Since its flash point -26 degC (closed-cup) (IUCLID (2000)) is < 23 degC, and initial boiling point 95 degC (Hommel (1996)) is > 35 degC, the substance corresponds to Category 2. As a relevant note, the substance is classified into Class 3, PG II in UNRTDG (UN2278). |
| 7 | Flammable solids | Not applicable | - | - | - | - | Liquid (GHS definition) |
| 8 | Self-reactive substances and mixtures | Type G | - | - | - | - | Although there are chemical groups (an unsaturated bond) present in the molecule associated with self-reactive properties, the substance is classified into Class 3, PGIII in UNTRTDG (UN2278), therefore it is judged that the substance is classified into Type G. |
| 9 | Pyrophoric liquids | Not classified | - | - | - | - | Since its auto ignition point is 250 degC (GESTIS (Access on June. 2010)), and it is considered that the substance does not ignite at room temperature, the substance was classified as "Not classified". |
| 10 | Pyrophoric solids | Not applicable | - | - | - | - | Liquid (GHS definition) |
| 11 | Self-heating substances and mixtures | Classification not possible | - | - | - | - | Test methods applicable to liquid substances are not available. |

| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 1 | Acute toxicity （Oral） | Classification not possible | - | - | - | - | No data were available. Regarding alkenes, C7-9, C8-rich (CAS No. 68526-54-5), rabbit LD50 value of > 5000 mg/kg was documented (SIDS (Access on Jun. 2010)). |
| 1 | Acute toxicity （Dermal） | Not classified | - | - | - | - | No data were available for the substance concerned. Based on the rabbit LD50 value of > 3160 mg/kg (SIDS (Access on Jun. 2010)) for alkenes, C6-8, C7-rich (CAS No. 68526-53-4), the substance was classified as "Not classified" in the JIS classification (corresponding to Category 5 or "Not classified" in the UN-GHS classification). |
| 1 | Acute toxicity （Inhalation: Gases） | Not applicable | - | - | - | - | Liquid (GHS definition) |
| 1 | Acute toxicity （Inhalation: Vapours） | Classification not possible | - | - | - | - | No data were available for the substance concerned. The rat LC50 value of > 10533 ppm/6hrs (= 12900 ppm/4hrs) for alkenes, C6-8, C7-rich (CAS No. 68526-53-4) was documented (SIDS (Access on Jun. 2010)). This information does not allow for the determination of the classification of the substance between Category 4 and "Not classified" category. Thus, the classification was not possible. According to the description of the evaluation document (SIDS (Access on Jun. 2010)), the test condition was vapor state. |
| 1 | Acute toxicity （Inhalation: Dusts and mists） | Classification not possible | - | - | - | - | No data available. |
| 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. |
No test results of the substance concerned were available. The substance was classified as Category 2 based on the documented case of "irritant" resulted from the rabbit test using Alkenes, C6-8, C7-rich (CAS No. 68526-53-4) in which symptoms completely recovered in the low-dose group in 14 days, and moderate edema and severe erythema were continued during tests in the high-dose group (SIDS (Access on Jun. 2010)). |
| 3 | Serious eye damage/eye irritation | Category 2B | - | Warning | H320: Causes 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. |
No test results of the substance concerned were available. The substance was classified as Category 2B based on the documented case of "slight to moderate irritation" resulted from the rabbit test using Alkenes, C6-8, C7-rich (CAS No. 68526-53-4) in which maximum total Draize score was 15 (SIDS (Access on Jun. 2010)). |
| 4 | Respiratory sensitization | Classification not possible | - | - | - | - | No data available. |
| 4 | Skin sensitization | Classification not possible | - | - | - | - | No data available. |
| 5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | No data were available. As relevant information, as for in vivo study, the negative results in the mouse micronucleus test using bone marrow by oral administration (in vivo mutagenicity test in somatic cells) in Alkenes, C6-8, C7 rich (CAS No. 68526-53-4), were reported (SIDS (Access on Jun. 2010)). |

| 7 | Reproductive toxicity | Classification not possible | - | - | - | - | No data available. |
| 8 | Specific target organ toxicity - Single exposure | Classification not possible | - | - | - | - | It was reported that the loss of the righting reflex occurred in mice exposed by inhalation at 60 mg/L, and depression of central nervous system and death at 60 mg/L and 200 mg/L or more (PATTY, 5th (2001)). However, the substance was classified as "Classification not possible", due to lack of information on exposure time. |
| 9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | No data available. |
| 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 there is no data for this substance itself, 1-heptene (CAS 592-76-7) corresponds to Category 1 from the fact that its coefficient of viscosity at 40 degrees centigrade is 0.35 mPa*s (GESTIS (Access on Jun. 2010)) and coefficient of kinematic viscosity at 40 degrees centigrade is 0.5 mm2/s. Although heptene is a mixed isomer, the hazard is sufficiently suggested from the knowledge of 1-heptene. Therefore, the substance was classified as Category 1. |
| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
