When making your own Bio-D, the entire chemical process is to remove the glycerides from the oil. You will get 2 distinct layers. Bio-Diesel, and glycerine.
What to do with the glycerine?
Here is some examples of what glycerine and glycerine based products can be used for:
It is obtained entirely from natural, renewable resources. Glycerine is used as an ingredient in cosmetics, medicines, toothpaste, esters, liquid soaps, tobacco products, and food products. It is also used extensively as an intermediate in the production of polyester, polyurethane, and alkyd resin formulations.
Adhesives
humectant in water-based adhesives
Chemicals - Surfactants
glycerol esters
Chemicals - Textile
glycerol esters
Coatings & Inks
dispersant
Food Ingredients
In the production of food, it is used as a solvent, a moistening agent (for example, in baked goods), and an ingredient in syrups. In flavoring and coloring, glycerol acts as a solvent and its viscosity lends body to the product. With icings and candies, glycerine prevents crystallization of sugar. It improves the texture and allows the use of less sugar, in ice cream.
Lubricants & Greases
Glycerol can be used as a lubricant in situations where an oil would fail. It is recommended for use in oxygen compressors because it is more resistant to oxidation than mineral oils. Cosmetic, food, and pharmaceutical manufacturers may use glycerol instead of oil for a lubricant; especially, when the products come in contact with the lubricant. In the textile industry, glycerol is commonly used in connection with so called textile oils, in spinning, knitting and weaving operations.
Miscellaneous Uses
Glycerine has many other uses, such as in antifreeze fluids for automatic sprinkler systems, defrosting for glass, de-icing, and in electrolytic fluids for making galvanized cloth and lightning arrestors. It is found in cement compounds, particularly in glycerinlitharge cements for tubs and sinks, valve repair, still and distilling unit repair and anti-acid corrosion, pipe joint cement, furnace cement, and rethreading compounds. Other uses include embalming fluids, masking and shielding compounds for paint spraying, soldering compounds, high pressure rod packing, lubricants for air brakes, the manufacture of mercury thermometers, engine gauges, electrical equipment, and oil refinery equipment. Glycerine is found in cleansing materials such as soaps and synthetic detergents. It is used as a wetting agent in emulsifiers, wax emulsions, and skin protectives. In laboratory and research work glycerine is utilized in the manufacture of reagent chemicals, basic dyes, and miscellaneous chemicals and insecticides; in asphalt compounds, coal-tar thinners, ceramics, photographic products, fire retardants, modeling clay, leather and wood treatments and adhesives.
Personal Care
In cosmetics, glycerine is a favorite in keeping the skin soft and is used in body and shaving creams. It is the basic material in which toothpaste is formed and preserves the desired smoothness and viscosity of the paste.
Pharmaceuticals
Glycerine is used in cough medicines and anesthetics, for ear treatments, and in bacteriological media.
Plastics - Additives & Lubricants
Sheets and Gaskets
Glycerine acts as a plasticizer and a humectant when used in the production of sheets and gaskets made with ground cork.
Tobacco
Glycerine is used as a humectant (a moistening agent), in tobacco products. In processing tobacco, glycerol makes up an important part of the casing solution, which is sprayed onto the tobacco before the leaves are shredded and packed. When processing chewing tobacco, glycerine adds sweetness and prevents dehydration. It is also used as a plasticizer in cigarette papers.
Urethane Polymers
Glycerol is an important and essential building block in polyethers for urethane polymers. Glycerol based polymers have found some uses, such as in rigid urethane foams.
Wrapping and Packaging Materials
Meat casing and special types of papers, need a plasticizer to give the products pliability and toughness.
before you start taking glycerine baths for your good comlexion, make sure you have evaporated all of the Methanol out of it, and also PH test it to make sure there is no unreacted LYE still in suspension.
Once you have a PH of 7 (neutral), you can use it around the garage as a great hand cleaner!

I found out yesterday it's used in astroglide... [img]/ubbthreads/images/graemlins/shocked.gif[/img]

You know the history of astroglide? It was originally invented by NASA. They weer looking for something they could coat the bottom of the spaceshuttle with to help reduce friction during re-entry. (Hmmm, sounds like its doing its job just fine, but in a different arena!!).
It obviously didnt work as intended and is now sold for "other" purposes.
Forgotton, I just started brewing and want to make degreaser for my shop. We work on our trucks whenever we can so we use a lot of degreaser. What is an easy way to bring the ph in line? Add an acid like acetic?

A degreaser in your shop for cleaning equipment should be in the higher pH range. Most equipment degreasers are 12.5 to 13.2. Skin starts to burn at 12.2 and some shampoos are up around 11.5.
Keep in mind if it will take the grease off equipment and the grease off your hands, it will take the natural oils out of your skin. You may need to use some lotion if dryness develops.
As for the glycerine, I've never worked with it to know how it works as a degreaser without the caustic.
