Powder Formulation: Completing the Formula and Adding Color

Based on your proposed formula of Silk Mica Powder (Matte) 10% and Polymethylsilsesquioxane 5%, you will need to add other ingredients to reach 100%.

For the remaining percentage (85%), you can add a base powder. As suggested by the staff, Silk Talc Powder can be used. If you prefer to avoid Talc, you could use other base powders like Silk Mica Powder (Matte) or Silk Sericite Powder (Matte).

To add a beige color, you can use Beige Iron Oxides EasyMix. The amount needed will depend on the desired skin tone match.
