Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

Additional information


No test on hydrolysis is available. However, m-cresol is classified as readily biodegradable. Therefore no test is required according to REACH Regulation, Annex VIII, column 2. With regard to its chemical structure hydrolysis is not expected to be a relevant fate process.

Indirect photolysis in the atmosphere

In the atmosphere, m-cresol will react with photochemically produced hydroxyl-radicals. In his critical review Atkinson recommended values for the reaction constant kOH at room temperature of 6.4 x 10-11 cm3 x molecule-per second. Based on a tropospheric OH radical concentration of 5 x 10+5 molecules per cm3 a corresponding half-life of 6.0 h can be calculated.
