HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity (Oral) Category 5 - Warning H303: May be harmful if swallowed P312: Call a POISON CENTER or doctor/physician if you feel unwell. Rat LD50 value: 4585mg/kg (ACGIH 7th, 2001, PATTY 4th, 1994), 3200mg/kg (ACGIH 7th, 2001), 4100mg/kg and 2572mg/kg (PATTY 4th, 1994). Calculated based on the data above. Since the calculated values was 2875mg/kg, it was classified to category 5.
1 Acute toxicity (Dermal) Not classified - - - - Based on rabbit LD50 value: 6.35ml/k (reduced value = 5144mg/kg), and >5000mg/kg (ACGIH 7th, 2001, PATTY 4th, 1994), it was set as the outside of Category.
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Liquid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Category 5 - Warning H333: May be harmful if inhaled P304+P312: IF INHALED: Call a POISON CENTER or doctor/physician if you feel unwell. It was classified based on rat LC50 (6 hours) value: 6377ppm (4-hour equivalent: 27.46mg/kg) (PATTY 4th, 1994). Such concentration could be judged to be steam with almost no mist from its vapor pressure, and it was classified as Category 5 by the ppm concentration standards.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible - - - - No data available
2 Skin corrosion/irritation Category 2 Warning H315: Causes skin irritation P302+P352: IF ON SKIN: Wash with plenty of soap and water.
P332+P313: If skin irritation occurs: Get medical advice/attention.
P264: Wash ... thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P321: Specific treatment (see ... on this label).
P362: Take off contaminated clothing and wash before reuse.
There was no animal test data in application of less than 4 hours. But it was set as Category 2 from description that the moderate irritation was admitted in the test applied to the skin of rabbit and guinea pig for 24 hours (PATTY (4th, 1994)).
3 Serious eye damage/eye irritation Category 2B - Warning H320: Causes eye irritation P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
P337+P313: If eye irritation persists: Get medical advice/attention.
P264: Wash ... thoroughly after handling.
We classified it as Category 2B based on the description hat slight damaging property was acknowledged in the test applied to the eyes of the rabbits and it recovered within seven days (PATTY (4th, 1994)).
4 Respiratory sensitization Classification not possible - - - - No data
4 Skin sensitization Classification not possible - - - - Based on the description that skin sensitization was not acknowledged with the guinea pigs in PATTY (4th, 1994), and description that skin sensitization was not acknowledged by the test for human, it may have been Out Of Category, however, the test method was unknown for the test of the guinea pigs, and since test subjects for human was the small-scale test of 25 examples, we thought the data is too insufficient to classify it to be Out Of Category, and we could not classify it.
5 Germ cell mutagenicity Classification not possible - - - - No data available
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 3 (Narcotic effects, Respiratory tract irritation) Warning H335: May cause respiratory irritation (narcotic effects, respiratory tract irritation)
H336: May cause drowsiness or dizziness (narcotic effects, respiratory tract irritation)
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.
P405: Store locked up.
P501: Dispose of contents/container to ...
Because of a description in PATTY (4th, 1994) referring to confirmation of temporary central nervous system depressions in an inhalation exposure test using rats, and of a description referring to that it was used in order to measure relative susceptibility of human lungs to irritant gas. So it was judged that there were anesthetic actions and respiratory irritant, and determined to be Category 3 (anesthetic actions, respiratory irritant).
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - Classification not possible due to lack of data
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.

ENVIRONMENTAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
11 Hazardous to the aquatic environment (Acute) Not classified - - - - It carried out the outside of Category from 96-hour LC50=864mg/L of fishes (Fathead minnows) (ECETOC TR91, 2003).
11 Hazardous to the aquatic environment (Long-term) Not classified - - - - Since not water-insoluble (aqueous solubility =60800mg/L(PHYSPROP Database, 2005)) and acute toxicity is low.
