<p>Disclosed are: a mold release agent composition which can be used for the casting of a metal or the like and has excellent mold release properties; and a casting method using the mold release agent composition. Specifically disclosed is a mold release agent composition comprising a liquid medium and a nano carbon material (e.g., fullerene) (wherein the composition may be aqueous or oily), wherein the content of the nano carbon material is 0.00005 to 0.01 mass% (preferably 0.0001 to 0.01 mass%) wherein the total amount of the liquid medium and the nano carbon material is 100 mass%; and a mold release agent produced by diluting the mold release agent composition with a diluent, wherein the content of the nano carbon material is 0.0000005 to 0.005 mass% (0.005 to 50 ppm) [preferably 0.00005 to 0.005 mass% (0.5 to 50 ppm )] wherein the total amount of the liquid medium, the nano carbon material and the diluent is 100 mass%.</p> |
