Do I need an emulsifier? If so, which is appropriate? - I would say no, Sepimax ZEN is your emulsifier at this input. You can lower it and add some other non-ionic emulsifier to make it more creamy (less gelly). However only stability testing will answer your question.
Is it possible to make a transparent gel which contains oil phase? I would say no. Once you introduce lipid (not solubilised) it will turn milky.
What can I do to achieve my intended result? Remove oil or solubilise it.

Thanks very much Paprik. I very much appreciate your straight to the point response.

The addition of Curcylic 40 might have lowered the pH too much for the Sepimax to handle. You can check what pH the Curcylic 40 is in normal distilled water, and perhaps adjust the pH of the formed gel before adding the Curcylic 40.
If you use high percentages of oils then making a transparent gel won’t be possible. Though if you still prefer to add small percentage of lipids, then using a solubilizer will help.

@SonOfMan I agree with @Paprik. I believe your Anti acne formula ingredient is the one responsible. Now, there are actually very few ingredients that demonstrate anti acne properties, and those make your product a drug rather than a cosmetic. So, if you are addin the Anti acne formula ingredient just for claim purposes, reduce it to the least amount possible (for example, 0.01%).
