Description of key information

The adsorption coefficient (Koc) of trans-N1,N1,N4,N4-tetrakis(2-hydroxyethyl)-1,4-cyclohexanedicarboxamide on soil and on sewage sludge was determined in a GLP study with the HPLC method according to OECD TG 121 (2001) and EC method C. 19 (2008). The result was Koc = 0.500 (log Koc = -0.3008) for soil and Koc = 0.459 (log koc = -0.33807) for sewage sludge. This is "practically no adsorption potential" (Koc < 1) on the Blume scale.

Key value for chemical safety assessment

Koc at 20 °C:
0.5
