Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The UV spectra of both o-Cresol and anisole do not show any significant absorption of light at or above wavelengths 290nm. Therefore, direct photolysis on sunlit soil surfaces may not be environmentally important due to lack of absorption of sunlight by the structurally similar Guaiacol.

Description of key information

Key value for chemical safety assessment

Additional information

Direct photolysis on sunlit soil surfaces may not be environmentally important process for guaiacol due to lack of absorption sunlight (HSDB, 2007).
