What is the Difference Between Glycerine and Glycerol?

🆚 Go to Comparative Table 🆚

Glycerine and glycerol are both names for the same molecule, propane-1,2,3-triol, which is a simple triol compound. They are chemically the same, with the same chemical formula (CH2OH-CHOH-CH2OH). The primary difference between the two terms is their purity and usage:

  • Glycerol: This term is used for the pure chemical compound, which can be produced synthetically or obtained from natural sources. It is often used in laboratory settings and as a starting material for the production of other chemicals.
  • Glycerine: This term refers to the commercial name of glycerol, which is not pure and typically contains around 95% of glycerol. It is used in various applications, such as food sweeteners, preservatives, and personal care products.

In summary, there is no significant chemical difference between glycerine and glycerol, as they both refer to the same molecule. The main difference lies in their purity and the context in which they are used.

Comparative Table: Glycerine vs Glycerol

Glycerol and glycerine are essentially the same compound, with glycerol being the more accurate chemical term. They are both colorless, odorless, viscous liquids that are sweet-tasting and non-toxic. Here is a table summarizing their properties:

Property Glycerol/Glycerine
Chemical Formula C3H8O3
Class Triol compound
Appearance Colorless, odorless, viscous liquid
Melting Point 17.8°C
Boiling Point 290°C
Density 1.26 g/cm³
Solubility Miscible with water, hygroscopic in nature
pH Neutral (around 7)

Both glycerol and glycerine have antimicrobial and antiviral properties and are widely used in wound and burn treatments. They are also used as a sweetener in the food industry and as a humectant in pharmaceuticals. Glycerol is a component of triglycerides and is commonly found in lipids.
