Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

Description of key information

As per read-across from EC 270-608-0 and EC 283-392-8, acute aquatic toxicity was determined under OECD 203 in two independent studies: anno 2005 in freshwater (rainbow trout, 96 h nominal LC50=4.5 mg/L) and anno 1986 in saltwater (sheepshead minnow, 96 h nominal LC50=46 mg/L). 

Key value for chemical safety assessment

Additional information

Read-across from other, structurally closely related ZDDPs is justified because of structural similarity and analogy of properties and effects.
