Additional information
Acute oral toxicity: an experimental study equivalent to OECD Guideline 401 (1981). Sprague-Dawley rats were administered either 4000 or 5000 mg test item/kg bw (5 female and 5 male animals per dose) and monitored for mortality, clinical symptoms and body weight changes for 15 days, then subjected to gross pathological examination.
The LD50 resulted equal to 5000 mg/kg bw. Based on the read across considerations same results apply to the target substance.
Justification for classification or non-classification
According to Annex I: 3.1.2.1 of the CLP Regulation (EC No. 1272/2008), substances can be allocated to one of four hazard categories based on acute toxicity by the oral, dermal or inhalation route according to the numeric criteria shown in the table below. Acute toxicity values are expressed as (approximate) LD50 (median lethan dose) values for exposure by the oral and dermal routes.
Table 1: Acute toxicity hazard categories defining the respective categories.
| Exposure route | Danger | Warning | |||
| Category 1 | Category 2 | Category 3 | Category 4 | No classification | |
| Oral (mg/kg bw) | LD50≤ 5 | 5 < LD50 ≤ 50 | 50 < LD50 ≤ 300 | 300 < LD50 ≤ 2000 | LD50 > 2000 |
Based on the available studies, the substance is not classified for acute oral toxicity
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
