Additional information
Experimental data on toxicity of Tripropylenglykoldiacrylate (TPGDA, CAS 42978-66-5) to aquatic invertebrates are available.
As key study was performed conducted according to EU Method C2, using Daphnia magna as a test organism (BASF AG, 1988, rep. no.: 1/0671/2/88-0671/88). No vehicle was used in this study. The 48h EC50 was determined to be 89 mg/L, based on nominal test concentrations.
The test concentrations were not analytically verified. However, the test concentrations are assumed to be stable over the exposure period based on a sufficient water solubility, a low Henry's Law constant (see IUCLID Ch. 5.4.2) and a low adsorption potential (log Kow = 2.7, measured, see IUCLID Ch.4.7; Log Koc = 3, worst-case, estimated, see IUCLID Ch. 5.4.1).
It can be concluded that the substance is with high probability acutely harmful to aquatic invertebrates.
