Quench-and-Protect 30 Lotion – Broad Spectrum O-W SPF 30 Sunscreen

This oil-in-water sunscreen lotion provides broad spectrum sun protection. SolaStay® S1 (Ethylhexyl Methoxycrylene) mitigates the photocatalytic and reactive oxygen species-generating activities of titanium dioxide and extremely rapidly and efficiently quench the excited states of Avobenzone, protecting it from photodegradation and so improve sunscreen performance.
This formula was subjected to in vitro analysis and delivered SPF ~ 35, PFA (PPD) ~ 13 performance with critical wavelength 379 nm.

PREPARATIVE PROCEDURE

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 phase E, start mixing, then add items of phase F in order 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 for 3 minutes and start cooling. When the batch is below 50°C, add phase G items one by one with mixing.
6When the batch is uniform add deionized water to correct for evaporative losses. Continue mixing until smooth.
