Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The test gave a 72-h ErC50 value for effects on growth rate of 82 mg/l, a 72-h ErC10 of 42 mg/l and a NOEC of 13 mg/l. These results are below the reported water solubility value for TCPP of 1080 mg/l.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 82 mg/L
- EC10 or NOEC for freshwater algae:
- 42 mg/L
Additional information
The test with P. subcapitata fulfilled all the reliability criteria. The test gave a 72-h ErC50value for effects on growth rate of 82 mg/l, a 72-h ErC10of 42 mg/l and a NOEC of 13 mg/l. These results are below the reported water solubility value for TCPP of 1080 mg/l.
Estimated 96-hour EC50 and NOEC values of 1.8 and 1.4 mg/l have been derived for algae using an ECOSAR QSAR applicable to esters. The estimated values are lower than those obtained in the reported studies.Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
