Rat LD50 value: 23.1mg/kg (ACGIH 7th, 2001), 31mg/kg, about 30mg/kg, about 22mg/kg (DFGOT vol.9, 1998). Calculated based on the data above. Since the calculated values was 22.7mg/kg, it was classified to category 2. | |

It was set as Category 1. Based on the description that three among three cases died by dermal administration of 0.2mg/kg and 0.05mg/kg to rabbits (DFGOT (vol.9, 1998)). | |

Lower value was adopted from rat LC50 (4 hours): 0.007mg/L (2.4ppm) (ACGIH 7th, 2001) and 22.4ppm (equivalent 0.0641mg/L) (DFGOT vol.9, 1998). 2.4 ppm was considered as the steam with almost no mist from vapor pressure. And classified as Category 1 by the ppm concentration standard. | |
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible | - | - | - | - | No data available |
2 | Skin corrosion/irritation | Category 1A-1C | Danger | H314: Causes severe skin burns and eye damage |
P301+P330+P331: IF SWALLOWED: Rinse mouth. Do NOT induce vomiting. P303+P361+P353: IF ON SKIN (or hair): Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower. P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing. P260: Do not breathe dust/fume/gas/mist/vapours/spray.

In the test applied to the skin of the rabbit, from description that inflammatory changes were seen and the serious necrosis (severe necrosis) appeared 1.5 and 15 minutes after apply (DFGOT (9 vol. 1998)), it was judged that there was caustic and was set as Category 1A-1C. [display] It is more desirable to be set as 1A from a viewpoint of safety, when subdivision is necessary to be carried out. | |
3 | Serious eye damage/eye irritation | Category 1 | Danger | H318: Causes serious eye damage |
P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P280: Wear protective gloves/protective clothing/eye protection/face protection. P310: Immediately call a POISON CENTER or doctor/physician. |
It had corrosiveness to the skin. And there is the description that very severe corneal degeneration was acknowledged in the test applied to the eyes of the rabbits (DFGOT (vol.9, 1998)). So we classified it as Category 1. | |
4 | Respiratory sensitization | Classification not possible | - | - | - | - | No data |
4 | Skin sensitization | Category 1 | Warning | H317: May cause an allergic skin reaction |
P302+P352: IF ON SKIN: Wash with plenty of soap and water. P333+P313: If skin irritation or rash occurs: Get medical advice/attention. P261: Avoid breathing dust/fume/gas/mist/vapours/spray. P272: Contaminated work clothing should not be allowed out of the workplace. P280: Wear protective gloves/protective clothing/eye protection/face protection. P321: Specific treatment (see ... on this label). P363: Wash contaminated clothing before reuse. P501: Dispose of contents/container to ... |
We found a description that there was a report of one case in which sensitizing was acknowledged in DFGOT (vol.9, 1998). Moreover, since it is classified into SEN (ACGIH 7th, 2001) according to ACGIH and was classified into Sh (MAK/BAT, 2004) according to DFG, we classified it to be Category 1. Furthermore, DFGOT (vol.9, 1998) has description that severe contact dermatitis was acknowledged in Open Epicutaneous Test which used the guinea pigs. | |
5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | There is the result that the small core examination which used the male rat bone marrow cell of NTP DB (2006) is equivocal, and the result of the micronucleus test which used mouse peripheral blood is negative for a female and equivocal for a male. So it cannot classify according to the shortage of data. |
6 | Carcinogenicity | Classification not possible | - | - | - | - | No data available |
7 | Reproductive toxicity | Classification not possible | - | - | - | - | No data available |
8 | Specific target organ toxicity - Single exposure | Category 1 (respiratory system, kidney), Category 3 (narcotic effects) |
Danger Warning |
H370: Causes damage to organs (respiratory system, kidney) H336: May cause drowsiness or dizziness (narcotic effects) |
P307+P311: IF exposed: Call a POISON CENTER or doctor/physician. P260: Do not breathe dust/fume/gas/mist/vapours/spray. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P321: Specific treatment (see ... on this label). P405: Store locked up. P501: Dispose of contents/container to ... P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing. P403+P233: Store in a well-ventilated place. Keep container tightly closed. P261: Avoid breathing dust/fume/gas/mist/vapours/spray. P271: Use only outdoors or in a well-ventilated area. P312: Call a POISON CENTER or doctor/physician if you feel unwell. |
Because of a description in DFGOT (vol.9, 1998) referring to that effects on respiratory systems were confirmed at concentration within the limits of guidance value of Category 1 through an inhalation exposure test using rats, rabbits, cats, guinea pigs, and mice, and of a description in DFGOT (vol.9, 1998) referring to confirmation of renal damage at a dosage within the limits of guidance value of Category 1 in oral administration studies with rabbits and cats. So it was judged as Category 1 (respiratory organs, kidney). Moreover, it was judged as Category 3 (anesthetic actions) because of a description in DFGOT (vol.9, 1998) referring to that flexion reflex inhibition was confirmed in a inhalation exposure test using rabbits, and of a description in ACGIH (7th, 2001) indicating anesthetic actions as effects on humans. | |
9 | Specific target organ toxicity - Repeated exposure | Category 1 (respiratory system) | Danger | H372: Cause damage to organs through prolonged or repeated exposure (respiratory system) |
P260: Do not breathe dust/fume/gas/mist/vapours/spray. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P314: Get medical advice/attention if you feel unwell. P501: Dispose of contents/container to ... |
It was classified into Category 1 (respiratory tracts) based on description that dyspnea was observed with concentration within the guidance value range for Category 1 in the inhalation exposure test on rats (DFGOT (vol.9, 1998)). | |
10 | Aspiration hazard | Category 2 | Warning | H305: May be harmful if swallowed and enters airways |
P301+P310: IF SWALLOWED: Immediately call a POISON CENTER or doctor/physician. P331: Do NOT induce vomiting. P405: Store locked up. P501: Dispose of contents/container to ... |
Category 2 because of a ketone composed of 13 carbon atoms or less. |
