Additional information
Acute Oral (Read-across from structurally similar substance)
The acute oral toxicity of the test material to rats was investigated under GLP conditions. The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).
The test material was administered at 10 g/kg by gavage to one group of ten rats (5 per sex) which were fasted for 18 hours prior to dosing. The rats were observed immediately, and at 1 and 4 hours after dosing and daily thereafter for clinical signs and mortality. Body weights were recorded initially and at the time of death. The surviving rats were sacrificed 14 days after dosing by CO2 inhalation and subjected to a gross necropsy.
No mortality was observed at a dose of 10 g/kg. There were no significant clinical signs seen at this dose level. All animals gained weight and no visible lesions were observed in the surviving animals upon terminal necropsy.
Under the conditions of this study the estimated acute oral LD50 for male and female rats treated with the test material was determined to be greater than 10.0 g/kg.
Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No. 1272/2008, the substance does not require classification with respect to acute 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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
