Description of key information
Key value for chemical safety assessment
- Surface tension:
- 72.3
Additional information
The key value for surface tension was chosen regarding the most reliable data: the final Risk Assessment Report for Diphenylamine. This value was confirmed by the results of the guideline study in the DAR 2007.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
