1 | Acute toxicity (Oral) | Category 4 |
Warning |
H302 |
P301+P312
P264 P270 P330 P501 |
It was classified in Category 4 based on a report on LD50 values of 846 mg/kg (females) and 1,236 mg/kg (males) for rats (SIDS (2007)). |

Warning |
H315 |
P302+P352
P332+P313 P362+P364 P264 P280 P321 |
It is reported in SIDS (2007) that a 30% aqueous solution of this substance was irritating in a skin irritation/corrosion test with rabbits according to the OECD TG 404. Although the degree of irritation was not mentioned, because it is described in SIDS (2007) that amine oxides including this substance were moderately to severely irritating, it was classified in Category 2. |
3 | Serious eye damage/eye irritation | Category 2B |
Warning |
H320 |
P305+P351+P338
P337+P313 P264 |
It was classified in Category 2B because it was reported to be irritating in an eye irritation test with rabbits according to the OECD TG 405 (SIDS (2007)). |

- | - | Classification not possible due to lack of data. |
5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | Classification not possible due to lack of data. There are no in vivo results. As for in vitro, it was negative in a bacterial reverse mutation test (SIDS (2007)). |
6 | Carcinogenicity | Classification not possible |
- |
- | - | Classification not possible due to lack of data. |
7 | Reproductive toxicity | Classification not possible |
- |
- | - | Classification not possible due to lack of data. |

Warning |
H371 |
P308+P311
P260 P264 P270 P405 P501 |
After oral administration to rats, rough coat, hunched posture, calmness, diarrhea, ptosis, ventrolateral recumbency, flat body posture, lowered breathing frequency, stretched legs, rashes, laying on back, yellow/red/green fluid and autolysis in the gastrointestinal tract, pink fluid in the thorax, pale liver (partial), etc. were observed at doses (375-1,500 mg/kg) within the guidance value range (SIDS (2007)). It was judged to be impossible to specify the specific target organ from the above findings, and it was classified in Category 2 (systemic toxicity). |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - | Classification not possible due to lack of data. |
10 | Aspiration hazard | Classification not possible |

11 | Hazardous to the aquatic environment (Acute) | Category 1 |
Warning |
H400 |
P273
P391 P501 |
From 96-hour ErC50 = 0.29 mg/L for algae (Pseudokirchneriella subcapitata) (SIDS, 2007), it was classified in Category 1. |
11 | Hazardous to the aquatic environment (Long-term) | Category 2 |

H411 |
P273
P391 P501 |
If chronic toxicity data are used, then it is classified in Category 2 due to rapid degradability (a degradation rate: 93% (SIDS, 2007)), and 96-hour NOEC = 0.08 mg/L for algae (Pseudokirchneriella subcapitata) (SIDS, 2007). If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, there are data: 96-hour LC50 = 1 mg/L for fish (SIDS, 2007). However, it is rapidly degradable (a degradation rate: 93% (SIDS, 2007)), and low bioaccumulation is estimated (log Kow < 2.7 (in case of the average chain length of C12.6AO) (JSDA, 2010)). Therefore, it is classified as "Not classified." By drawing a comparison between the above results, it was classified in Category 2. |
12 | Hazardous to the ozone layer | Classification not possible |
