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

The LC50 for propylene glycol phenyl ether is greater than 100 mg/L in Daphnia in the GLP study, as no effects were observed at the highest test concentration (BASF, 1997). The EC50 determined in a second study on Daphnia was determined at 370 mg/L (Dow, 1978). Since the results of both studies are consistent, the latter EC50 is selected as a key study for this endpoint.
