FIG. 3 is a diagram showing that the stratum corneum moisture content is synergistically improved by using glyceryl glucoside and Cordyceps extract in combination.

  Hereinafter, modes for carrying out the present invention will be described.

  The external preparation for skin of the present invention can be used for any application such as cosmetics, quasi drugs, and pharmaceuticals.

  As long as glyceryl glucoside can be blended in cosmetics, the production method does not matter whether it is a synthetic method or a fermentation method using microorganisms. Specifically, any of α-form, β-form, or a mixture thereof can be used.

  The Kumazasa extract used in the present invention is an extract of Sasa veitchii belonging to the genus Saceae. As the extraction site, one or more selected from leaves, stems, whole grasses and ground sites are used. It is preferable to use leaves. As the Kumazasa extract, commercially available Falco Rex Kumazasa E (manufacturer: Ichimaru Falcos), Kumazasa extract (manufacturer: Maruzen Pharmaceutical), Kumazasa extract (manufacturer: Koei Kogyo Co., Ltd.) and the like can also be used.

  The Murayakoenji extract used in the present invention is an extract of Murraya koenigii (Chalcas koenigii) belonging to the genus Rutaceae. As the extraction site, leaves and branch tips or leaves are used. It is preferable to use leaves. A commercially available Murayaco Enzyme extract (manufacturer: Mikimoto Pharmaceutical Co., Ltd.) can also be used as the Murayaco Engi extract.

  Cordyceps used in the present invention is not particularly limited, and forms parasites of the common butterfly moth Lepidoptera and Coleoptera or its larvae to form mycorrhizal bodies in the body. Any fruit body formed on the body surface of the larva may be used. The cordyceps that can be used particularly preferably in the present invention is a corda that parasitizes the larvae of the bat family (Hepialus armoricanus Ober) to form mycorrhiza in the body, and forms a root-rod-like fruit body from the head in the summer. One example is Cordyceps sinensis. In addition, Cordyceps sobolifera B, Cordyceps militaris Link, Cordyceps nutans Pat, etc. are known as medicinal remedies for Cordyceps sinensis other than Cordyceps sinensis, and these are also used in the present invention. It can be preferably used. According to the method of the present invention, these cordyceps can be extracted in any case as long as they produce active ingredients. Moreover, by using the method according to the present invention, it is possible to extract without distinguishing fruit bodies or angioplasts, but in order to obtain a particularly high yield, extraction from the fruit bodies of Cordycepsinensis is preferable.

  The extraction method of the plant extract used in this invention is described.

  In the present invention, each of the above plants may be subjected to extraction as it is, but considering the extraction efficiency, it is preferable to perform extraction after processing such as shredding, drying, and pulverization. Extraction is performed by immersing in an extraction solvent. In order to increase the extraction efficiency, stirring may be performed, or homogenization may be performed in an extraction solvent. The extraction temperature is suitably about 5 ° C. to the boiling point of the extraction solvent. The extraction time varies depending on the type of extraction solvent and the extraction temperature, but is suitably about 4 hours to 14 days.

  Extraction solvents include water, lower alcohols such as methanol, ethanol, propanol, and isopropanol, polyhydric alcohols such as 1,3-butylene glycol, propylene glycol, dipropylene glycol, and glycerin, and ethers such as ethyl ether and propyl ether. , Polar organic solvents such as esters such as ethyl acetate and butyl acetate, and ketones such as acetone and ethyl methyl ketone can be used, and one or more of these are selected and used. Further, physiological saline, phosphate buffer, phosphate buffered saline, or the like may be used.

  The extract of the above-mentioned plant by the above-mentioned solvent can be contained in the composition according to the present invention as it is, but the concentrated and dried solid can be dissolved again in water or a polar solvent, or their skin physiological functions can be improved. It may be used after performing purification treatment such as decolorization, deodorization, desalting or the like within a range not impairing the action, or after fractionation treatment by column chromatography. For storage, it can be freeze-dried after purification and dissolved in a solvent before use. It can also be used by encapsulating in vesicles such as liposomes or microcapsules.

  In particular, when used as an external preparation for skin, the above extract is used by being encapsulated in vesicles such as liposomes, microcapsules or the like, thereby enhancing percutaneous absorption and exhibiting a higher anti-aging effect.

  In addition, it is preferable from the point of the effect of this invention to use a hot-water extract as a method for extracting Cordyceps.

  As a compounding quantity to the composition of the above-mentioned plant in this invention, Preferably it is 0.00001-5 weight%, Especially it is the range of 0.0001-1 weight%. If it is this range, when it mix | blends combining a specific plant, it will not affect the temporal stability of a formulation and a plant in a formulation, and can exhibit a higher effect.

  In addition to the essential components described above, the external preparation for skin of the present invention is usually mixed with an external preparation for skin as needed, an aqueous component, an oily component, a moisturizer, a dye, a surfactant, an ultraviolet absorber, a thickening agent. Agents, cosmetic ingredients, fragrances, polymer substances, antibacterial and antimicrobial agents, alcohols, powders, scrub agents, biogenic ingredients, and the like can be appropriately blended.

  The external preparation for skin of the present invention can be used, for example, in the form of a lotion, emulsion or ointment. Moreover, the skin external preparation of this invention does not ask | require a manufacturing method.
