Description of key information
Expert Judgement
If released into water, Dipotassium oxide/ Potassium oxide is not expected to adsorb to suspended solids and sediment based upon the estimated Koc value of 13.22 L/kg . Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant is 2.814E-023 atm-m3/mole (2.851E-018 Pa-m3/mole).
On this basis phototransformation in water is not expected .
Therefore testing for Phototransformation in water does not need to be performed.
Key value for chemical safety assessment
