Broad Spectrum SPF 30 Sunscreen Cream

This sunscreen cream was designed to provide broad spectrum (SPF/PFA ≤3) performance. SolaStay® S1 is incorporated to rapidly and efficiently quench the excited states of Avobenzone, protecting it from photodegradation and so improving sunscreen performance. HallBrite® BHB contributes to UV filter solubility and enhanced product feel. This formulation was subjected to in vitro analysis and delivered SPF ~32, PFA (PPD) ~13 performance with critical wavelength 377 nm.

PREPARATIVE PROCEDURE

1To a secondary vessel add phase A, start mixing, add phase B ingredients, heat phase AB to 85°C and then add, in order, phase C ingredients.
2Add the water from phase D to the main vessel, dissolve Disodium EDTA and, with continued mixing, add Xanthan Gum.
3When Xanthan Gum is fully incorporated, start heating phase D to 80°C and add premix of phase E to phase D.
4When both phases are homogeneous and at their designated temperatures, slowly add oil phase ABC to water phase DE with prop mixing.
5After prop mixing for 2 minutes, start cooling batch with continued mixing.
6When batch is below 50°C add phase F and continue mixing and cooling until batch is at room temperature.
7Replace any water lost to evaporation, mix batch until smooth and perform quality assurance checks.
