WATER IN ESTER EMULSION

WATER IN ESTER EMULSION

WATER IN ESTER EMULSION

(OP)
Hello everyone!

For last month I have been struggling to get a stable (without separation) emulsion composed of ester (triacetin) and water. Unfortunately I am not a skilled person in the area. I have been testing different emulsifiers to get water-in-oil emulsion type. The ratio between the ester and water is 20:1, and water phase (about 70% is water) contains protein (about 1%), sodium chloride of 10% and sorbitol of 20%. Does anyone have experience with emulsifying esters and water and could say something about possible methods that I could apply? I tried such nonionic emulsifiers like Tween 80, Span 80 using different concentration, below and above CMC - 1%, 5%, 10%, 15%, several surfactants for textile industry, and I also used the blend system using mixtures Span/Tween 80 to get the wide range of HLB numbers (4.7-15) but to no avail. For agitation, which I know may play a crucial role, I have not exceeded 500 rpm (IKA RW20 overhead stirrer).
