Description of key information

Additional information

The stability of the registered substance in the environment has been assessed for hydrolysis and phototransformation in water (photohydrolysis). The key values for these endpoints are presented below:

Hydrolysis: 15 years at 15ºC

Phototransformation in water (photohydrolysis): 53 days in roof sunlight (natural conditions - direct sunlight)

This information indicates that phototransformation is the main mode of abiotic degradation in the environment. Degradation products of phototransformation in water are bromoethanol which is then degraded to ethylene oxide. For hydrolysis the degradation products were characterised as ethylene, vinyl bromide, 1,2 -ethandithiol and ethylene glycol across all studies available.

The following modes of degradation are proposed for the abiotic degradation of the registered substance in water (derived by phototransformation and hydrolysis):
