How much egg yolk can I use, before disaster, to make soap with cocosnut and possibly olive oil:?

Hi there!

I am trying to make a soap with egg yolk in its formula.

I have tried some recipes I found, which resulted in nice soaps, but they all had very low % (in weight) around 1 egg yolk per 44 oz. of other oils (coconut and olive) and the difference from soap with same oils without egg yolk, although noticeable is rather subtle.

I would like to try making a soap with as much egg yolk as it is possible to obtain a reasonable soap and from there I would like to progressively reduce the amount of egg yolk in search of an optimal value.

I also wonder whether there is some naive mistake in my idea. I am neither a chemist nor a experienced soap maker, I only make pure coconut soap for dish washing (and eventually some clothes washing).

Use try and error.
