Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to the classification scheme of Swann et al. (1983), TMQ has a high adsorption potential in soil/sludge with the adsorption coefficient (log Koc) mostly above 4.09. TMQ is essentially non-volatile with the estimated Henry's law constant in the range of 2.8*10-9 to 3.0*10-5 Pa*m3/mol at ambient temperature using TMQ-dimer and trimer as typical compositions. As a mixture of oligomer derivatives of 1,2-Dihydro-2,2,4-trimethylquinoline with diverse physico-chemical properties, generic distribution is hardly to be modeled. However, considering the low water solubility observed (<3.2 mg/l at 25°C and pH 9), the low vapour pressure (<< 1 Pa), and relatively high Log Pow (5.8 in average) and Log Koc (mostly above 4.09), the TMQ released into environment is expected to be mostly found in sediment and soil compartment.
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.
