Question
What percentage of AquaForce™ BEMT should be used to achieve equivalent UV protection as 10% Tinosorb S (BEMT) powder in a formulation?
Answer
Comparing the required percentage of AquaForce™ BEMT to pure Tinosorb S (BEMT) powder at 10% is not a direct one-to-one comparison. Here's why:
- Dispersion Technology: AquaForce™ BEMT (Product ID 127242) is a water dispersion of BEMT that utilizes advanced technology to ensure the BEMT powder is fully dispersed. This superior dispersion significantly enhances the efficacy of the BEMT.
- Enhanced Efficiency: Because the BEMT in AquaForce™ BEMT is so well dispersed, a lower concentration of BEMT (on a dry weight basis) from AquaForce™ BEMT can provide equivalent or even better UV protection compared to a higher concentration of pure BEMT powder (Product ID 772) which needs to be dissolved or dispersed in your formulation.
Therefore, you would likely need a lower percentage of AquaForce™ BEMT (which contains 20% BEMT) in your formula to achieve similar or better protection than using 10% of the pure BEMT powder. The exact percentage needed would depend on your specific formulation and desired SPF/UVAPF values, and would ideally be determined through testing.
