Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Test(s) towards terrestrial organisms should be proposed by the registrant if the chemical safety assessment indicates the need to further investigate the effects on terrestrial organisms. Annex IX of Regulation 1907/2006 states that, in the absence of toxicity data for terrestrial organisms, the equilibrium partitioning method (EPM) may be applied to assess the hazard to terrestrial organisms. The results of the chemical safety assessment indicate that potential exposure would not be expected to result in an unacceptable level of risk for the terrestrial compartment. Therefore, no specific testing is required to assess the toxicity of the substance to terrestrial organisms.
Furthermore, there is no wide dispersive use as the chemical is only used in industrial processes. From industrial processes, in the unlikely case that tetrahydrophthalic anhydride (THPA) will reach sewage, the anhydride group, which represents the single reactive and toxic functional moiety, rapidly hydrolyses to the respective di-acid. Overall, it is expected that THPA will not be present in sewage sludge and will not therefore be distributed to soil via spreading of sewage onto agricultural land. Direct and indirect exposures of the terrestrial compartment is unlikely.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
