Abstract: Disclosed is an antifreezing coolant composition, which does not include glycol but includes environmentally friendly materials, such as a carboxylic acid salt, an anthranilamide compound, a corrosion inhibitor and a triazole compound. The antifreezing coolant composition may form a thin film on the metal surface in cooling systems for vehicles to thereby exhibit high corrosion resistance at low and high temperatures, superior antifreezing performance at low temperatures, and superior cooling performance at high temperatures.

Abstract: The present disclosure relates to a cooling liquid composition for an electric vehicle. The purpose of the composition according to the present disclosure is to effectively control heat generated during the operation of electronic components which are constituent elements of the electric vehicle, thereby enhancing the durability of the components and ensuring stability. The present disclosure has the effect that the anti-corrosion properties between components of a cooling system are excellent, while the effect of the generation of precipitates that form when electricity flows is small.
