TECHNICAL FIELD The present invention belongs to the technical field of cosmetics. More specifically, it belongs to the technical field of makeup cosmetics having excellent makeup retention.

[0002]

2. Description of the Related Art In general, makeup cosmetics have an aesthetic role that makes people look beautiful, a protective role that protects human skin, and a psychological role that makes people feel motivated and creates vitality for further activities. Although there are roles and the like, makeup cosmetics having poor makeup retention cannot sufficiently fulfill any of these roles. In other words, even when using cosmetics that make the makeup last longer, it becomes difficult to play the above-mentioned aesthetic role and protective role in a short time, and the user feels anxious about "when makeup will be worn out". It is difficult to get rid of rashes, and it is difficult to energize further activities, so it is difficult to play the above-mentioned psychological role. Therefore, "how to make makeup last longer" is a very important concern when developing a new makeup cosmetic. Also, summer in Japan is hot and humid,
Excretion of sebum and sweat, which is the main factor causing makeup loss, increases.

From such a point of view, conventionally, there has been provided a means for providing makeup cosmetics which suppresses various kinds of makeup deterioration and has excellent makeup retention. For example, a method of suppressing sebum secretion by incorporating repulinic acid or a salt thereof into makeup cosmetics (JP-A-59-164712); by incorporating spherical porous resin powder into makeup cosmetics. Method of absorbing sweat and sebum
No. 5-172580); and active zinc white and pyridoxine and / or pyridoxine derivatives in cosmetics to improve the makeup lasting (Japanese Patent Laid-Open No. Sho 6-62).
No. 2-56415) has already been provided. However, although all of these means can make the makeup last longer to some extent, it cannot be denied that it is necessary to provide makeup cosmetics having even better makeup lasting.

[0004]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide a makeup cosmetic composition which is more excellent in makeup retention.

[0005]

In view of the above-mentioned problems, the present inventor has made earnest studies to obtain a makeup cosmetic having excellent makeup retention, and as a result, activated zinc white and an organopolysiloxane having a specific particle size have been obtained.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. A. The "active zinc white" blended in the makeup cosmetic of the present invention is zinc white having a larger specific surface area than the conventional zinc white, and has been conventionally used as a white pigment or the like.
Specifically, conventional methods such as an "indirect method" in which metallic zinc is dissolved and evaporated and then oxidized, and a "direct method" in which zinc ore is reduced and roasted with coke to metallic zinc and then oxidized The specific surface area of the zinc white obtained by the method is generally less than 15 m ² / g, whereas the specific surface area of the active zinc white used in the present invention is usually 25 m ² / g or more. This active zinc white can be obtained by, for example, a “wet method” in which a zinc sulfate or zinc oxide solution is reacted with a soda ash solution, and the reaction product is baked and ground.

However, the active zinc white produced by the above-mentioned wet method may have some basic zinc carbonate remaining depending on the firing conditions. If the amount of the basic zinc carbonate remaining is too large, the Inventive makeup cosmetics tend not to exhibit the desired effect of improving the makeup retention. Therefore, the preferred active zinc white used in the present invention is a zinc oxide equivalent (JIS K1).
410) 75% by weight based on the total active zinc white
The above is activated zinc white. When the equivalent amount of zinc oxide is less than 75% by weight in the whole active zinc white, that is, the residual amount of the basic zinc carbonate is 25% by weight or more of the whole active zinc white, in the makeup cosmetic of the present invention as described above, It is not preferable because it tends to be difficult to sufficiently bring out the desired effect of improving makeup retention.

In the present invention, it is also possible to use a commercial product of activated zinc white. Specifically, for example, activated zinc white Azo-, Azo-B (manufactured by Shodo Kagaku) or Z
INCA # 20 (manufactured by Sakai Chemical Industry Co., Ltd.) or the like can also be used.

The amount of the active zinc white compounded in the makeup cosmetic composition of the present invention should be specifically determined depending on the specific form of the cosmetic composition and the extent to which the makeup retention is improved. Although not particularly limited, it is generally mixed in the range of 0.1% by weight or more and 50% by weight or less with respect to the entire cosmetic.

If the amount is less than 0.1% by weight with respect to the total amount of the cosmetic, it is not preferable because the makeup retention cannot be sufficiently improved. On the other hand, if the blending amount exceeds 50% by weight with respect to the total amount of the cosmetic composition, the makeup cosmetic composition obtained becomes powdery, spreads heavily, and is uncomfortable to use, which is not preferable.

Further, the makeup cosmetic of the present invention, in which the amount of the active zinc white compounded is in the range of 2.0% by weight or more and 8.0% by weight with respect to the total amount of the cosmetic, has a particularly long-lasting effect on makeup retention. In addition, the feeling of use is good, and it is particularly preferable.

B. The “organopolysiloxane elastomer spherical powder having an average particle size of 1.0 μm or more and 15.0 μm or less” to be incorporated into the makeup cosmetics of the present invention originally improves makeup retention and smoothes the feeling of application to the skin. It is a component added to cosmetics for the purpose of lightening the spread and giving a refreshing and moisturizing feel. However, even if this organopolysiloxane elastomer spherical powder was blended alone into a makeup cosmetic composition as a component for improving makeup retention, the effect was not undeniable (Examples and Comparative Examples described later). checking).

If the average particle size of the above-mentioned organopolysiloxane elastomer spherical powder is less than 1.0 μm, the smoothness of the makeup cosmetic compounded with the powder tends to decrease, which is not preferable, and if it exceeds 15.0 μm. Makeup cosmetics containing this tend to lack a moisturizing feel and are not preferred.

For reference, the outline of the method for producing the spherical powder of organopolysiloxane elastomer will be described. The organopolysiloxane elastomer spherical powder is produced by using a curable organopolysiloxane composition as a main component and a method depending on the type of the composition selected. The curable organopolysiloxane composition is, for example, an addition product prepared by curing a silicon atom-bonded hydrogen atom-containing diorganopolysiloxane and a silicon atom-bonded vinyl group-containing organopolysiloxane by an addition reaction in the presence of a platinum-based catalyst. Reaction-curing organopolysiloxane composition; condensation reaction in which diorganopolysiloxane having hydroxyl groups at both ends of the molecular chain and diorganopolysiloxane having silicon-bonded hydrogen atoms are dehydrogenated in the presence of an organotin compound to cure Curable organopolysiloxane composition; a condensation reaction in which a diorganopolysiloxane having hydroxyl groups at both ends of a molecular chain and a hydrolyzable organosilanecarboxylic acid are subjected to a condensation reaction in the presence of an organotin compound or titanate ester to cure Curable organopolysiloxane composition (here, As the condensation reaction,
Dehydration reaction, dealcoholization reaction, deoxime reaction, deamine reaction, deamidation reaction, decarboxylic acid reaction, deketone reaction, etc.) can be exemplified); Examples of the siloxane composition include a high energy ray-curable organopolysiloxane composition which is cured by γ-ray, ultraviolet ray or electron irradiation.

Among these curable organopolysiloxane compositions, the addition reaction-curable organopolysiloxane composition described above serves as the main component of the desired organopolysiloxane elastomer spherical powder and has a curing rate higher than that of the other compositions. The curable organopolysiloxane composition can be exemplified as a preferable curable organopolysiloxane composition which is fast and has excellent curing uniformity.

Further, particularly preferable ones as the addition reaction-curable organopolysiloxane composition are:
(A) Organopolysiloxane having at least two lower alkenyl groups in one molecule, (B) Organopolysiloxane having at least two silicon-bonded hydrogen atoms in one molecule, and (C) Platinum-based catalyst It is an addition reaction-curable organopolysiloxane composition.

The silicon atoms of the organopolysiloxanes contained in the above-mentioned curable organopolysiloxane compositions 1 to 3 can simultaneously bond with other organic groups other than the above groups. As such other organic group,
For example, alkyl groups such as methyl group, ethyl group, propyl group, butyl group and octyl group; 2-phenylethyl group, 2-
Substituted monovalent carbonization having phenylpropyl group, substituted alkyl group such as 3,3,3-trifluoropropyl group; aryl group such as phenyl group, tolyl group, xylyl group; epoxy group, carboxylic acid ester group, mercapto group, etc. A hydrogen group etc. can be mentioned.

A desired organopolysiloxane elastomer spherical powder can be obtained by applying a method corresponding to the properties of the above-mentioned curable organopolysiloxane compositions 1 to 3 thus prepared.
That is, when the addition reaction-curable organopolysiloxane composition, condensation reaction-type organopolysiloxane composition or peroxide-curable organopolysiloxane composition is selected as the main component of the organopolysiloxane elastomer spherical powder, The curable organopolysiloxane composition is mixed with water in the presence of a surface active agent such as a nonionic surface active agent, an anionic surface active agent, a cationic surface active agent or an amphoteric surface active agent, which is then mixed with a homomixer or a colloid mill. , A homogenizer, a propeller-type mixer, etc. are used for uniform mixing, and this mixture is discharged into hot water at 50 ° C. or higher to obtain the desired organopolysiloxane elastomer spherical powder.

Further, when the curable organopolysiloxane composition (1) is selected as the main agent, these organopolysiloxane compositions are directly sprayed in a hot air stream to be cured to obtain a desired organopolysiloxane elastomer spherical powder. It is also possible to adopt a method of obtaining.

When a high energy ray-curable organopolysiloxane composition is selected as the main agent, this organopolysiloxane composition is sprayed and cured under irradiation with high energy rays to give a desired organopolysiloxane elastomer spherical shape. It is also possible to adopt a method of obtaining powder. Thus, the organopolysiloxane elastomer spherical powder having an average particle diameter of 1.0 μm or more and 15.0 μm or less, which is mixed in the makeup cosmetic of the present invention, can be obtained.

The details of the method of producing these organopolysiloxane elastomer spherical powders are described in JP-B-4-66446, JP-A-2-243612 and JP-B-4-17162. .

In the present invention, it is also possible to use a commercially available product of the above organopolysiloxane elastomer spherical powder. Specifically, for example, Trefil E-50
5C, Trefil E-506C (manufactured by Toray Dow Corning Silicone Co., Ltd.) and the like can also be used.

The blending amount of the above-mentioned organopolysiloxane elastomer spherical powder in the makeup cosmetic of the present invention should be specifically determined depending on the specific form of the cosmetic and the extent to which the makeup retention is improved. Although not particularly limited, it is generally blended in the range of 0.1% by weight or more and 80% by weight or less with respect to the entire cosmetic.

If the blending amount is less than 0.1% by weight based on the total amount of the cosmetic, it is not preferable because improvement of makeup retention cannot be sufficiently achieved. On the other hand, if the blending amount exceeds 80% by weight with respect to the total amount of the cosmetic, the adhesiveness of the resulting makeup cosmetic to the skin tends to be poor, which is not preferable for use.

The above-mentioned organopolysiloxane elastomer spherical powder can be preferably blended in the makeup cosmetic of the present invention in the range of 0.1% by weight or more and 30% by weight or less based on the total amount of the cosmetic.

The make-up cosmetics containing the above-mentioned organopolysiloxane elastomer spherical powder in the preferred blending range, of course, have a good makeup lasting property, and by the action of the organopolysiloxane elastomer spherical powder itself, spread smoothly. Is lighter and has good usability.

C. The average particle size is 1.0 μm or more, 15.
The blending balance of the organopolysiloxane elastomer spherical powder having a particle size of 0 μm or less and the active zinc white in the makeup cosmetic of the present invention is not particularly limited as long as both are within the above-mentioned blending range. However, when the amount of the other component is extremely smaller than that of the other component, the properties inherent in the one component (described above) tend to be more positively exerted in the present invention.

As a general rule, it is not necessary to consider the mixing balance between the two when the mixing components of both are in the above-mentioned preferable mixing ranges. Thus, the specific blending balance should be individually determined depending on the specific form of the makeup cosmetic of the present invention, the extent to which the makeup lasting is improved, and the like.

In this way, by blending the organopolysiloxane elastomer spherical powder of 15.0 μm or less and the active zinc white in the makeup cosmetic composition, the two components act synergistically in terms of keeping the makeup. That is, the makeup cosmetic of the present invention, which is extremely excellent in the desired makeup retention, is provided.

D. In the makeup cosmetic of the present invention, by exhibiting the above-mentioned intended effects of the present invention, by mixing the above-mentioned both components with a base component or a colorant according to the makeup cosmetic of a desired form. As long as it is a makeup cosmetic that is intended only for this intended effect, it is not particularly necessary to additionally mix other ingredients that are positively involved in improving the makeup lasting.

However, for the purpose of imparting the effect that makeup cosmetics will generally have by adding other components, it is necessary to add other components so that the desired effect of the present invention can be obtained. It is possible within a range that does not impair
