Cosmetics Formulation Development

Foundation SPF45/PA+++ has been prepared from the recommended website. with a percentage of use Titanium Dioxide & Zinc Oxide were 25 & 20% respectively, and total pigment was added at 7.3%. (According to the percentage shown below) and then sent to measure the SPF / PA value, then the SPF value is 100-130. I want to know what this increased value caused by? And if you want to get SPF 45/PA+++, what should you reduce? Please suggest me. (percentage of BB Micro Silk , Softgrow, and Pearl Red Mica (A) Formula texture and coverage are ok. I don't want to lose weight) Titanium Dioxide 15nm Liquid (eq=35% ) 25 Zinc Oxide 35nm Liquid 20 BB Micro Silk™ 7 White Iron Oxides EasyMix ( 5.6 Yellow Iron Oxides EasyMix™ 0.84 Black Iron Oxides EasyMix 0.44 Red Iron 0.44 Pearl Red Mica (A) 1-3% 1.5 Caprylyl Methicone 5 SoftGlow 3 SiliSolve Plus 3 LipidSoft™ CC 2 Fragrance 0.01 oil 3.2 water 21.97 Mild Preserve Eco 1 Thank you very much.

Hello, the study team informs the list of ingredients. That affects the SPF as follows: Titanium Dioxide 15nm Liquid Zinc Oxide 35nm Liquid BB Micro Silk™ SoftGlow 3 SiliSolve Plus 3 Summary, in case members want to reduce SPF, please reduce Titanium Dioxide 15nm Liquid and Zinc Oxide 35nm Liquid , SoftGlow can post it. that the usage rate SiliSolve Plus is too high, our team recommends trying to reduce to 1.5-2.0% should be enough to coordinate the formula and not provide stability. There has been a separation.

thank you very much
