Sunscreen Formulations: Water Break and Powder Finish
Question
I am asking about sunscreen formulations. I want to create two types of sunscreen:
- Water-breaking formula: A formula that breaks into water droplets upon application.
- "Silk/Powder Foam" formula: A formula that does not feel like a cream but dries down to a powder-like finish, is smooth, easy to spread, and non-sticky.
Could you provide guidance or formulas for these two types of sunscreen?
Answer
Okay, I understand you're asking about the formula provided by the staff.
The staff proposed a water-breaking physical sunscreen formula aiming for SPF 50 (based on your request). The formula is as follows:
- Titanium Dioxide 200nm EasyDisperse™: 5%
- Zinc Oxide 200nm: 5%
- Cyclomethicone: 10%
- SiliSolve Plus: 1%
- Mild Preserved Eco (or any preservative): 1%
- Water: Remaining percentage (which is 78%)
Based on the staff's previous explanation, your original formula did not achieve the water-breaking effect because the water content was too low. This new formula significantly increases the water content to 78%, which is necessary for the water-breaking effect to occur when applied to the skin.
For the "silk/powder foam" type sunscreen, the staff directed you to the Silicone Blender product page for an example formula. I cannot directly provide the formula from that page.
This proposed water-breaking formula addresses the issue of insufficient water in your previous attempt and uses ingredients suitable for a physical sunscreen base.
