Stevia sweetener in lip balm

[A Random Phrase]

This one brand has these ingredients:
Olive oil, substainable palm oil, beeswax, coconut oil, castor seed oil, stevia, aroma, mica

i've looked it up and in this case is the palm oil working as an emulsifier ?

But there are three other brands that don't seem to list any:

1- Beeswax, Shea butter, Coconut oil, Olive oil, Vitamin E, Sweet Almond oil, Stevia, Flavor oils
2 - Coconut oil, Beeswax, Flavor, Cocoa Butter, Essentiel oil, Shea butter, Vitamin E, Stevia
3 - Beeswax, Olive oil, Coconut oil, flavor oil, Stevia

Is it possible that you don't need to add the emulsifier to the list of ingredients ? Or maybe they just buy a sweetener like one dmcgee5034 mentioned, so no need to add more then just "stevia" in the ingredient list

The ingredients you shared have zero water, so the original question probably doesn't apply. But your answer definitely applies to the question I had ("Is water really necessary for lip balm?"). Thank you for that.
