Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a solid powder cosmetic containing a calcined mica, a hydrocarbon wax powder, and titanium oxide-encapsulated silica,
More specifically, it has excellent spreadability during application and gloss of the cosmetic film, and the cosmetic film does not dull over time and caking (a phenomenon that the solid powder cosmetic surface becomes hard when repeatedly used) does not occur, and moldability is improved. The present invention relates to a solid powder cosmetic having excellent (impact resistance).

[0002]

BACKGROUND OF THE INVENTION Solid powder cosmetics are a type of cosmetics used for a wide variety of cosmetics such as white powder, foundation, blusher, and eye color because of their excellent portability and ease of use. However, a cosmetic film made of a solid powder cosmetic is mainly a powder film, and the finished cosmetic film is often powdery and has a matte finish (matte finish). Therefore, in order to suppress the powdery finish and enhance the gloss of the cosmetic film, a plate-like powder such as natural mica is blended. However, when a large amount of plate-like powder such as natural mica is blended, the moldability is deteriorated, and there are problems that the solid powder cosmetic is cracked or cracked when dropped or carried. In addition, the addition of natural mica enhances the glossiness of the finished product, but it sometimes becomes wet with sebum and the like secreted from the skin to reduce the lightness and cause dullness of the cosmetic film.

[0003]

Therefore, as a technique for improving the moldability, a method of increasing the amount of the blended oil agent, a method of increasing the compounding amount of powder having good moldability such as talc, etc. have been used. However, in the method of increasing the amount of the blended oil agent, caking may occur at the time of use, and in the method of incorporating a large amount of talc, the spread and spread at the time of application may not be good and the finished cosmetic film may become a mat. It was
Further, in order to suppress dullness of the cosmetic film, a method of blending synthetic mica obtained by removing impurities such as iron from natural mica was used, but according to this method, the powder became wet with sebum and the like over time. Although the decrease in brightness was suppressed to some extent, it was not at a level that was fully satisfactory. Therefore, the spreadability at the time of application and the glossiness of the cosmetic film are excellent, the cosmetic film does not dull over time, and the change in brightness can be reduced even if the cosmetic film gets wet with sebum,
It has been desired to develop a solid powder cosmetic having excellent moldability (impact resistance) without causing caking.

[0004]

In view of the above circumstances, the inventors of the present invention have made earnest studies, and as a result, have solved the above problems by containing calcined mica, hydrocarbon wax powder and titanium oxide-encapsulating silica. The inventors have found that a solid powder cosmetic can be obtained and completed the present invention. That is, the present invention is
