Formulation Review

The formulation ingredients and percentages you provided are correct and add up to 100%.

Your mixing instructions are also correct for creating a water-in-oil emulsion using Water-Capsule™. The method of separating into a water phase and an oil phase, then adding the oil phase to the water phase all at once and stirring at low speed, is the recommended procedure for this type of formulation.

Water Phase: Distilled Water, Disodium EDTA, PowderCream, MatteSilica™, Light Cream Maker, Phenoxyethanol
Oil Phase: SPF Protect Ultra, LipidSoft Dry, Water-Capsule, Titanium nano

Mixing these phases as described should result in the desired cream texture.
