　　Pharmaceutical excipient: As a solvent for injections (e.g., glycerol injection) and ointment bases (e.g., glycerin enema, utilizing hypertonicity to stimulate bowel movement).

　　Preparation of nitroglycerin (vasodilator, used to treat angina).

　　Chemical Industry

　　Raw material for synthetic resins (such as polyurethane foam, alkyd resins), used in coatings, adhesives, plastics, etc.

　　Production of surfactants (such as glycerol fatty acid esters), used in detergents and emulsifiers.

　　As an antifreeze agent (lower toxicity than ethylene glycol), used in automotive coolant and laboratory low-temperature baths.

　　Other Applications
