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

In the assessment of magnesium 2-ethylhexanoate, read-across to the assessment entities soluble magnesium substances and 2-ethylhexanoic acid is applied since the ions of magnesium 2-ethylhexanoate determine its fate and toxicity in the environment. The potential for acute toxicity of magnesium to aquatic invertebrates is low based on EC50 values for Daphnia magna and Daphnia dubia being above the OECD 202 test limit of 100 mg/L and the fact that magnesium is added to standard test media. Based on available data from three studies, the lowest EC50 amounts to 85.4 mg/L 2-ethylhexanoate (48-h). Thus, magnesium 2-ethylhexanoate has some potential for short-term toxicity to aquatic invertebrates.
