General Mixing Instructions and Percentage Guidance

Cushion foundations are typically Water-in-Silicone (W/Si) or Water-in-Oil (W/O) emulsions. This structure provides a lightweight feel, good spreadability, and often water resistance.

Basic Mixing Steps (General):

1. Prepare the Oil/Silicone Phase: Combine all oil-soluble/silicone-soluble ingredients, including silicones, emollients, oil-phase thickeners, waxes, and silicone emulsifiers. Heat gently if necessary to melt waxes, then cool slightly. Add Propylene Carbonate if using an organoclay thickener.
2. Prepare the Water Phase: Combine water, humectants, water-soluble actives, water-phase thickeners, and chelating agent. Heat gently if needed to dissolve solids. Add Sodium Chloride. Ensure everything is fully dissolved.
3. Prepare the Pigment Phase: Disperse the pigments (Titanium Dioxide, Iron Oxides) thoroughly in a portion of the oil/silicone phase or a suitable dispersing agent. Proper pigment dispersion is crucial for color uniformity and stability and often requires high shear mixing.
4. Emulsification: Slowly add the water phase to the oil/silicone phase while mixing with high shear. Continue mixing until a stable emulsion forms.
5. Incorporate Pigment Paste: Add the pre-dispersed pigment phase to the emulsion and mix thoroughly until the color is uniform.
6. Add Fragrance (Optional): Add fragrance at the end, mixing gently.
7. Adjust Viscosity/Stability: Check the viscosity and stability. Adjust if necessary by adding more thickener or emulsifier, or by adjusting the phase ratio.
8. Filling: Fill the finished product into the cushion compacts.

Regarding Percentages:

Providing exact percentages is difficult without specific product grades and extensive testing. However, here are typical ranges for categories of ingredients in emulsion systems like this. These are starting points and will require significant experimentation:

• Water: 40-70%
• Silicones (Cyclopentasiloxane, Dimethicone, etc.): 10-30%
• Emollients/Oils (Diethylhexyl Carbonate, Hydrogenated Polydecene, Shea Butter): 5-20%
• Silicone Emulsifiers (Lauryl PEG-9, Cetyl PEG/PPG-10/1, PEG-10 Dimethicone): 2-10% (depending on the specific emulsifier and phase ratio)
• Thickeners (Water phase - HEC, Cellulose Gum; Oil phase - Hectorite Gel, Mineral Oil Gel): 0.1-2% (highly dependent on the thickener type)
• UV Filters (Titanium Dioxide, Zinc Oxide): 5-20% (depending on desired SPF and coverage)
• Color Pigments (Iron Oxides): 1-10% (highly dependent on desired shade and coverage)
• Humectants (Glycerin, Glycols, Hyaluronic Acid): 1-10%
• Actives (Niacinamide, Allantoin, Extracts, Adenosine): 0.1-5% (depending on the active and its recommended usage)
• Salts (Sodium Chloride): 0.1-1% (for W/Si thickening)
• Chelating Agents (EDTA): 0.05-0.2%
• Preservatives: 0.5-1.5% (ensure compatibility with the formula)
• Fragrance: 0.1-0.5%

Important Considerations:

• Emulsifier Selection: The choice and combination of silicone emulsifiers are critical for the stability of a W/Si or W/O emulsion.
• Pigment Dispersion: Achieving a smooth, uniform color requires proper dispersion of pigments. Using a high-speed mixer or a bead mill is often necessary. Pre-dispersed pigments can simplify this step if available.
• Stability Testing: Any new formulation must undergo stability testing (e.g., heat/cold cycles, centrifuge) to ensure it does not separate over time.
• Preservation: A broad-spectrum preservative system is essential for any water-containing cosmetic product.
• Texture and Feel: The percentages of silicones, emollients, and thickeners will significantly impact the final texture and feel of the cushion foundation.
