Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

No acute aquatic toxicity to fish of a calcium silicate [LL50(96 h) >1000 mg/L).

Key value for chemical safety assessment

Additional information

A loading of 1000 mg calcium silicate/L (as suspension) produced slightly increased mortality in fish under test conditions within 96 h of exposure (PPG 1971). It is assumed that the freshwater results are also applicable to marine life, i.e. no acute aquatic toxicity expected from exposure to synthetic amorphous calcium silicates (CS).
