Recommended Mixing Ratios for Foundation: Hyaluronic Acid Gel Base and WaterMix™
Question
Recommended mixing ratios for foundation between Hyaluronic Acid Gel Base and the WaterMix™ color group.
Answer
Creating a water-based foundation or tinted serum using Hyaluronic Acid Gel Base and WaterMix™ liquid colors is an effective way to achieve a hydrating, lightweight finish. Below are the recommended mixing ratios and techniques.
1. Base to Color Ratios by Coverage
The total amount of color dispersion added to the base determines the opacity:
- Sheer Tint: 93–96% Base + 4–7% Total WaterMix™ colors.
- Light Coverage: 88–92% Base + 8–12% Total WaterMix™ colors.
- Recommended Starting Point (Lab Trial): 90% Base + 10% Total Color.
2. Sample Formula for Asian Skin Tone (Light-Medium Beige)
For a 100g batch, use the following starting weights:
- Hyaluronic Acid Gel Base: 90.0 g
- WaterMix™ White (Titanium Dioxide): 8.0 g (Provides opacity and lightness)
- WaterMix™ Yellow (Iron Oxide Yellow): 1.5 g (Provides the primary undertone)
- WaterMix™ Red (Iron Oxide Red): 0.3 g (Adds warmth/peach tones)
- WaterMix™ Black (Iron Oxide Black): 0.2 g (Deepens the shade and mutes brightness)
3. Shade Adjustment Tips
- Too Pale/Chalky: Reduce the White and slightly increase Yellow and Red.
- Too Pink/Peach: Reduce the Red and increase the Yellow.
- Too Grey/Dull: Reduce the Black.
- Too Sheer: Increase the WaterMix™ White specifically, as it is the primary driver of coverage.
- Caution: Black is extremely potent; always add it drop-by-drop.
4. Mixing Instructions
- Premix the Colors: Mix your White, Yellow, Red, and Black dispersions together first to ensure the shade is correct before adding it to the gel base.
- Gradual Incorporation: Add the color blend to the Hyaluronic Acid Gel Base in 3–5 portions, mixing thoroughly between each addition to prevent streaking.
- Low Shear Mixing: Use moderate stirring. Avoid high-speed mixing that introduces excessive air bubbles.
- Stabilization: Let the mixture stand for 12–24 hours. The final color and viscosity often stabilize after this period.
Note: High pigment loads may slightly decrease the viscosity of the gel base. If the final product is too thin, a small amount of a water-based thickener may be required.

Question:
Recommended mixing ratios for foundation between Hyaluronic Acid Gel Base, the WaterMix™ color group, and Propylene Glycol (USP) for foundation stability. What are the recommended proportions?
Answer:
To create a stable, hydrating water-based foundation or tinted serum using Hyaluronic Acid Gel Base, WaterMix™ liquid colors, and Propylene Glycol (USP), the following ratios and guidelines are recommended for optimal performance and stability.
1. Recommended Mixing Ratios (Starting Point)
For a standard light-to-medium coverage foundation, use these proportions as a baseline for a 100g batch:
- Hyaluronic Acid Gel Base: 85.0 – 92.0%
- Propylene Glycol (USP): 3.0 – 5.0%
- WaterMix™ Colors (Total): 5.0 – 10.0%
Example Formula (100g):
- Hyaluronic Acid Gel Base: 86.0 g
- Propylene Glycol (USP): 4.0 g
- WaterMix™ White: 8.0 g (Main coverage provider)
- WaterMix™ Yellow / WaterMix™ Red / WaterMix™ Black: ~2.0 g (Adjusted for skin tone)
2. The Role of Propylene Glycol (USP) for Stability
Adding Propylene Glycol (USP) to this water-based system serves several critical functions:
- Freeze-Thaw Stability: It acts as an anti-freeze agent, preventing the formula from separating or changing texture during temperature fluctuations during shipping.
- Humectancy: It works synergistically with the Hyaluronic Acid and Glycerin already in the base to prevent the foundation from drying out too quickly on the skin or in the bottle.
- Solvent Action: It helps the water-dispersed pigments integrate more smoothly into the gel network.
3. Enhancing Long-Term Stability (Anti-Settling)
While Propylene Glycol improves the "wet phase" stability, it is not a primary suspending agent. Because WaterMix™ colors contain dense minerals (Titanium Dioxide and Iron Oxides), they may eventually settle in a thin gel.
- Pro Tip: If you notice pigment settling over time, add a small amount of a suspending polymer such as Xanthan Gum (0.2%) or Hydroxyethylcellulose (HEC) (0.3–0.5%) to increase the "yield value" of the gel, keeping the pigments suspended indefinitely.
4. Recommended Mixing Procedure
- Incorporate Propylene Glycol: Mix the Propylene Glycol (USP) directly into the Hyaluronic Acid Gel Base first. Stir until the mixture is uniform and clear.
- Premix Colors: In a separate small container, blend your WaterMix™ White, WaterMix™ Yellow, WaterMix™ Red, and WaterMix™ Black to achieve the desired shade.
- Gradual Addition: Slowly add the color blend into the gel base while stirring at moderate speed. Adding color in small increments ensures even distribution without streaking.
- Final Check: Allow the formula to rest for 12–24 hours to check the final viscosity and color stability before packaging.
