Endpoint summary
Administrative data
Description of key information
As presented under Section 1, the substance is a Reaction mass of three inorganic calcium salts (fluoride, sulfate, and carbonate, the last being also considered as inorganic, though it contains carbon).
Density, water solubility and granulometry experimental studies were conducted on the test substance. Some properties were derived from data on the constituents. Endpoints that were not relevant were waived.
The substance is a dense, white to gray blocks of granular solid with some powder formation during handling and storage, highly stable to temperature (high melting point), therefore with negligible volatility. Water solubility is driven by the less soluble constituent, and is expected to depend on loading rate and pH. No surface activity is anticipated.
The test substance is NOT classified as dangerous with regard to physical hazards, based on CLP criteria.
