Applicant's summary and conclusion
- Conclusions:
- The half-life of 11-aminoundecanoic acid in air due to indirect photolysis is estimated to be 4.3 h.
Therefore, 11-aminoundecanoic acid is not expected to be persistent in the atmospheric compartment. - Executive summary:
The AOP V 1.89 calculation model has been used to estimate the half-life of 11-aminoundecanoic acid in air due to indirect photolysis.
Considering a concentration of sensitiser of 1000000 molecule OH /cm³ , the half-life is estimated to be 4.3 h.
Therefore, 11-aminoundecanoic acid is not expected to be persistent in the atmospheric compartment.
