Thick, Waterproof Foundation Ingredients

Creating a thick, waterproof foundation that provides high coverage for concerns like tattoos, birthmarks, and scars requires a careful selection of key ingredients. While a precise formula with percentages cannot be provided without specific lab development, we can discuss the essential components and how they contribute to the desired properties.

Key Ingredient Types:

• Pigments: These provide color and coverage. For high coverage, a significant amount of pigments is needed.

  • Titanium Dioxide: Provides white coverage and contributes to UV protection. Products like Titanium Dioxide 400nm WaterProof™ (Super Coverage) are designed for maximum coverage.
  • Iron Oxides: These are the primary color pigments (Yellow, Red, Black) used to create various skin tones. Using types like Iron Oxides Yellow (FoundationPro™), Iron Oxides Red (FoundationPro™), and Iron Oxides Black (FoundationPro™) can help with dispersion and performance in foundation formulas.

• Waterproof Film Formers: These ingredients create a film on the skin that helps the foundation resist water and stay in place for extended periods.

  • Examples include Silicone Film (Soft Film, Low Viscosity, Isododecane Base) and Allianz OPT (Acrylates/C12-22 Alkyl Methacrylate Copolymer), which are designed to provide water and wear resistance.

• Silicones: Ingredients like Dimethicone (available in various viscosities such as Dimethicone (Medium/500, Low-Odor) or Dimethicone (Heavy/500k, Low-Odor)) are crucial for achieving a smooth texture, good spreadability, and a comfortable feel on the skin. They can also contribute to water resistance.

• Thickeners/Stabilizers: These are needed to create the desired thick consistency and ensure the formula remains stable over time, preventing separation of ingredients.

Adjusting Shades:

To achieve shades for fair-yellow and dark skin tones, you would adjust the ratios of the Iron Oxides (Yellow, Red, Black) and Titanium Dioxide.

• For fair-yellow tones, a higher proportion of Titanium Dioxide and Yellow Iron Oxide would be used, with minimal Red and Black Iron Oxides.
• For darker tones, the amount of Titanium Dioxide would be reduced, and the proportions of Yellow, Red, and Black Iron Oxides would be increased and adjusted to match the specific dark shade desired.

Developing a stable, high-coverage, waterproof foundation requires expertise in formulation to balance these ingredients correctly and ensure proper dispersion of pigments. The products mentioned above are examples of ingredients commonly used to achieve these properties.
