- A single dose of undiluted test material (5g/kg) was administered orally to 5 male and 5 female fasted rats. Food and water was made available ad-lib immediately after dosing. The animals were observed for clinical signs and mortality at hourly intervals for the first 6 hours post dosing and
twice daily thereafter. Body weights were recorded prior to fasting, prior to dosing and at 7 and 14 days post dosing. At 14 days, all surviving animals were killed and subjected to a gross necropsy examination. - GLP compliance:

Any other information on results incl. tables
There were no deaths during the study. Clinical signs observed included: hypoactivity, yellow-stained anal area, hair loss in the urogenital region and swollen hind paws. All animals returned to normal by day 3 and had gained weight by day 7. At necropsy, there were no visible lesions except in one female in which the spleen was cystic, mottled red and tan and had a rough surface. In this animal the pancreas adhered to the entire surface of the spleen.
Applicant's summary and conclusion
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.
