Description
Technical Field
The present invention relates to a solid powder cosmetic.
Background
Solid powder cosmetics have been widely used as base cosmetics such as makeup cosmetics including foundation, face powder, eye shadow, cheek color, eyebrow pencil, etc., body powder, whitening powder, etc., because of convenience in carrying and easiness in use. In recent years, a technique using a fine particle metal oxide has been studied in order to improve ultraviolet protection ability and achieve a cosmetic feel with a transparent feel without a white film feel (see, for example, patent document 1).
As a method for producing a solid powder cosmetic, there are known: a dry molding method in which powder and oil are mixed and then pressure-molded; and a wet molding method in which a solvent is added to a cosmetic base material comprising a powder, an oil agent, and the like to form a slurry, the slurry is filled into a container, and then the solvent is removed to obtain a cosmetic. Since the solid powder cosmetic obtained by the wet molding method is filled in a slurry state having fluidity, it can be filled in containers of various shapes, and a cosmetic with high aesthetic quality can be obtained. On the other hand, the wet molding method sometimes has a problem in filling moldability, and various studies have been made. For example, in order to improve the filling moldability, a technique of forming a polymer using a coating film (for example, see patent document 2), a technique of using a spherical polyolefin resin powder and a nonvolatile oil agent (for example, see patent document 3), and the like are known.

Disclosure of Invention
Problems to be solved by the invention
However, in order to obtain a cosmetic excellent in ultraviolet protection ability and transparency, when a solid powder cosmetic is produced by the technique of patent document 1, a feeling of astringency is caused by a strong cohesive force of the fine particle metal oxide, and further, smoothness of the surface of the molded product cannot be obtained.
In addition, when a solid powder cosmetic containing a fine-particle metal oxide is produced by a wet molding method, the solvent removal efficiency may be reduced due to a large surface area, and the molded product may shrink. On the other hand, even when the technique of patent document 1 is used, the astringency caused by the fine-particle metal oxide and the shrinkage of the molded product cannot be suppressed, and further, the polymer forms a film on the surface of the molded product, and therefore satisfactory smoothness of the surface of the molded product cannot be obtained in some cases. Similarly, even when the technique of patent document 2 is used, the feeling of astringency due to the fine-particle metal oxide and the shrinkage of the molded article cannot be suppressed, and the impact resistance is sometimes poor.
Accordingly, a main object of the present invention is to provide a solid powder cosmetic which is excellent in transparency, free from a feeling of astringency, excellent in smoothness of the surface of a molded article, free from shrinkage of the molded article, and excellent in impact resistance.
Means for solving the problems
As a result of intensive studies in view of such circumstances, the present inventors have found that by containing 4 to 30 mass% of a silicone oil in a cosmetic containing a fine-particle metal oxide (preferably a metal oxide having an average particle diameter of 0.01 to 0.1 μm), the cosmetic is excellent in transparency and smoothness of the surface of a molded article, and further, the removal efficiency of a solvent during filling molding is improved and the shrinkage of the molded article after drying can be suppressed, as compared with the case where the cosmetic contains a hydrocarbon, ester oil or the like. Further, the present inventors have found that only by incorporating a fine-particle metal oxide and a silicone oil into a solid powder cosmetic, the solid powder cosmetic is required to have no harsh feeling and insufficient impact resistance.
The present inventors have further conducted extensive studies and as a result have found that the inclusion of an amino-modified silicone-treated powder having a cationic group can reduce the astringent feeling of the fine-particle metal oxide and further improve the reduction in impact resistance caused by the inclusion of the specific amount of the silicone oil.
From the above-described circumstances, the present inventors have found that a solid powder cosmetic excellent in transparency, free from a feeling of astringency, excellent in smoothness of the surface of a molded article, free from shrinkage of the molded article and excellent in impact resistance can be obtained by using (a) a fine-particle metal oxide, (B) an amino-modified silicone-treated powder and (C) a specific amount of a silicone oil. Thus, the present inventors have completed the present invention.
That is, the present invention provides a solid powder cosmetic comprising the following components (a) to (C):
(A) the metal oxide particles are in the form of fine particles,
(B) the amino-modified organic silicon is used for treating powder,
(C) 4-30% by mass of silicone oil.
The component (A) may be 1 or 2 or more selected from titanium oxide and zinc oxide.
The mass ratio of the component (a) to the component (C) may be 0.6 to 15 (C)/(a).
Further, a partially crosslinked organopolysiloxane polymer may be contained as component (D).
Further, it may contain (fluorination/oxidation)/(Mg/K/silicon) as the component (E).
Further, a metal oxide having a particle diameter larger than that of the component (A) may be contained as the component (F).
Further, it may contain 2 to 7 mass% of boron nitride as the component (G).
The component (C) may contain a phenyl-modified silicone.
The mass ratio of the component (C) in the total oil may be 0.3 to 1.0 in terms of component (C)/total blended oil.
In addition, the present invention can also provide a solid powder cosmetic obtained by: the following components (A) to (C) were used as cosmetic base materials,
(A) the metal oxide particles are in the form of fine particles,
(B) the amino-modified organic silicon is used for treating powder,
(C) 4 to 30 mass% of silicone oil,
mixing the above (a) to (C) with a solvent to form a slurry, filling the slurry into a container, and removing the solvent.

The method for producing a solid powdery cosmetic of the present invention is preferably a compression molding method including a step of mixing a powder and an oil agent.
In addition, as the method for producing the solid powdery cosmetic of the present invention, a wet molding method is preferably used, and more specifically, a wet molding method including a step of mixing a powder, an oil agent, and a solvent is more preferably used. For example, a cosmetic base containing a powder and an oil agent may be prepared in advance, and then the cosmetic base is mixed with the oil agent to obtain the solid powder cosmetic of the present invention. For the solid powdery cosmetic of the present invention, a solvent and a cosmetic base (for example, a powder, an oil agent and the like) may be mixed to obtain the solid powdery cosmetic of the present invention, and the powder, the oil agent and the like may be mixed with the oil agent simultaneously or separately.

Of these, from the viewpoint of excellent dispersibility of the cosmetic base material, 1 kind or a combination of 2 or more kinds of low boiling hydrocarbon oils such as isododecane, isohexadecane, and light mobile isoparaffin is more preferably used.
The amount of the solvent to be mixed in the wet molding method is arbitrarily selected to give fluidity to the mixture before molding by filling the mixture into a container or a medium dish, but from the viewpoint of ease of solvent removal efficiency, it is more preferable to use 10 to 150 parts by mass of the solvent per 100 parts by mass of the cosmetic base material (hereinafter, also simply referred to as "parts"). The solvent may be removed by drying as it is, or by filling the slurry and then pressurizing to remove the volatile solvent (solvent) through an absorber or a vent.

It should be noted that (evaluation method: high or low transparency, no harsh feeling, and smoothness of molded product surface), it is judged that any of the "no or no" determinations is difficult to be made as the "evaluation criterion >" normal 3 point ", and if the whole team judges as" normal 3 point ", the average point of the total score becomes the" 4-grade judgment criterion > "3.0 point" and the "△ (slightly poor)" evaluation criterion, and it is necessary to obtain the "evaluation criterion >" good: 4 point "or more in order to obtain the" 4-grade judgment criterion > "○ (good)" evaluation criterion.
The average molecular weight of the silicone oil is preferably 500 to 15000.
As is clear from the results in Table 1, examples 1 to 15 and 19 to 23 are cosmetics excellent in transparency, free from harsh feeling, excellent in smoothness of the surface of the molded article, free from shrinkage of the molded article, and excellent in impact resistance.
On the other hand, in comparative example 1 in which a large amount of titanium oxide (No.2) having an average particle size of 0.25 μm was used alone in place of the component (A), the transparency was impaired due to whitening caused by the optical characteristics. In comparative examples 2 and 3 containing no component (B), the feeling of astringency derived from the fine-particle metal oxide could not be suppressed, and the surface smoothness and impact resistance of the molded article were also poor. In comparative example 4 using ester oil instead of component (C), the smoothness of the surface of the molded article, the non-shrinkage property of the molded article, and the impact resistance were significantly deteriorated due to the high bonding force with the powder. In comparative example 5 in which a large amount of component (C) was blended, wetting of the powder with the oil agent occurred, which resulted in poor solvent removal efficiency, and as a result, shrinkage of the molded article and a concomitant decrease in impact resistance occurred.
From this fact, it is considered that the use of (a) a fine-particle metal oxide, (B) an amino-modified silicone-treated powder, and (C) a silicone oil is important in order to obtain a solid powder cosmetic which is excellent in transparency, free from a feeling of astringency, excellent in smoothness of the surface of a molded article, free from shrinkage of the molded article, and excellent in impact resistance.
Further, in order to obtain more remarkable effects, it is preferable to further use 1 or 2 or more selected from the group consisting of a partially crosslinked organopolysiloxane polymer as the component (D), a (fluorinated/hydro-oxidized/oxidized)/(Mg/K/silicon) as the component (E), a metal oxide having a large particle size as the component (F), and boron nitride as the component (G) in the solid powder cosmetic. In order to obtain a more significant effect, it is also considered that the phenyl-modified silicone is preferably contained in the silicone oil as the component (C), and the content mass ratio of the phenyl-modified silicone to the silicone oil as the component (C) is preferably 0.3 or more, and more preferably 0.3 to 0.9.
In order to obtain more remarkable effects, it is preferable that the mass ratio of the component (a) to the component (C) be 0.6 to 15, and/or the mass ratio of the component (C) in the entire oil agent be 0.6 to 1.0, in terms of the component (C)/the entire oil agent.
In examples 19 to 23, TAROX R-516P, TAROX YP1200P and TAROX BL-100P were used as the iron oxide red, the iron oxide yellow and the iron oxide black, respectively.
