Rationale for the classification | |
---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification not possible due to lack of data. |
1 | Acute toxicity (Dermal) | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification not possible due to lack of data. |
1 | Acute toxicity (Inhalation: Gases) | Not classified |
- |
- | - | [Rationale for the Classification] Liquid (GHS definition). It was classified as "Not classified." |
1 | Acute toxicity (Inhalation: Vapours) | Category 4 |
Warning |
H332 | P304+P340 P261 P271 P312 |
[Rationale for the Classification] Based on (1), the LC50 was considered to be nearly in the range for Category 4 and it was classified in Category 4. [Evidence Data] (1) LC50 for rats (males) (vapor, 6 hours): between 5.39 to 18.5 mg/L (converted 4-hour equivalent value: 6.6 to 22.7 mg/L, 6.6 mg/L: No death case, 22.7 mg/L: 6 out of 10 rats died) (REACH registration dossier (Accessed May 2021)) |
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification not possible due to lack of data. |
2 | Skin corrosion/irritation | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification not possible due to lack of data. [Reference Data, etc.] (1) It was reported that, in a skin irritation test (equivalent to OECD TG 404, occlusive application for 24 hours, observation for 14 days) for Alkenes (C=6-8, C=7-rich, branched), which was structurally related to this substance, with rabbits (n=8), no dermal irritation was observed in the group treated at 200 mg/kg (mean erythema score after 24/48/72h: 1.88, mean edema score: 0.75). Dermal irritation was observed in the group treated at 3,160 mg/kg (mean erythema score after 24/48/72h: 2.38, mean edema score: 1.5) but it was cleared within 14 days (since the duration of application was long, the findings were not used for classification) (REACH registration dossier (Accessed May 2021)). |
3 | Serious eye damage/eye irritation | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification not possible due to lack of data. [Reference Data, etc.] (1) There was a report (which did not support classification in Category 2B) that, in an acute eye irritation test (equivalent to OECD TG 405, observation for 7 days) for Alkenes (C=6-8, C=7-rich, branched) (CAS RN: 97592-99-9), which was structurally related to this substance, with rabbits (n=6), the eye irritation score was 10.17 and the observed effects were fully reversible within 14 days (REACH registration dossier (Accessed May 2021)). (2) There was a report (which did not support classification in Category 2B) that, in an acute eye irritation test (equivalent to OECD TG 405, observation for 7 days) for Alkenes (C=8-10, C=9-rich, branched) (CAS RN: 97593-01-6), which was structurally related to this substance, with rabbits (n=6), slight conjunctival irritation effects were observed (eye irritation score: 0.33) (REACH registration dossier (Accessed May 2021)). |
4 | Respiratory sensitization | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification not possible due to lack of data. |

7 | Reproductive toxicity | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification not possible due to lack of data. |
8 | Specific target organ toxicity - Single exposure | Category 2 (systemic) |
Warning |
H371 | P308+P311 P260 P264 P270 P405 P501 |
[Rationale for the Classification] Based on (1), since effects by which no target organ could be identified were observed near the upper limit of Category 2, it was classified in Category 2 (systemic toxicity). [Evidence Data] (1) It was reported that in an acute inhalation exposure test (vapor, 6 hours) with rats, such signs as restlessness, periodic eye washing, agitation, and inactivity were observed, and necropsy results indicated discoloration in the lungs and the right kidney at or above 5.39 mg/L (converted 4-hour equivalent value: 6.6 mg/L, within the range for Category 1); and spots on the thymus, darkened areas in the lung and adrenals, etc. were observed in rats that died (6/10 cases) at or above 18.5 mg/L (converted 4-hour equivalent value: 22.7 mg/L, in the range corresponding to "Not classified" (in the vicinity of the upper limit of Category 2)) (REACH registration dossier (Accessed May 2021)). |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification not possible due to lack of data. |
10 | Aspiration hazard | Category 1 |
Danger |
H304 | P301+P310 P331 P405 P501 |
[Rationale for the Classification] Based on (1) and (2), it was classified in Category 1. [Evidence Data] (1) This substance is hydrocarbons. (2) The kinematic viscosity (40 deg C) of this substance (Alkenes (C=7-9-branched, C=8-rich)) is 0.54 mm2/s (cSt) (REACH registration dossier (Accessed May 2021)). |
