Description of key information

A log POW of 2.21 (as intensity weighted average) is taken forward for hazard and risk assessment.

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
25 °C

Additional information

The partition coefficient of MonoFA_TETA_PAA_BADGE_BGE_Adduct was determined using the HPLC method in accordance with OECD guideline 117 and EC 92/69 method A8. The results are shown below:

Peak Mean LogPow

Peak 1 < 0.30

Peak 2 0.51

Peak 3 0.85

Peak 4 1.02

Peak 5 1.52

Peak 6 2.72

Peak 7 2.85

Peak 8 3.02

Peak 9 3.47

Peak 10 3.71

Peak 11 4.52

Peak 12 4.85

Considering the mean intensity of peaks and mean retention times a weighted average logPOW of 2.21 may be derived in order to assess bioaccumulative potential, given the fact that only 2 minor peaks, associated with oligomeric or polymeric properties of high molecular weight, were seen.
