คำถาม
I have developed a CC Cushion formula intended to be a Water-in-Silicone or Water-in-Oil type, aiming for a lightweight, waterproof product with coverage and sun protection.
The formula includes:
- Silicones (Cyclomethicone)
- Emulsifier/Stabilizers (SiliSolve Plus, Oil-Fix, Bentonite)
- Sunscreens (Titanium Dioxide, Zinc Oxide, Ethylhexyl Methoxycinnamate)
- Film Former (Silicone Film)
- Powders (Polymethylsilsesquioxane, Silk Talc Powder, Nylon-12)
- Active Extracts (Centella Asiatica, Licorice, Chamomile, Calendula, Active Resveratrol)
- Acne bee extract
My questions are:
- Is this formula suitable for achieving the desired properties (waterproof, lightweight, coverage, sun protection)?
- What is the approximate SPF value of this formula with the specified sunscreen percentages?
- Can I replace the Titanium Dioxide, Zinc Oxide, and Ethylhexyl Methoxycinnamate with
SPF Protect Ultra II? - If so, what percentage of
SPF Protect Ultra IIshould I use to achieve SPF50 PA++ and SPF90 PA++? - What is the recommended mixing procedure and equipment for this type of formula (Water-in-Silicone/Oil emulsion)? Is a standard stirrer suitable, or is a high-shear mixer necessary for stability?

CC Cushion Formula Review and SPF Information
Thank you for providing your CC cushion formula. Based on the ingredients you've included, this formula is designed as a water-in-silicone or water-in-oil emulsion, which is suitable for creating a lightweight, waterproof CC cushion with coverage and sun protection.
The key components in your formula are well-chosen for this type of product:
- Silicones (Cyclomethicone): Provide a lightweight feel and aid in spreading.
- Emulsifier/Stabilizers (SiliSolve Plus, Oil-Fix, Bentonite): Help to bind the water, oil, and silicone phases and improve formula stability, which is crucial for water-in-oil/silicone emulsions.
- Sunscreens (Titanium Dioxide, Zinc Oxide, Ethylhexyl Methoxycinnamate): Offer broad-spectrum UV protection.
- Film Former (Silicone Film): Contributes to the long-wear and waterproof properties.
- Powders (Polymethylsilsesquioxane, Silk Talc Powder, Nylon-12): Enhance texture, provide soft-focus, absorb oil, and improve coverage and adherence.
- Active Extracts (Centella Asiatica, Licorice, Chamomile, Calendula, Active Resveratrol): Add beneficial skincare properties like anti-inflammation, soothing, and anti-aging.
Regarding your questions:
- Suitability of the formula: The formula appears suitable in terms of ingredient selection and percentages for a CC cushion aiming for waterproof, lightweight feel, and coverage. As previously discussed by the staff, achieving good stability in a water-in-oil/silicone formula requires sufficient mixing power. While your modified mixer might work, a proper high-shear mixer is generally recommended for optimal emulsification and long-term stability to prevent separation.
- SPF Value: The exact SPF value of your formula cannot be precisely calculated without laboratory testing, as it depends on the specific interaction and dispersion of the sunscreens within the final base. However, the combination of 5% Titanium Dioxide, 5% Zinc Oxide, and 5% Ethylhexyl Methoxycinnamate provides broad-spectrum protection against both UVA and UVB rays.
- Substitution with SPF Protect Ultra II: Yes, you can use SPF Protect Ultra II to replace the Titanium Dioxide, Zinc Oxide, and Ethylhexyl Methoxycinnamate in your formula. SPF Protect Ultra II is a pre-optimized blend of chemical sunscreens designed to provide specific SPF/PA levels.
- To achieve SPF50, PA++, you would typically use 15% SPF Protect Ultra II.
- To achieve SPF90, PA++, you would typically use 30% SPF Protect Ultra II.
Keep in mind that SPF Protect Ultra II is a blend of organic/chemical filters, whereas Titanium Dioxide and Zinc Oxide are physical filters. Substituting might slightly alter the feel and appearance of the final product compared to using physical filters. You would need to adjust the percentage of Water accordingly when substituting.
