Description of key information
Log Koc ≥ 3.78 (KOCWIN v2.00)
Key value for chemical safety assessment
Additional information
No experimental studies investigating the adsorption/desorption potential of 2-ethyl-2-(hydroxymethyl)-1,3-propanediyl dioleate (CAS 25111 -05-1) are available. Therefore, the log Koc values were calculated using KOCWIN v2.00 based on the Molecular Connectivity Index (MCI) (Müller, 2015). The model has no universally accepted definition of the model domain. Two out of three constituents are outside the log Kow range of the training set of the MCI model, the results should be taken with caution. The definite values of these two constituents may not be fully reliable. However, the C18 unsatd. fatty acid monoester component is within the training set of the model and indicates a potential for adsorption based on a log Koc of 3.78. This result is fully reliable. Since the log Koc increases with the length of the fatty acid chain, it can be assumed that the adsorption potential of 2-ethyl-2-(hydroxymethyl)-1,3-propanediyl dioleate is high. This was further confirmed by the calculations of the diester and trimester with log Koc values > 5. In conclusion, the model indicates a high potential of adsorption for 2-ethyl-2-(hydroxymethyl)-1,3-propanediyl dioleate.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
