Broad Spectrum SPF 47, PFA (PPD) ~24 Sunscreen Cream UVA1/UV = 0.82

Preparation:

In a secondary vessel, combine 1 through 6 and start mixing. Add 7 and 8 and start heating to 80°C. When above 60°C add 9, 10 and then 11. To the main vessel add 12, start mixing, and add 13. When dissolved add 14 and, when fully incorporated, start heating to 80°C and add premix of 15 and 16. With both phases homogeneous and at 80°C, add the oil phase (1-11) to the water phase (12-16) with prop stirring and then homogenize for five minutes. Switch from homogenization to sweep mixing and cool to ambient temperature. Add water as needed to correct for evaporative loss and, when again uniform, perform final quality assurance checks.
