Description of key information

A long-term toxicity test with Daphnia magna exposed to 2 methacrylic acid, monoester with propane-1,2-diol and conducted under GLPs, semi-static conditions, and following standard test guidelines (OECD 211), resulted in a NOEC for reproduction of 45.2 mg/L.

Key value for chemical safety assessment

Additional information

One long-term freshwater aquatic invertebrate study was available for methacrylic acid, monoester with propane-1,2-diol and considered reliable for assessment of this endpoint. The study was conducted with Daphnia magna and found to be of good quality and assigned a Klimisch score of one. The study was conducted for 21-days, under semi-static conditions, following OECD Test Guideline 211, and under GLPs. The study concluded the 21-day NOEC for reproduction was 45.2 mg/L and was considered the key parameter for this endpoint.
