Description
【0001】
【発明の属する技術分野】
本発明は、保湿性に優れ、肌荒れ改善に優れた皮膚外用剤に関する。
【0002】
【従来の技術】
皮膚外用剤には種々の有効成分が配合されている。保湿効果、肌荒れ改善効果はその薬効のひとつであり,これらの薬効を目的とした化粧品などの皮膚外用剤の有効成分としては,従来より、アミノ酸や多糖、脂質、植物抽出エキスなどが皮膚の炎症や角質層の水分の消失を防ぐ能力に優れているために用いられてきた。植物抽出エキスとしては、アロエエキス、オウバクエキス、キョウカツエキス、クズエキス、甘草エキス、コウホンエキス、サイコエキス、センキュウエキス、トウキエキス、人参エキス、ヨクイニンエキスなどが知られている。
【0003】
【発明が解決しようとする課題】
しかし、上記の有効成分を含有する皮膚外用剤はいずれにおいてもその保湿効果、肌荒れ改善効果は必ずしも十分ではなく、より優れた有効成分の開発が求められていた。本発明は、上記事情に鑑みてなされたものであり、その課題は、保湿性に優れ、肌荒れ改善効果に優れた皮膚外用剤を提供することに有る。
【0004】
【課題を解決するための手段】
本発明者らは、上記課題を解決するために、保湿性に優れ、肌荒れ改善効果に優れた成分を得るべく鋭意研究を重ねた結果、テプイアンタ科(Tepuianthaceae)植物から得られる成分が、保湿性に優れ、肌荒れ改善効果に優れていることを見出し、本発明を完成するに至った。
【0005】
すなわち、本発明は、テプイアンタ科(Tepuianthaceae)植物から得られる成分を含有する皮膚外用剤を提供するものである。
【0006】
【発明の実施の形態】
本発明の実施の形態を説明する。
【0007】

The present inventors have found that the present invention is excellent in the effect of improving skin roughness, and completed the present invention.
[0005]
That is, the present invention provides an external preparation for skin containing a component obtained from a plant of the family Tepuianthaceae .
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described.
[0007]
The Tepuianthaceae plant is composed of five genera of one genus, and grows naturally in the Guiana Highlands in northern South America and in parts of the lowlands of Venezuela and Colombia. The reference species, Tepuianthus auyantepuiensis, is a small shrub 0.5 to 1.5 meters in height, which grows on rocky rocks at the top of Auyan Tepuy in Venezuela. Tepuianthus yapacanensis and Tepuianthus sarisanamensis are found as dwarfed forests in the mountains of Venezuela, and are also found in the southern part of the island of Tepuianthus. It is distributed in the western Savannah region.
[0008]
Next, a method for obtaining a component from a Tepuianta plant will be described. The above-mentioned plants are one or more of various whole plants or leaves, stems, stems, branches, branches and leaves, peels, fruits, bark, sap, seeds, rhizomes, root bark, roots, spikes, head flowers, flowers, etc. Use as is or after drying. As a method for obtaining the components from the Tepuiantaceous plant, the plant body may be used as it is, a processed product such as squeezing may be obtained, or extraction may be performed using an extraction solvent. The extraction solvent is not particularly limited, and monohydric alcohols such as water, ethanol, methanol, isopropanol, isobutanol, n-hexanol, methylamyl alcohol, 2-ethylbutanol, n-octyl alcohol, glycerin, ethylene glycol, ethylene Polyhydric alcohols such as glycol monomethyl ether, propylene glycol, propylene glycol monomethyl ether, propylene glycol monoethyl ether, triethylene glycol, 1,3-butylene glycol, hexylene glycol or derivatives thereof, acetone, methyl ethyl ketone, methyl isobutyl ketone, methyl Ketones such as n-propyl ketone, esters such as ethyl acetate and isopropyl acetate, ethyl ether, isopropyl ether, n-butyl Ethers such as cartel, squalane, petrolatum, paraffin wax, hydrocarbons such as paraffin oil, olive oil, wheat germ oil, rice oil, sesame oil, macadamian nut oil, almond oil, vegetable oils such as coconut oil, tallow, pork Fats and animal fats such as whale oil are exemplified.

Furthermore, it may be used as a fraction using column chromatography or the like. These extracts, purified products, and fractionated products can be dried by removing the solvent therefrom, and further used in the form of a solution solubilized in a solvent such as alcohol or in the form of an emulsion. it can.
[0011]
In the present invention, an excellent skin moisturizing effect and an improved skin roughening effect can be exhibited by blending a component obtained from a Tepuianthaceae plant with a skin external preparation.
[0012]
The amount of the component obtained from the Tepuianthaceae plant in the external preparation for skin is generally 0.000001% by weight to 10.0% by weight, preferably 0.00001% by weight to 5.0% by weight. %, More preferably 0.0001% to 1.0% by weight.
[0013]
When an ingredient obtained from the Tepuianthaceae plant of the present invention is used as an external preparation for skin, it can be in any dosage form such as cream, ointment, lotion, emulsion, solid, powder, and lotion, emulsion, Basic cosmetics such as serums, moisturizing creams, sunscreen creams, sunscreen lotions, suntan oils, sun care products such as carmine lotions, makeup cosmetics such as foundations, eyeliners, mascaras, eye colors, cheek colors, lipsticks It can be provided in the form of a cleansing agent such as a face wash, a body shampoo, a hair shampoo, a rinse, a treatment, a hair cosmetic such as a hair cream, a hair oil, a hair styling agent, a perfume, a deodorant antiperspirant and the like.
[0014]
At that time, as long as the effects of the present invention are not impaired, oily components, surfactants, humectants, pigments, ultraviolet absorbers, antioxidants, fragrances, antibacterial and antifungal agents generally used in external preparations for skin are used. And other raw materials for pharmaceuticals and cosmetics, and physiologically active ingredients such as skin cell activators, anti-inflammatory agents, and whitening agents.
[0015]
【Example】
Next, the present invention will be described in more detail with reference to examples. However, it goes without saying that the present invention is not limited to these examples.
[0016]
First, a preparation example of a component obtained from a plant of the species Tepuianthaceae used in the present invention will be described. Further, in Table 1, the specific names and use site Tepuianta family (Tepuianthaceae) plants used in the present invention, further, describes extract 1 extract 12 extracted in each preparation process.
[0017]
<Preparation Example 1>
The dried plant was immersed in a 10-fold volume of 50% by volume aqueous ethanol solution for 7 days at room temperature. The extract was filtered, concentrated and dried under reduced pressure to obtain an extract.
[0018]
<Preparation Example 2>
The dried plant was immersed at room temperature for 7 days in a 10% by weight 50% by volume aqueous 1,3-butylene glycol solution. The extract was filtered to obtain the desired extract.
[0019]
<Preparation Example 3>
The dried plant is put into an extraction tank of a supercritical fluid extraction device. After adding 0.003% ethanol as an entrainer, 15 MPa carbon dioxide at 40 ° C. was adjusted to a supercritical state while adjusting the flow rate of carbon dioxide under the atmospheric pressure at the outlet of the separation tank to 700 liter / hour. Of carbon dioxide was supplied. Thereafter, the pressure in the extraction tank was reduced, and the extract was taken out.
[0020]
[Table 1]
[0021]
Therefore, we consider blending components obtained from the Tepuianta family (Tepuianthaceae) plants skin external preparation.
[0022]

Was prepared.
[0023]
[Table 2]
[0024]
In Examples 1 to 4 of the present invention, an actual use test for 6 months was performed. A formulation containing no extract was used as a comparative example. In the actual use test, as a panelist, women in their 40s to 60s who remarkably exhibit skin symptoms such as skin hydration and decreased skin elasticity were used as a group of 20 women, and the examples and comparative examples were used for each group. The test was performed with blinds twice a day. Before and after the start of the use test, the condition of the skin was observed, and the effect of improving the skin condition was evaluated in three stages of “improvement”, “slight improvement”, and “no change”. The results are shown in Table 3 by the number of panelists who performed each evaluation.
[0025]
[Table 3]
[0026]
As is clear from Table 3, in Examples 1 to 4 of the present invention, all panelists showed a tendency to improve symptoms. On the other hand, in Comparative Examples in which the components obtained from the Tepuianta plant were not blended, there was no paneler in which both the dry state of the skin and the skin elasticity were clearly improved.
[0027]
Next, in Examples 1 to 4 and Comparative Examples, 20 panelists each having a rough skin condition were used for one month, and the improvement of the rough skin condition was evaluated. The evaluation was performed in three stages of “improvement”, “slight improvement”, and “no change”. The results are shown in Table 4 by the number of panelists who performed each evaluation.
[0028]
[Table 4]
[0029]
As is clear from Table 4, most panelists who used Examples 1 to 4 answered that the rough skin symptoms were slightly improved, and none of the panelists answered that the rough skin symptoms were not improved. On the other hand, in the comparative example in which the extract was not blended, there was no paneler whose skin roughness was clearly improved.
