Additional information
No experimental studies investigating the phototransformation in air of ethylene diformate (CAS 629-15-2) are available.The vapour pressure reported for ethylene diformate, 172 Pa, indicates a potential of the substance for volatilization into air. Evaporation from the water phase into air is nevertheless not expected based on the low Henry’s Law constant (< 1 Pa m³/mole (HENRYWIN v3.20); Müller, 2011). However, if released into air, the substance is susceptible to indirect photodegradation by reaction with OH-radicals with a DT50 value of 104.74 h (AOPWIN v1.92; Müller, 2011). Therefore, significant accumulation in air and the subsequent transport to other environmental compartments is not anticipated. Furthermore, ethylene diformate is not listed in Annex I of Regulation (EC) 2037/2000 on substances that deplete the ozone layer and does not belong to the greenhouse gases listed in the Intergovernmental Panel on Climate Change (IPCC) IPCC/TEAP Special Report, 2005. This substance is thus of no concern for the air compartment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
