Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
(Q)SAR-modelled KOC values for isophthalic acid (obtained with the KOCWIN v2.00 model of the US EPA) range from 11.86 to 79.24 L/kg. Based on these values, isophthalic acid is classed as moderately to very mobile and is expected to have a low tendency to adsorb to soils and sediments. KOC may be influenced by and vary significantly in response to pH. Under alkaline conditions, isophthalic acid will rapidly be converted to salts whose KOC may be expected to be lower (mobility higher) than that of the free acid.
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.
