Description of key information
Not applicable.
Key value for chemical safety assessment
Additional information
According to ECHA's "Guidance on information requirements and chemical safety assessment, Chapter R.7a: Endpoint specific guidance", viscosity is relevant to liquid substances only.
The test substance is a solid, thus no study is run.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
