EC number: 935-411-2
CAS number: -
A 48h- EL50 value higher than 100 mg/L loading rate (WAF) was appraised for the test item Ethoxylated bisphenol dimethacrylate according to OECD testing guideline 202.
To validate the use of the data generated for the Ethoxylated bisphenol A diacrylate (EC 701-362-9) to fill by read-across the other ecotoxicological endpoints, the toxicity of the test item Ethoxylated bisphenol A dimethacrylate (EC 935-411-2) was assessed on the most sensitive organism to ethoxylated bisphenol A diacrylate: aquatic invertebrate (Daphnia magna; 48h-EL50 = 6 mg/L).
The inhibition of mobility of the test item for a duration of 48 hours was measured according to the OECD testing guideline 202. Daphnia magna were exposed under semi-static conditions to a single nominal loading rate (WAF) of 100 mg/L. As no effects were observed, the loading rate causing 50% effect (EL50) was higher than the highest loading rate tested (100 mg/L WAF solution). This result was supported by another analogue (2 moles Ethoxylated bisphenol A dimethacrylate, EC 939-702-5) for which no effects were also observed at the highest loading rate tested (48h-EL50 > 100 mg/L).
