Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Value used for CSA: IPA: logD = -2.34 at pH 7 (ACD Labs v11.0)

Due to the rapid hydrolysis of the test substance, data for the primary degradation product, isophthalic acid, is provided. At environmentally relevant pH, the degradation product will exist predominantly in its anionic form. The logD, apparent partition coefficient D for dissociative systems is a more appropriate description of the complex partitioning equilibria.
