Cold process O/w thin lotion stability issue
I am working in this basic thin o/w lotion, the problem is after a few hours it separate in two parts. a cream like in top and water like in bottom.
I use Hlb system.
It is cold process.
Here is ingredients
Olive oil %9.3 Hlb 7
Glyceryl caprylate %0.7 Hlb 6.6
Hlb of oil phase= 6.97
Water to %100
Polyglyceryl-4 Laurate %53.38 Hlb 10
Glyceryl oleate %46.62 Hlb 3.5
This mixture gives Hlb 6.97
I used %4 and %5 emulsifier mix but separated.
I mix Polyglyceryl-4 Laurate in water and glyceryl oleate in oil and then add oil to water while mixing with stick blender.
What is your suggestions to stabilize it.
Thanks in advance
