Seeking advice on formulating a tone-up body wash with acne treatment properties. Using a formula with Water, Soft Cream Maker, Sweet Almond Oil, Glycerin, Methyl Gluceth-20, Tea Tree Oil, preservatives, and Disodium EDTA, I'm facing issues with Titanium Dioxide WaterProof™ variants (300nm and 250nm). The 300nm version gives a natural look but lacks coverage, while the 250nm version provides good coverage but looks unnatural/white cast. How can I improve the coverage and dispersion of the 300nm variant? Should I mix the 250nm and 300nm versions? What ingredients should I add to prevent pigment separation/settling in the formula? Can the new Titanium Dioxide 400nm WaterProof™ (Super Coverage) be used in this body wash application?
