Its rat LD50 value of 200 - 400 mg/kg (PATTY (5th, 2001)) is equivalent to the guidance values of Category 3 or 4. The category with higher toxicity was adopted, and the substance was classified into Category 3.
1 Acute toxicity (Dermal) Classification not possible - - - - It is reported that in a test using rabbits, at the dose of 200 mg/kg, no mortality, and at the dose of 2000 mg/kg, two out of three rabbits died, and its LD50 value was determined to be 200 - 2000 mg/kg (IUCLID (2000)). However, due to a lack of data, classification is not possible.
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Liquid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Classification not possible - - - - No data available.
1 Acute toxicity (Inhalation: Dusts and mists) Category 4 Warning H332: Harmful if inhaled P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing.
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.
Based on its rat LC50 value (330 ppm = 1.30 mg/L/6H; 4h-conversion,1.95 mg/L/4H), the substance was classified into Category 4.
2 Skin corrosion/irritation Category 1 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.
P264: Wash ... thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P310: Immediately call a POISON CENTER or doctor/physician.
P321: Specific treatment (see ... on this label).
P363: Wash contaminated clothing before reuse.
P405: Store locked up.
P501: Dispose of contents/container to ...
Since it is documented that in an irritation test with 1-h exposure to mouse skin, it was corrosive (PATTY (5th, 2001)), and in an irritation test using guinea pigs, it resulted in numerous small lesions resembling acid burns (PATTY (5th, 2001)), the substance was classified into Category 1.
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.
Since it is reported that in an irritation test, the substance was corrosive to rabbit eyes (PATTY (5th, 2001)), it was classified into Category 1.
4 Respiratory sensitization Classification not possible - - - - No data available.
4 Skin sensitization Classification not possible - - - - No data available.
5 Germ cell mutagenicity Not classified - - - - Since it is reported that in a micronucleus assay by gavage using mice (OECD TG 474) (in vivo mutagenicity test), no bone marrow toxicity was evident (IUCLID (2000)), the substance was classified into "Not classified". As relevant information, in an Ames test (in vitro mutagenicity test), the substance was negative (IUCLID (2000)).
6 Carcinogenicity Classification not possible - - - - No data available.
7 Reproductive toxicity Category 2 Warning H361: Suspected of damaging fertility or the unborn child P308+P313: IF exposed or concerned: Get medical advice/attention.
P201: Obtain special instructions before use.
P202: Do not handle until all safety precautions have been read and understood.
P281: Use personal protective equipment as required.
P405: Store locked up.
P501: Dispose of contents/container to ...
Since in a developmental toxicity test using rats and mice, no general toxicity in parental animals was described, but abnormalities such as cleft palate were noted (Birth Defects (3rd, 2000)), the substance was classified into Category 2.
8 Specific target organ toxicity - Single exposure Classification not possible - - - - Classification not possible due to lack of data.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - No data available.
10 Aspiration hazard Classification not possible - - - - No data available.

ENVIRONMENTAL HAZARDS

11 Hazardous to the aquatic environment (Acute) Category 3 - - H402: Harmful to aquatic life P273: Avoid release to the environment.
P501: Dispose of contents/container to ...
Since its 48h-EC50 = 12 mg/L for crustaceans (Daphnia sp.) (IUCLID (2000)), the substance was classified into Category 3.
11 Hazardous to the aquatic environment (Long-term) Not classified - - - - Although its preexisting classification for acute toxicity is Category 3, it is rapidly biodegradable (BOD degradability on 28th day, 106% (Biodegradation and Bioconcentration of Existing Chemical Substances under the Chemical Substances Control Law, 2003)) and it is estimated to have low bioconcentration potency (log Pow = -2.38 (PHYSPROP Database, 2008)), and therefore, the substance was classified into "Not classified".
