The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Based on the predicted high logPow (~11.76) and the low water solubility of the substance (5.2 µg/L at 25°C/pH 6) test on acute aquatic toxicity is considered not to be required in accordance to regulation (EC) 1272/2006 annex VII column II. However, an acute fish test using a vehicle for preparation of test solution was initiated. No effects within the water solubility were observed. The calculated (geometric mean measured concentration) LC50 is >0.1 mg/L.

Furthermore, for risk assessment purposes a limit test (saturated concentration) on chronic toxicity reproduction study on daphnia magna was performed. No toxicity on reproduction of Daphnia magna  was observed in a saturated solution (concentration of 5 µg/L, indicating that any effect concentration, including the EC10, is higher than the measured water solubility of the SymMollient S (water solubility: 3.5 µg/L hexadecyl nonanoate, 1.7 µg/L octadecyl nonanoate). Thus, only an unbounded NOEC value (5 µg/L) could be derived from the chronic toxicity test with Daphnia.
