Sunscreen Lotion SPF 30

This formulation was designed to US use. HallBrite® ISO is incorporated to mitigate the photocatalytic and reactive oxygen species generating activities of Titanium Dioxide , protecting it from photodegradation, and so improve sunscreen performance. HallBrite® BHB aids wetting and dispersion of the Titanium Dioxide and contributes to UV filter solubility and enhanced product feel. This formulation was subjected to in vitro analysis and delivered SPF ~35, PFA (PPD) ~5 performance with critical wavelength 373 nm.

2Heat phase AB to 80°C and then add phase C ingredients in order with mixing.
3To the main vessel add Water of phase D with mixing, add Disodium EDTA, then add Xanthan Gum, and heat this phase to 75°C.
4When both phases are homogeneous at their designated temperatures, slowly add phase ABC to phase D withmixing.
5Homogenize for 3 minutes and resume prop mixing.
6Start cooling and when below 50°C, slowly add previously prepared phase E dispersion, and then add phase F with mixing.
