Properties of Glycerol

Glycerol, also known as glycerin or glycerine, is a colorless and odorless liquid.
It has a sweet taste due to its chemical structure and is often used as a sweetener in food products.
Glycerol has a relatively high boiling point of around 290°C (554°F).

Freezing Point of Glycerol

Glycerol has a low freezing point, approximately -37°C (-34.6°F), indicating it remains in liquid form at lower temperatures compared to many other substances.

Solubility of Glycerol

Glycerol is highly soluble in water and can dissolve a variety of substances, including salts and sugars.
It can also dissolve in alcohol, but its solubility is not as extensive as in water.
Glycerol can dissolve more substances than either water or alcohol, particularly certain organic compounds.

Uses of Glycerol

Glycerol is utilized in the pharmaceutical industry, cosmetic products, and as a humectant in food to retain moisture.
It is also employed in the production of soap, as well as in various industrial applications.

Chemical Properties

The chemical formula for glycerol is C3H8O3, which accounts for its physical properties and interactions with other molecules.
Glycerol's hygroscopic nature allows it to attract and hold moisture from the air, enhancing its use in various formulations.
