Rationale for the classification | |
---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Not classified |
- |
- | - | [Rationale for the Classification] It was classified as "Not classified" from (1), (2). [Evidence Data] (1) LD50 for rats: > 5,000 mg/kg (REACH registration dossier (Access on October 2020), BUA 253 (2004)) (2) LD50 for rats: 8,270 mg/kg (REACH registration dossier (Access on October 2020), BUA 253 (2004)) |
1 | Acute toxicity (Dermal) | Not classified |
- |
- | - | [Rationale for the Classification] It was classified as "Not classified" from (1). [Evidence Data] (1) LD50 for rabbits: > 5,000 mg/kg (REACH registration dossier (Access on October 2020), BUA 253 (2004)) |
1 | Acute toxicity (Inhalation: Gases) | Not classified |
- |
- | - | [Rationale for the Classification] Liquid (GHS definition). It was classified as "Not classified." |
1 | Acute toxicity (Inhalation: Vapours) | Classification not possible |
- |
- | - | [Rationale for the Classification] There was information of (1), but because the category cannot be determined, it was classified as "Classification not possible." [Reference Data, etc.] (1) In a test by inhalation exposure to the vapor of this substance in rats, there was no dead animal (0/12) after 8-hour exposure to 0.885 mg/L (converted 4-hour equivalent value: 193 ppm) (REACH registration dossier (Access on October 2020)). |
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification not possible due to lack of data. |
2 | Skin corrosion/irritation | Category 2 |
Warning |
H315 | P302+P352 P332+P313 P362+P364 P264 P280 P321 |
[Rationale for the Classification] It was classified in Category 2 because Category 1 or 2 was estimated from (1), and the possibility of corrosion (Category 1) was considered to be low from (2). Besides, although the name of the skin model was not described in data of (1), it was judged that EpiDerm was used from test conditions, etc., and it was confirmed that it met the acceptance criteria for the current OECD TG 439, judging from test results. [Evidence Data] (1) In an in-vitro skin irritation test using reconstructed human epidermis model according to Draft OECD guideline, it was judged as irritating (REACH registration dossier (Access on November 2020)). (2) In a skin irritation test with rabbits (BASF test), after 1-minute, 5-minute, or 15-minute application to the dorsal skin, slight erythema was observed and disappeared after 6 days, and after 20-hour application to the auricle, well-defined to moderate erythema and edema were found and disappeared after 8 days (REACH registration dossier (Access on November 2020)). |
3 | Serious eye damage/eye irritation | Category 2A |
Warning |
H319 | P305+P351+P338 P337+P313 P264 P280 |
[Rationale for the Classification] It was classified in Category 2A from (1). [Reference Data, etc.] (1) In an eye irritation test with rabbits (BASF test, application amount: 50 microL), no effects on the iris were seen, but irritation reactions were observed in the cornea and conjunctiva and did not disappear by 8 days after application (REACH registration dossier (Access on November 2020)). |
4 | Respiratory sensitization | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification not possible due to lack of data. |
4 | Skin sensitization | Category 1B |
Warning |
H317 | P302+P352 P333+P313 P362+P364 P261 P272 P280 P321 P501 |
[Rationale for the Classification] It was classified in Category 1B from (1). The classification result was changed due to new data obtained. [Evidence Data] (1) In a mouse local lymph node assay (LLNA) according to TG 429, it was judged as positive, and EC3 was reported to be 7.6% (REACH registration dossier (Access on November 2020)). |
5 | Germ cell mutagenicity | Not classified |
- |
- | - | [Rationale for the Classification] It was classified as "Not classified" from (1). [Evidence Data] (1) As for in vitro, it was reported to be negative in a bacterial reverse mutation test, a gene mutation test and a chromosomal aberration test using cultured mammalian cells (REACH registration dossier (Access on October 2020)). |
6 | Carcinogenicity | Classification not possible |
- |
- | - | [Rationale for the Classification] No data available. |
7 | Reproductive toxicity | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification was not possible due to lack of data. |
8 | Specific target organ toxicity - Single exposure | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification was not possible due to lack of data. [Reference Data, etc.] (1) In an acute oral toxicity test with rats (There was no description of the minimum dose at which effects were observed. It was assumed that effects were observed at a dose near the LD50 (8,270 mg/kg) which was lower than the doses exceeding the range for Category 2), dyspnea, apathy, lateral position, staggering, atonia, sedative-like state with loss of corneal and pain reflex, ataxia, spastic movements, diarrhea, salivation, and lacrimation were observed, and in the animals that died, acute dilatation of the heart and acute venous stasis were observed (REACH registration dossier (Access on October 2020)). Since these findings were obtained at an extremely high dose (8,270 mg/kg), they were adopted as reference data. |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification was not possible due to lack of data. [Reference Data, etc.] (1) It was reported that in a three-month feeding test with rats, at 15,000 ppm (converted guidance value: 750 mg/kg/day, exceeding Category 2), reduced body weight gain and shortened prothrombin time were observed, and furthermore, decreases in blood glucose and chlorine level and an increase in potassium level were observed in males (REACH registration dossier (Access on November 2020)). |
10 | Aspiration hazard | Classification not possible |
- |
- | - | [Rationale for the Classification] Classification not possible due to lack of data. |

11 | Hazardous to the aquatic environment Short term (Acute) | Category 2 |
- |
H401 | P273 P501 |
It was classified in Category 2 from 96-hour LC50 = 8.9 mg/L for fish (Danio rerio) (REACH registration dossier, 2021). The classification result was changed from the previous classification by using new information. |
11 | Hazardous to the aquatic environment Long term (Chronic) | Not classified |
- |
- | - | Reliable chronic toxicity data were not obtained. It was classified as "Not classified" because it was rapidly degradable (a 28-day degradation rate by BOD: 73% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, METI, 2012)) and due to a low bioaccumulation estimate (log Kow = 3.3 (REACH registration dossier, 2021)). The classification result was revised from the previous classification by changing how to classify it for chronic toxicity. |
12 | Hazardous to the ozone layer | Classification not possible |
- |
- | - | This substance is not listed in the Annexes to the Montreal Protocol. |
