Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Key value for chemical safety assessment
Additional information
The BUA assessment report has following statement:
"Within a period of 130 days, an air concentration of 420 mg/m³, inhaled by rats and guinea pigs 7 hours daily, 5 days per week, led to delayed weight gain of the male animals as opposed to the untreated control animals."
The quality of this information can not be assessed since the experimental details were not provided. The effect is not quantified and hence the meaning of "delayed weight gain" remains unclear. Therefore it is not clear if this information can be used for the further risk assessment.
Justification for classification or non-classification
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.
