Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cosmetic containing spherical chitin powder. This cosmetic is good in usability, finish, stability, moldability, and impact resistance.

[Prior art and its problems]

Conventional extender pigments for cosmetics include talc, kaolin,
Mica, titanium dioxide, zinc white, resin powder, etc. are used. These are used by determining the blending amount in consideration of the cosmetic's spreadability, adhesion, coverage, gloss, blendability, moldability, impact resistance, etc.

However, cosmetics using conventional cosmetic extender pigments are not always satisfactory in terms of usability, finish, stability, moldability, impact resistance, etc. In other words, in conventional cosmetic extender pigments, in order to improve smoothness and give a transparent finish,
The particle size becomes large to some extent, and in the case of powder molded products, moldability is poor. Spherical powders such as nylon powder and polyethylene powder are also used, but these also have the disadvantage of poor moldability. In addition, titanium dioxide, kaolin, zinc white, talc, etc. are used to improve moldability, but when large amounts of these are blended, they have the drawback of poor spreadability, powdery finish, and easy caking. Furthermore, powders such as mica, talc, and resin powder are blended into liquid cosmetics to improve blendability and give a light feel, but this has the disadvantage of poor stability.

[Object and structure of the invention]

In view of these circumstances, the present inventors aimed to improve the usability, finish, and stability of cosmetics in order to overcome the problems of the prior art.
As a result of extensive research into moldability, impact resistance, etc., we found that cosmetics containing spherical chitin powder spread well, have a non-powdery finish, are transparent, clean, and have good moldability. Good, no caking, and even with liquid cosmetics,
They found that it is light and has good stability, and based on this knowledge, they completed the present invention.

That is, the present invention is a cosmetic containing spherical chitin powder.

Hereinafter, the configuration of the present invention will be explained in detail.

Chitin exists in the exoskeleton of crustaceans such as crabs and shrimp, and in the hyphae of molds, and chemically, it is a polysaccharide consisting of amino sugars.
It is a seed.

The spherical chitin powder in the present invention preferably has an average particle size of 40 μm or less, particularly 20 to 0.1 μm. If the average particle size significantly exceeds 40 μm, the skin may feel rough and lose its smooth feel.

Although the blending amount varies depending on the intended cosmetic, it is usually 0.1 to 80% by weight, preferably 1 to 60% by weight for the entire cosmetic. When the blending amount is 0.1% by weight, the effect of spherical chitin powder has been developed and it can be produced by the method disclosed in Japanese Patent Application No. 60-240896, which was previously filed.

In this method, recycled chitin is pulverized in water to form a dispersion, and the chitin dispersion is discharged together with gas into a high-temperature atmosphere and dried.

The regenerated chitin used in this method is not the raw chitin obtained by mechanically pulverizing chitin, but the regenerated chitin that is obtained by pulverizing chitin or its low molecular weight products to obtain a suspension of ultrafine chitin particles. , for example, regenerated chitin obtained by the method described below.

i) Coagulated regenerated chitin obtained by converting chitin into an aqueous alkaline chitin solution, coagulating and precipitating it in an acidic aqueous solution, and washing this with water until it becomes neutral.

ii) A coagulated regenerated chitin obtained by dissolving chitin in a mixed solvent of dimethylacetamide and lithium chloride, dropping it into water, alcohol, or acetone to coagulate and precipitate it, and then washing thoroughly with water.

iii) After dissolving chitosan in an acidic solution and coagulating and regenerating it in a basic solution, the regenerated chitosan obtained by washing thoroughly with water until it becomes neutral is replaced with water with alcohol and then contacted with an acetylation reagent in an organic solvent. After reacting to regenerate chitin,
Regenerated chitin obtained by washing with alcohol again and then washing thoroughly with water until it becomes neutral.

The above methods for producing regenerated chitin in i) to iii) will be described in more detail.

First, a method for producing regenerated chitin using method 1) will be described.

To obtain regenerated chitin by coagulating and precipitating an aqueous alkali chitin solution in an acidic solution, for example, water is preferably added to chitin at a weight ratio of 1 part chitin to 15 to 20 parts water, and the mixture is pressurized in a pressure cooker. Conditions 1.2kg/cut, 121
C. for 30 minutes, water was removed, and the sample was immersed in 48.degree. Be caustic soda for swelling. This is frozen overnight at -20°C or lower, then thawed at 15°C or lower, and the caustic soda is removed. It is preferable to perform compression filtration, add caustic soda again, and repeat freezing and thawing. Add ice water to this and bring it to 15℃.
The mixture is preferably stirred at a temperature below 5°C. In this case, if the temperature is 5° C. or higher, the solution tends to coagulate, and if it is 15° C. or higher, the deacetylation reaction proceeds and tends to form chitosan, which is not preferable. The weight ratio of ice water and chitin is preferably 10 to 50 ice water to 1 chitin. The obtained solution is filtered to obtain a uniform aqueous alkali chitin solution from which insoluble substances and the like are removed.

This alkaline chitin aqueous solution is dropped into an acidic aqueous solution to coagulate and precipitate. The acidic aqueous solution depends on the concentration of the alkaline chitin aqueous solution, but for example, if the concentration is 4 to 8%,
In the case of acetic acid, it is 5 to 100%, preferably 25 to 75%, in the case of sulfuric acid, it is 5 to 25%, preferably 5 to 10%, and in the case of phosphoric acid, it is 5 to 50%, preferably 10 to 40%, and other acids are also used. Applicable. The coagulated and precipitated regenerated chitin is separated by filtration and thoroughly washed until it becomes neutral, and the filtered water is removed by 10% by weight.
A regenerated chitin suspension is obtained by adding the chitin in a range of 40 to 40 ml and finely pulverizing it with a homogenizer or the like.

Next, a method for producing regenerated chitin using method 11) will be described.

Chitin is dissolved in a mixed solvent of 95% by weight of dimethylacetamide and 5% by weight of lithium chloride, and the solution is dropped into water to solidify. Alcohol, acetone, etc. may be used instead of water as the coagulating liquid.

After the coagulated material is filtered off, it is washed repeatedly with water to completely remove the solvent. After washing, the mixture is filtered, water is added, and the mixture is pulverized using a homogenizer or the like to obtain a regenerated chitin suspension.

The method for producing regenerated chitin by method iii) was developed by the present inventor and filed a patent application in the 1980s, with a molecular weight of 1.
Low molecular weight chitosan of 0.000 to 230000 is mixed with acetic acid,
Dissolve in an aqueous solution of dichloroacetic acid, formic acid, etc. singly or in a mixture to obtain an acidic chitosan aqueous solution. The obtained acidic aqueous solution is regenerated in a basic coagulation bath as follows to obtain regenerated chitosan.

When a certain amount of the acidic aqueous solution is dropped into an aqueous solution of an alkaline substance such as sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, ammonia, or ethylenediamine, spherical regenerated chitosan is obtained. In this way, the chitosan is thoroughly washed with water until it becomes neutral, the water is replaced with alcohol, and then the regenerated chitin is obtained by reacting it with acetic anhydride in ethanol, for example, to perform N-acetylation. The regenerated chitin was washed with alcohol and then with water.
Pulverize with a homogenizer or the like to obtain a regenerated chitin suspension.

The regenerated chitin suspension obtained as described above has 100%
Spherical chitin powder with an average particle size of 40 μm or less can be obtained by discharging it together with gas into a high temperature atmosphere of ~180° C. and drying it. When the discharged chitin suspension is dried in a high-temperature atmosphere due to the surface tension of water, which is a dispersion medium, fine spherical powder is formed. When discharging the regenerated chitin suspension, it is preferable to maintain the dispersibility of the suspension, and this can be done while stirring with a homogenizer or the like. The particle size of the obtained spherical chitin powder can be arbitrarily set by appropriately adjusting the gas discharge pressure, the discharge amount of the suspension, and the concentration of the suspension when discharged into a high-temperature atmosphere.

The spherical chitin powder produced by this method is spherical with a uniform particle size, has extremely excellent dispersibility, and has the advantage that the particles do not aggregate or adhere.

In addition to the above-mentioned spherical chitin powder, the cosmetics of the present invention include:
