Description of key information
An experimental study on the NCS itself to determine the adsorption was technically not feasible due to the complex nature of the substance.
Nevertheless, some constituents of the NCS are known. For information, these constituents exhibit Koc values ranging from 3.89L/kg to 1550247.18 L/kg, estimated by the use of 3 different QSAR Methods. This corresponds to log Koc ranging from 0.59 to 5.19.
Because of the low concentration of these constituents in the NCS (unknown constituents representing 88 to 99.5% w/w according to the SIP), these koc values cannot be considered representative of the NCS itself and the constituent approach is not regarded as an acceptable method to be used for this substance.
Key value for chemical safety assessment
