Enhancing Water-Based Physical Sunscreen
Question
How to enhance a water-based physical sunscreen formulation using water-dispersible Titanium Dioxide to achieve broad-spectrum protection, and what other water-dispersible physical filters can be added?
Answer
Enhancing Water-Based Physical Sunscreen
To enhance the sun protection efficiency of your water-based physical sunscreen using Titanium Dioxide Transparent (15nm, Water-Dispersion) and achieve broad-spectrum coverage (protecting against both UVA and UVB rays), you should add Zinc Oxide.
Zinc Oxide is another physical sunscreen ingredient that provides excellent protection, especially against UVA rays, which Titanium Dioxide alone may not fully cover. Combining both physical filters creates a more robust and complete sunblock.
Since you are aiming for a water-based formula, it is recommended to use a water-dispersible form of Zinc Oxide, such as Zinc Oxide 40nm Dispersion (Water Base). This type is designed to be easily incorporated into water-based systems, maintaining the desired texture and feel of your sunscreen.
By combining Titanium Dioxide Transparent (15nm, Water-Dispersion) and Zinc Oxide 40nm Dispersion (Water Base), you can create a highly effective, broad-spectrum physical sunscreen that remains water-based.
