Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Additional information

Acute and chronic aquatic toxicity data for 2 of 3 trophic levels (marine & freshwater) are available for the read across substance THPS:

Algae: EC50 = 0.16 mg/L - 0.652 mg/l; NOEC = 0.063 mg/L

Invertebrate: LC50 = 0.6 mg/l - 19.4 mg/L; NOEC = 0.032 mg/L

The chronic toxicity to fish is scientifically unjustified for assessment because the acute toxicity to fish LC 50 = 72 mg/L-93 mg/l shows the most insensitive endpoint of all three trophic levels.
