Widely used in cosmetics and food fields. Vitamin E includes natural vitamin E ((d-α-tocopherol) and non-natural vitamin E (d1-α-tocopherol),
Examples of the fatty acid ester include acetic acid ester, succinic acid ester, nicotinic acid ester and the like (hereinafter commonly referred to as vitamin E). However, since these substances are hardly dissolved in water, it has been considered very difficult to make high-concentration vitamin Es into aqueous preparations such as eye drops, injections and drinks. A method for solubilizing or emulsifying vitamin Es using a nonionic surfactant, lecithin or saponin which is a natural surfactant to prepare an aqueous preparation,
Further, a method of solubilizing or emulsifying using polyglycerin fatty acid ester or alcohol has been studied. However, when vitamin E is blended in a high concentration, lecithin has a difficulty in its chemical stability, and when a nonionic surfactant or saponin is used, the addition amount is very large, and alcohols are There is a problem that it is not preferable because of its irritation, and a satisfactory aqueous preparation cannot be provided. As a result of various studies on an aqueous preparation of vitamin E which is satisfactory as a medicine, the present inventors surprisingly can be satisfied as a medicine without using a solubilizer or an emulsifier, when an alkali metal salt of hemisuccinate is used. It has been found that an aqueous formulation is obtained. The aqueous preparation of the present invention is a uniform and highly stable emulsified preparation, which contains vitamin E.
By using the alkali metal salt of the hemisuccinate ester, the uniform and highly stable emulsion preparation can be obtained. Representative examples of the alkali metal include sodium and potassium, which can be appropriately selected.

の安定化を図ることが好ましい。A uniform aqueous emulsion composition can be obtained simply by adding an alkali metal salt of a hemi-succinate ester of vitamin E to water and stirring it. However, in order to obtain a more uniform and stable aqueous emulsion composition, ultrasonic treatment and high-pressure injection are performed. It is preferable to further reduce the particle size of the emulsified droplets by performing an emulsification treatment or a filtration treatment to stabilize the emulsification system.
