Provided is a method for producing a homogeneous mixture and the homogeneous mixture using the same. A method for producing a homogeneous mixture comprises stirring two liquid components being immiscible each other; mixing and homogenizing the two liquid components as a first homogenizing stage in a high pressure; applying an ultrasonic wave to the first homogenized two components as a first ultrasonic stage; regulating a weight ratio of the homogeneous components; homogenizing the regulated homogeneous components as a second homogenizing stage in a high pressure; applying an ultrasonic wave to the second homogenized components as a second ultrasonic stage; and generating a homogeneous mixture without any layer separation.
