1 | Acute toxicity (Dermal) | Classification not possible | - | - | - | - | No data available |
1 | Acute toxicity (Inhalation: Gases) | Not applicable | - | - | - | - | Due to the fact that the substance is "liquid" according to the GHS definition and inhalation of its gas is not expected. |
1 | Acute toxicity (Inhalation: Vapours) | Classification not possible | - | - | - | - | No data available |
1 | Acute toxicity (Inhalation: Dusts and mists) | Not classified | - | - | - | - | Because the rat LC50 value of 4,900ppm, calculated from the testing data of rat LC50 (inhalation of mist) of 24mg/L (4 hours) (CERI Hazard Data 2001-51 (2002)), exceeded the saturated vapour concentration (3,300ppm) under a saturated vapour pressure of 330Pa (25degC) (CERI Hazard Data 2001-51 (2002)), the substance was considered as "mist exposure" and was classified based on standard values expressed in mg/L. |

Based on the description in the report on rabbit skin irritation tests (CERI Hazard Data 2001-51 (2002)): "The substance induced erythema and edema; reported as skin irritant in EEC classification," "moderate irritation observed." Although the results are not those of 4-hour application, the substance is considered "moderately irritating" and classified into Category 2. | |

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. |
Based on the description in the report on rabbit eye irritation tests (CERI Hazard Data 2001-51 (2002)): "mildly irritating" (though exposure duration is unknown). |
4 | Respiratory sensitization | Classification not possible | - | - | - | - | A case of human occupational exposure is reported in CERI Hazard Data 2001-51 (2002); "27 workers who had been exposed to the substance for several years throughout manufacturing process of products containing 30% 1,3,5-trimethylbenzene and 50% 1,2,4-trimethylbenzene (hydrocarbon concentration of vapour: 10-60ppm) exhibited symptoms of oversensitiveness, tension, anxiety and bronchial asthma." However, the material contained isomers and no information is available on 1,3,5-trimethylbenzene per se, it was decided not to use this specific observation for classification. |
4 | Skin sensitization | Classification not possible | - | - | - | - | No data available |
5 | Germ cell mutagenicity | Not classified | - | - | - | - | Based on the absence of data on multi-generation mutagenicity tests and germ cell mutagenicity tests in vivo, and negative data on somatic cell mutagenicity tests in vivo (micronucleus tests), described in CERI Hazard Data 2001-51 (2002). |

10 | Aspiration hazard | Category 1 | Danger | H304: May be fatal 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 ... |
Based on the fact that the substance is a hydrocarbon and has a dynamic viscosity of 1.336mm2/s (20degC). |

11 | Hazardous to the aquatic environment (Acute) | Category 2 | - | - | H401: Toxic to aquatic life |
P273: Avoid release to the environment. P501: Dispose of contents/container to ... |
It was classified into Category 2 from 48 hours LC50=6000microg/L of the crustacea (Daphnia magna) (MOE Risk Assessment vol. 2 (2002) and others.). |
11 | Hazardous to the aquatic environment (Long-term) | Category 2 | - | H411: Toxic to aquatic life with long lasting effects |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
Although acute toxicity was Category 2 and the bio-accumulation potential was low (BCF=342(Existing Chemical Safety Inspections Data)), since there was no rapidly degrading (the decomposition by BOD: 0%(Existing Chemical Safety Inspections Data)), it was classified into Category 2. |
