Sodium Methylate / Soap?

Is making soap out of sodium methylate reacted glycerin any different than the usual sodium or potassium glycerin?

I would guess there is less fat and soap in the glycerin because of the better yield using methylate.

It will still be a concentrate. You may have to experiment a little to see how much NaOH to use per liter glyc. If you are using a short chain oil like canola or soy you will need to bind it with something if you want any sort of decent bar. The binding agent (preferably lard) will always have the same SAP value, so then what is left is to determine the SAP for the glyc.

The general base is 30gr/L NaOH for bars but you may have to lower that if the FFA count is down. That will give you a more soft soap, so upping the volume of the binding agent will be necessary or you will get rubbery soap. It will still work perfectly fine but just be a little "wierd".

You can either do it hit and miss based upon the base for methoxide reacted oil or use a calculator like the one on my website here:Universal SAP.
