Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The adsorption of 14C-2,6 -DTBP was tested in batch equilibrium studies using three sediment types (EPA-5, EPA-8, and EPA15). 14C-2,6 -DTBP was shown to be stable during the 112 hour equilibration period, as determined by high performance liquid chromatographic (HPLC) analysis of the adsorption supernatant from a test replicate. The results indicated that the adsorption characteristics were similar among the three sediment types tested. The adsorption constants based upon the organic carbon content ranged from 2570 to 6960 with a mean value of 4493 l/kg. There was little apparent correlation of adsorption constant with sediment texture, organic matter, cation exchange capacity or pH.

Using the MackayFugacity Based Environmental Equilibrium Partitioning Model Level III v 2.70, 2,6-di-tert-butylphenol can be expected to distributed as follows in the environment:-

  • Fraction of emission directed to air – 0.0171%
  • Fraction of emission directed to water – 2.45%
  • Fraction of emission directed to soil – 70.3%
  • Fraction of emission directed to sediment – 27.25%
