- |
- | - | [Rationale for the Classification] Based on (1), it was classified as "Not classified" in the oral route. However, there was not sufficient information available for classification in the other route. Therefore, classification was not possible due to lack of data. [Evidence Data] (1) It was reported that in an acute oral toxicity test (OECD TG401, GLP) with rats, no effects were observed at 2,000 mg/kg (REACH registration dossier (Accessed May 2020)). |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - | [Rationale for the Classification] Based on (1), it was classified as "Not classified" in the oral route. However, there was not sufficient information available for classification in the other route. Therefore, classification was not possible due to lack of data. [Evidence Data] (1) It was reported that in a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test (OECD TG422, GLP) with rats dosed by gavage (for 29 days (males), 43 to 56 days (females)), higher total protein and albumin levels and higher absolute and relative liver weights in males were observed at 300 mg/kg/day (converted guidance value: 96.7 mg/kg/day (males), within the range for Category 2); and higher liver weights and hypertrophy of the hepatocytes in the centrilobular area of the liver, diffuse hyperplasia/hypertrophy of the follicular epithelium in the thyroid glands, and hypertrophy of the adenohypophyseal cells (multifocal) in the pituitary gland were observed at 1000 mg/kg/day (converted guidance value: 322 to 622 mg/kg/day, in the range corresponding to "Not classified") (REACH registration dossier (Accessed May 2020)). |

11 | Hazardous to the aquatic environment Short term (Acute) | Category 3 |
- |
H402 | P273 P501 |
It was classified in Category 3 from 48-hour EC50 = 59.5 mg/L for crustacea (Daphnia magna) (REACH registration dossier, 2021). |
11 | Hazardous to the aquatic environment Long term (Chronic) | Category 1 |
Warning |
H410 | P273 P391 P501 |
Sufficient data on rapid degradability were not obtained. If chronic toxicity data are used, then it is classified in Category 1 from 72-hour NOErC = 0.052 mg/L for algae (Raphidocelis subcapitata) (REACH registration dossier, 2021). If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, then it is classified in Category 3 from 48-hour EC50 = 59.5 mg/L for crustacea (Daphnia magna) (REACH registration dossier, 2021). By drawing a comparison between the above results, it was classified in Category 1. |
