The one I find ironic is "use your glycerine to make soap", as if glycerine is a component, rather than a byproduct, of soap manufacture. It's true that traditional soapmakers leave the glycerine in there, but that's largely because it's so hard to remove it. It's also true that the glycerine phase left over after making biodiesel will wash things, but that's because of the SOAP in there, not because of the glycerine. A LITTLE glycerine in your soap makes it softer and a better emollient, but I get much better results with half tallow and half extracted FFA's. That makes for less glycerine and better soap, but doesn't help with glycerine disposal :-) I regard the glycerine as a total nuisance, but since it's just a simple sugar and quickly biodegrades, I don't hesitate to compost it or flush it, once the soap and alkali have been neutralized. ------------------------ Yahoo!
