Additional information

Concerning transport and distribution in the environment of 2 -dimethylaminoethanol no experimental data are available. Regarding the substance specific soil adsorption coefficient and Henry´s Law Constant scientifically accepted calculation methods (US-EPA computer program EPIWIN) were used (Chemservice S.A., 2010, revised 2019). KOCWINv2.00 utilizes two different models to calculate the soil adsorption coefficient: MCI Estimation Method and the traditional method. The MCI method is taken more seriously into account. Therefore, this result (Koc = 1.224) is taken as key value for the chemical safety assessment. HENRYWINv3.20 also uses two different models to predict the Henry´s Law constant for the desired chemical. For 2 -dimethylaminoethanol the Group Method as well as the Bond Method give the same value of 0.00018 Pa m³/mol at 25 °C. No further information regarding transport and distribution are required under REACH.
