Huh? I got a good laugh out of this and I don't know why! It's just a weird statement. I'm still laughing! Maybe I'm just tired. Note: being tired is not an interesting state to be in by itself. It has to be injected with caffeine before it lends itself to fits of laughter, so it's safe to be tired in a library, church, or school board meeting.

"The process of removing the glycerin from the soap is fairly complicated (and of course, there are a lot of variations on the theme). In the most simplest terms: you make soap out of fats and lye. The fats already contain glycerin as part of their chemical makeup (both animal and vegetable fats contain from 7% - 13% glycerine). When the fats and lye interact, soap is formed, and the glycerin is left out as a "byproduct". But, while it's chemically separate, it's still blended into the soap mix."


So there really is pork glycerin! I love pork!!!

Mama Bear uses glycerin in her soaps and they are absolutely some of my favorites for the lather they give as well as the amazing scents.

I have mixed the marauders citrus with my lime shave cream for a super lather, but now I think the glycerin in the soap may make it an uber lather. Either way, it gave an amazing shave with many of the properties listed.

After a little hunt for some, I found a bottle of 100% vegetable glycerin at a health foods store along with some pure alum block "crystal" deodorant that I couldn't seem to find anywhere. It's pretty cool, just an alum block shaped into a stick of deodorant in a little plastic case like other deodorants, says it'll last a year on the packaging.

Funny how so many things are related. I drive a VW Jetta with a diesel engine. iv recently been looking into making bio diesel for cost and environmental reasons. take a guess at the biggest bi product of making bio diesel. yup...Glycerin! if anyone knows anyone in there town who drives around to all the local restaurants and takes there used cooking oil, chances are... there making bio diesel and probably have buckets of glycerin that they would be happy to get rid of. a post up on craigslist should put you in touch with all the glycerin you could ever want.

The used cooking oil has been broken down by the cooking process sufficiently that no further refinement is required to use it as diesel... you simply filter out the large particles, and drive...

You can use straight used cooking oil in a diesel engine however good luck starting it cold. what i am referring to is true bio diesel. its filtered veg oil mixed with methanol/ lye to a ratio determined by titration. and as we know through soap making lye and oil (or any fat) produce glycerin. i may be new to this forum but i do have forum educate, and this tread pertains to glycerin and not alternative fuel methods, however if you would like to debate further on bio diesel id be more that happy to continue in a separate thread. my intentions were only to give a potentially free source of glycerin to anyone interested instead of paying 5+ dollars for a little tube of it.

overly simplified biodiesel possess:

(1) Coarse filtration of oil and drainage of any water present (2) Sample oil and perform titration - determine quantity of catalyst (3) Measure the reactants (4) Dissolve NaOH into methanol (5) Mix the reactants (6) Allow glycerol to settle (7) Drain glycerol (8) * Further processing e.g. washing / drying / additives (9) Filtration of biodiesel


*Glycerol and glycerin are the same compound.*

I was able to find an 8 oz bottle of vegetable glycerin $10.99 from Whole Foods and also purchased a small bottle with eye dropper applicator for $2.79. Put in three drops of glycerin into my Kiss My Face save soap. Wow, it really thickened my later to a paste/frosting like lather. My straight razor gave me the best shave ever. Smooth as a baby's bottom. This will be part of my daily routine. This is probably a year's supply but worth every penny in MHO.

I used to use glycerine when I was using store bought soaps but I worked with my wife on a glycerine based recipe that uber lathers with nothing having to be added to it. It's alot easier and makes for more counter space. LOL
