Link to relevant study record(s)
- Endpoint:
- appearance / physical state / colour
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 20 March 2003
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: The study was performed to a good standard and in line with GLP, with a good level of reporting sufficient to assess the reliability of the results.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Visual and organoleptic evaluations were made on the physical state, colour and odour of the test material.
- GLP compliance:
- yes
- Physical state at 20°C and 1013 hPa:
- solid
- Form:
- powder
- Colour:
- White
- Odour:
- odourless
- Substance type:
- organic
- Conclusions:
- The test material was described as a white, odourless fine powder when observed at 25 °C. The study is considered to be reliable, relevant and adequate for risk assessment purposes.
- Executive summary:
Visual and organoleptic evaluations were made on the physical state, colour and odour of the test material. The test material was described as a white, odourless fine powder when observed at 25 °C.

Additional information
Visual and organoleptic evaluations were made on the physical state, colour and odour of the test material in two studies performed with pure and technical intermediates. The test material was described as a yellowish, odourless powder (technical intermediate) or a white, odourless fine powder (pure intermediate) when observed at 25 °C.
The study investigating the physical properties of the pure intermediate was selected as the key study for this endpoint as the most representative sample of the registered substance. Both studies were performed in line with good scientific principles. Both reports were GLP compliant and reported to a high standard. As such both studies were assigned a reliability score of Klimisch 2 and considered suitable for assessment.
The available data are considered to be complete and the description, white, odourless fine powder at 25 °C, was carried forward for risk assessment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
