Endpoint:
stability: thermal, sunlight, metals, other
Type of information:
not specified
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.
Reason / purpose:
reference to same study
Reason / purpose:
reference to other study
Principles of method if other than guideline:
The method used for the determination of the thermal stability is not reported.
GLP compliance:
not specified
Test substance thermally stable:
ambiguous
Operating temp.:
170 - 220 °C
Sublimation:
not determined
Transformation products:
not measured
Test substance stable to sunlight:
not determined
Test substance stable to metals / metal ions:
not determined

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.
