Chemical database: 12. Glycerin

Glycerin (C3H5(OH)3) is a colorless and viscous liquid without any specific smell, but with a sweet taste. It has many uses in the pharmaceutical industry. Density = 1.261 g/cm3. Melting point = 18°C. Boiling point = 29°C. Glycerin is one of the byproducts in the production of biodiesel and in the production of soap. It is used in medicine, in the pharmaceutical industry as a lubricant and a solvent (instead of ethanol), as an antifreeze and sometimes even as a laxative. Glycerin can also be found in cough syrups, in various skin care products, in toothpastes, soaps and shampoos. It is also used in the food industry and in the production of explosives (nitroglycerin).

Pure glycerin can be bought in most drugstores/pharmacies, at a price of around 1.5€ per 100 ml (in the Croatian market). It can also be ordered in greater amounts (1000 ml). Glycerine can also be bought from chemical selling companies. Unfortunately, they mostly don't sell smaller quantities, so a drugstore/pharmacy would probably be the best place to look for this substance.
