Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- DBMC
- Type of composition:
- legal entity composition of the substance
- State / form:
- solid: particulate/powder
- Reference substance:
- DBMC
- PBT status:
- the substance is not PBT / vPvB
- Justification:
DBMC is considered to be persistent and fulfils the criteria for toxicity according to Annex XIII of Regulation 1907/2006EC, but since DBMC does neither meet all three criteria for a classification as persistent and bioaccumulative and toxic nor all two criteria as very persistent and very bioaccumulative, DBMC is not considered to be a PBT- or vPvB-substance.
- Likely routes of exposure:
Persistence Assessment
Taking into account that 6,6’-Di-tert-butyl-2,2’-methylenedi-p-cresol (DBMC) was not readily biodegradable in an OECD compliant ready-biodegradability test and hydrolysis is not a significant degradation process, DBMC is considered to be persistent according to screening criteria.
Bioaccumulation Assessment
DBMC has a measured bioaccumulation factor of 840. The value is well below the threshold (> 2000 L/kg PBT-criteria and > 5000 L/kg vPvB-criteria) for bioaccumulation. Therefore, DBMC is not considered to be bioaccumulative.
Toxicity Assessment
DMBC is neither included in Annex I to the Dangerous Substances Directive (67/548/EC) nor in Annex VI, Table 3.2 to the CLP-Regulation ((EC) No 1272/2008). Based on the available toxicity and ecotoxicity data and considering the provisions of the Dangerous Substances Directive (67/548/EEC) and of the CLP-Regulation ((EC) No 1272/2008), classification as a Cat. 2 reprotoxic (H361 fertility) under CLP is proposed. Thus DBMC fulfils the criteria for toxicity according to Annex XIII of Regulation 1907/2006/EC.
Conclusion:
DMBC is neither PBT nor vBvP.
Reference
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.
