So ... substituting vinegar for water (with the proper increase of lye) creates sodium acetate, which helps to harden the soap. Adding yogurt creates sodium lactate, which also hardens the soap (this I've done).
I prefer to OHP my soaps, and the yogurt/sodium lactate not only adds to the hardness of the finished soap, but also helps keep the hot/gelled soap fluid enough to mold nicely. My question is ... does anyone know (or have experience) if the vinegar/sodium acetate also helps with the fluidity of the soap before it hardens?
