As the results of a mouse inhalation exposure test of 2-methylcyclohexanone, irritating to the eyes and respiratory tract has been reported PATTY 5th, 2001, and as characteristics of an isomeric mixture of methylcyclohexanones, at low concentrations, it was described to be irritating to the eyes, the nasal cavity, and the throat PATTY 5th, 2001. In addition, anesthesia and hypothermia were observed in rabbits that survived dermal administration of 2-methylcyclohexanone PATTY 5th, 2001, and rabbits or cats became somnolent within one hour after exposure to 2-methylcyclohexanone via inhalation ACGIH 2001. Also as characteristics of high concentration exposure of an isomeric mixture of methylcyclohexanones, inhibition of the central nervous system and anesthesia were indicated PATTY 5th, 2001. Based on the above results, the substance was classified into Category 3 respiratory tract irritation, narcotic effects.
