Glycerol is a naturally occurring chemical and is used as a medicine in the treatment of burns and wounds. It is a clear colourless, odourless, sweet-tasting liquid that is viscous in nature and belongs to the alcohol family of organic compounds. It is generally obtained from plant and animal sources where it occurs in triglycerides.
Glycerol is present in a small amount in human tissues in the form of trivalent alcohol. It is a volatile liquid and if it is left outside in contact with the environment it will vaporize even at room temperature. Glycerol is biodegradable and when exposed to the environment it will distribute itself in air, soil, or sediment.
Along with these advantages, there are some disadvantages of glycerol, It can cause headaches, dizziness, nausea when taken directly. It can also cause a skin rash, redness, or burns to the skin if applied directly. It can cause serious damage to RBCs if injected. Therefore, the use of glycerol should be done under medical supervision only.
The molecular formula of Glycerol is: C3H8O3
It is a trifunctional compound i.e. three alcohol groups are present on three carbon atoms and its IUPAC name is 1,2,3− propane triol.
Density: 1.26 g/cm³

Glycerol is commonly used to relieve occasional constipation, improving hydration and performance in athletes, and improving skin conditions.
It can be used for the treatment of wounds and types of burns. it is to be remembered that glycerol cannot be used for the treatment of third-degree burns.
Another important application of glycerol is in blood banks, where the compound is employed for the preservation of RBC before they are frozen for storage.

Other Uses of Glycerol:
In the food industry, glycerol is used in order to retain moisture.
A mixture of water and glycerol can be used to preserve the leaves of certain plants.
Athletes use glycerol to keep themselves away from becoming dehydrated.
It is widely used as a raw material in the production of nitroglycerin.
It is used as softening agents in baked goods, plasticizers in shortening, and stabilizers in ice cream.
Glycerol is also used commonly in the film industry during the filming where water is involved mostly. In those situations, glycerol helps stop the areas from rapidly drying out.
It is used in making many modern protective coatings like automotive enamels and exterior house paints.
Did You Know?
Glycerol and glycerin are two different solutions that have the same chemical compound but their nomenclature is different.
Glycerin is the commercial name of glycerol that contains 95% of glycerol. Glycerin cannot be used interchangeably with glycerol. Glycerin is a less pure form of glycerol. Glycerin is widely used in cosmetics, other than fragrances it is the most used product in the cosmetic industry. There are numerous products that include glycerin in them, especially in moisturizers and lotions. The pure form of glycerin is readily available in the market and people purchase it for use directly.
