Description of key information
log Kow = 5.25 (calculated with KOWWIN v1.68)
log Kow = 4.6 (estimated from the single solubilities in n-octanol and in water)
Key value for chemical safety assessment
Additional information
Tridecylamine, branched and linear (CAS 86089 -17 -0) is a mixture composed of (predominantly) groups of isomers with chain lengths ranging from C11 to C14 and, to a minor content, of C10 alkylamines. The main fraction (68%) are C13 -amines, followed by the C12 - (16%), C11 - (C12%) and C14 -amines (3%).
The determination according to the HPLC method (OECD 117) yielded log Pow values in the range from log Pow 1.5 to 2.3 (at 23°C and pH = 7.0). These experimental results appear to be of limited value as surface tension properties of the molecule cannot be excluded (BASF AG, 2006; report no. 06Y43073: 29 mN/m at 20°C (concentration 1g/l))
There is a KOWWIN v1.68 calculation available (read-across from the structural analogue C16 substance 1 -tridecanamine; CAS 2869 -34 -3). Referring to the uncharged molecule the log Kow was calculated to be 5.25. The substance was within the applicability domain of the estimation model.
log Pow = 4.6 (estimated from the single solubilities in n-octanol and in water)
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
