Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
There are no experimental data on environmental distribution ofReaction mass of 2,6-di-tert-butyl-p-cresol, 4,6-di-tert-butyl-o-cresol and 2,6-di-tert-butylphenol.
Reaction mass of 2,6-di-tert-butyl-p-cresol, 4,6-di-tert-butyl-o-cresol and 2,6-di-tert-butylphenolis a solid, poor water soluble substance with low vapour pressure.
QSAR modeling predicts that the substance components will volatize slowly from surface water with estimated TD50 = 11 days (river) and 127 days (lake).
Once in air,Reaction mass of 2,6-di-tert-butyl-p-cresol, 4,6-di-tert-butyl-o-cresol and 2,6-di-tert-butylphenol componentswill react with hydroxyl radicals with half-life of 7 hour.
The value for soil organic carbon-water partition coefficient (logKoc = 3.81 -4.34) suggests thatReaction mass of 2,6-di-tert-butyl-p-cresol, 4,6-di-tert-butyl-o-cresol and 2,6-di-tert-butylphenolhas some potential to adsorb onto soil and sediment and, therefore, it is not likely to contaminate groundwater.
The data on environmental distribution ofReaction mass of 2,6-di-tert-butyl-p-cresol, 4,6-di-tert-butyl-o-cresol and 2,6-di-tert-butylphenolobtained from the level III fugacity model confirms that this substance does not degrade fast and depending on various emission scenarios, will be in water, soil and sediment.
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.
