Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Phototransformation in air
The stability of trimethyl benzene-1,2,4-tricarboxylate in the atmosphere was calculated using the computer program AOPWIN (v 1.92). It is predicted that the substance will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals. The half-life for this reaction in air is estimated to be 23.0 days.
The overall degradation rate constant with OH radicals is estimated to be equal to 6.025E-8 cm3/(molecule-day).
Hydrolysys
In accordance with REACH Regulation 1907/2006, Annex VIII, Column 2, section 9.2.1.1, hydrolysis as a function of pH does not need to be determined as the substance can be regarded as readily biodegradable.
Biodegradation
Biodegradation: Significantly degraded but not readily biodegradable.
Bioaccumulation
In accordance with REACH Regulation 1907/2006, Annex IX (9.3.2), Column 2, a study of bioaccumulation need not be conducted because the substance has a low potential (based on a log Kow <3) for bioaccumulation.
Adsorption / desorption
The value of Koc is estimated to be 147 L/Kg, as from the OPERA (Q)SAR application.
According to the McCall classification scheme, this means that the above substance is highly mobile (50 < Koc < 150) on soil.
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.
