Waterproof Shimmer Sunscreen Formulation using Water-in-Oil EZ

Hello,

Regarding the request for a lightweight, easy-to-spread, waterproof, sweatproof sunscreen formula with gold shimmer, and the mixing instructions, based on the staff's recommendation, here are the details:

This formula uses a Water-in-Oil emulsifier (Water-in-Oil EZ) and Cyclomethicone, which helps create a lightweight, non-greasy feel despite being water-resistant. The Gold Glitter Mica will provide the desired shimmer.

Here is the formula:

• SPF Protect Ultra II: 15%
• Water-in-Oil EZ: 3%
• Cyclomethicone: 7%
• Gold Glitter Mica (Size A): 1-2% (You can adjust this amount based on how much shimmer you want)
• Mild Preserved Eco: 1%
• Water (Distilled Water): Remaining % (Add enough to make the total 100%)

Expected Texture:
The resulting cream should be lightweight, easy to spread, non-greasy, and water-resistant, with a visible golden shimmer.

Mixing Instructions (A Blender is Required):

1. Prepare the Oil Phase: In one container, combine SPF Protect Ultra II, Water-in-Oil EZ, and Cyclomethicone. Mix these ingredients together.
2. Prepare the Water Phase: In a separate container, combine Water (Distilled Water) and Mild Preserved Eco. Mix these ingredients together.
3. Add Mica: Add the Gold Glitter Mica to the Oil Phase mixture and stir to disperse it.
4. Start Blending: Using a blender (like a hand blender or homogenizer), begin blending the Oil Phase mixture.
5. Combine Phases: Slowly add the Water Phase mixture to the Oil Phase in a thin, steady stream while continuously and vigorously blending with the blender.
6. Emulsify: Continue blending until all the ingredients are well combined and a smooth, stable cream has formed. This may take a few minutes of continuous blending.
7. Final Check: Ensure the cream is fully emulsified and smooth. If it looks separated or uneven, continue blending.

Important Note: As the staff mentioned, this type of formula requires a blender for proper emulsification. It is also highly recommended to review the detailed instructions for using Water-in-Oil EZ on its product page on the MySkinRecipes website before you start mixing, as it provides specific guidance for this emulsifier.

Hope this information helps you get started!
