Description of key information

Additional information

Stability

The hydrolysis of the test item (1,6-hexanediyl-bis(2-[2-{1-ethylpentyl}-3-oxazolidinyl]ethyl) carbamate) was investigated using HPLC-MS and GC-MS. Measurements revealed a fast hydrolysis of the test item. The hydrolysis degradation products of the test item were identified qualitatively. The first hydrolysis product was determined to be 2-ethylhexanal. The second hydrolysis degradation product was identified on the basis of its molecular weight. The second, more likely hydrolysis product, which is in good consistency with the experimentylly determined molecular weight, is 1,6 hexanediyl-bis-carbamic acid bis(N-hydroxyethyl-2-aminoethyl) ester.

Biodegradation

The test item was biodegraded 43 % at day 28 in the test using a closed respirometer. The test item was considered inherently biodegradable.

Bioaccumulation

Direct and indirect exposure of the test item to water is highly unlikely. It can be assumed that upon contact with water and organic matter, the test item undergoes rapid degradation (hydrolysis) resulting in the formation of respective degradation products. Furthermore, the test item is considered to be inherently biodegradable. Therefore, the test item was considered to have no bioaccumulation potential.

Transport and distribution

Due to rapid decomposition (hydrolysis) of the test substance upon contact with water, measurement of the adsorption behaviour of the test substance was technically not feasible.
