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 chronic toxicity of magnesium to aquatic invertebrates is low based on a 21-day EC50 (reproduction) of 125 mg Mg/L and the fact that magnesium is added to standard test media. Chronic toxicity of 2-ethylhexanoate to Daphnia magna was assessed in an OECD 211 conform study, yielding an 21-d NOEC of 25 mg/L 2-ethylhexanoate as well as an 21d-EC50 of 75 mg/L, both endpoints being well above the respective OECD test limit of 10 mg/L. Thus, magnesium 2-ethylhexanoate has a very low potential for long-term toxicity to aquatic invertebrates.
