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.
