Which oils saponify to a salt that has a natural pH that is under 10 (say around 9.7) ?

Is there a soap recipe whose soap has a natural pH that is under 10 (say around 9.7) ?
I know that one can add a mild acid to the finished soap to lower the pH. But I was wondering if a combination of certain oils and fats will accomplish this without having to add a mild acid afterwards.
Why I am hung up on the pH:
===================
I regularly do the zap test. I'm okay with the zap test. I just feel more comfortable if the pH of my soap were between 7 and 10 (which is the okay range for our soaps). One of my soaps wasn't. The soap passed the zap test, but the pH was over 11! People have said that if the pH is too high, it can have adverse affects on the skin over time. Experienced experts debate this skin issue, I don't know who's right, so I want to play it safe. I also don't want to rehash the skin debate; I'm sure people are tired of it. Since, people have talked about how the natural / intrinsic pH of the fully saponified soap (w no excess lye) varies depending on the recipe, I thought I'd ask the above question.
