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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Testing on the above endpoints gave the following results:
Acute toxicity: Oral.
- LD50: >2000 mg/kg
Acute toxicity: Dermal.
- LD50: >2000 mg/kg
Acute toxicity: Inhalation.
Not measured.
The test substance has a presumed very low vapour pressure and is a granular product, hence the potential for the generation of inhalable forms is low. In addition, production and use is done in a closed process without isolation of reaction products. The isolated product are dust free granules (non-dusty solid) and the use of the substance will not result in aerosols, particles or droplets of an inhalable size, so exposure to humans via the inhalatory route will be unlikely to occur. Dermal exposure is considered to be the appropriate route of exposure and has been assessed accordingly. No acute inhalation test was performed.
The following information is taken into account for any hazard / risk assessment:
Oral, inhalation and dermal acute toxicity are all considered.
Value used for CSA:
LD50 (oral): 2000 mg/kg bw
LD50 (dermal): 2000 mg/kg bw
Justification for classification or non-classification
The above studies have all been ranked reliability 1 according to the Klimish et al system. This ranking was deemed appropriate because the studies were conducted to GLP and in compliance with agreed protocols. Sufficient dose ranges and numbers are detailed; hence it is appropriate for use based on reliability and animal welfare grounds.
The above results triggered no classification under the Dangerous Substance Directive (67/548/EEC) and the CLP Regulation (EC No 1272/2008). No classification for acute effects is therefore required.
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.
