Silicone Mousse Sunscreen with Foundation Formula

Based on the previous discussion, here is a suggested starting formula for a silicone mousse sunscreen with foundation properties. This formula uses a silicone gel base with dispersed powders for UV protection and color.

Suggested Formula

• Silicone Gel (Ultra Clear, Super Silky): 70-75%
  • Provides the mousse texture and a soft, smooth feel.
• Titanium Dioxide 200nm EasyDisperse™: 10%
  • Offers UV protection and contributes to coverage and texture. This treated version disperses easily in silicone.
• Zinc Oxide 200nm EasyDisperse™: 5%
  • Provides broad-spectrum UV protection. This treated version disperses easily in silicone.
• Mica Powder (20 Micron, Methicone Coated): 5-10%
  • Adds coverage, softness, and a natural feel. This coated version blends well in powder/silicone formulas.
• Iron Oxide Blend (Red, Yellow, Black - Methicone Coated): 1-5%
  • Used to adjust the color to match the desired skin tone. These coated versions blend well.

Instructions

1. Weigh all the powder ingredients (Titanium Dioxide, Zinc Oxide, Mica, and Iron Oxides) and the Silicone Gel separately.
2. Gradually add the powder mixture to the Silicone Gel.
3. Mix or stir continuously until all powders are evenly dispersed and a homogeneous, smooth mousse consistency is achieved.
4. Adjust the percentage of Iron Oxides to get the desired foundation color match.
5. You may slightly adjust the percentages of Titanium Dioxide, Zinc Oxide, and Mica to fine-tune the texture, coverage, and SPF level.

This formula provides a good starting point for creating a silicone-based sunscreen mousse with foundation benefits. The treated powders are selected for their ease of dispersion in silicone systems, which is key for this texture.
