Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

According to its physico-chemical properties tetrahydro-4-methylphthalic anhydride (4-MTHPA) is not expected to be distributed into sediment. Hence, no information on effects on sediment –dwelling organisms is needed and the risk for this compartment is considered to be low.

Key value for chemical safety assessment

Additional information

Results of sediment tests are not available. However, in view of the negligible adsorption of tetrahydro-4 -methylphthalic anhydride (4-MTHPA) to sediment it can be assumed that in such tests the exposure through sediment pore water does not differ significantly from that to tetrahydromethylphthalic anhydride in the overlaying water and that hazards resulting from uptake of sediment can be excluded.
