HallBrite® ISO is incorporated to mitigate the photocatalytic and reactive oxygen species generating activities of oxides, protecting it from photodegradation, and so improve sunscreen performance. HallBrite® BHB aids wetting and dispersion of oxides and enhanced product feel. This formulation was subjected to in vitro analysis and delivered SPF ~38, PFA (PPD) ~12 performance with critical wavelength 379 nm.

1 | In seconadary vessel, combine phase A and mix well. Disperse phase B with mixing. Heat AB to 80C. |
2 | Add phase C into phase AB with mixing until homogenous |
3 | In the main vessel, add water od phase D, dissolve EDTA. Add xanthan gum and mix until fully incorporated. |
4 | Heat main vessel to 80C, and premixed of phase E. |
5 | When oil phase (ABC), and water phase (DE) homogenous and at their designated temperatures, add phases ABC into phases DE with prop mixing. |
6 | Homogenize for 3 minutes. Resume prop mixing, and start cooling it down to the room temperature. |
7 | When batch is below 50C, add Cyclopentasiloxane with mixing. Add Simulgel 600 at 35C if batch is too thin. |
8 | Add water lost |
