HÄRTER VERSUCHSPRODUKT LS 2959E; HÄRTER VP LS 2959E
The hydrolysis of the test item
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)
The test item was biodegraded 43 % at day 28
in the test using a closed respirometer. The test item was considered
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
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.
