Creating a Liquid Sunscreen with SPF Protect Ultra™ II or III

Yes, it is possible to create a liquid-textured sunscreen similar to Shiseido Anessa or Biore UV Perfect Face Milk using SPF Protect Ultra™ II or SPF Protect Ultra™ III.

To achieve a thinner, more liquid consistency, you can reduce the amount of cream maker used in the formulation. Products like Light Cream Maker™ are suitable for adjusting viscosity. Using a lower percentage of the cream maker will result in a less viscous, more fluid product.

SPF Protect Ultra™ II and SPF Protect Ultra™ III are chemical sunscreens. Therefore, the active sunscreen ingredients themselves are not expected to settle in the way that physical sunscreen powders like Titanium Dioxide or Zinc Oxide might. However, if you choose to add physical sunscreens to your formula for broader protection or other reasons, settling can occur, and you would need to shake the product well before each use, just like many commercial fluid sunscreens that contain physical filters.

Here is a conceptual guideline for a liquid formulation using SPF Protect Ultra™ II or III:

• Part A (Oil Phase):

  • SPF Protect Ultra™ II or III: 15-25% (Adjust percentage based on desired SPF level. Refer to product descriptions for guidance.)
  • Light Cream Maker™: 0.5 - 1% (Start with a low percentage for a liquid texture. You can adjust slightly to find your preferred viscosity.)
  • (Optional) Light Emollient (e.g., LipidSoft™): 1-5% (Can help with feel and solubility of the SPF active)

• Part B (Water Phase):

  • Water or Hydrosol: Balance (e.g., 73-83%)
  • Preservative (e.g., Mild Preserved Eco): ~1%

Mixing Method:

1. Combine ingredients in Part A and mix until homogeneous. Gentle warming (e.g., 70-80°C) might be needed to fully incorporate SPF Protect Ultra™ II or III, as mentioned in their descriptions.
2. Combine ingredients in Part B.
3. Slowly add Part B to Part A while continuously stirring or blending until the emulsion forms and is uniform. Avoid high-speed mixing which can damage the polymer in the cream maker.
4. Ensure all ingredients are fully dispersed and emulsified.

Remember that this is a basic guideline. You may need to experiment with the percentages of Light Cream Maker™ and other ingredients to achieve the exact texture and feel you desire. Always perform stability testing on your final formulation.
