Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
A weight of evidence approach was taken to address this data requirement. A multitude of sources were available listing the appearance, physical state and odour of the registered substance.
de Vogel (2004) and Waalkens-Berendsen (2004) both reported the substance as a white powder, Hooftman & de Wolf (2004) reported the substance as a colourless solid. These three sources were all observations of the test material identity in GLP studies investigating toxicological and ecotoxicological effects. No information pertaining to the method used for these observations are indicated in the report. The data was assigned a reliability score of 2 in accordance with the principles outlined in Klimisch (1997) for assessing data quality.
Information was also available in the following MSDS
WITCO (2000): colourless, odourless solid.
ACROS (2010): off-white odourless powder.
ALFA AESAR (2010): whitish powder
ARKEMA (2007): white powder with no characteristic odour.
GELEST (2003): white to off-white powder with a slight odour.
TCI (2010): white to almost white solid (crystal - powder)
No information regarding the performance of the observations was included in the summary. The information in these sources was presented only as a short abstract as part of a MSDS. A reliability score of 4 was therefore assigned, in accordance with the criteria for assigning data quality in line with the principles described by Klimisch (1997).
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.
