Please inquire about sunscreen formula Water-in-Oil with waterproof foundation by using Polyethylene Wax 5 g 1. Water-in-Oil EX 3% 2. SPF Protect Ultra II 5% 3. Polyethylene Wax 2% 4. LipidSoft TM Disperse 5% 5. Silk Mica Powder 20% 6.Beige Iron Oxides Easy Mix 1% 7.Titanium Dioxide 200 nm Easy DisperseTM 3% 8. Mild Preserved Eco 1% 9. Rest of water Step 1 .To mix 5+6+7 2. Heat the water 9 to a temperature of 65 degrees with the dissolution of the oil to the same 65 degrees 1+2+3+4+8 3. Pour the water mixture into the mixture. The oil is stirred to combine. 4. Then add the flour that has been stirred and slowly poured, stirring continuously until it starts to harden. The result is creamy sticking together. Difficult to spread, the cream will stick on the skin along the pores. What happened? Please ask. Thank you very much. Note. I don't have a blender. I use it with stirring and when making the cream it dries very quickly. thank you very much

According to our opinion Water-in-Oil can't be manned by hand. blender and that the cream is very thick because Silk Mica Powder that should have been put on too much. I myself have encountered the same kind of problem. Anyway, wait for someone more knowledgeable to answer.

Hello, please adjust the formula by - Reduce the powder ingredients, which are items 5,6,7, the total should not exceed 10% of the formula. Therefore, please reduce the 5th item to 6% or lower. - Increase the proportion of emollient let even more by having emollient in the formula, not less than 10%, may be added LipidSoft Disperse to 10% or maybe use LipidSoft Disperse 5% combined LipidSoft other 5% or may be used. Silicone eg Dimethicone (Very Light/5, Low-Odor) for a smooth texture. And it's easy to spread. - Formula Water-in-Oil should have to use a blender So that the formula is compatible and coordinated perfectly.
