I have been testing 2 types of oil with this surfactant but did not managed to get a one phase mixture even after adding water with small concentrations. I tried using Tween 80 as the surfactant and carrier oils such as olive oil and palm oil but still did not succeed.
Do I have to change the surfactant used or add a co-surfactant to it? Do I have to change the carrier oil used? And if so, which one would be soluble with the surfactant used?
Would gladly appreciate all answers here, thank you very much for your help.
Best wishes,
Fatin Farhana.

Mani Sharma thank you very much! I really appreciate the help Sir.
Hi.
You don't say if you want to make microemulsions (self-emulsifying) or nanoemulsions (using milling by homogenization or a microfluidizer). For microemulsions, try Tween-80 and Cremophor EL in a 2:1 weight ratio to start, and see if peppermint or spearmint oil works for you. If you are using instruments to mill the emulsions, try castor oil in a 1:1 wt ratio with the Tween 80.
Hope this works... Good luck.
Hello,
In our work, we have developed microemulsions with Tween 80, and as oily phase, we have used pine oil and sunflower oil. Both of these oils resulted in good results in the microemulsion. Also, I believe you should try a solution of water and glycerol (1:1) as the aqueous phase.
I hope it helps.
Raphael Ribeiro da Silva I see, really appreciate it. thank you sir
Robert A Bellantone hello sir, I am making nanoemulsion using the tween 80 as the surfactant. Thank you for the reply Sir
'carrier oils such as olive oil and palm oil' this suggest that you want to make a water-in-oil emulsion? - then Span type surfactants are much more suitable. Nanoemulsions as all real emulsions are 2 phase, nevertheless you should be able to solubilize a small amount of water into the oil surfactant mixtures.
Titus Sobisch thank you sir, i'll try using span as the surfactant
