[Industrial Application Field] The present invention relates to an external preparation having a melanin production inhibiting effect. [Prior art] So-called skin-lightening cosmetics that whiten human skin have long been used as cosmetics that contain peroxides such as hydrogen peroxide, magnesium peroxide, sodium peroxide, and zinc perborate. Ta. However, since these peroxides are extremely unstable substances, they have problems in storage stability and incorporation into cosmetic bases, and furthermore, their skin whitening effects have not been satisfactory. Recently, cosmetics containing vitamin C, cysteine, colloidal sulfur, etc. have been used for the purpose of fairing the skin, but the effects have not yet been sufficiently satisfactory. Furthermore, skin-lightening cosmetics using kojic acid (Japanese Patent Publication No. 56-18569), skin-lightening cosmetics containing derivatives of kojic acid (Japanese Patent Application Laid-open No. 56-79616, JP-A No. 56-7710, JP-A-Sho 56-7710,
59-33207, etc.) are known. In addition, fair skin cosmetics containing quercetin and flavonol compounds (JP-A-55-92305, JP-A-55-92305,
No. 111410, Japanese Patent Application Publication No. 111411, Japanese Patent Application Publication No. 1983-
143908, etc.) are known. On the other hand, vitamin E is a medicine used to treat habitual miscarriages, muscular atrophy, peripheral vascular disorders, heart diseases, etc., and is mainly used internally or as an oil solution injection. In addition, since it has a dilating effect on peripheral blood vessels, vitamin E is formulated into an ointment and marketed as a medicine for chilblains. Furthermore, in addition to the above-mentioned medicinal effects, vitamin E has a reducing effect and is therefore used as an antioxidant in cosmetics, pharmaceuticals, and the like. Furthermore, it is also disclosed that vitamin E is dissolved in water in the form of liposomes to make a whitening lotion and inhibit tyrosylose activity (Japanese Unexamined Patent Publication No. 1986-1999).
Publication No. 75421). [Problems to be solved by the invention] In the conventional technology, among the skin-lightening ingredients used in skin-lightening cosmetics, peroxide is a product that directly oxidizes and bleaches pigments such as melanin produced in the skin.
Excessive use bleaches the skin's original color, making the skin white, which is inconvenient. Moreover, kojic acid, furanobol, etc. suppress melanin production and are used as useful skin-whitening cosmetics. However, if this substance is stored for a long period of time, coloring may occur due to kojic acid. [Means for solving the problem] The present inventors have previously developed vitamin E or vitamin E
We researched the inhibition of melanin production by derivatives, and confirmed the surprising fact that although an aqueous solution of vitamin E does not inhibit tyrosinase activity, it has an extremely excellent melanin production inhibitory effect through tests using mouse melanoma-derived B16 cells. He invented a melanin production inhibiting topical drug containing E and/or its derivatives in a dissolved or suspended state, and filed an application as Japanese Patent Application No. 1983-246890. Recently, when kojic acid was added to a liquid containing the above-mentioned vitamin E and/or its derivatives in a dissolved or suspended state in the aqueous phase of a topical base, vitamin E and kojic acid had a synergistic effect that significantly inhibited melanin production. The present invention was completed based on the discovery that the external preparation containing kojic acid exhibits no coloring caused by long-term storage. The present invention is an external preparation for suppressing melanin production, which is characterized by containing an aqueous solution of kojic acid and/or a kojic acid derivative and an aqueous solution or suspension of vitamin E and/or a vitamin E derivative. The kojic acid derivative used in the present invention is 2-
Benzoyloxymethyl-5-hydroxy-4H
-pyran-4-one, 2-cinnamoyloxymethyl-5-hydroxy-4H-pyran-4-one,
2-phenoxymethyl-5-hydroxy-4H-
Includes pyran-4-one and the like. Vitamin E and vitamin E derivatives used in the present invention include natural vitamin E oil, vitamin E such as α-tocopherol, β-tocopherol, and γ-tocopherol, and vitamin E derivatives such as vitamin E acetate and vitamin E succinate, and their salts. included. External preparations are applied to the skin in the form of emulsions, ointments, pastes, poultices, lotions, etc. to suppress melanin produced in the skin, remove black and brown skin colors, and further inhibit melanin production. It is intended to prevent In order to dissolve the above-mentioned vitamin E and vitamin E derivatives alone or in a mixture of two or more thereof in the aqueous phase of the external drug, vitamin E and/or vitamin E derivatives are water-solubilized to form liposomes with phospholipids. Either make an aqueous solution by making vitamin E and/or a vitamin E derivative in water in the presence of a surfactant or a saponin vitamin E solubilizing agent such as Kyara saponin, or make vitamin E and/or a vitamin E derivative into an aqueous solution using an organic solution. It is dissolved in an organic solvent and mixed into the aqueous phase of an external preparation. In addition, even if the above-mentioned vitamin E and vitamin E derivatives do not completely dissolve in the aqueous phase and are partially suspended, if vitamin E etc. do not separate into the phase, they can be used as the external preparation of the present invention, and The effect can also be fully achieved. It may also be incorporated into the aqueous phase of an external preparation in a suspended state. In this case, surfactants, phospholipids, etc. are used as the suspending agent. When the above-mentioned vitamin E and/or vitamin E derivatives are water-solubilized, and when liposomes of vitamin E and vitamin E derivatives are formed, natural lecithin such as egg yolk lecithin, soybean lecithin, and distearoyl Vitamin E-containing liposomes are made using phospholipids of synthetic lecithin such as lecithin. The manufacturing method involves dissolving phospholipids and vitamin E in a solvent such as chloroform or benzene, distilling the solvent off under reduced pressure using a rotary evaporator, adding a buffer aqueous solution to the resulting thin film, and shaking it vigorously to swell it, forming a multilayer liposome. A method of producing monolamellar liposomes by producing phospholipids and irradiating them with ultrasonic waves. Phospholipids and vitamin E are dissolved in an organic solvent, and this solution is poured into an aqueous buffer solution being stirred to form liposomes. Method for producing phospholipids and vitamin E in chloroform,
A method of manufacturing liposomes by dissolving it in a solvent such as benzene, adding an aqueous buffer solution to it, emulsifying it into a water-in-oil type using ultrasound, distilling off the solvent using a rotary evaporator, and inverting the phase to an oil-in-water type using vortexing. It is manufactured by a known manufacturing method such as. When vitamin E and vitamin E derivatives are solubilized in water using a surfactant, a nonionic surfactant such as polyethylene glycol fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene glycerin fatty acid ester, polyglycerin is used. Fatty acid ester, polyoxyethylene castor oil, polyoxyethylene phytosterol, polyoxyethylene lanolin derivative,
Anionic surfactants such as alkyl ether phosphoric acid such as polyoxyethylene alkyl ether and polyoxyethylene polyoxypropylene alkyl ether are used, and those having an HLB of 15 or more are preferred. Further, when ethanol, propylene glycol, etc. are added to the above-mentioned surfactant, the degree of solubilization is further improved. Further, in order to suspend vitamin E and vitamin E derivatives, the above-mentioned phospholipids, surfactants, etc. are added as suspending agents.
