SPECIES: Rat ENDPOINT: LD50 VALUE: 682 mg/kg REFERENCE SOURCE: PATTY (5th, 2001) |
| 1 | Acute toxicity （Dermal） | Classification not possible | - | - | - | - | Data is only rat LD50 >2000mg/kg (PATTY (5th, 2001)). Since data is insufficient, it cannot be classified. |
| 1 | Acute toxicity （Inhalation: Gases） | Not applicable | - | - | - | - | Liquid (GHS definition) |
| 1 | Acute toxicity （Inhalation: Vapours） | 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. |
It was classified as Category 4 based on rat LC50 (4h) = 4420ppm (PATTY (5th, 2001)). Since LC50 value was lower than 90% of saturated vapor pressure concentration, the gaseous classification Category was applied for the classification. |
| 1 | Acute toxicity （Inhalation: Dusts and mists） | Classification not possible | - | - | - | - | No data available |
| 2 | Skin corrosion/irritation | Category 3 | - | Warning | H316: Causes mild skin irritation | P332+P313: If skin irritation occurs: Get medical advice/attention. | As results of animal examinations, "Moderate erythema (redness/inflammation)" on rabbits, "pain and skin discoloration" on rats are reported (PATTY (5th, 2001)), however, there are also descriptions that respective irritation disappeared in less than 24 hours or not sustained. Therefore, it was judged to be mild and was classified as Category 3. |
| 3 | Serious eye damage/eye irritation | Category 2A-2B |
|
Warning | H319: Causes serious 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. P280: Wear protective gloves/protective clothing/eye protection/face protection. |
Based on evaluation of "slight irritant" (PATTY (5th, 2001)) and "moderate" (RTECS (2004)) as a result of the eye stimulativeness examination of a rabbit, it was set as Category 2A-2B . |
| 4 | Respiratory sensitization | Classification not possible | - | - | - | - | No data |
| 4 | Skin sensitization | Classification not possible | - | - | - | - | No data |
| 5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
| 6 | Carcinogenicity | Classification not possible | - | - | - | - | No data available |

| 8 | Specific target organ toxicity - Single exposure | Category 1 (central nervous system), Category 3 (respiratory tract irritation) |
|
Danger Warning |
H370: Causes damage to organs (central nervous system) H335: May cause respiratory irritation (respiratory tract irritation) |
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. |
There is the effect to central nervous system (disappearance of righting reflex, incoordination, the abnormalities in a walk, weakness, headache, vomiting) in animal test (PATTY (5th, 2001), IUCLID (2000)), and there is the report that the symptoms such as headache, vomitting, incoordination, weakness even in human (IUCLID (2000), HSDB (2002)). So it is classified into Category 1 (central nervous). Moreover, there is the mild irritation to respiratory mucous membrane in both of human and animal (IUCLID (2000)). So it is classified into Category 3 (respiratory irritation). |
| 9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | Although the examination of inhalation exposure in humans and an animal is carried out, all of a toxic phenomena are mild because of low concentrations. Therefore, since data is insufficient, it cannot be classified. |
| 10 | Aspiration hazard | Classification not possible | - | - | - | - | Classification not possible due to lack of data on an animal experimentation (chemical pneumonia, etc.), though Dynamic viscosity: <=14 mm2/s. |
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 11 | Hazardous to the aquatic environment （Acute） | Category 1 |
|
Warning | H400: Very toxic to aquatic life |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
It was classified into Category 1 from 48-hour EC50=0.077mg/L of Crustacea (Daphnia magna) (MOE eco-toxicity tests of chemicals, 1998). |
| 11 | Hazardous to the aquatic environment （Long-term） | Category 1 |
|
Warning | H410: Very toxic to aquatic life with long lasting effects |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
Classified into Category 1, since acute toxicity was Category 1 and not rapidly degrading (BOD: 0% (existing chemical safety inspections data)), though less bio-accumulative (BCF=70 of diethyl disulfide as degradation product (existing chemical safety inspections data)). |
