Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Terracess TF is an inorganic substance with very low water solubility. No adverse effects were found, other than effects in the aquatic tests at levels far above the water solubility of the test substance for two similar substances. All data available show a very low toxicity of the substance.
Toxicity to fish: The 96h-LC50 for fish exceeded the maximum solubility of the test substance in water at a loading rate of 100 mg/L. Therefore the weight of evidence shows that Terracess TF will not be toxic to fish.
Toxicity to aquatic invertebrates: The 48 hr EC50 for Daphnia magna exceeds the maximum solubility of the substance in water in studies on two similar substances. Therefore the weight of evidence shows that Terracess TF will not be toxic to Daphnia magna.
Toxicity to algae: Under the conditions of the present study with Selenastrum capricornutum exposed to TERRACESS L, the ErC50 was calculated to be above water solubility.
Toxicity to microorganisms: Under the conditions of test, Terracess L is not toxic to waste water (activated sludge) bacteria at a nominal concentration of 100 mg/L. The EC50 exceeded a loading rate of 100 mg/L.
All data available show a very low toxicity of Terracess TF.
Note: read across of Terracess L and Terracess P to Terracess TF for aquatic toxicity was accepted under NONS by the UK Environment Agency on 8th June 2005 (see the read across justification document for Ecotoxicity, section 13) on the basis that all three substances are inorganic oxides of titanium with a macromolecular structure rendering them insoluble and stable: Terracess TF: potassium titanium oxide, Terracess L: potassium lithium titanium oxide, Terracess P: potassium magnesium titanium oxide.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).
