Description of key information
Additional information
The test material, reaction mass of trientine and trientine, mono- and di-propoxylated was shown to degrade by a pseudo-first order behaviour. Half-life times at 25°C and pH 4, pH 7 and pH 9 were determined to be >1 year. The test material is considered stable in water.
No biodegradation were observed in the inherent biodegradation (8 % biodegradation) and ready biodegradation (4 % biodegradation) test of the test material
Reaction mass of trientine and trientine, mono- and di-propoxylated is not biodgeradable in water.
The simulation test for the biodegradation in water and sediment was not performed in accordance with column 2 of REACh (Regulation (EC) No 1907/2006) Annex IX, the simulation testing on ultimate degradation in surface water, and sediment simulation testing (required in section 9.2.1.2, and 9.2.1.4) do not need to be conducted based on the findings of the Chemical Safety Assessment; the test material does not fulfill classification criteria according to the applicable regulations and does not fulfill the criteria for vPvB or PBT.
In accordance with column 2 of REACh (Regulation (EC) No 1907/2006) Annex IX, the soil simulation testing (required in section 9.2.1.3) does not need to be conducted as the chemical safety assessment according to Annex I does not indicate the need to investigate further biodegradation.
In accordance with column 2 of REACh (Regulation (EC) No 1907/2006) Annex IX, the simulation testing on ultimate degradation in surface water, and sediment simulation testing (required in section 9.2.1.2, and 9.2.1.4) do not need to be conducted based on the findings of the Chemical Safety Assessment; the test material does not fulfil classification criteria according to the applicable regulations and does not fulfil the criteria for vPvB or PBT.
No determination was possible according to Method C19 Adsorption Coefficient of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 121 of the OECD Guidelines for Testing of Chemicals, 22 January 2001, due to the following reason:
A preliminary assessment of the three main constituents of the test material indicated that all three would be at least partially ionized across the entire environmentally relevant pH range (pH 5 to 7). Therefore, it is anticipated that adsorption to the organic carbon content of soils and sediments will not be the dominant mechanism controlling the mobility of the test item in the environment. Adsorption of cationic species occurs primarily by an ion-exchange mechanism and thus depends on the cation-exchange capacity of the sorbent as well as a variety of other parameters (Boethling, R. S.1994. Environmental aspects of cationic surfactants.InJ. Cross and E. J. and Singer (ed.), Cationic Surfactants: Analytical and Biological Evaluation, vol. 53. Marcel Dekker, Inc., New York, USA.). Consequently, the true adsorption coefficient of each constituent will be significantly higher than any Kocvalues determined by the OECD 121 method and via any computer-based Kocestimation software.
Therefore, based on the expected high cation-exchange ability of the three main constituents, the test material is anticipated to be essentially immobile in the environment. For PNEC derivation the maximum value from reference substances in OECD 121 (Table 1: log Koc of 2.58 for 2,5-Dichloroaniline) is considered to be a conservative estimate and therefore this value was substituted into PNEC calculations as a conservative estimate.
