Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- Boundary composition
- Type of composition:
- boundary composition of the substance
- State / form:
- liquid
- Reference substance:
- Boundary composition
- Reference substance:
- Boundary composition
- Reference substance:
- Boundary composition
- PBT status:
- the substance is PBT / vPvB
- Justification:
The registered substance contains concentration > 0.1 % of a PBT/ vPvB compound which is Dibenzyltoluene. According to the Echa Guidance R11 related to the PBT/vPvB assessment, in that case, the registered substance has also to be considered as a PBT/vPvB substance.
The information about Dibenzyltoluene is summarised below:
Dibenzyltoluene (called now Dibenzylbenzene, ar-methyl derivative) can be considered as persistent based on the assessment of two of the main compounds of the substance:
- The half-life of o,m DBT in an OECD 309 study, was determined as 56 days concluding that this compound fulfils the P criteria. The estimated BCF value for this compound is 10 280 L/kg wet-wt meaning that this compound is potentially very bioaccumulable.
- The half-life of o,o DTPM in an OECD 309 study, was determined as > 10,000 days concluding that this compound fulfils the vP criteria. The estimated BCF value for this compound is 8513 L/kg wet-wt meaning that this compound is potentially very bioaccumulable.
