Any other information on results incl. tables
Preliminary Study (Screening Test)
The test item (4-carboxybutyl)triphenylphosphonium bromide (CBT)
was not flammable within 2 minutes by the flame of a butane gas burner
within the ignition zone (the first 50 mm of the formed test item). When
the white test item was directly exposed to the hot burner flame, it
melted, turned light brown, brown to black and carbonized. Blistering,
slight flying sparks and significant smoke development was observed. In
the burner flame the test item burned with an orange flame. After
cooling down, the test item appeared as a black, carbon-like melt.
Applicant's summary and conclusion
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- The test item (4-carboxybutyl)triphenylphosphonium bromide (CBT) is a ‘Not readily combustible solid of Division 4.1’ according to test guideline UN Test N.1., Section 33.1, UN -MTC (2015) and
‘not classified as a flammable solid‘ according to Regulation (EC) 1272/2008 (CLP).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
