I am making a Vitamin C serum using a specific formulation including water phase, oil phase (with Ascorbyl Tetraisopalmitate and Vitamin E), and a Sodium Polyacrylate/Polyisobutene emulsifier/thickener blend. I mixed the water and oil phases separately, then slowly added the oil phase to the water phase while stirring. However, the mixture separated into water and oil layers and the texture remained watery, not thickening into a serum. Is my mixing method correct, and what could be the reasons for the separation and lack of viscosity?
