Key value for chemical safety assessment

Half-life in air:
10.7 h

Additional information

The hydroxyl radical induced photolysis of 2-aminoethanol in the atmosphere is estimated by the EPIWIN AOP Program (v1.92) to have a rate constant of 35.8449E-12 cm³/(molecule-sec). The corresponding estimated half-life of 2-aminoethanol is 10.74 hours assuming a hydroxyl radical concentration of 0.5E06 molecule/cm³. The substance is within the applicability of the model.
