Achieving High Waterproofing in Water-in-Oil Sunscreen Formula
Question
I have a Water-in-Oil sunscreen formula and want to make it highly waterproof for both face and body. How can I modify the formula to achieve this?
The recommended modified formula is:
- SPF Protect Ultra II 15%
- Water-in-Oil EZ™ 4%
- Cyclopentasiloxane (Low-Odor Cyclomethicone) 10%
- Polyethylene Wax 3%
- Water (remaining 68%)
Answer
Highly Waterproof Sunscreen Formula for Face and Body
Yes, the formula you proposed can be made, and the staff has provided a valuable modification to significantly enhance its waterproof properties.
The original formula included Mineral Oil, which the staff recommended removing. To achieve a much higher level of water resistance, they suggested adding 3% of Polyethylene Wax.
Polyethylene Wax is effective in creating a protective film on the skin, which is key to making a Water-in-Oil formula highly waterproof.
Based on the staff's recommendation, the modified formula for a highly waterproof sunscreen suitable for both face and body is:
- SPF Protect Ultra II 15%
- Water-in-Oil EZ™ 4%
- Cyclopentasiloxane (Low-Odor Cyclomethicone) 10%
- Polyethylene Wax 3%
- Water (remaining 68%)
This adjusted formula is designed to provide the desired high level of water resistance for application on both the face and body.
