Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid powder cosmetic having a wet appearance with a dry and light feeling of use.

[0002]

2. Description of the Related Art In recent years, solid powder cosmetics are required to have smoothness, light spreadability, and long-lasting makeup in addition to the function of adjusting skin color. Conventional solid powder cosmetics have refreshing usability, and have been blended with high-viscosity dimethylpolysiloxane in order to improve fit and hold.

[0003]

However, solid powder cosmetics containing high-viscosity dimethylpolysiloxane have the following problems.
Although it is not sticky and has a smooth usability, it has a drawback that the wetting with powder is poor and the appearance color becomes whitish with respect to the coating color. Conventionally, if the amount of high-viscosity dimethylpolysiloxane is increased to increase the appearance color,
There was a tendency for cakes to become heavy and to be difficult to remove.

[0004]

[Means for Solving the Problems] The present inventors provide a solid powder cosmetic having a wet appearance color while having a light spreadability, a smooth useability and a good makeup retention. As a result of intensive studies for the purpose of the above, it was found that this problem can be solved by using dimethylpolysiloxane and a hydrocarbon wax in combination, and the present invention has been completed.

That is, the present invention is a solid powder cosmetic containing a high-viscosity dimethylpolysiloxane and a hydrocarbon wax.

The structure of the present invention will be described below. The high-viscosity dimethylpolysiloxane used in the present invention is represented by the following general formula (1).

[0007]

[Chemical 1]

The high-viscosity dimethylpolysiloxane of the above-mentioned general formula (1) used is usually classified by viscosity and is generally about 1000 to 10000 cs.
000 to 8000 cs is preferably used. 10
When it is 00 cs or less, the effect of the present invention cannot be exhibited, and when it is 10000 or more, usability tends to deteriorate.

The blending amount is 1.0% by weight to 20% by weight, preferably 2.0% by weight to 15.0% by weight. If the blending amount is less than 1.0%, a dry feel and good makeup retention cannot be obtained, and if the blending amount exceeds 20.0% by weight, peeling is deteriorated and caking or spreadability is deteriorated. Tend to pull the surface of the skin and make it unusable.

The hydrocarbon wax used in the present invention includes olefin compounds such as ceresin, microcrystalline wax, solid paraffin and polyethylene wax. Of these, ceresin is the most preferable in terms of non-stickiness. The blending amount of the hydrocarbon wax is preferably 0.1% by weight or more and 4% by weight or less. If the blending amount is less than 0.1% by weight, the appearance color is whitish and the effect of the present invention is not obtained, and if it exceeds 4% by weight, the meltability becomes poor and a caking phenomenon occurs, which is not preferable.

In addition to the above-mentioned essential components, the solid powder cosmetic of the present invention may contain components usually used in cosmetics, quasi drugs and the like. For example, water, oil, moisturizer,
Surfactants, dispersants, powders, preservatives, perfumes, agents, thickeners and the like can be mentioned.

As the powder, any powder such as an inorganic powder, an organic powder, a metal pigment and the like can be blended. More specifically, talc, mica, kaolin, calcium carbonate, zinc white, titanium dioxide, red iron oxide, yellow iron oxide, black iron oxide, ultramarine blue, bismuth oxychloride, chromium hydroxide, mica titanium, aluminum oxide, cobalt, navy blue. , Spherical resin powders such as carbon black, magnesium silicate, nylon and PMMA. Further, the powder may be blended after being subjected to a silicone treatment, a metal soap treatment, a fatty acid treatment, a surfactant treatment, a treatment with an acid, an alkali or an inorganic salt, or a composite treatment thereof.

As the oil component, an oil component other than hydrocarbon wax can be blended, for example, silicone wax,
Silicone oils such as decamethylcyclopentasiloxane, methylpolysiloxane, methylphenylpolysiloxane, fluorinated oils such as fluorocarbons, cetylisooctanoate, glyceryltrihexanoate, ester oils such as isopropylmyristate, petroleum jelly, Hydrocarbon oils such as liquid paraffin and squalane, castor oil, olive oil, camellia oil, jojoba oil, natural animal and vegetable oils such as lanolin,
Examples include higher alcohols.

Examples of moisturizers include polyhydric alcohols such as dynamite glycerin, 1,3-butylene glycol and propylene glycol, water-soluble polymers such as hyaluronic acid and chondroitin sulfate, sodium lactate, sodium citrate and sodium glutamate. 2-pyrrolidone carboxylic acid sodium etc. are mentioned.
