Glycerol Formula

Glycerol Chemical Formula

Glycerol is also referred to as glycerin, which is a basic polyol compound. Glycerol is a colorless, odorless, and viscous liquid that is non-toxic and sweet-tasting. In certain lipids, the glycerol backbone is found which is referred to as glycerides.

The chemical formula for Glycerol is: C3H8O3

Glycerol is a polyol, a compound that contains more than one group of hydroxyls. There are three hydroxyl groups in its chemical structure, which are -OH groups bound to the carbon atoms. Glycerol has 3 Carbon atoms, 3 Oxygen atoms, and 8 Hydrogen atoms.

Glycerol Structural Formula: 

Glycerol, with three carbon atoms and three hydroxyl groups, is a trihydroxy sugar alcohol. It is an organic polyol compound with the IUPAC name of 1, 2, 3-Propanetriol because of the inclusion of various hydroxyl groups and carbon atoms. Because of the hydroxyl (-OH) groups bound to the carbon atoms, glycerol is soluble in water. The hygroscopic aspect of glycerol is also responsible for these hydroxyl groups, which ensures that it quickly retains or takes up water.

Glycerol Molecular Formula:

The Molecular formula of Glycerol is referred to as C3H8O3 OR CH2OH-CHOH-CH2OH.

The molecular weight of glycerol is 92.09 g/mol. Glycerol is a triol with a propane structure placed by hydroxy groups at positions 1, 2, and 3. The glycerol density is 1.261 g/ml. Its boiling point is 290 degrees Celsius and 17.8 degrees Celsius is its melting point. These values mean that glycerol is denser than water (because the density of water is 1 g/mL), its boiling point is higher than water (the boiling point of water is 100 degrees Celsius) and its melting point is higher than water (water has a melting point of 0 degrees Celsius). Due to the capacity of the polyol groups to form hydrogen bonds with water molecules, glycerol is easily soluble in water. With a specific gravity of 1.26, glycerol is significantly denser than water. That implies that it will fall to the bottom when glycerol is poured into a container of water. Owing to its solubility, however, glycerol can form an aqueous solution over time and with moderate agitation.


The glycerol which is also referred to as glycerine having a formula C3H8O3. In the food industry and personal care products, glycerol is mainly found. It is also used to create explosives as antifreeze and also as one of the ingredients. We will address the different uses of glycerol in this segment. Glycerol is also used as a raw material for Hydrogen Production.

FAQs (Frequently Asked Questions)

1.Can We Use Glycerol on Our Skin?

Yes, we can use glycerol on our skin. Glycerin is a moisturizing agent, a type of moisturizing agent that draws water from deeper layers of your skin and air into the outer layer of your skin. Glycerol is widely used with occlusives, another form of moisturizing agent, in skincare products, to capture the moisture that it draws into the skin.

2. Which Foods Contain Glycerol?

Pre-cooked pasta rolled oats, breakfast cereals, rice or tapioca pudding, breading or batters, pre-cooked rice products, and baked goods are all possible sources of glycerin. Processed fruits and vegetables (dried or canned vegetables or fruits, pre-cooked vegetables) also consist of glycerol.

3. Can We Make Glycerol at Home? Explain.

Yes, we can make glycerol at home. Add one cup of coconut oil and olive oil to a saucepan. Keep it low and gradually add 1 teaspoon of lye and 1 cup of water. For 15 minutes, heat the mixture and keep stirring until the mixture thickens. Add 1/2 cup salt as tracing reflects in the pan and allow the mixture to cool.
