Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Long-term toxicity testing with aquatic invertebrates is scientifically not justified.
Key value for chemical safety assessment
Additional information
For silicon orthophosphate no chronic aquatic toxicity data are available and consequently, no experimental NOEC value can be derived. However,due to the known inherent physico-chemical properties, absence of acute toxic effects in three trophic levels as well as the ubiquitous presence of silica/silicates and phosphates in the environment, there is no evidence of harmful long-term effects arising from exposure to synthetic silicon orthophosphate. Therefore, and with respect to animal welfare, long-term testing with aquatic invertebrates is scientifically not justified in accordance with Regulation (EC) 1907/2006, Column 2 of Annex IX, section 9.1.
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.
