Description of key information

The log Kow for Tetramine diC16-18 was calculated to be >12.95 using several Kow estimation models.

Key value for chemical safety assessment

Log Kow (Log Pow):

Additional information

The calculated Log Kowvalues for Tetramine diC16 -18 of 15.6 using KOWWIN and 12.95 using ALOGPS 2.1. 

Despite of the importance of the log Kow for CSA and C&L no measured log Kow value was derived for Tetramine diC16 -18 because of the extreme low water solubility and high predicted log Kow. For very hydrophobic substances there are too many experimental difficulties to obtain values with sufficient certainty.

For substances with a calculated log Kow higher than 10 the REACH PBT guidance R.11 states that the substances BCF is probably lower than 2000. This is confirmed by the low calculated log BCF values.
