Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is easy to apply to the skin, has a soft and smooth feel, does not impose a burden on the skin, and makes spots, wrinkles, bruises, etc. less noticeable and beautiful. The present invention relates to an excellent powder solid cosmetic having a finishing effect.

[0002]

2. Description of the Related Art Conventional powder solid cosmetics have an oil content of about 10-.
Most of them are about 25% by weight, and they have a drawback that they do not have a soft feel and are hard to blur on the skin. Also, there are some solid oils such as white powder and blusher which have an oil content of less than 10% by weight, but these do not have a soft feel because they contain a large amount of talc as a powder component.

[0003]

SUMMARY OF THE INVENTION In view of such circumstances, the present inventors have a tendency to easily apply to the skin, have a soft and smooth feel, do not impose a burden on the skin, and stain, wrinkle,
As a result of diligent research to develop a powder solid cosmetic that makes bruise and the like inconspicuous and enables a strange finish, spherical powder 15-30% by weight, plate powder 40-70% by weight, oil content 9% by weight % And / or 10% by weight or less of the powdered excipient is found to solve the above problems, and the present invention has been completed.

[0004]

Means for Solving the Problems That is, the present invention provides (1) 15-30% by weight of spherical powder and 40-70 of plate-like powder.
Wt%, oil content 9 wt% or less, and / or powder solid-type cosmetics containing 10 wt% or less of powder excipient (2) The spherical powder is a spherical resin powder having an average particle diameter of 3 to 20 μ. Powder solid cosmetic (3) The powder according to (1) or (2), wherein the plate-like powder is one or more selected from the group consisting of sericite, mica, synthetic mica, calcined sericite and calcined mica. Regarding solid cosmetics.

The structure of the present invention will be described in detail below. In the present invention, a spherical solid powder and a plate-like powder are used as a basic combination, and a small amount of an oil component and / or a powder excipient is mixed as a binder into a powder solid cosmetic.

The spherical powder used in the present invention includes all the general spherical powders used in the art, but particularly spherical resin powders such as nylon powder, polyacrylonitrile powder, polyester powder,
Examples thereof include polystyrene powder, polypropylene powder, polyethylene powder, tetrafluoroethylene powder, polymethylmethacrylate powder, silicon powder, and cellulose powder, and these may be used alone or in combination of two or more.

The amount of the spherical powder compounded is 15 to 30% by weight, preferably 15 to 25% by weight, based on the total amount of the powder solid cosmetic.
Is. If the content of the spherical powder is less than 15% by weight or more than 30% by weight, a soft and smooth feeling cannot be obtained, and if it is more than 30% by weight, impact resistance becomes poor. The average particle size of the spherical powder is 3-20μ, preferably 3-15μ, and more preferably 3-10μ.

The plate-like powder used in the present invention includes one or more kinds of sericite, mica, synthetic mica, calcined sericite, calcined mica and the like, and the compounding amount thereof is 40-70% by weight. But preferably 45-65% by weight
Is. When the amount of the plate-like powder is less than 40% by weight, a soft and smooth feel cannot be obtained, and when the amount is more than 70% by weight, it becomes powdery, so a soft and smooth feel cannot be obtained and the impact resistance is high. It becomes inferior in sex. And
The use of the plate-like powder surface-treated with silicone, fluorine or the like has the advantages that the makeup lasting is improved and water can be used, and the application range of the present invention is further broadened.
