DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a cosmetic containing a serum-free protein-coated pigment, and more specifically, a cosmetic for preventing or improving rough skin and rough lips.

[0002]

2. Description of the Related Art Conventionally, various raw materials extracted from natural products, for example, proteins, polysaccharides, extracted extracts, natural polymers, etc., have been blended with cosmetics intended to prevent or improve skin and lip roughness.

[0003] However, when these components are mixed with various cosmetics, odor, discoloration, separation, etc. may occur at the time and date, and the amount of these components is limited in terms of stability.
In addition, these components are not sufficient for the effect of preventing or improving the rough skin and the rough lips, and furthermore, they have an unpleasant sensation at the time of application and a feeling of moderate moistness is not obtained. From the point of view, it was not yet satisfactory.

[0004]

SUMMARY OF THE INVENTION In view of such circumstances, the present inventors have conducted intensive studies in order to obtain a cosmetic having a truly excellent effect of preventing or improving rough skin and rough lips. It has been found that cosmetics containing serum-deproteinized pigments obtained by a drying method, which have an effect of preventing or improving rough skin and rough lips, can be satisfied in terms of sensory quality, and the present invention. Was completed.

[0005]

That is, the present invention provides a cosmetic comprising a serum-deproteinized pigment obtained by a freeze-drying method.

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

[0007] Serum deproteinization and the like used in the present invention can be made from blood, serum, lymph, placenta extract and the like of calves and the like as raw materials. From these raw materials, protein removal treatment, low temperature treatment,
The target extract is obtained according to a conventional method such as a fat-soluble component removal treatment. The obtained extract has a solid content of 4 to 5% and contains peptides having a molecular weight of 3000 or less, amino acids, organic acids, carbohydrates and the like as organic substances, and has an effect of promoting tissue respiration by activating mitochondrial respiration. Excellent and has high moisture retention. In addition, these extracts were used for solcoseryl (Solcobasel) or S71 (BOTTGER).
Company).

The pigment used in the present invention may be any known powder used as a cosmetic powder.
For example, inorganic powders such as mica, talc, and sericite, and organic powders such as silk powder and nylon powder can be used. Of course, colored powders such as titanium oxide, zinc oxide, iron oxide, gunjo, konjo, and tar dyes can also be used.

The serum deproteinized protein is not always stable to heat and may be denatured. In this case, its effectiveness is lost. Therefore, the coated pigment of the present invention is freeze-dried without a heat step. It is manufactured by using the method.

[0010] The serum-deproteinized pigment of the present invention can be obtained, for example, by the following method. That is, the above-mentioned serum deproteinized substance and the pigment are mixed, and the obtained mixture is pre-frozen, freeze-dried, pulverized and finely powdered to obtain a serum deproteinized pigment.

[0011] The amount (adhesion amount) of the serum deproteinized substance that coats the surface of the pigment is preferably 1 to 200% by weight, more preferably 10 to 100% by weight, based on the weight of the pigment. When the amount is less than 1% by weight, the effect of the present invention is reduced. When the amount is more than 200% by weight, particles of the coated pigment tend to aggregate or solidify, which is not preferable.

The serum-deproteinized coated pigment of the present invention can be incorporated into powder cosmetics and oil-based cosmetics, which were difficult to formulate with serum deproteinized alone, and furthermore, a satisfactory effect can be obtained. I found it.

The serum-deproteinized pigment of the present invention is preferably contained in the cosmetic in an amount of 0.001 to 5.0% by weight, more preferably 0.1 to 0.5% by weight. If the amount is less than 0.001% by weight, it is difficult to sufficiently prevent or improve the roughening of the skin and the lips. Tends to be disadvantageous.

[0014] The cosmetic formulation in which the serum-deproteinized pigment of the present invention can be blended is not limited to powder products, but can also be blended in oily paste products, emulsified products, and the like. , Pack, foundation, lip balm,
Lipsticks, eye shadows, bath additives, body shampoos and the like can be mentioned.

Examples 1 to 4 shown above and Examples 1 to 4
Comparative Example 1 from which the serum-deproteinized pigment was removed from Example 4
Using Nos. 4 to 4, the effects of improving skin roughness and lip roughness were examined, and sensory evaluation was performed at the same time. A woman who has remarkable rough skin and rough lips from winter to dry January to February
Sixty persons were used as panels, and 20 persons were divided into eight groups A to H. Example A in Group A, Comparative Example 1 in Group B, Example 2 in Group C, Comparative Example 2 in Group D, Example 3 in Group E
, Group F, Example 4 for Group G, and Comparative Example 4 for Group H for one month each. The degree of improvement of rough skin and rough lips was classified into four stages of "no improvement", "slight improvement", "improvement", and "significant improvement". Table 1 shows the number of corresponding panels.
The sensory evaluation is "good" for the moist feeling after use.
And the number of respondents was divided into four levels as shown in Table 2, and the evaluation results were indicated by the symbols “◎, ○, Δ, ×”. The test results are shown in Table 3.
