Description of key information
Relative density is 1.3497 (EEC method A.3. and OECD Guideline 109, pycnometer method, GLP)
Key value for chemical safety assessment
- Relative density at 20C:
- 1.35
Additional information
In a GLP study conducted according to Directive 92/69/EEC, A.3. and OECD Guideline 109 (1995) (pycnometer method) the relative density was determined to be 1.3497.
