本発明は安定化されたカルプロニウムクロライド配合
剤に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to stabilized carpronium chloride formulations.
カルプロニウムクロライドは局所血管拡張作用を有す

いるように、極めて利用範囲の広い化合物である。Carpronium chloride is a compound that has a local vasodilatory effect, and is currently widely used as a hair nourishing agent in the form of lotions, creams, sticks, aerosols, shampoos, etc. Furthermore, it is also used for purposes other than hair nourishing agents. It is a compound with an extremely wide range of uses, as its effective use in nutritional skin creams and the like is being considered.

を提供したとは言えない。However, carpronium chloride has the disadvantage of being unstable in water, ie, easily hydrolyzed. The above-mentioned hair nourishing agents, skin nourishing creams, and the like contain more or less water, and they last for a long time from the time they are manufactured until the end of their shelf life. Therefore, it has been difficult to maintain the content of carpronium chloride in the product at the time of manufacture until the expiration date. As a solution to this problem, the patent application
No. 9-58081 (Japanese Unexamined Patent Publication No. 51-143616). According to this, carpronium chloride is stabilized by pat-anile ethyl ether. By the way, one should be careful when administering chemicals to the human body, and even more so, given the strict regulations under the Pharmaceutical Affairs Law, one should be particularly careful about administering pharmacologically active chemicals to the human body. Therefore, it cannot be said that Japanese Patent Application No. 49-58081 provided a satisfactory method for stabilizing carpronium chloride.
本発明は前述のような薬理活性を有する化合物を使用

保存に対しては不充分であると考えられていた。However, as shown in Table 1, the pH adjustment method,
That is, the hydrolysis inhibiting effect differs depending on the type of buffer used. That is, the present inventors have discovered that malic acid buffer has a much higher stabilizing effect than other buffers, and have completed the present invention. As mentioned above, in short-term experiments it was found that the hydrolysis of carpronium chloride was significantly prevented by adjusting the pH to 4-6 with malic acid buffer; Even if pH was adjusted to prevent hydrolysis, it was thought to be insufficient for long-term storage.
しかし、この予想に反して驚くべきことに表2に示され

The carpronium chloride formulation used in the experiment shown in Table 2 contained propylene glycol, fragrances, pigments, etc. in addition to the malate buffer; The stabilizing effect of carpronium chloride was not affected in any way.
以下、実施例によつて本発明を説明する。The present invention will be explained below with reference to Examples.
