Polysorbate 20 vs. 80

I know there was a thread on this in the last few days, but I have a question that is different, so forgive the repetition.

I make a natural all-purpose cleaner that has EOs in it as well as water. I've been selling it with the express directions to shake before use, but I want to go ahead and use polysorbate to emulsify the water and EOs, instead of making my customers do the work. I bought some P-80, and used it with some peppermint EO (equal amounts of EO and P-80) and added water. It emulsified great, but it's a really cloudy solution, and it has a slight soapy film on top of the water.

Since then, I've read that P-20 is probably what I'm looking for, instead of the 80. My main question is, will the 20 make a clear solution, and will I still have the tiny layer of foam on top? Will it be cloudy no matter which I use, or is it just the 80 that's doing it?

Thanks in advance.
