---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Category 4 |
Warning |
H302 |
P301+P312
P264 P270 P330 P501 |
[Rationale for the Classification] Based on (1), it was classified in Category 4. [Evidence Data] (1) LD50 for rats: 1,320 mg/kg (PATTY (6th, 2012), HSDB (Access on May 2019)) |
1 | Acute toxicity (Dermal) | * |
- |
- | - |
[Rationale for the Classification] Based on (1), it was classified as "Not classified." [Evidence Data] (1) LD50 for rats: > 3,000 mg/kg (REACH registration dossier (Access on July 2019)) |
1 | Acute toxicity (Inhalation: Gases) | * |

- |
- | - |
[Rationale for the Classification] Classification not possible due to lack of data. |
2 | Skin corrosion/irritation | * |
- |
- | - |
[Rationale for the Classification] Based on (1), it was classified as "Not classified." Besides, the category was changed since new data was obtained. [Evidence Data] (1) It was reported that in a skin irritation test according to OECD TG 404, the mean scores were 0.56 for erythema and 0 for edema, and the primary dermal irritation index (PII) was 0.5 (REACH registration dossier (Access on June 2019)). [Reference Data, etc.] (2) This substance may cause eye, skin, and respiratory tract irritation (PATTY (6th, 2012)). |
3 | Serious eye damage/eye irritation | Category 2B |
Warning |
H320 |
P305+P351+P338
P337+P313 P264 |
[Rationale for the Classification] Based on (1), it was classified in Category 2B. [Evidence Data] (1) In an eye irritation test according to OECD TG 405, slight irritation in the conjunctiva was observed, but all this disappeared after 7 days. It was reported that the mean scores for corneal opacity, iris, and conjunctiva at 24, 48, and 72 hours were 0, 0, and 2.5, respectively, whereas conjunctiva effects were resolved at 24 hours (REACH registration dossier (Access on June 2019)). [Reference Data, etc.] (2) This substance may cause eye, skin, and respiratory tract irritation (PATTY (6th, 2012), HSDB (Access on May 2019)). |
4 | Respiratory sensitization | * |
- |
- | - |
[Rationale for the Classification] Classification not possible due to lack of data. |
4 | Skin sensitization | * |
- |
- | - |
[Rationale for the Classification] Based on (1), it was classified as "Not classified." Besides, the category was changed since new data was obtained. [Evidence Data] (1) In a skin sensitization test with guinea pigs according to OECD TG 406 (guinea pig maximisation test), no skin reaction was observed, and it was judged to be non sensitising (REACH registration dossier (Access on June 2019)). |
5 | Germ cell mutagenicity | * |
- |
- | - |
[Rationale for the Classification] Based on (1) and (2), since it was all negative in standard combination tests including in vivo and in vitro, it corresponds to "Classification not possible" of the GHS classification guidance for the Japanese government. Therefore, it was classified as "Not classified." Since new data were available, the classification result was changed from the previous classification. [Evidence Data] (1) As for in vivo, it was negative in a micronucleus test with mice (REACH registration dossier (Access on July 2019)). (2) As for in vitro, negative results were obtained in bacterial reverse mutation tests and a chromosomal aberration test with cultured mammalian cells (PATTY (6th, 2012), NTP DB (Access on May 2019)). |
6 | Carcinogenicity | * |
- |
- | - |
[Rationale for the Classification] There were no data available for classification or carcinogenicity classifications by international organizations. Therefore, it was classified as "Classification not possible." [Reference Data, etc.] (1) In a test (animal species unknown) in which this substance was administered by intramuscular injection (total dose: 5,175 mg/kg) for 2 years, tumors were observed at the injection site (PATTY (6th, 2012)). |
7 | Reproductive toxicity | Category 2 |
Warning |
H361 |
P308+P313
P201 P202 P280 P405 P501 |
[Rationale for the Classification] Based on (1), it was classified in Category 2. Besides, the classification result was changed from the previous classification since new information was added. [Evidence Data] (1) In a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test (OECD TG 422) with rats dosed by gavage, clear effects on reproduction (decreased fertility, pre-implantation loss and post-implantation loss) were observed at the dose where parental toxicity (decreased body weight gain, decreased erythrocyte count, hemosiderin deposition, etc.) was observed (REACH registration dossier (Access on June 2019)). [Reference Data, etc.] (2) In a 6-month repeated dose toxicity test with dogs by gavage (capsule administration), testicular hypoplasia was observed at 100 and 300 mg/kg/day (ACGIH (7th, 2001), PATTY (6th, 2012)). |
8 | Specific target organ toxicity - Single exposure | * |
- |
- | - |
[Rationale for the Classification] Classification not possible due to lack of data. Although (1) is described, there is no information on the original source, and no details could be confirmed. In the previous classification, it was classified in Category 3 (respiratory tract irritation) based on the same description in PATTY (5th, 2001), but it was judged to be insufficient as evidence for classification. The classification result was changed since there was no other information supporting respiratory tract irritation. [Reference Data, etc.] (1) This substance may cause eye, skin, and respiratory tract irritation (PATTY (6th, 2012), HSDB (Access on May 2019)). |
9 | Specific target organ toxicity - Repeated exposure | Category 1 (respiratory organs) |
Danger |
H372 |
P260
P264 P270 P314 P501 |
[Rationale for the Classification] Based on (1) and (2), since lesions were observed in the nasal cavity within the range of Category 1 by inhalation exposure of experimental animals, it was classified in Category 1 (respiratory organs). Besides, the dose conversion and target organs in the previous classification were reviewed and the classification result was changed. [Evidence Data] (1) When rats and mice were exposed to the vapour at 3-30 mg/m3 (converted guidance value: 0.002-0.02 mg/L, within the range of Category 1) by inhalation for 13 weeks (6 hours/day, 5 days/week), iron accumulation in the nose, larynx, trachea, lungs, and liver, and dose-dependent nasal lesions (necrosis, inflammation, metaplasia, and regeneration) were observed, and increased liver weight, etc. were observed at or above 10 mg/m3 (PATTY (6th, 2012)). (2) When rats and mice were exposed to the vapour at 2.5-40 mg/m3 (converted guidance value: 0.0004-0.006 mg/L, within the range of Category 1) by inhalation for 2 weeks (6 hours/day), inflammation of the nasal turbinates and decreased body weight gain were observed (PATTY (6th, 2012)). |
