Glycerol CAS#56-81-5

Glycerol CAS#56-81-5

Exceptional Hygroscopicity & Moisture Retention:Highly hygroscopic, it absorbs water from the air, making it ideal for moisturizing in cosmetics, pharmaceuticals, and food preservation without altering pH (5.5–8).


High Thermal Stability & Safety:Stable up to 290°C, low flammability (flash point 160°C), and low toxicity (oral LD₅₀ >20 mL/kg in rats), suitable for high-temperature processes.


Sustainable Utility:Derived from biodiesel byproducts, it’s cost-effective in agriculture (livestock feed), medicine (enemas), and eco-friendly antifreeze, reducing waste and resource use.

Quality Assurance

Rigorous quality control and full regulatory compliance assured.

Sustainable Development

Sustainable processes cut waste, lower emissions, and save costs.

Specialty Solutions

Tailored fine chemicals that enhance efficiency and outcomes.

Chemical Manufacturer

A trusted manufacturer capable of stable, high-volume production and supply.

ABOUT THE PRODUCT

Product Description

Product Description-Glycerol CAS#56-81-5


Glycerol (also known as glycerin) is a colorless, odorless, sweet-tasting viscous liquid in its pure form. It has a boiling point of 290°C, a melting point of 17.9°C and a relative density of 1.2613. Fully miscible with water in all proportions, anhydrous glycerol has strong hygroscopic properties.

Product Applications-Glycerol CAS#56-81-5


It is a raw material for the production of nitroglycerin, acetic acid glycerol, surfactants, flavors, alkyds and ester gums. It can be directly used in antifreeze, cosmetics, inks, etc.


It can be used as water-retaining agent (used for bread and cake); carrier solvent (used in flavor, pigment and water-soluble preservative; thickener (used for drink and wine formulation); plasticizer (candy, desert and meat product); sweetener, gas chromatographic fixative.
