Description of key information
Additional information
In total, two studies on the substance itself (EC 400-830-7) and two studies on EC 407-000-3 (structurally similar to the monoester component) are available.
According to the studies on the substance itself, degradation rates below 24% were determined. For the monoester form primary degradation of 57% to3-[3-tert-butyl-5-(2H-benzotriazol-2-yl)-4-hydroxyphenyl] propionic acid could be observed.
Two studies under aerobic and anaerobic conditions on a structural analogue of the monoester form (EC 407-000-3) revealed degradation to 3-[3-tert-butyl-5-(2H-benzotriazol-2-yl)-4-hydroxyphenyl] propionic acid followed by degradation to numerous minor fractions and incorporation of residues into the organic matter of the sediment. The DT50 values for 3-[3-tert-butyl-5-(2H-benzotriazol-2-yl)-4-hydroxyphenyl] propionic acid are 40 to 64 days. The mineralization was low.
In conclusion, EC 400-830-7 consists of a diester and a monoester form. The diester form did not show any potential to biodegrade in the test systems. It remained stable and unchanged. However, the monoester form was hydrolyzed to 3-[3-tert-butyl-5-(2H-benzotriazol-2-yl)-4-hydroxyphenyl] propionic acid. Under aerobic conditions this metabolite was shown to further degradeto numerous minor fractions and incorporation of residues into the organic matter of the sediment. TheDT50 values for3-[3-tert-butyl-5-(2H-benzotriazol-2-yl)-4-hydroxyphenyl]propionic acidare 40 to 64 days. The mineralization was low.
