- Specific details on test material used for the study:
- Name: Pentaerythritol tetrabenzoate
Appearance: off-white solid
Composition: Pentaerythritol tetrabenzoate >96%
CAS No.: 4196-86-5
EINECS-No.: 224-079-8
Molecular formula: C33H28O8
Molecular weight: 552.576 g/mol
Purity: >96%
Homogeneity: homogeneous
Expiry date: Nov. 2018
Storage: Room Temperature (20 ± 5°C) - Key result
- Test procedure:
- burning rate test: preliminary screening test
- Remarks:
- The test item melted into a clear liquid. No signs of ignition occurred within two minutes.
- Remarks on result:
- other: The test item melted into a clear liquid. No signs of ignition occurred within two minutes.
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- No ignition was observed throughout the course of the test. The test item Pentaerythritol tetrabenzoate should be considered as not highly flammable (for EU regulations) and as non-flammable solid (for UN regulations), No observations were made which might cause doubts concerning the validity of the study outcome.
- Executive summary:
In the current study, the flammability of Pentaerythritol tetrabenzoate following EU-Method A.10 and UN N.1 was determined.
First, a safety test was performed. A small amount of the test item was heated on a magnesia groove with a gas burner in order to derive safety precautions. The test item melted into a clear liquid. The liquid burned with an orange flame. In the preliminary screening test following the EU and UN method, the test item was heated with the flame of a teclu burner. The test item melted into a clear liquid. No signs of ignition occurred within two minutes. Therefore, the test item Pentaerythritol tetrabenzoate should be considered as
- not highly flammable (for EU regulations)
- non-flammable solid (for UN regulations)
