1 | Acute toxicity (Inhalation: Gases) | Classification not possible |
- |
- | - | The classification is not possible due to lack of data. An LC50 value (4 hours) of > 10,000 ppm for rats was reported for a mixture consisting of trans-2-butene (55.3 vol%), cis-2-butene (42.4 vol%), and others (n-butane, 1-butene, and so on) (2.3 vol%) (SIDS (2012)). |

2 | Skin corrosion/irritation | Classification not possible |
- |
- | - | The classification is not possible due to lack of data. Besides, there is the information that a liquefied product of 2-butene could cause frostbite in direct contact with skin (SIDS (2012)). |
FY2015 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1)) |
3 | Serious eye damage/eye irritation | Classification not possible |
- |
- | - | The classification is not possible due to lack of data. Besides, there is the information that 1-butene is mildly irritating to eyes (HSDB (Access on June 2015)). |

4 | Respiratory sensitization | Classification not possible |

4 | Skin sensitization | Classification not possible |

- | - | Due to lack of data, the classification is not possible. | FY2015 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1)) |
5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | The classification is not possible due to lack of data. Besides, as in vitro data on a mixture of cis- and trans-isomers, 2-butene was reported to be negative in a bacterial reverse mutation test and a chromosomal aberration test using rat peripheral blood lymphocytes. (SIDS (2012), ACGIH (7th, 2001)) |

6 | Carcinogenicity | Classification not possible |
- |
- | - | For this substance, no carcinogenicity test was reported, and no international classification was internationally conducted. Therefore, the classification is not possible due to lack of data. |
FY2015 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1)) |
7 | Reproductive toxicity | Classification not possible |
- |
- | - | There is no report on reproductive/developmental effects by exposure to this substance only. Besides, in a combined repeated dose toxicity study with reproduction/developmental toxicity screening test (OECD TG 422) using rats with an inhalation route on 2-butene (a mixture of cis- and trans-isomers), no effect on fertility of parent animals and growth of the offspring until four days after birth were observed (SIDS (2012), ACGIH (7th, 2008)). However, because it is a screening test, the classification is not possible due to lack of the information with only this result. |

8 | Specific target organ toxicity - Single exposure | Classification not possible |
- |
- | - | As for experimental animals (mice), there is the information that inhalation exposure to this substance (18.7 vol%) caused narcotic effects within 10 minutes and it was reported that an inhalation exposure to this substance of 21.0 vol% (210,000 ppm) caused asphyxia (ACGIH (7th, 2008), SIDS (2012), PATTY (6th, 2012)). Because asphyxia and narcotic effects mentioned above were due to lack of oxygen in a limited space, it was classified as "Classification not possible." |
FY2015 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1)) |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - | No repeated dose toxicity data on this substance. Toxicity information by an inhalation route of experimental animals was obtained on 2-butene (a mixture of cis- and trans-isomers). In a combined repeated dose toxicity study with reproduction/developmental toxicity screening test using rats (OECD TG 422), no effect was observed up to the highest dose of 5,000 ppm (SIDS (2012)). This dose is above a guidance value range of Category 2 and corresponds to "Not classified," however, the classification is not possible because the test is a screening test. Therefore, it was classified as "Classification not possible" due to lack of data. |

11 | Hazardous to the aquatic environment Short term (Acute) | Classification not possible |
- |
- | - | The classification is not possible because appropriate data are not obtained. Besides, in SIDS, a 96-hour EC50 = 15 mg/L for algae, 48-hour EC50 = 23 mg/L for crustacea, and 96-hour LC50 = 21 mg/L for fish as QSAR estimation are reported (all SIDS, 2012), however, they were not used for the classification. |

11 | Hazardous to the aquatic environment Long term (Chronic) | Classification not possible |
- |
- | - | The classification is not possible because appropriate data are not obtained. Besides, in SIDS, a 96-hour chronic value = 1.8 mg/L for algae, a 16-day chronic value = 1.4 mg/L for crustacea, and a 30-day chronic value = 2.9 mg/L for fish as estimation are reported (all SIDS, 2012), however, they were not used for the classification. |
