Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Hydrolysis is not relevant due to poor solubility of the substance in water (WS < 0.05 mg/L)

Key value for chemical safety assessment

Additional information

No experimental studies investigating the abiotic hydrolysis of 1,2-Benzenedicarboxylic acid, di-C16-18-alkyl esters (CAS No. 90193-76-3) are available. However, in accordance with Annex VIII, column 2 (subsection of Regulation (EC) No. 1907/2006, testing for hydrolysis as a function of pH is not required since the substance is highly insoluble in water (< 0.05 mg/L). In addition, QSAR calculations (HYDROWIN v2.00) support the assumption that hydrolysis is a negligible degradation pathway for this substance, with DT50 values > 1 yr (at pH 7; Erler, 2013).
