Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
