hmm can you share how much Tickener you are using? Sometimes if you have to mutch emulsifier and thickener the water is squeezed out of the structure.
sorry don’t have a better idea from what you wrote. to give better help we would need at least general levels of oil phase/water Phase/thickener/emulsifier ratios.
another thing can be the ph of your formulation maybe it is to low for the emulsifier and xanthan gum doesn’t like ph that is to low as well.
