Hello everyone,

I am working on formulation of nanoemulsion of crude plant extract which is hydrophobic, however after 24hr I see it is separated in two phases. I tried with different surfactant (lecithin, quillaja saponaria, tween 80 and span 80), oils (olive, coconut and almond) and also varied sonication time.

Could you please help me to get stable nanoemulsion.

Looking forward to get some interesting suggestions

Thanks in advance
