Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

TAED

has a very low Log Kow of -0.1. As Log Koc is correlated with Log Kow, a low Log Kow corresponds to a low Log Koc. This low potential for sorption is supported by measured Koc values for 3 soils with Koc values between 43-91 L/kg (AISE HERA TAED, see PDF attached in Section 13). Estimation of Koc for TAED with the US EPA KOCWIN Version 2.00 results in 81 L/kg (MCI Method) and 7 L/kg (Kow QSAR).

DAED

has a very low Log Kow of -1.0. As Log Koc is correlated with Log Kow, a low Log Kow corresponds to a low Log Koc. This low potential for sorption is supported by a measured Koc of 25 L/kg (AISE HERA TAED, see PDF attached in Section 13). Estimation of Koc for DAED with the US EPA KOCWIN Version 2.00 results in 10 L/kg (MCI Method) and 2 L/kg (Kow QSAR).

 

HENRY’S LAW CONSTANT

TAED and DAED

The Henry’s Law constant can be calculated from vapour pressure and water solubility or estimated with e.g. with US EPA HENRYWIN program. Both methods demonstrate that TAED and DAED have a very low volatiliy e.g. 1.8 * E-11 Pa*m3/mole (TAED) and 7*E-10 Pa*m3/mole based on US EPA HENRYWIN.

 

DISTRIBUTION MODELLING

TAED and DAED

Due to the inherent properties of TAED and DAED e.g. low toxicity a classification according 1272/2008/EC Classification, Labelling and Packaging (CLP) is not warranted. Therefore no exposure nor a risk assessment has to be carried out for TAED and DAED. Information on exposure and risk can be found in AISE HERA TAED (see PDF attached in Section 13).
