Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
In column 2 (9.4 Effects on terrestrial organisms) of Annex IX, REACH Regulation (EC) No 1907/2006, it is laid down that studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely.
Direct and indirect exposure of soil is considered unlikely to occur from the manufacture and use of o-tert-butylphenol. The substance is not supposed to be applied to soil, therefore direct exposure to soil organisms is not expected. Reliable biodegradation study results indicate that the substance is considered inherently biodegradable and it can be assumed that o-tert-butylphenol will be biodegraded within the STP process and unlikely to be transferred to the soil compartment via sewage sludge. Any release to wastewater treatment plants or soil from residual o-tert-butylphenol in resin is negligible.
The low adsorption coefficient of Log Koc 2.98 and the low bioconcentration factor (BCF = 78 from Chemical Evaluation and Research Institute Japan, 2008) indicate o-tert-butylphenol has a low potential for adsorption to soil or sediment and is unlikely to accumulate through the terrestrial ecosystem; indirect exposure to terrestrial organisms is considered unlikely. Therefore, no tests on terrestrial organisms are provided.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
