---|---|---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Not classified |
- |
- | - | Since its rat LD50 values are reported to be 12300 mg/kg and 13200 mg/kg using technical grade test substance (IUCLID (2000)), the substance was classified into "Not classified". | FY2008 | GHS Classification Guidance by the Japanese Government (Sep, 2008) |

2 | Skin corrosion/irritation | Not classified |
- |
- | - | Skin irritation tests using rabbits that received 24-hour exposure found the substance slightly irritating (IUCLID (2000)). In other studies, 20-hour exposure resulted in development of mild and slight rubor (IUCLID (2000)). Based on these results, the substance was classified into "Not classified" using the JIS classification criteria (Category 3 in the United Nations classification). | FY2008 | GHS Classification Guidance by the Japanese Government (Sep, 2008) |
3 | Serious eye damage/eye irritation | Category 2A |
Warning |
H319 | P305+P351+P338 P337+P313 P264 P280 |
Eye irritation tests using rabbits found the substance moderately irritating 24 hour after application (IUCLID (2000)). It is rated as Xi: R36 in the EU classification (EU-Annex 1 (accessed in November 2008)). Based on this information, the substance was classified into Category 2A. | FY2008 | GHS Classification Guidance by the Japanese Government (Sep, 2008) |
4 | Respiratory sensitization | Classification not possible |

Warning |
H317 | P302+P352 P333+P313 P362+P364 P261 P272 P280 P321 P501 |
Two different guinea pig maximization tests found the substance sensitizing (IUCLID (2000)). In addition, several skin sensitizing tests using guinea pigs yielded positive results (IUCLID (2000)). Furthermore, it is rated as R43 in the EU classification (EU-Annex 1 (accessed in November 2008)). Thus, the substance was classified into Category 1. | FY2008 | GHS Classification Guidance by the Japanese Government (Sep, 2008) |
5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | Classification is not possible due to lack of in vivo mutagenicity test data. As additional background information, Ames tests (in vitro mutagenicity tests) gave negative results (NTP DB (accessed in November 2008), IUCLID(2000)). | FY2008 | GHS Classification Guidance by the Japanese Government (Sep, 2008) |

11 | Hazardous to the aquatic environment Short term (Acute) | Not classified |
- |
- | - | It was classified as "Not classified" from 96-hour LC50 = 100.4 mg/L for fish (Pimephales promelas) (ECETOC TR91: 2003). | FY2018 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1)) |
11 | Hazardous to the aquatic environment Long term (Chronic) | Not classified |
- |
- | - | Chronic toxicity data were not obtained. It is not rapidly degradable (not readily degradable, an average degradation rate by BOD: 3% (J-CHECK, 1998)). However, it has no bioaccumulation potential (LogKow: -2.16 (PHYSPROP Database: 2018)), and it was classified as "Not classified" in acute toxicity. Therefore, it was classified as "Not classified." | FY2018 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1)) |
