I ordered 2 types of Water in Oil emulsions: POLYGLYCERYL-2 SESQUIOLEATE and Soy Lecithin. However, after emulsifying for a while, phase separation occurred. Please check the formula.
Formula 1
Oil phase
Sunflower Oil 10%
Bee wax 2%
Cetyl palmitate 5%
POLYGLYCERYL-2 SESQUIOLEATE 4%
Water phase
Distilled water 68%
Glycerin 8%
Zinc Sulfate heptahydrate 5%
Preservative eco 1%
Recipe 2
Oil phase
Sunflower Oil 40%
Shea butter 20%
Soy Lecithin 10%
Water phase
Distilled water 28.5%
Zinc Sulfate 0.5%
Preservative eco 1%
Both formulas are hot blended at 70 degrees Celsius. After cooling down, they separate into two layers. I don't know how to solve this problem.
