険性がある。However, when a large amount of a solubilizing agent is used in these, there are disadvantages such as that some of the solubilizing agents have low safety, some have high flammability, and that the product cost is high. . As a method not using a solubilizing agent, there is a method of emulsifying using a suitable emulsifier, but it is difficult to obtain a stable emulsion for a long period of time, and there is a risk that the emulsification is broken and separated.
