Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
ABIOTIC DEGRADATION IN AIR
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).
ABIOTIC DEGRADATION IN WATER
HYDROLYSIS
The ether function of Monoglyme can only be cleaved under very acidic conditions. Under environmental conditions (pH 4 - 9) cleaveage is unlikly. This was confirmed by a hydrolysis test according to OECD 111 at pH 4, 7 and 9. No transformation was observed after 5 days at 50 deg. C.
DIRECT PHOTOLYSIS in water
Monoglyme does not absorb light >290 nm (ozone band) and therefore a direct photolysis in water will not occur.
INDIRECT PHOTOLYSIS in water
OH radical induced indirect photolysis of Monoglyme can be estimated with US EPA AOPWIN Program estimating low degradation half-life of 1 day (24-hr day, 0.5E6 OH/cm3). Therefore Monoglyme may also be degraded in water by indirect photolysis if sufficent OH radicals were available.
ABIOTIC DEGRADATION IN SOIL
DIRECT PHOTOLYSIS in soil
Monoglyme does not absorb light >290 nm (ozone band) and therefore a direct photolysis on soil surface will not occur.
INDIRECT PHOTOLYSIS in soil
OH radical induced indirect photolysis of Monoglyme can be estimated with US EPA AOPWIN Program estimating low degradation half-life of 1 day (24-hr day, 0.5E6 OH/cm3). Therefore Monoglyme may also be degraded in soil by indirect photolysis if sufficent OH radicals were available. Due to the low sorption of Monoglyme to sewage sludge exposure of soil can be neglected. Therefore this fate process plays a minor role only.
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.
