What is glycerin?
Glycerol (or glycerine, glycerin) is a simple polyol compound. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature. The glycerol backbone is central to all lipids known as triglycerides. Glycerol is sweet-tasting and of low toxicity.
What is glycerin made of?
Glycerin has the molecular formula C3H5(OH)3. It consists of a chain of three carbon atoms such that each carbon atom is bonded to a hydrogen atom (H+) and a hydroxyl group (OH-). Each of the two terminal carbon atoms has an additional hydrogen atom so that all three carbon atoms have a total of four bonds. Carbon has a valence of four, meaning that it has a tendency to form four bonds.
Fatty acids are a class of compounds that are essentially a long chain of carbon atoms attached to various combinations of oxygen and hydrogen atoms. Each fatty acid molecule ends with a carbon atom that forms a double bond to an oxygen atom and a single bond to a hydroxyl group. This group has the formula COOH- and is known as a carboxyl group.
Plants and animals use glycerin and fatty acids to make triglycerides, which are the primary component of fat. The carboxyl end of each fatty acid reacts with the hydroxyl group on each carbon atom of a glycerin molecule. This results in each fatty acid molecule being bound to a carbon atom in the glycerin molecule. This process also liberates a molecule of water for each fatty acid molecule for a total of three water molecules.
What is glycerin used for?
Drugs - Glycerin is widely used to manufacture:
* Ear infection remedies
* Cough remedies
Foods and Beverages - Glycerin is used to moisten, sweeten or preserve food and drinks such as:
* Soft drinks
* Meat and cheese
* Dry food
Cosmetics and Toiletries - Because of the non-toxic nature of glycerin, it is used in cosmetics and toiletries like:
* Skin creams and lotions
* Pre-shaving lotions
* Make up
Tobacco - Glycerin is also used in tobacco to prevent the breaking and crumbling during the processing of cigarettes. It also adds some kind of flavor to the chewing tobacco. It is widely used to manufacture cigarette filter tips as well.
Paper and Printing - It is used to soften and reduce the shrinkage during paper manufacturing as well as in:
* Grease proof paper
* Food wrappers
* Printing ink
Textiles - Glycerin is used in textiles to soften the yarn and to lubricate fibres of different kinds. It is also used:
* As a lubricant for food processing
* To manufacture resin coating
* To add flexibility to rubber and plastic
* As a building block in manufacturing flexible foams
* To manufacture dynamite
* To create component that is used in radios and neon lights
Where can I buy glycerin?
You can buy online here at Where Can I Buy Glycerin, a division of ChemWorld. Our glycerin stocks are are manufactured to US FDA standards. Plus, it bears the USP mark, guaranteeing that it is food-grade and is non-toxic. All products featured on site are in stock and ready to be shipped within 24 hours.
How do I store glycerin?
Use smoked or colored glass or plastic with the glycerin to avoid excess exposure to the light; repeated heating can break down the chemical bonds in the glycerin. Pour the glycerin into the container, making sure that it can sealed tightly, then store in a cabinet or drawer.
If your glycerin seems to dry out, take the lid off and let in some air. The glycerin will pull moisture from the air and rehydrate. Or you can add water a few drops at a time to help rehydrate the product.
The best storage temperature is 65 degrees Fahrenheit to 75 degrees.
