Description

TECHNICAL FIELD The present invention relates to a solid powder cosmetic that is excellent in color dullness over time, uniformity of the cosmetic film, long-lasting effect against perspiration, sebum and movement, and powder glossiness.

Solid powder cosmetics such as eye shadow and powder foundation are mainly composed of powder, mixed with appropriate pigments and oils, and are widely used by consumers because they are easy to use and have excellent portability. Supported. However, powder is composed of inorganic compounds and organic compounds, and is easily absorbed by sweat and sebum. There was a problem of color dullness, where the powder gets wet and the brightness decreases and the original color tone is lost. In solid powder cosmetics, it is difficult to evenly disperse an oil agent, etc., and the aggregation of the oil agent impairs the orientation of the plate-like powder to the cosmetic film, which impairs the glossiness of the powder. Agglomeration sometimes resulted in non-uniform cosmetic film.

In order to solve such problems, for example, as in Patent Document 1, powder is formed into a solid shape by containing a specific silicone polymer, a fluorine-based compound surface coating treatment powder, and a fluoroalkyl group-containing organopolysiloxane. Attempts have been made to provide a powdery solid cosmetic that has good moldability when applied, has a smooth and refreshing feel, is excellent in usability, is rich in water repellency and oil repellency, and has a long lasting makeup.

In addition, for example, as in Patent Document 2, a powder surface-treated with a silane compound having an amino group, a titanium compound, or a polysiloxane compound and a compound having a fluoroalkyl group is blended to provide a feeling of use, especially adhesion to the skin. Attempts have been made to provide a powder for cosmetics that is excellent in moist feeling, does not easily cause makeup to come off, and has good usability as a powder.

In addition, as in Patent Document 3, for example, by containing an amino-modified silicone-treated powder and an ester oil containing a hydroxyl group, the cosmetic has excellent longevity, is easy to remove, spreads when applied, and does not form a film. Attempts have also been made to provide a solid powder cosmetic which is excellent in uniformity and has good color development in a cosmetic film after application.

Further, as in Patent Document 4, for example, an attempt has been made to provide a solid powder cosmetic that contains titanium dioxide-coated mica and an adhesive oil agent, thereby providing gloss and make-up effects such as a color rendering effect and excellent usability. ing.

However, as in Patent Document 1, when fluorine-based compound-coated powder and fluoroalkyl group-containing organopolysiloxane are used, the affinity with the skin is low, and sweat and sebum inside the cosmetic film may cause the makeup to break down. In some cases, the film was whitened, the durability of the makeup was lowered, and the glossiness of the powder was impaired due to the whitening.

In addition, as in Patent Document 2, when using a powder surface-treated simultaneously with a specific compound having an amino group and a compound having a fluoroalkyl group, by imparting a hydrophilic amino group, The water repellency of the powder was not sufficiently exhibited, and when sweating, the powder was wetted by sweat, etc., and dullness was observed in some cases. Compounds with fluoroalkyl groups and amino groups have low compatibility, and the surface-treated powder used in combination may be surface-treated in a state in which the highly hydrophilic amino group-containing compound and fluoroalkyl groups are each localized. As a result, non-uniform surface treatment may occur, causing cohesion between powders and impairing the uniformity of the cosmetic film.

When the amino-modified silicone-treated powder of Patent Document 3 and an ester oil containing a hydroxyl group are used, the amino-modified silicone-treated powder has insufficient water repellency, and in addition, the ester oil containing a hydroxyl group having high polarity is used. is used, the water resistance is weak, and there are cases where the make-up lasts due to perspiration or the like.

Cosmetics containing titanium oxide-coated mica and tacky oil agents, such as those disclosed in Patent Document 4, are excellent in powder luster, but use viscous oil agents, and the oil agents are uniformly dispersed in the powder. The uniformity of the cosmetic film may be impaired, and the cohesion of the oil that enhances the bonding force between the skin and the powder reduces the adhesion of the powder to the skin and prevents movement. There was a case where the makeup film was easily collapsed and the makeup lasting was deteriorated.
As described above, there is a demand for a solid powder cosmetic that is free from dullness, has a uniform cosmetic film, is highly durable against perspiration, sebum and movement, and has excellent powder gloss.

In view of such circumstances, the present inventors have made intensive studies, and as a result, have produced a powder whose surface is coated with a specific both-terminally reactive diorganopolysiloxane and a specific amino group-containing silane compound, and used it as a solid powder cosmetic. It was discovered that it has excellent adhesion to the skin and imparts a long-lasting effect on movement when applied, and trifluoropropylcyclopolysiloxane imparts a water- and oil-repellent effect without breaking the coating film. It has been found that it imparts long-lasting makeup effect and no color dullness against sweat and sebum over time. Further, the inventors have found that the uniformity of the cosmetic film and the luster of the surface-treated powder can be imparted by uniformly dispersing it in the surface-treated powder. In addition, by containing a partially crosslinked fluorine-modified organopolysiloxane polymer, trifluoropropylcyclopolysiloxane has an appropriate viscosity, preventing sedimentation of the oil when dispersing it in the powder, and The dispersibility of the solid powder cosmetic is further enhanced, the color does not become dull over time, the uniformity of the cosmetic film, the makeup durability against sweat, sebum, and movement, and the glossiness of the powder are also obtained. was completed.
