- Remarks on result:
- no ignition on contact with air (not further specified)
- Remarks:
- corresponding to 'no' in migrated source record.
Pyrophoric liquids
- Test procedure:
- ignition time on contact with air
- Remarks:
- Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
- Remarks on result:
- no ignition on contact with air (not further specified)
- Remarks:
- corresponding to 'no' in migrated source record.

Applicant's summary and conclusion
- Interpretation of results:
- non flammable
- Remarks:
- Migrated information
- Conclusions:
- According to the experimental results, ursodeoxycholic acid is not a highly flammable substance.
- Executive summary:
Ursodeoxycholic acid did not ignite, but the solid sample melted when the Bunsen burner flame came close, developing blackish drops. The substance did not propagate combustion. According to the experimental results, ursodeoxycholic acid is not a highly flammable substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
