Description of key information
In accordance with Column 2 adaptation statement of REACH Annex VIII and IX, adsorption/desorption screening and further studies on adsorption/desorption, information requirements 9.3.1 and 9.3.3, may be omitted since the log Kow value for the substance is <3.0 and has low potential for adsorption (CSR section 1.3). (Q)SAR-modelled KOC values for dimethyl terephthalate (obtained with the KOCWIN v2.00 model of the US EPA) range from 30.96 to 109.3 L/kg.
Key value for chemical safety assessment
Additional information
(Q)SAR-modelled Koc values for dimethyl terephthalate (obtained with the KOCWIN v2.00 model of the US EPA) range from 30.96 to 109.3 L/kg. Based on these values, dimethyl terephthalate is classed as moderately mobile to mobile and is expected to have a low tendency to adsorb to soils and sediments.
The low Koc values modelled for dimethyl terephthalate also imply a low tendency to associate with sludge solids during the primary settlement and secondary biological stages of waste water treatment. The majority of the DMT load contained in a treatment plant influent load may therefore be expected partition to the aqueous phase and to be routed toward aerobic biological treatment.
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.
