above-mentioned N-acylamino acid (I)
Salts of, for example, sodium salts, potassium salts, triethanolamine salts and the like can also be produced by a generally known method,
It is already commercially available. However, these N-
The salt of the acylamino acid (I) is added to the makeup cosmetic,
Even if it is blended with the hydrophobizing powder described later, the makeup cosmetics can be easily washed off, but the makeup durability, which is a more necessary element for makeup cosmetics, tends to deteriorate, which is not preferable.

Therefore, when the salt of the N-acylamino acid (I) is blended into the make-up cosmetic of the present invention, an acid which can be blended into the make-up is used as a pH adjuster in view of safety and the like. In many cases, it is necessary to take measures such as inclusion in cosmetics.

The amount of the N-acylamino acid (I) in the make-up cosmetic composition of the present invention is 0.1% based on the total amount of the cosmetic preparation.
It is necessary that the content be 1% by weight or more. In particular, in order to improve the durability of the makeup and facilitate the washing off, it is preferable to add 1.0% by weight or more of the whole cosmetic.

The upper limit of the compounding amount is not particularly limited from the viewpoint of exhibiting the desired effect of the present invention, but when the N-acyl amino acid (I) is added in a remarkably excessive amount, In addition to the tendency not to show the effect corresponding to, there is a tendency to cause problems in usability, such as heavy spread when applied on the skin, or to adverse effects such as precipitation during storage. It is necessary to keep in mind. If the upper limit of the content of the N-acyl amino acid (I) is dared to be set from this point, it is 10.0% by weight based on the whole cosmetic.
It is about.

The makeup cosmetic of the present invention is blended with a hydrophobizing powder together with the N-acylamino acid (I). In the present invention, the “hydrophobized powder” means a powder obtained by applying a hydrophobic treatment to a powder component used in general makeup cosmetics to impart water repellency.

Here, powder components used in general makeup cosmetics include, for example, talc, kaolin, sericite, calcium carbonate, zinc white, titanium dioxide, red iron oxide, yellow iron oxide, black iron oxide, ultramarine, Titanium coated mica, Bismuth oxychloride, Bengala, Binder pigment, Gunjo pink, Chromium hydroxide, Mica titanium, Chromium oxide, Aluminum cobalt oxide, Carbon black, Silicic anhydride, Magnesium silicate, Bentonite, Mica, Zirconium oxide And the like, but are not limited thereto.

The hydrophobizing treatment applied to the powder component includes a high-viscosity silicone oil treatment and a silicone resin treatment in which an alkyl hydrogen polysiloxane is reacted. Examples of the method include generally known hydrophobic treatments such as an alkene treatment, a wax treatment, a dextrin fatty acid treatment, and a fluorine treatment performed after the silicone oil treatment or the silicone resin treatment.

Thus, the hydrophobized powder prepared by the above-mentioned hydrophobizing method can be incorporated into the makeup cosmetic of the present invention. In addition, the kind of the above-mentioned hydrophobizing powder mixed into the makeup cosmetic of the present invention can be appropriately selected according to individual and specific circumstances such as a balance with other compounding components. In addition, only one type of the above-mentioned hydrophobized powder can be blended in the makeup cosmetic of the present invention, but it is also possible to blend two or more types in combination.

The amount of the hydrophobized powder in the make-up cosmetic of the present invention is not particularly limited in that the desired effect of the present invention is exclusively exerted, and the desired amount of the make-up cosmetic of the present invention is not limited. It is appropriately selected according to the specific dosage form.

Considering the dosage form of a makeup cosmetic that is generally manufactured, it accounts for 1.0% by weight or more of the total amount of the cosmetic.
In the range of about 0.0% by weight or less, the above-mentioned hydrophobized powder is incorporated into the makeup cosmetic of the present invention. However, it does not deny the possibility that the above-mentioned hydrophobized powder may be added to the makeup cosmetic of the present invention outside the above-mentioned mixing range.

For example, even if the above-mentioned hydrophobized powder exceeds 80.0% by weight of the total cosmetic composition, a particularly positive disadvantage is recognized as long as the amount is appropriate in the dosage form. It is not something that can be done. Further, even when the hydrophobic treatment powder is used in less than 1.0% by weight of the whole cosmetic, the cleansing properties of the cosmetic can be maintained.

Thus, the N-acyl amino acid (I)
When the hydrophobic treatment powder is blended into the makeup cosmetic, excellent water repellency due to the blending of the hydrophobic treatment powder is imparted to the makeup cosmetic of the present invention, and a makeup cosmetic excellent in makeup durability is provided. You. And
During washing, the N-acylamino acid (I) is neutralized by a face wash, which is generally an alkali, to form a salt, and as a result, it is easy to wash off.

That is, the N-acyl amino acid (I)
By blending the above-mentioned hydrophobic treatment powder and makeup cosmetics, while maintaining the desired cosmetic durability,
A makeup cosmetic which is easy to wash off is provided.

In the makeup cosmetic of the present invention, the N-acylamino acid (I) and the hydrophobized powder are pharmaceutically acceptable bases corresponding to the desired dosage form, such as water, lower alcohol, and the like. It can be used as a mixture with oils, emulsifiers, gelling agents, thickeners, chelating agents, preservatives, fragrances and the like.

Further, as long as the makeup cosmetic of the present invention is intended only for the intended effects of the present invention, it is not particularly necessary to additionally mix other medicinal ingredients. However, for the purpose of imparting an effect that a makeup cosmetic will generally exhibit by blending other medicinal ingredients, blending this other medicinal ingredient into the makeup cosmetic of the present invention depends on the combination. It is possible within a range that does not impair the intended effect.

For example, pharmaceutically active ingredients such as humectants, ultraviolet absorbers, vitamins and the like can be incorporated into the makeup cosmetic of the present invention according to the purpose. INDUSTRIAL APPLICABILITY The present invention can be widely applied to dosage forms possible as makeup cosmetics, for example, liquid, emulsion, cream, stick, etc.
Gel, pact, two-phase separated, three-phase separated, solid, etc.
