Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The potential of aspartic acid, N,N'-[methylenebis(2-methyl-4,1-cyclohexanediyl)]bis-, 1,1',4,4'-tetraethyl ester to sorb on soil or sediment was determined according to EU-Method C.19 (HPLC-Method) yielding a logKoc between 4.2 and 5.1 (Bayer AG, 2003). The sorption coefficient was determined at pH 6 and pH 8 showing that the sorption behaviour does not depend on the prevailing pH.
According to the classification of Swann et al. (1983), aspartic acid, N,N'-[methylenebis(2-methyl-4,1-cyclohexanediyl)]bis-, 1,1',4,4'-tetraethyl ester has a high potential to sorb on soil.
Aspartic acid, N,N'-[methylenebis(2-methyl-4,1-cyclohexanediyl)]bis-, 1,1',4,4'-tetraethyl ester is characterised by a calculated Henry Law Constant of 0.24 Pa*m³/mol (Currenta, 2009b). According to Thomas, cited in the "Handbook of Chemical property Estimation Methods" (Lyman, 1980), the substance tends to partition in water and volatilisation rates are controlled by the slow diffusion through the air. Therefore, the substance has to be scored as being slightly volatile from water.
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.
