Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Date: 02.05.1990
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Remarks:
Research memorandum provided instead of a study report.
Qualifier:
according to guideline
Guideline:
ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
GLP compliance:
not specified
Type of method:
closed cup
Flash point apparatus:
Setaflash apparatus
Specific details on test material used for the study:
Test material was noted as Trigonox D-C50
Key result
Flash point:
43 °C
Remarks on result:
other: reported flashpoint is for the marketed product (50 % in isododecane)
Interpretation of results:
Category 3 (flammable liquids) based on GHS criteria
Remarks:
commercial product is Category 3, the neat substance is not classified based on literature and modeling results being > 60 oC
Conclusions:
The flashpoint of the marketed product (50 % in isododecane) is 43 °C. This is consistent with the reported flashpoint of the isododecane (45 °C).
Executive summary:

To investigate the safety aspects of 2,2-di-(tert-butylperoxy) butane, 50% in isododecane, a product safety investigation has been carried out. The flashpoint of the marketed product (50 % in isododecane) is 43 °C.  This is consistent with the reported flashpoint of the isododecane (45 °C).

Description of key information

The flashpoint of the neat organic peroxide is > 60 oC based on literature and modeling results. The marketed product (50 % in isododecane) has a flashpoint of 43 oC, consistent with that reported for the isododecane (45 oC).

Key value for chemical safety assessment

Flash point at 101 325 Pa:
43 °C
