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

Fathead minnows, Pimphales promelas, were exposed to five concentrations of Phosflex TXP under flow-through conditions for 96 hours. The 96 hour LC50 value was >1119 µg/L, the highest concentration measured. The 96-hour no mortality concentration and 96 hour NOEC were both 1119 µg/L.

No toxicity at the limit of solubility in water was therefore noted.
