Broad Spectrum Oil-in Water SPF 50 Sunscreen Lotion

This broad spectrum sunscreen lotion is Oxybenzone- and Octocrylene-free and uses SolaStay® S1 to mitigate the photocatalytic and reactive oxygen species generating activity of the oxide and to photostabilize Avobenzone and Octioxate via extremely rapid excited state quenching. The formula was subjected to in vitro analysis and delivered SPF ~60, PFA (PPD) ~27 performance with critical wavelength 382 nm.

1To a secondary vessel add phase A, start mixing and slowly add phase B components individually to phase A with continued mixing.
2Heat phase AB to 85°C and then add phase C ingredients with mixing. Add phase D to phase ABC and mix until phase D is fully dissolved.
3To the main vessel add water and Glycerin of phase E, start mixing, add the Disodium EDTA, then add Xanthan Gum and heat this phase to 80°C.
4When both phases ABCD and EF are homogeneous and at designated temperatures, slowly add phase ABCD to phase EF with mixing.
5Start homogenizing intensively for 3 minutess and start cooling. When the batch is < 50°C, add phase F ingredients one by one with mixing.
