Description of key information
Trimellitic anhydride mono-chloride (TMAC) has estimated Koc values between 10 and 20.03.
Based on these values, the substance is expected to have a low tendency to adsorb to soils and sediments.
Additional information
Adsorption / desorption
(Q)SAR-modelled adsorption coefficient (Koc) values for trimellitic anhydride mono-chloride (TMAC) obtained with the KOCWIN v2.00 model of the US EPA range from ca. 10 to 20.03 L/kg.
But these values are not fully reliable (out of the applicability domain for one criteria).
Based on these values, TMAC is expected to be mobile and have a low tendency to adsorb to soils and sediments.
This result is given only for information, and must be taken with caution.
This QSAR prediction is not judged to be fully adequate to meet the data requirements for Regulation (EC) 1907/2006, Annex VIII, 9.3.1.,Adsorption/desorption screening.
It should be noted that the water exposure is not expected. In addition, the substance is readily biodegradable and hydrolyses rapidly. Therefore the estimation of the Koc value can be waived in the REACH context.
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.
