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.
