Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to cosmetics, and more particularly, to cosmetics containing powder such as makeup cosmetics.

[0002]

2. Description of the Related Art In cosmetics, powders are often contained in expectation of various functions. For example, in basic cosmetics, it is used as an occlusion aid for pack cosmetics for the purpose of efficiently transdermally absorbing an active ingredient, and in make-up cosmetics, optical cosmetics such as color rendering and masking effects are used. It is used as an effective material.
It is also used as an adsorbent for sweat and sebum, regardless of makeup makeup or basic makeup. What greatly affects the function of such a powder is not only its chemical composition but also a microscopic structure such as a crystal structure to a macroscopic structure such as the shape of the powder. It should be noted that physicochemical properties such as optical effects and adsorption properties of powders having the same chemical composition, microscopic crystal structure, etc., even if the macroscopic structures are different, should be especially noted. Will be very different. A good example of this is that the cleaved talc, which is obtained by cleaving the talc in a layer, has physical properties such as an optical effect and a feeling of use that are completely different from those of the original talc. This means that a powder having a new physical shape is important, and development of such a powder is desired.

[0003] On the other hand, regarding shells of shellfish, these shells are composed of an organic calcium compound such as hydroxyapatite and an organic compound such as protein which form a complex structure.
It is known that they are inorganic composite compounds, and it is known that these are pulverized and used for feeds and the like. It was not included in the ingredients. In addition, many of these shellfish shells were usually disposed of simply as waste.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made under such circumstances, and has been developed to provide a powder having excellent physicochemical properties derived from a novel structure and a cosmetic containing the powder. The task is to provide.

[0005]

In view of such circumstances, the present inventors have conducted intensive research efforts to find a powder having a novel structure and excellent physicochemical properties. To 20
A powder having an average particle diameter of 0.1 to 100 μm obtained by adding a baking treatment and a pulverizing treatment at 0 to 1000 ° C. is used to obtain adhesion to the skin, a feeling of use such as slipperiness, and adsorption of sweat and sebum. I found that it was excellent. The present inventors have further studied and found that by incorporating the powder into a cosmetic, it was possible to obtain a cosmetic with less makeup collapse, thereby completing the invention. Hereinafter, the present invention will be described in more detail focusing on embodiments.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION (1) Powder of the Present Invention The powder for cosmetics of the present invention is obtained by subjecting shells of shellfish to a baking treatment and a crushing treatment. The shellfish that can be used as a raw material of the powder for the cosmetic of the present invention is not particularly limited, and any of bivalves, monolamps, and snails can be used. Specifically, clams, clams, clams, oysters, sazae,
Preferred examples thereof include a mussel, a scallops, a scallop, a mussel, a green mussel, a pearl oyster, an abalone, a scallop, a tortoise, a red mussel, a trigger, a tyra mussel and a giant mussel. These can be used solely or in combination of two or more. As a baking process for these shells, leaving the protein in the shells,
In order to make use of this effect, the temperature is preferably 200 to 400 ° C., and if such an organic substance is removed by calcination, and if the effect of voids generated thereby is obtained, 300 to 1 ° C.
000 ° C. is preferred. Since both firings belong to the technical range of the present invention, the firing temperature of the powder of the present invention is 200 to 1
000 ° C. is preferred. In the present invention, the latter firing is preferable from the obtained effects, and a more preferable firing temperature is, for example, 500 to 800 ° C. The firing time is preferably about 1 to 7 days. At this temperature, organic substances can be removed and oven efficiency is high. The pulverizing treatment may be performed by a usual method, and such a method can be exemplified by a crusher mill or the like. The pulverization is preferably performed until the average particle size becomes about 0.1 to 100 mμ. This is because such a particle size is preferable for the feeling of use of the cosmetic. The more preferable average is 1 to 50 mμ, more preferable. If necessary, the particles can be sieved with a shifter or the like, or sieved by a sizing device to make the particle size uniform. Either of the order of the baking treatment and the pulverization treatment may be performed first, but since it is preferable to adjust the particle size last, it is preferable to perform the steps of 1) baking and 2) pulverization. The average particle diameter obtained by adding the baking treatment and the pulverizing treatment at 200 to 1000 ° C. to the shell of the shellfish thus obtained is 0.1 to 0.1%.
The powder of the present invention, which is 100 mμ, has an adhesive property to the skin,
It has the characteristics of being excellent in use feeling such as slipperiness and adsorptive properties such as sweat and sebum. The content of the powder in the cosmetic is preferably 0.1 to 50% by weight, more preferably 1 to 50% by weight.
４０40% by weight.

(2) Cosmetic of the present invention The cosmetic of the present invention is characterized by containing the powder of the present invention. The cosmetic of the present invention can be applied without any particular limitation as long as it is in a form usually used as a cosmetic, but a type usually containing powder is particularly preferred. Such cosmetics include pack cosmetics, massage cosmetics, facial cleansing cosmetics, and the like containing scrubbing agents and the like.
Preferable examples include talcum powders containing a powder that absorbs sweat and sebum, axillary odor control cosmetics, and make-up cosmetics utilizing the optical properties of the powders. Particularly preferred among these are make-up cosmetics. This is because the effect of the powder of the present invention improves the spreadability of the cosmetic and improves the durability and the feeling of use of the cosmetic. The cosmetic of the present invention may contain, in addition to the above-mentioned powder of the present invention, which is an essential component, any component usually used in cosmetics. Such optional components include, for example, hydrocarbons such as squalane, petrolatum, microcrystalline wax, jojoba oil, carnauba wax, esters such as octyldodecyl oleate, triglycerides such as olive oil, tallow, coconut oil, and stearin. Fatty acids such as acid, oleic acid and ritinoleic acid; higher alcohols such as oleyl alcohol, stearyl alcohol and octyldodecanol; anionic surfactants such as sulfosuccinates and sodium polyoxyethylene alkyl sulfate; and amphoteric interfaces such as alkyl betaine salts. Surfactants, cationic surfactants such as dialkylammonium salts, sorbitan fatty acid esters, fatty acid monoglycerides, their polyoxyethylene adducts, polyoxyethylene alkyl ethers, polyoxyethylene Nonionic surfactants such as len fatty acid esters, polyhydric alcohols such as polyethylene glycol, glycerin and 1,3-butanediol, thickening / gelling agents, antioxidants, ultraviolet absorbers, coloring agents, preservatives And powder. In the cosmetic of the present invention, particularly preferred optional components include hydrophobized powders that have been surface-treated with hydrogen methyl polysiloxane, diethanolamine perfluoroalkyl phosphate, silane coupling agents, metal soaps, and the like. This is because the long-lasting makeup is improved in combination with the sweat and sebum-adsorbing action of the powder of the present invention. The preferred content of these hydrophobized powders is 1 to 5
0% by weight, and more preferably 5 to 30% by weight. The cosmetic of the present invention can be produced by treating these essential components and optional components according to a conventional method.
