Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powdery cosmetic having a powdery form in which hydrophobic powder is oriented and uniformly coated on the surface of a water-drop-shaped aqueous component. More specifically, it does not have a squeaky feeling, is excellent in freshness and refreshing feeling, and even if it is rubbed directly on the skin with a finger or a hand, it can be applied smoothly without scratches and rubs and has excellent even application properties. , Especially when mixed with pearlescent agents and lame agents, it is possible to exert high transparency without impairing the texture (pearlescent feeling / lamellar feeling), color feeling, and color tone that they have, and a very good makeup finish. The present invention relates to a powdery cosmetic having an effect.

[0002]

2. Description of the Related Art Conventionally, powdery cosmetics, so-called dry water, are liquefied by coating a water-soluble component such as water or a water-soluble component with a powder which has been subjected to a hydrophobic treatment to form a powder and rubbing it at the time of use. It is designed to do. Various powder cosmetics such as whitening powder (powder whitening lotion) and skin care products are known.
A large amount of an aqueous component exceeding 0 to 90% by mass is coated with a hydrophobic powder to form a powder. When such a pearlescent agent / lamellar agent is added to the powdery cosmetic material containing a large amount of the contained aqueous component for the purpose of imparting a makeup effect, the pearlescent agent / lamellar agent cannot be uniformly applied on the skin. There is a phenomenon, especially when applied directly on the skin with fingers or hands,
It is easy to cause unevenness or partial discoloration, and it is difficult to apply it effectively and evenly on the skin as a makeup cosmetic.

By the way, makeup cosmetics such as eye shadows and face colors have various shapes such as rod-shaped, stick-shaped, powder-solidified, etc., but are usually coloring materials, extender pigments, pearlescent agents and lame agents. In addition to powder components such as, the oil content as a binder is blended. In such conventional makeup cosmetics, due to the influence of oil content and other components (extensive pigments, etc.), the color and texture (pearly / lame) originally possessed by the coloring material and pearlescent agent / lame agent are imparted. It is difficult to produce a makeup effect without loss,
The transparency was low, the color tone was low, and the color tended to be dark and turbid. Therefore, in order to suppress such a problem, it is necessary to mix these coloring materials and pearlescent agents / lamellar agents in the cosmetics in an amount of 40 to 50% by mass or more.

[0004]

DISCLOSURE OF THE INVENTION The present invention is intended to solve the above-mentioned conventional problems, and has no squeaky feeling, is excellent in freshness and refreshing feeling, and is directly rubbed on the skin with fingers or hands. Even if it is mixed with pearlescent agents and lame agents, it does not deteriorate the texture (pearly feeling or lame feeling), color feeling, color tone, etc. An object of the present invention is to provide a powdery cosmetic which can be highly transparent and has an extremely excellent makeup finishing effect.

[0005]
