Solubilization method of benzimidazole-based compound and use thereof

A method for solubilizing a benzimidazole-based compound according to an embodiment includes preparing a first mixture solution by adding a benzimidazole-based compound to a solution in which water and glycerin are mixed with each other and subsequently homogenizing the first mixture, admixing the first mixture solution with plant oil and an emulsifier in order to prepare a second mixture and subsequently homogenizing the second mixture, and after the admixing, allowing the second mixture to stand at 0 to 10° C. for 12 to 48 hours to obtain a solubilized product of the benzimidazole-based compound. The solubilization method is advantageous in that, as the processing is carried out by using a material having no human toxicity, the step of removing solvents that are harmful to human can be omitted, and a solubilized product with human safety and high effect can be provided.
