What is Glycerin and Where do you get it?
Glycerin can be obtained at most drug stores!
Glycerol, is a clear, ordorless, sweet tasting liquid in the alcohol class that is obtained by saponification* of certain fats and oils. It is used in many forms of manufacture of chellophane and alykyd resins and as a solvent and plasticizer. It is used in various soaps, candles and medications as well. When offered in solution, it is usually called glycerin.
Glycerol is most often obtained as a by product in soap production, but it is also made by other methods. It has two very unique properties: 1.) It will not disolve or be affected by most perol based solvents to include gasoline. 2.) It is inert and virtually harmless and readily mixes with water in any proportion.
Because of its harmless properties, glycerol is often used as a lubricant in food processing machinery. It's resistance to petro-chemicals make it ideal as a lubricant in gasonline and other volatile petro-chemical pumps.
It is slow to evaporate or crystalize and is used by some as a supplicant in leather and skin processing. The purest form of Glycerol in a nitrated form is commonly known as Dynamite.
It is available from chemical companies, Retail Druggists and from Hobby suppliers who carry soap making and candlemaking supplies.
* I know you knew this all along, but here is a definition for the other folks.....Saponification is the process through which fatty substances combine with alkali to make soap.
