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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Adsorption / desorption
The soil adsorption was calculated with the computer program KOCWIN. This tool estimates the organic carbon-normalized sorption coefficient for soil (and also for sediment), which is designated as Koc. Two different models are used for this estimation: the Sabljic molecular connectivity (MCI) method as well as with the traditional method which is based on logPow.For the substance manganese chelate of sodium salt N-[1,2 dicarboxyethyl] D,L aspartic acid, the traditional method gives a logKoc of -2.808 L/kg and the MCI method reveals a value of logKoc of 1.000 L/kg as result. The MCI method is taken more seriously into account due to the fact, that it includes improved correction factors.
Henry´s Law Constant
Henry’s Law Constant was calculated manually (key information) and by the computer program EPIWIN/HENRYWIN v3.20 (supporting information).
According to ECHA REACH Guidance on information requirements and chemical safety assessment (Chapter R.16 - Environmental Exposure Estimation; version 2.1; October 2012), Henry's Law Constant amounts to 2.04 E-8 Pa*m3*mol-1 at 20 °C (Chemservice S.A., 2014c).
The software tool HENRYWIN calculated a Henry´s Law Constant of 8.748 E-17 Pa*m3*mol-1 for the substance (Chemservice S.A., 2014d). This value was estimated by the software tool using estimated values for the vapour pressure and the water solubility. Both calculation methods show that the substance has a negligible Henry's Law Constant.
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.
