chilblains in malta? Doesn't it have to be cold to have chilblains?
I don't know what emulsifying ointment is... there are emulsifying WAXES... you could google either emulsifying waxes or ewax. These have a chemical that allow you to mix the wax with water without separation.
If you are just making an ointment, beeswax will be okay, if you are making a lotion, where you need to mix in some water, it will separate without an emulsifying agent.
