Description of key information

Degradation rate constant with OH radicals: 79.1097 E-12 cm³/molecules-sec (Chemservice S.A., 2010)

Key value for chemical safety assessment

Half-life in air:
0.203 d

Additional information

Concerning phototransformation in air no experimental data for N-methylethanolamine is available. Estimated data is based on a calculation with the US-EPA computer program EPI-WIN (AOPWINv1.92; Chemservice S.A., 2010). The substance is neither suspected to undergo ozone nor nitrate radical reactions. The gas-phase reaction constant is regarded as 79.1097 E-12 cm³/molecules*sec and a half-life of 0.203 days (around 5 hours) is calculated.
