Description of key information

Additional information

HFC 227ea is a stable molecule in water. Abiotic hydrolysis or phototransformation in water are not considered significant degradation pathways, due to the absence of hydrolysable groups and to the very high volatility of the molecule.

In the atmosphere, HFC 227ea is subject to hydroxyl radical-mediated photodegradation in the troposphere, resulting in a calculated global atmospheric lifetime of 33 years.

Due to the absence of direct or indirect exposure to these compartments, the stability of HFC227ea in soil and sediment is to be considered as not relevant.
