Description of key information
A waste water treatment simulation test was performed with Amines, N-C16-18-alkyl (evennumbered) propane-1,3-diamine (CAS 133779-11-0). 99.4% removal was observed using specific chemical analyses (LCMS/MS) of the effluent during day 56 to 60 (n=5). Besides to that the sorption to sludge was measured and this accounted for 4.1% of the total removal which means that 95.3% is removed by biodegradation. Based on the ready biodegradability of all diamines (C10-18) and the fact that the simulation test has been performed with the diamine with the lowest bioavailability, it is considered justified to use the same results for the other more bioavailable diamines as for these a higher total removal and lower removal via sorption are anticipated.
Key value for chemical safety assessment
Additional information
A waste water treatment simulation test was performed with N-hydrogenated C16-18-alkyl-(evennumbered) propane-1,3-diamine (New CAS 133779 -11 -0 / Old CAS 68603-64-5). 99.4% removal was observed using specific chemical analyses (LCMS/MS) of the effluent during day 56 to 60 (n=5). Besides to that the sorption to sludge was measured and this accounted for 4.1% of the total removal which means that 95.3% is removed by biodegradation.
In conclusion, the CAS test demonstrates that hydrogenated N-C16-18-alkyl-(evennumbered)-1,3-diaminopropane will be biodegraded almost completely in a conventional biological wastewater treatment plant.
Similarly to diamines, Amines, N-(C16-18 and C18-unsatd. alkyl)trimethylenedi-, diacetates has been demonstrated to be readily biodegradable indicating that the presence of acetates has no influence on the degradability of this surfactant. In addition, diamines and the diamine acetate have a similar sorption and evaporation potential. Therefore, it is considered justified to use the STP result obtained with Diamine C16-18, C18-saturated-1,3-diaminopropane for read-across to Amines, N-(C16-18 and C18-unsatd. alkyl)trimethylenedi-, diacetates. For more details, see the read-across justification document ("Justification in support of cross-reading from diamines to diamine acetates").
