water 53.9 Sodium PCA 1 LipidSoft CC 9 titanium dioxide easy dis 1 Zinc Oxide nano 5 SPF Protect Ultra II 12 Water in Oil EZ 2.5 Isododecane 6 Cyclomethicone 3 Aloe Vera Extract 1 Phenoxyethanol SA 0.5 Vitamin E (Tocopheryl Acetate) 0.1 Oil Fix 1 Polymethylsilsesquioxane 4 According to this formula, set aside Wow, and the layers are separated. Can I use silicone plus to help coordinate? Another thing that I can't see Oil Fix on the web page. Well, it's not for sale anymore, right? We can only use silcone plus. Can you help me to coordinate it instead? or if there is another Please recommend

Hello Oil Fix is also available. as usual You can click on the name. This formula is recommended to try to fix the following first. should not yet be required. SiliSolve Plus because the price is very high 1. Adjust Water-in-Oil EZ increase to 3.5% 2. Add Oil-Fix to 2% 3. Add Magnesium Sulfate 2% added in the last step. Blend until dissolved. (May take about 15-30 minutes.) If not really. may consider filling SiliSolve Plus 1% because the proportion of oil, silicone in the formula is quite a lot, leaving 53.9% of water, making it a little difficult to combine. But try the steps above first. to control the cost of the formula

Regardless of cost, using SiliSolve Plus fix the problem? because I used to add Water in Oil and Oil Fix and it affects the viscous texture. If everything is preserved, just add SiliSolve Plus and make the texture the same. ซิลิโคน so it's ok, haven't tried it yet Magnesium Sulfate will this affect the texture of the original formula?

Hello SiliSolve Plus will help better synchronization and may be used. Silicone Blender will also be more complete. This does not mean that the formula is stable, there is absolutely no stratification, always, always testing. From the member's formula, try changing Water-in-Oil EZ to SiliSolve Plus 2% combined with Silicone Blender 4%, the rest remain the same. The procedure remains the same: blend the oil/silicone well, then slowly add the water part into the oil/silicone part. while spinning at high speed Magnesium Sulfate will improve stability. Even more. The formula Water-in-Oil will give meat. Good touch for dry skin. And will provide waterproof performance and provide a higher SPF, but the process may be more difficult than conventional oil-in-water formulas.

is to use SiliSolve Plus 2% + Silicone Blender 4% instead of Water in Oil 2.5%, right? and then go down in the lower part of the water Will the formula be waterproof and smooth? then it is called as a formula ซิลิโคน base? Actually, it doesn't exist in the formula. ซิลิโคน Why use it? Silicone Blender reach 4% and still need to add Magnesium Sulfate or try do it first

Hello,
is to use SiliSolve Plus 2% + Silicone Blender 4% instead of Water in Oil 2.5%, right? and then go down in the lower part of the water Will the formula be waterproof and smooth?
Yes, the texture will improve from Silicone Blender that looks like a gel. ซิลิโคน but the waterproofing may not be more because Water-in-Oil EZ can also make the formula waterproof.
then it's called a formula. ซิลิโคน base
can't be called that. Because water is still the main component of the formula (>50%)
, it's actually not in the formula. ซิลิโคน so much, why use it? Silicone Blender to 4%
improves stability in formulas. Water in Oil /silicone as the member's recipe.
then still have to enter Magnesium Sulfate or try Let's do it first
since it's a low-cost ingredient. and has a positive effect on the stability of the formula. Therefore, it is recommended that if it can be worn, it should be worn for better stability. especially when producing for sale
