The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Additional information

When biodegradation of methylal is observed, this phenomenon is very weak and observed at low concentration in aerobic conditions. However, due to its high volatility, biodegradation of methylal has to be fast to be effective. Adaptation of micoorganisms to methylal is possible but is random and can disappear quickly.

No biodegradation of methylal was observed in anaerobic conditions, reflecting sediment conditions.

At more, due to its high volatility and Koc value, methylal is not expected to adsorb to soil but to be very mobile. Biodegradation in soil is supposed to be very marginal.

Methylal biodegradation in soil, water and sediment is very poor when occured.
