Applicant's summary and conclusion
- Conclusions:
- Light yellowish crystalline powder at 20°C and 101.3 kPa
- Executive summary:
The physical state of the test substance was performed by visual examination. The physical state of the test substance at 20°C and 101.3 kPa was determined to be a light yellowish crystalline powder. Microscopy examination showed the crystals to appear as needle-shaped crystals with a tendency to form agglomerates.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
