    Hello everyone,
    I’ve been trial for this formula, but I’m so confussed how to fix the spf but didn’t change the texture of my two way cake, because I used my current compact powder’s formula and I modified with adding UV filter (EHMC, ZnO and TiO2 in my based) and it’s look the payoff is so bad and not coverage. Below is attached my current formulation that I’ve trial for powder cake:
    1. Talc 2 KAS : 55%
    2. Mica AS : 10 %
    3. Tospearl 3000A : 2.5 %
    4. PMMA : 5 %
    5. Silica : 2 %
    6. ASO-I2 : 1 %
    7. Softouch CC6097 : 3%
    8. Zinc myristate : 1.5%
    9. EA-209 : 0.4%
    10. TiO2 : 6%
    11. ZnO : 4 %
    12. Salicylic acid : 1%
    13. Dimethicone 5cs : 5 %
    14. Dimethicone 350cs : 1.5 %
    15. Uvinul MC80 : 4%
    16. Hydrogenated polydecene : 1%
    17. Phytosqualane : 0.5%
    18. Chamomile extract : 0.5%

    If you guys have any advise about this problem, kindly please share to me. Thanks!
