Description

  The present invention relates to a solid powder cosmetic, and more particularly to a solid powder cosmetic excellent in glitter on the coated surface and having sufficient impact resistance.

  In recent years, for eye shadows and cheek colors, cosmetics having a brilliant finish are demanded. In order to obtain such a brilliant finish, it is necessary to add a large amount of glitter powder such as a pearl agent or a lame agent. However, pearls and glitters have poor moldability, and impact resistance decreases significantly when blended in cosmetics in large quantities, so the impact resistance of solid powder cosmetics blended in large quantities of pearls and glitters is improved. It is being considered.

As a method of blending a large amount of a pearl agent or a lame agent while ensuring sufficient impact resistance, a method of blending a combination of 60% by mass or more of a pearl agent with liquid oil and solid oil having a specific polarity (Patent Document 1 ), 50-80% by mass of glitter powder and talc having a specific disintegration coefficient in combination with 1/10 to 6/10 parts by mass of the glitter powder (Patent Document 2), 70% by mass or more (Patent Document 3) and the like have been proposed in which a plate-like powder (pearl agent) is combined with flaky silicic anhydride and hydrocarbon wax powder.

  However, it is difficult to give sufficient impact resistance by any of the above methods, and solid powder cosmetics containing a large amount of glitter powder and solid oil or wax powder at the same time can be used at the time of use. There is a possibility of causing caking. When a large amount of glittering powder and a certain amount or more of talc are blended, not only does the spread of the coating worsen, but the coated surface becomes a mat and a large amount is blended. The texture of the pearl agent could not be utilized. Therefore, it contains a large amount of pearl and lame agents, has a brilliant finish, does not cause quality problems such as caking, spreads well during application, and has excellent impact resistance. Development of solid powder cosmetics has been desired.

  As a result of intensive studies in view of the above circumstances, the present inventor has obtained a solid powder makeup obtained by mixing a cosmetic base material and a volatile solvent, filling the container, and then removing the volatile solvent. Solid powder with excellent glitter feeling such as pearly feeling and glitter feeling while having impact resistance sufficient for use by blending a certain amount or more of glitter pigment and a certain amount of fatty acid aluminum salt We found that cosmetics can be obtained.

That is, the present invention provides a solid powder cosmetic obtained by mixing a cosmetic base material and a volatile solvent, filling the container, and then removing the volatile solvent.
(A) 50 to 90% by weight of glittering powder with respect to the cosmetic base material (b) 0.1 to 5% by weight of fatty acid aluminum salt with respect to the cosmetic base material as an essential component,
(C) A solid powder cosmetic characterized by using light liquid isoparaffin and / or isododecane as a volatile solvent used for mixing with a cosmetic base material.
