Description of key information
log Pow >7.64
Key value for chemical safety assessment
Additional information
The log Pow of the substance fatty acids, C16-18 (even numbered) and C16-18unsatd. (even numbered), mono-, diesters with neopentyl glycol and di-, triesters with trimethylolpropane (CAS 85186 -92 -1) was determined by QSAR calculation with KOWWIN (v1.68) for the single components.
As the results for the two larger components exceed the applicability domain of the model, the value is given as log Pow >10 (C18:1 NPG di: log Pow = 17.05; C18:1 TMP tri: log Pow = 24.73).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
