Sunscreen Cream SPF 50+

Formula Number: JZ7-66

This sunscreen cream formulation was designed to provide superb broad spectrum (SPF/PFA <<3) label SPF 50+ performance. SolaStay® S1 and SolaStay® P1 provide very rapid and efficient excited state quenching of Avobenzone, protecting it from photodegradation and so improve sunscreen performance. They also mitigate the photocatalytic and reactive oxygen species generating activities of Titianium Dioxide. HallBrite® BHB and HallTress® DIBA contribute to UV filter solubility and enhanced product feel. Olivem® liquid crystal making emulsifiers provide a stable emulsion while imparting sensorial and physiological benefits. This formulation was subjected to in vitro analysis and delivered SPF ~ 65, PFA(PPD) ~ 58, 5 Stars UVA/UVB (1.01 – 1.01) performance with critical wavelength 381 nm.

PREPARATIVE PROCEDURE

1In a secondary vessel combine phase A, start mixing and slowly add phase B ingredients, in order, with continued mixing.
2Heat this oil phase AB to 75°C and then add phase C ingredients, in order, with mixing.
3Add phase D to phase ABC and mix well until Avobenzone is dissolved.
4Add water of phase E to the main vessel, dissolve the Disodium EDTA and, with continue mixing, add the Xanthan Gum.
5When the Xanthan Gum is fully incorporated, start heating this water phase E to 75°C and add premixed phase F with mixing.
6When both phases are homogeneous and at their designated temperatures, slowly add oil phase ABCD to water phase EF with prop mixing.
7Homogenize combined phases for 3 minutes and then resume prop mixing and start cooling batch.
8 When batch is at room temperature, replace any water lost to evaporation and mix until batch is smooth.
