AGENT FOR LOWERING VAPOR PRESSURE OF WATER, METHOD FOR PREVENTING SEAL BREAKAGE IN DRAIN TRAP USING AGENT FOR LOWERING VAPOR PRESSURE OF WATER, ANTIFREEZING AGENT FOR WATER, METHOD FOR PREVENTING SEAL BREAKAGE IN DRAIN TRAP USING ANTIFREEZING AGENT FOR WATER, AND ANTIFREEZING AGENT FOR PLANT
It is an object to provide a water vapor pressure lowering agent which is safe, is easily mixed with seal water, and is usable even in a cold region. The water vapor pressure lowering agent includes urea, a surfactant, purified glycerol, and water or alkaline reducing water, and the purified glycerol is obtained by purifying waste glycerol containing ethanol, an oil or fat, water, and a carbide by distillation. In a method for preventing seal breakage in a drain trap T by using the water vapor pressure lowering agent, the vapor pressure lowering agent is introduced such that a liquid level is equal to or higher than a seal water maintenance lower limit in a seal water portion of the drain trap T.
