Hello, because I use
สารกันแดด at a high rate, the team thought there was a risk that the formulation could be stratified. Yes, I recommend that you add
Milk Lotion Maker 3-4% to help coordinate. Let the formula not cause separation. There are several levels of water resistance. Member's purpose is just to be able to sweat during the day or can go swimming The sunscreen can also stick on the skin. If you just want good waterproofing during the day, use
Polyethylene Wax 1-2% or
WaterGuard™ Lite 3-5% but if you want to be able to swim, use
WaterGuard™ Ultra 5-6% The recipe must use heat to mix it. due to melt
Milk Lotion Maker and water repellent such as
Polyethylene Wax dissolve it into the formula (
WaterGuard™ No heat needed)
