Formulation Compatibility and Mixing Instructions

Yes, the ingredients you listed can generally be combined to create a tinted cream or BB cream with SPF. Here's a breakdown of the compatibility and a suggested mixing method:

Compatibility:

• SPF Protect Ultra™ III (assuming this is the "SPF Protect Plus") is an oil-soluble sunscreen blend that is compatible with oil phases in emulsions.
• Light Cream Maker™ is an oil-in-water emulsifier that works without heat and can incorporate an oil phase containing the sunscreen.
• BB Micro Silk™, Mica Powder, Pearl Silver Mica, and Beige Iron Oxides EasyMix™ are powders. They can be dispersed in either the oil or water phase, or a small amount of a compatible liquid (like an oil or silicone) before being added to the emulsion to ensure even distribution and prevent clumping.
• Water is the base for the water phase of the emulsion.
• A Preservative is essential for preventing microbial growth in the water-containing formula. The choice of preservative depends on the desired pH range and other formula characteristics.

Mixing Method:

Here is a general method for combining these ingredients. You will need to determine the exact percentages for the water, mica powders, iron oxides, and preservative to reach 100% of the formula.

1. Prepare the Water Phase: Combine water and any water-soluble ingredients (like your chosen preservative, if it's water-soluble) in a beaker. Stir until fully dissolved.
2. Prepare the Oil Phase: In a separate beaker, combine SPF Protect Ultra™ III and Light Cream Maker™. If using LipidSoft™ SPF to help dissolve the sunscreen, add it here as well. Stir to mix.
3. Create the Emulsion: Slowly add the oil phase to the water phase while continuously stirring. Continue mixing until a homogeneous cream is formed. Light Cream Maker™ typically forms a cream within 1-5 minutes with continuous stirring.
4. Disperse Powders: In a small container, disperse the BB Micro Silk™, Mica Powder, Pearl Silver Mica, and Beige Iron Oxides EasyMix™ in a small amount of oil or silicone that is compatible with your formula. Mix thoroughly to create a smooth paste free of clumps.
5. Add Powder Dispersion: Add the dispersed powder mixture to the cream base from step 3. Mix thoroughly until the powders are evenly distributed and the color is uniform.
6. Add Remaining Ingredients (if any): If your preservative was not added in step 1, add it now and mix well.
7. Final Adjustments: Check the pH of the final product and adjust if necessary, depending on the requirements of your preservative.

Remember to perform stability testing on your final formulation to ensure the ingredients remain well combined over time.

Please note that the exact percentages for Water, Silk Mica Powder, Pearl White Mica, Beige Iron Oxides EasyMix, and the preservative are needed to complete your formula.
