Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
Link to relevant study record(s)
- Endpoint:
- appearance / physical state / colour
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 23 April 2012 - 29 June 2012
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- A desctiption of the test material was included as part of a study conducted in line with standardised guidelines and under GLP conditions to determine the general phsyico-chemical properites of the substance. Observations were included to identify the substance used in the tests. Although the focus of the study is not an organoleptic evaluation of the substance, the observations are considered to be an accurate reflection of the test material.
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- The appearance and physical state of the test material was assessed via visual inspection as part of a GLP compliant study to determine its general physico-chemical properties.
- GLP compliance:
- yes (incl. QA statement)
- Physical state at 20°C and 1013 hPa:
- solid
- Key result
- Form:
- crystalline
- Colour:
- White
- Substance type:
- inorganic
- Conclusions:
- The test material was determined by visual inspection to be a white solid.
- Executive summary:
The appearance and physical state of the test material was assessed via visual inspection as part of a GLP compliant study to determine its general physico-chemical properties.
The test material was determined to be a white solid composed of fine crystals.

Additional information
As part of a series of studies conducted under GLP conditions to determine the general physico-chemical properties of the test material, the state of the substance was assessed by visual inspection. As the appearance, physical state and colour were not the main focuses of the study, the data was assigned a reliability score of 2 in accordance with the principles for assessing data quality described by Klimisch et al (1997).
The test material was determined to be a white solid composed of fine crystals.
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).
