- Specific details on test material used for the study:
- TREATMENT OF TEST MATERIAL PRIOR TO TESTING
The test item was reduced by grinding using a mortar and dried in a desiccator under vacuum using silicagel as the drying agent at 19.9 ± 0.2°C in the dark for 48 hours. - Dynamic viscosity of test material:
- not applicable (substance is a solid)
- Key result
- Type:
- relative density
- Density:
- 1.04 other: dimensionless
- Temp.:
- 20 °C
- Remarks on result:
- other: D 20 /4
- Key result
- Type:
- density
- Density:
- 1.04 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The relative density D20/4 of the substance was determined to be 1.04.
- Executive summary:
The density of the substance was determined at 20°C using a gas comparison pycnometer in a GLP study according to EC A.3, OECD 109 and OPPTS 830.7300. The relative density D20/4 was determined in duplicate obtaining a mean value of 1.04.

- 1.04
Additional information
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.
