Applicant's summary and conclusion
- Conclusions:
- DIRECT PHOTOLYSIS in air
Monoglyme does not absorb light >290 nm (ozone band) and therefore a direct photolysis in air will not occur.
INDIRECT PHOTOLYSIS in air
OH radical induced indirect photolysis of Monoglyme can be estimated with US EPA AOPWIN Program estimating low degradation half-life of DT50 = 0.341 days (24-hr day, 1.5E6 OH/cm³). - Executive summary:
