This antidandruff shampoo formulation uses particulate zinc pyrithione as its active ingredient, and HallStar® SAB-2N Flake to maintain the active ingredient in dispersed form. HallStar® SAB-2N Flake also contributes opacity as well as desirable rheological properties to the finished product. By using RTD Coco Sulfate rather than sodium lauryl sulfate, formulations will typically have denser and creamier foam and may be translucent rather than clear. Foam quantity may be adjusted by modifying the level of RTD Coco-Sulfate.
