Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reliable measured biodegradation studies for p-tert-amylphenol are available for biodegradation in water and included in the dossier. However, no measured biodegradation in soil are available for p-tert-amylphenol.  The key and supporting study results for biodegradation in water indicate that the test substance biodegrades rapidly once microbes have had a chance to acclimate. All effluents related to the use of p-tert-amylphenol will be through industrial WWTP as the substance is used as an intermediate. Any release to wastewater treatment plant or soil from residual p-tert-amylphenol in resin is negligible.
