Description

  The present invention relates to a cosmetic, and more particularly to a cosmetic useful for improving dullness.

  In the field of cosmetics, “dullness” is a phenomenon that appears with age and is one of the phenomena whose cause has not been elucidated. So-called dullness is a phenomenon that appears in a specific area of the face rather than the entire face, for example, around the eyes, and looks darker and lighter in appearance, and correlates with age as described above. It appears as a phenomenon that makes people aware of age. Since “dullness” is easily observed visually, this countermeasure has been desired. The cause of dullness is, for example, the theory that light transmittance decreases due to denaturation of stratum corneum cells and the protein itself is also denatured and yellowish, resulting in dullness (for example, Patent Document 1). (See Patent Document 2). In addition to the decrease in the intensity of the scattered light, the amount of melanin accumulated in the stratum corneum increases and the permeability is impaired (see, for example, Patent Document 3) or melanin There is a theory that the skin surface hue is caused by non-uniformity of the granule distribution and micro blood flow distribution (see, for example, Patent Document 4). There are different ways to deal with these phenomena that are considered to be the cause. For example, if the stratum corneum is denatured, it may be possible to remove old stratum corneum cells using a stratum corneum release agent, If it is due to skin surface shape, moisturizing agent can be administered, if melanin is accumulated, treatment with melanin production inhibitor is effective, and if blood flow is uneven, blood flow improver It is thought that the treatment by is effective. Actually, all of these have moderate effects, and it is considered that “dullness” generation is caused by a combination of various causes. Therefore, even if a certain degree of improvement is certainly recognized only by solving each cause, the present situation is that the cosmetic user is not satisfied.

  On the other hand, hesperidin such as hesperidin and α-glycosyl hesperidin and / or glycoside thereof has an effect of promoting metabolism (for example, see Patent Document 5) and an effect of improving blood flow (for example, see Patent Document 6). It is known that ginseng extract improves blood flow and has a protective action against ischemia. However, for the purpose of improving the dullness of the skin, it is not known at all to use both of them at the same time.

  ADVANTAGE OF THE INVENTION According to this invention, the cosmetics excellent in the dullness improvement effect can be provided.

(1) Ginsenoside which is an essential component of the cosmetic of the present invention The cosmetic of the present invention contains 0.01 to 0.5% by mass, more preferably 0.02 to 0.1% by mass of ginsenoside as an essential component. It is characterized by doing. Here, ginsenoside is a general term for terpene glycosides contained in the roots of the asteraceae ginseng, and for example, ginsenoside Rg1, ginsenoside Rg2, ginsenoside Rg3, ginsenoside Rh1, ginsenoside Rh2, etc. are known as representative ones. Yes. Such ginsenosides usually contain about 0.1 to 0.5% by mass in the residue in a state where water extraction is performed and the solvent is removed. Moreover, when extracting only with alcohol, such as ethanol, 1-4 mass% is contained in the residue which removed the solvent. When an alcohol water mixing medium such as an ethanol aqueous solution is used, 30 to 60% by mass is contained in the residue from which the solvent has been removed. A particularly preferred hydroalcoholic solvent mixture is a 75-85% aqueous ethanol solution. The content of ginsenoside can be quantified by high performance liquid chromatography using an amino group-modified silica column. The quantification may be performed by comparing with a standard sample, and the conditions for high performance liquid chromatography are preferably 95% acetonitrile aqueous solution for the mobile phase. Detection is preferably performed by absorption in the ultraviolet region of 210 nm. To extract ginsenoside from ginseng, the root of ginseng is shredded, 1 to 10 times the amount of solvent is added, and it is immersed for several days at room temperature or for several hours under warming conditions. After the immersion, insoluble matters are removed by filtration as necessary, and the solvent may be removed by distillation under reduced pressure or freeze drying. A production example is shown below. In the cosmetics of the present invention, such ginsenoside works with hesperidin and its glycosides described later to improve local blood flow, regulate the skin microstructure, and inhibit the production of melanin pigments. Exhibits the effect of improving dullness.

<Production Example 1>
1 kg of dried ginseng root was chopped, 10 l of water was added thereto, and the mixture was heated at 90 ° C. for 4 hours. Insolubles were removed by filtration and lyophilized to obtain 0.98 g of amorphous. When this product was analyzed under the above-mentioned high performance liquid chromatography conditions, it contained 0.3% by mass of ginsenoside Rg2. (Extract 1)

<Production Example 2>
The extraction solvent of Production Example 1 was changed to a 75% ethanol aqueous solution, the concentration was distilled off under reduced pressure, and then the combination was changed to a freeze-drying combination. 56 g was obtained. (Extract 2)

<Production Example 3>
The extraction solvent of Production Example 1 was changed to ethanol and the concentration was changed to distillation under reduced pressure, and the same examination was performed to obtain 1.12 g of amorphous containing 1.1% by mass of ginsenoside Rg2. (Extract 3)

And Examples of hesperidin and / or its glycoside include hesperidin, α-glycosyl hesperidin, α-mannosyl hesperidin and the like. Hesperidin is a heparetin rutinose glycoside, which is a flavanone, also called vitamin P. Hesperidin is present in the peel of citrus fruits and is obtained by extraction. Α-glycosyl hesperidin can be obtained by glycosylating such hesperidin using an enzyme such as glucosidase. Regarding α-glycosyl hesperidin, a commercial product already exists, and it is also possible in the present invention to purchase and use such a commercial product. Among these commercially available products, α-glucosyl hesperidin sold by Ezaki Glico Co., Ltd. or Toyo Seika Co., Ltd. is particularly preferable. In the cosmetic of the present invention, such hesperidin and / or its glycoside works together with the ginsenoside to improve the local blood flow, regulate the skin microstructure, and inhibit the production of melanin pigment. And exerts an effect of improving dullness. In order to exert such an effect, the hesperidin or a glycoside thereof can contain only one species, or can contain two or more species in combination. In order to exert such an effect, the total amount of hesperidin and / or its glycoside is 0.0001 to 0.05% by mass, more preferably 0.0005 to 0%, based on the total amount of the cosmetic. It is preferable to contain 0.02 mass%.

(3) Cosmetics of the present invention The cosmetic of the present invention comprises 1) 0.01-0.5% by mass of ginsenoside, and 2) 0.0001-0.05% by mass of hesperidin and / or its glycoside. It is characterized by containing. In addition, the combination of these components has the effect of improving the dullness by improving the local blood flow, adjusting the fine structure of the skin, and inhibiting the production of melanin pigment. Thereby, since the element of a dullness can be improved in many ways, it has the dullness improvement effect excellent compared with the conventional cosmetics.

  In addition to these essential components, the cosmetic of the present invention can contain components having a favorable effect on dullness. Preferred examples of such a component that exhibits a favorable effect on dullness include astilbine that suppresses inflammation and adjusts the properties of the skin by moisturizing, betulinic acid having a nonuniformity-improving action, and / or a salt thereof.

  Astilbin is preferably contained in an amount of 1 μM to 1000 μM in terms of effect and stability of the system, and in order to contain such an amount, the alcohol of walnut (Engelhardtiachrisolepis) leaves, preferably a large amount It is preferable to contain it as a monohydric alcohol, particularly preferably 1,3-butanediol extract. This is because when Koki leaves are extracted with water or the like, such components are hardly extracted. Below, the manufacture example of an extract is shown.
