Sunscreen Cream SPF 30

This formulation base utilizes Hallstar’s elegant sunscreen solvent and emollient HallBrite® BHB towards optimizing solvent polarity, to which triplet state-quenching polymeric silicone photostabilizer HallBrite® PSF has been added, providing substantial additional photostabilization to the composition. In vitro testing suggests SPF ~34 and PFA ~12 performance. Critical wavelength = 378 nm.

1In a secondary vessel combine phase A, start mixing, add phase B, heat to 85°C and then add phase C items in order.
2When phase ABC is homogeneous, add phase D and mix until well dispersed.
3Add Water of phase E to the main vessel and then add remaining phase E items in order, allowing full dissolution between additions.
4When phase E is homogeneous, start heating it to 80°C and add premixed Phase F to it.
5When phases ABCD and EF are homogeneous and at designated temperatures, slowly add oil phase ABCD to water phase EF with prop mixing.
6Start homogenizing and cooling batch. When batch reaches 55°C stop homogenizing, start sweep mixing and continue cooling.
7Add phase G ingredients in order, allowing full incorporation between additions. When batch is completely smooth, perform final quality assurance checks.
