NO SYSTEMIC EFFECTS were found.
SKIN IRRITATION at the treatment site was found in ALL GROUPS. It was described as severe for high dose animals, moderate for middle dose animals, and slight for low dose animals. Two high dose animals died and two were sacrificed.
No treatment related effects were evident from the haematology, clinical chemistry and organ weight data
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.
