There is the report about the symptom of respiratory irritation in rat and mouse (ACGIH (2001), PATTY (5th, 2001)), and there is the report about respiratory irritation in human (ACGIH (2001), PATTY (5th, 2001), ICSC (2001), HSFS (1999), SITTIG (47th, 2002)). So it is classified into Category 3 (respiratory irritation). Moreover, there is the report about the ataxia, fall of acitivity and coma, but the recover from it in rat (ACGIH(2001)). And there is the report that it causes headache, vomiting, dizziness, staggering, unconsciousness in human (ACGIH (2001), PATTY (5th, 2001), ICSC (2001), SITTIG (47th, 2002)). So it is classified into Category 3 (anesthesia). | |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | Lack of data In addition, Ketone and the related compounds affect the neuropathy called "giant axonal neuropathy" (PATTY (5th, 2001)). Although this compond affect neuropathy in the concentrated doses exceeding greatly the guidance value of 2 in a rat, it is reported by the dose concentration within a guidance value that it is uninfluential (PATTY (5th, 2001)). Moreover, HSFS (1999) states whether neuropathy arises or not is not fully evaluated. |
