Dear Prof. Yuri Mirgorod thanks a lot for your kind suggestion. Sir, I tried to dissolve my O-PEW in EtOH but unfortunately failed. I understand, my O-PEW could be different in number of ways from others which can dissolve in EtOH. However, cyclohexane (also xylene, but toxic) is working well to dissolve as well as making emulsion, where water phase consist of SDS in water. Thanks again
