Description of key information
Additional information
According to the EPIWIN calculation Amides, C16 and C18-C20 (even numbered, unsaturated), N,N’-ethylenebis will be mainly distributed to the soil compartment. The substance will not tend to evaporate from the water surface, based on its Henry’s Law Constant ranging from 0.00487 - 0.0363 Pa m3/mol. Moreover, the substance has a high potential for adsorption to soil and sediment particles based on its log Koc of > 5.63.
This result is supported by the SIDS Initial Assessment Report (2006) for the structural analogue substance N-(2-Octadecanoylaminoethyl) octadecanamide which will be mainly distributed among soil (76.9%) and sediment (21.5%) compartments when released to the air; among sediment (97.4%) and water (2.6%) if released to the water; almost exclusively to the soil (99%) if released in this compartment, and among sediment (68.1%), soil (30%) and water (1.9%) when simultaneous release to air, soil and water occurs. The substance will not tend to evaporate from the water surface, according to its Henry’s Law Constant value 0.0151 Pa m3/mol. Furthermore, the calculated log Koc values of 8.6 and 8.91 indicate its potential for adsorption.
