However, since urea is hydrolyzed in an aqueous solution, there are cases in which ammonia is generated to give off a bad odor, and the pH is increased to cause a problem in system stability. Therefore, attempts have been made to stabilize various ureas by blending various components. As a component for stabilizing urea, an amino acid salt (JP-A-59-134707) is used.
