Description

Solid powder cosmetic

The present invention relates to a solid powder cosmetic.

Solid powder cosmetics are widely used as foundation cosmetics such as foundation cosmetics such as foundation, white powder, eye color, teak color, eyebrows, body powder, whitening powder, etc. from the convenience of portability and ease of use. ing. Further, in recent years, in order to achieve an ultraviolet protective ability improvement and a clear feeling without white film, a technique using a fine particle metal oxide has been studied (see, for example, Patent Document 1).

As a method for producing a solid powder cosmetic, a dry molding method in which powder and oil are mixed and then press molding, and a cosmetic base comprising powder and oil and the like are added with a solvent to form a slurry and filled in a container. After that, a wet molding method for obtaining a cosmetic by removing the solvent is well known. The solid powder cosmetic obtained by the wet molding method can be filled in containers of various shapes because it is filled in a fluid slurry state, and a cosmetic with high aesthetics can be obtained. On the other hand, in the case of the wet molding method, the filling moldability may be a problem, and various studies have been made. For example, in order to improve the filling and molding properties, techniques using film-forming polymers (see, for example, Patent Document 2), techniques using spherical polyolefin resin powder and non-volatile oil agent (see, for example, Patent Document 3) are known. It is done.

However, when a solid powder cosmetic is produced using the technique of Patent Document 1 in order to obtain a cosmetic excellent in UV protection ability and transparency, the squeakiness due to the strength of the cohesive force of the particulate metal oxide In addition, the smoothness of the molding surface could not be obtained.

In addition, when a solid powder cosmetic containing fine particle metal oxides is produced by a wet molding method, the removal efficiency of the solvent may decrease due to the size of the surface area, which may cause shrinkage of the molded product. The Even when the technique of Patent Document 1 is used, the squeakiness due to the particulate metal oxide and the shrinkage of the molded product can not be suppressed, and furthermore, the polymer forms a film on the surface of the molded product, which is satisfactory. In some cases, the smoothness of the surface of the molded article could not be obtained. Similarly, even when the technique of Patent Document 2 is used, the squeakiness due to the fine particle metal oxide and the shrinkage of the molded product can not be suppressed, and the impact resistance may also be poor.

Therefore, the main object of the present invention is to provide a solid powder cosmetic which is excellent in transparency, not squeaky, and excellent in the smoothness of the surface of a molded product but has no shrinkage of the molded product and is excellent in impact resistance. I assume.

In view of such circumstances, as a result of intensive studies conducted by the present inventor, in cosmetics containing fine particle metal oxides (preferably metal oxides having an average particle diameter of 0.01 to 0.1 μm) By containing 30% by mass of silicone oil, compared with the case where hydrocarbons, ester oil, etc. are contained, it is excellent in transparency and smooth on the surface of a molded product, but it is a solvent at the time of filling and molding. It has been found that the removal efficiency is improved and the shrinkage of the molded product after drying can be suppressed. Furthermore, the present inventor revealed that the inclusion of the particulate metal oxide and the silicone oil in the solid powder cosmetic does not have sufficient squeakiness and impact resistance required for the solid powder cosmetic. .

Therefore, as a result of intensive research conducted by the present inventor, the present inventors reduce the squeakiness of the particulate metal oxide by containing the amino-modified silicone-treated powder having a cationic group, and further, the silicone oil is added to the specific amount.

On the other hand, Comparative Example 1 in which a large amount of titanium oxide (No. 2) having an average particle diameter of 0.25 μm of component (F) was used instead of component (A) was a film whiteness derived from its optical characteristics. Caused a loss of transparency. The comparative examples 2 and 3 which do not contain a component (B) were not able to suppress the squeaky feeling originating in fine particle metal oxide, and were inferior in the smoothness and impact resistance of the molding surface. Comparative Example 4 using an ester oil instead of the component (C) is extremely inferior in smoothness of the surface of the molded product, non-shrinkage of the molded product, and impact resistance due to the influence of high bond strength with the powder. It was a thing. Further, in Comparative Example 5 in which a large amount of the component (C) is compounded, the removal efficiency of the solvent is deteriorated due to the progress of the wetting of the powder with the oil agent, and the shrinkage of the molded product and the resultant decrease in impact resistance occur. became.

From this, in order to obtain a solid powder cosmetic which is excellent in transparency, not squeaky, and excellent in the smoothness of the surface of the molded product but has no shrinkage of the molded product and is excellent in impact resistance, (A) It was considered important to use particulate metal oxides, (B) amino modified silicone treated powder, (C) silicone oil.
Furthermore, in order to obtain a more remarkable effect, partially cross-linked organopolysiloxane polymer as component (D), (fluorination / hydroxylation / oxidation) / (Mg / K / silicon) as component (E), component (D) As F), it was thought that it would be preferable to further use one or more selected from large particle size metal oxides and boron nitride as component (G) for the solid powder cosmetic. Moreover, in order to obtain a more remarkable effect, it is preferable to contain phenyl modified silicone in the said component (C) silicone oil, and the content mass ratio in phenyl modified silicone / component (C) silicone oil is suitably Was considered to be 0.3 or more, more preferably 0.3 to 0.9.
Moreover, in order to obtain a more remarkable effect, the content mass ratio of the said component (A) and the said component (C) is (C) / (A) = 0.6-15 as a mass ratio at the time of mix | blending a component. And / or that the content mass ratio of the component (C) in the total oil agent is component (C) / totally blended oil agent = 0.6 to 1.0. .
