TPGDA is acutely harmful to aquatic invertebrates.
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.
