Pressed Powder Foundation: Mixing Steps, Adding Actives & Sunscreen

Based on the formula and the information provided, here are the steps to make the pressed powder foundation:

Mixing Steps:

1. Combine ingredients 1-5: Oil Thick™, LipidSoft™ Lite, Microcrystalline Wax, Isododecane, and Isohexadecane.
2. Heat this mixture to a high temperature, around 85-90°C, and stir until all ingredients, especially Oil Thick™, are completely dissolved and the mixture is clear.
3. In a separate container, combine the powder ingredients: MatteSilica, Beige Iron Oxides EasyMix™, and Silk Talc Powder.
4. Gradually add the heated liquid mixture from step 2 to the powder mixture from step 3 while continuously mixing thoroughly until a uniform consistency is achieved.
5. Once well mixed, the mixture is ready to be pressed into a suitable container to form the pressed powder foundation.

Regarding the Wax:
Microcrystalline Wax melts at a temperature of about 60-70°C. Since you need to heat the mixture to 85-90°C to dissolve the Oil Thick™, the wax will easily melt and incorporate into the mixture at this higher temperature, despite its initial appearance.

Adding Nourishing Ingredients and Sunscreen:
You can add nourishing ingredients and sunscreen agents (both physical and chemical types) to this formula. However, it is recommended to keep the total amount of these added ingredients to a small percentage, ideally around 5%, to avoid significantly altering the texture and binding properties of the pressed powder foundation.
