1,3-Propanediamine, N-[3-((C11-14, C13-rich)oxy)propyl]- branched acetate

Endpoint summary

Additional information

Only one valid ready biodegradability test result for N-[3-(tridecyloxy)propyl]-1,3-propane diamine,branched monoacetate and N-[3-(tridecyloxy)propyl]-1,3-propane diamine branched is available because these substances are extremely toxic to micro-organisms. N-[3-(tridecyloxy)propyl]-1,3-propane diamine,branched monoacetate and N-[3-(tridecyloxy)propyl]-1,3-propane diamine branched did not cause a reduction in the endogenous respiration in the presence of 16 mg/L of humic acid. N-[3-(tridecyloxy)propyl]-1,3-propane diamine,branched monoacetate and N-[3-(tridecyloxy)propyl]-1,3-propane diamine branched was biodegraded 8% at day 28 in the Closed Bottle test. In the prolonged Closed Bottle test (enhanced biodegradability testing) a biodegradation percentage of 63 was achieved at day 60. Hence this substance should be classified as not persistent.

 

 

Table Summary of degradation rate constants in various (eco)systems based the biodegradability of N-[3-(tridecyloxy)propyl]-1,3-propane diamine, branched monoacetate and N-[3-(tridecyloxy)propyl]-1,3-propane diamine branched

(Eco)system	Method
Surface water (fresh)	TGD default value	<40 days half-life
Surface water (fresh) sediment	TGD default value	30000 days half-life
Marine water	TGD default value	<60 days half-life
Soils	TGD default value	30000 days half-life^a
Degradation in sewage treatment plants	Determined in bioreactors	99.8% removal primarily by biodegradation

^aHalf-life of the fraction dissolved in the water phase is expected to in the order of a few days.
