Doing the math here - and excluding the coating on those UV screen minerals - I see you have 10.0% emulsifier-builder to emulsify 1.0% oil. That alone is not going to work. This puppy wants to invert Big Time. You also did not divulge your presumably external water phase, so all hope is lost here; and what’s up with the citric acid?

@chemicalmatt i added citric acid at the end of the formula to decrease the PH, its above 7 .
