Hi Todd, You could perhaps have added that soaps made from saturated fats such as stearin are harder than those made from unsaturated fats such as olein.
As a consequence, impure glycerol which contains stearin-based soaps (coconut, tallow etc.) should be more solid than a glycerol which contains olein-based soaps. (Provided of course that they are similar in concentration, dispersion etc. etc. etc.) Regards Michael Allen Thailand --- Appal Energy <[EMAIL PROTECTED]> wrote: > Crude glycerin does not solidify at room > temperature.
