う問題がある。Silicon compounds have recently been found to have various physiological activities, and their introduction into pharmaceuticals, cosmetics, health foods, etc. is being considered, but their stability is poor, so it is difficult to stabilize them by adding various stabilizers. Improvements in performance are being considered. For example, in Japanese Patent Publication No. 46-21695, salicylic acid, mannuronic acid, citric acid, phenol, etc. are added to an aqueous solution of an alkali siliconate to form a complex, and then a cation-exchanged it fat is added while stirring. A method for obtaining a stable aqueous solution with a pH of 1 to 8 is disclosed. In addition, Japanese Patent Publication No. 1811/1983 discloses that after adding an alkaline aqueous solution of an organosilicon compound to an aqueous solution containing an alcohol or a phenolic compound, the ptl of the solution is
A method is disclosed in which a stable aqueous solution is obtained by reducing the value of 13 to 13 or less using a cation exchange resin. However, since these methods use an ion exchange resin, filtration is required, which is complicated and increases costs.
本発明は、イオン交換樹脂を用いることなく、簡単に操
作でき、安価に製造でき、かつ安定性の良好なケイ素化
合物の水溶液を辱ることを目的とする。The object of the present invention is to provide an aqueous solution of a silicon compound which can be easily operated, manufactured at low cost, and has good stability without using an ion exchange resin.
