Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
The thermal stability of antioxidant MBP 5, which is chemically equivalent to DBMC, is cited in the report on ANTIOXIDANT MBP 5 from the Société Française D'Organo-Synthèse without indication of the method used, hence the information on the thermal stability is reliable with restrictions.

Good stability below 170 - 175 °C. Decomposition starts over 200 - 220 °C.

Conclusions:
Antioxidant MBP 5 shows good thermal stability below 170 - 175 °C, but decomposition starts over 200 - 220 °C.
Executive summary:

In the SFOS report it is indicated that Antioxidant MBP 5, which is chemically equivalent to DBMC, shows good thermal stability below 170 - 175 °C, but decomposition starts over 200 - 220 °C.

Description of key information

In the SFOS report it is indicated that Antioxidant MBP 5 (i.e. DBMC) shows good thermal stability below 170 - 175 °C, but that decomposition starts at temperatures above 200 - 220 °C.
