Description of key information
According to Annex IX Section 9.4.3 of REACH Regulation 1907/2006 a short term toxicity study in plants is required. The substance consists of inorganic hydrated magnesium silicate, which when released into the environment will combine indistinguishably with the soil or sediment due to the similarity with inorganic soil/sediment matter and will be subjected to natural processes under environmental conditions (cation exchange, dissolution, sedimentation). It is therefore considered to be essentially a fraction of soil already. For this reason it is considered that the performance of short term toxicity tests on plants is not scientifically justified.
Key value for chemical safety assessment
Additional information
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.
