The statistical calculation of 5 data (ECETOC JACC 19 (1991)) distributed from 346.5 to 590 mg/kg as rat oral LD50 was done and the mean value of 373.6mg/kg was obtained. So it was set as Category 4. | |
1 | Acute toxicity (Dermal) | Category 5 | - | Warning | H313: May be harmful in contact with skin | P312: Call a POISON CENTER or doctor/physician if you feel unwell. | Although three data (ECETOC JACC 19 (1991)) distributed 4380 - 6600 mg/kg was found out as rabbit dermal LD50, it was set as "Category 5" from the lowest data of 4380mg/kg. |

P310: Immediately call a POISON CENTER or doctor/physician. P320: Specific treatment is urgent (see ... on this label). P405: Store locked up. P501: Dispose of contents/container to ... |
Since the mean of 422ppm (2.28mg/L) was obtained with the statistical work of the four data for rat inhalation LC50 distributed 372 - 660ppm (ECETOC JACC 19 (1991)), it was classified as Category 2. | |
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible | - | - | - | - | Classification not possible due to lack of data |
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. |
It was classified as "Category 2" since it was Moderate in the application test on rabbit skin (ECETOC JACC 19 (1991)). | |

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. |
The result of the dose experiment to the eyes of a rabbit was mild (ECETOC JACC 19 (1991)). But R36 is applied in EU. Since SIDS (1998) was also set to irritant to eyes, it was set as "Category 2B." |
4 | Respiratory sensitization | Classification not possible | - | - | - | - | There was no information and we could not classify it. |
4 | Skin sensitization | Not classified | - | - | - | - | There were two experiment results with guinea pigs, both of which were negative (Source: DFGOT vol.6 (1993) and ECETOC JACC 19 (1991)), so we classified them to be "Out Of Category." |
5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | Since there were no in vivo experimental results, we could not classify it. There were five in vitro experiment reports and all of them were negative. |
6 | Carcinogenicity | Classification not possible | - | - | - | - | Since there is no judgment of classification organizations, it cannot be classified. In two caces of rat test reporting, it is judged with negativity (DFGOT vol.6 (1993), ECETOC JACC 19 (1991)). |
7 | Reproductive toxicity | Not classified | - | - | - | - | It was considered as "out of category "since it had no influence in the feeding administration experiments to pregnant female (ECETOC JACC 19 (1991)), the intragastric administration experiment to the male and female including delivery periods (Ministry of Health and Welfare reports (2006)), and a three generation feeding administration experiments (ECETOC JACC 19 (1991)). |

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 are the effects on the respiratory systems, kidney, liver and paralysis of the extremities are reported by rat inhalation exposure equivalent to the guidance value of Category 1. And anesthesia conditions is regarded by oral treatment to mink (DFGOT vol.6 (1993)). So it is classified into "Category 1 (the respiratory system, liver, kidney), Category 3 (anesthetic actions)". | |
9 | Specific target organ toxicity - Repeated exposure | Category 1 (kidney), Category 2 (circulatory system, liver, lung) |
Danger Warning |
H372: Cause damage to organs through prolonged or repeated exposure (kidney) H373: May cause damage to organs through prolonged or repeated exposure (circulatory system, liver, lung) |
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 ... |
In rat inhalation exposure test, the influence on the kidney within the guidance value of Category 1 is reported (ECETOC JACC 19 (1991)), and the influence on lungs is further reported within the guidance value of Category 2 (ACGIH (2001)). Moreover, in the rat oral administration within the guidance value of Category 2, since the influence to the circulatory organ and liver (Ministry of Health and Welfare reports (2006)) was observed, it was classified into "Category 1 (kidney), Category 2 (cardiovascular,liver,lung)." | |
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 ... |
Although it is a polycyclic hydrocarbon corresponded by dynamic viscosity, the industrial products contain monocyclic substance (cyclopentadiene) a lot. We classified it as "Category 1." |

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 96-hour LC50=4.3mg/L of fishes (Oryzias latipes) (SIDS, 2002). |
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 ... |
Classified into Category 2, since acute toxicity was Category 2 and not rapidly degrading (BOD: 0% (existing chemical safety inspections data)), though less bio-accumulative (BCF=384 (existing chemical safety inspections data)). |
