If this is the complete ingredients list then this is an anhydrous formulation NOT an emulsion. It does not have emulsifiers.

This looks to be an anhydrous formula which doesn’t need an emulsifier because there is no water. Emulsifiers create O/W emulsions. Hope this helps!

None of those is an emulsifier that I know of, except possibly the glycolic acid, of which I have no experience.

If there is water in the formula my best educated guess would be that the beeswax, stearic acid, and paraffin are keeping things “stable” by preventing the water from escaping, but it doesn’t appear to be a solid emulsion.

Sidenote: I always wondered how herbalist kept their salves together using only beeswax and/or cetyl alcohol? And those things last! )

Lanolin has emulsification properties. Perhaps triethanolamine has been omitted from the ingredients list and it is reacting with the stearic acid creating TEA stearate, an anionic emulsifier. (Ditto with sodium borate reacting with the beeswax).

If this “emulsion” is very viscous then due to stokes law it will take longer to separate than a thinner emulsion.
