Description of key information
For the terrestrial compartment two long term earthworm tests performed according OECD guideline 222 are available. One test was performed with oleyldiamine and one with oleyldiamine di-oleate. In both tests a NOEC for reproduction, mortality and biomass was found of 1000 mg test item/kg soil (dry weight). Because of the structural similarity of oleyldiamine mono-oleate with oleyldiamine and oleyldiamine di-oleate it is considered justified to use the test result as observed for oleyl diamine di-oleate also for the mono-oleate without correction for it MW difference.
Additional information
In contrary to the aquatic tests where results of the available acute toxicity tests of N-(Oleyl alkyl)- 1,3 -propanediamine mono-oleates and one with N-(Oleyl alkyl)- 1,3 -propanediamine di-oleates are not comparable because the test solutions were prepared differently (bulk approach applied to the di-oleates), results from terrestrial and benthic tests should be comparable and should allow read across. In soil and sediment both mono- and di-oleates are expected to dissociate completely because through sorption of the cationic groups the dissociation equilibrium will lean to the side of full dissociation and results from diamines, mono and di-oleates should be identical when corrected for difference in molecular weight (MW).
No short-term terrestrial test data is available for diamines or diamines salts
For both the diamines and N-(Oleyl alkyl)- 1,3 -propanediamine di-oleates, long term earthworm tests were performed according to OECD guideline 222 test with Eisenia fetida under GLP (reliabilty 1).
In both tests a 56d-NOEC (reproduction, mortality and body weight) of 1000 mg/kg dry weight was observed. Because the mono-oleate as structurally sililar substance, has its MW in between that of the diamine and diamine di-oleate it is considered justified to use the test result of the long term earthworm also for the mono-oleate without correction for it MW difference.
