Description

Glycerol CAS NO 56-81-5 is a simple polyol compound, also known as glycerin, that serves as a fundamental building block and versatile processing aid across numerous industries. Its unique combination of hygroscopicity, viscosity, solubility, and non-toxic nature makes it an indispensable ingredient for product formulation and manufacturing. This high-purity chemical is essential for producers in the pharmaceutical, food & beverage, personal care, and chemical synthesis sectors seeking reliable quality and consistent performance.

Application

• Pharmaceuticals: Used as a solvent, humectant, sweetening agent, and excipient in syrups, elixirs, cough medicines, and topical preparations (ointments, creams).
• Food & Beverage: Functions as a humectant, solvent, sweetener, and bodying agent in confectionery, baked goods, dairy products, and liqueurs (FCC grade).
• Personal Care & Cosmetics: A key humectant and moisturizer in skin care products, lotions, soaps, toothpastes, and hair care formulations.
• Chemical Intermediate: A crucial raw material for the synthesis of alkyd resins, polyurethanes, explosives (nitroglycerin), and esters.
• Industrial Applications: Acts as an anti-freeze agent, lubricant, plasticizer for cellophane, and processing aid in the tobacco and textile industries.
• Laboratory & Research: Employed as a reagent, cryoprotectant, and buffer component in biological and chemical research.

Quality Control

Our Glycerol is manufactured and tested under a strict quality management system to ensure it meets the rigorous requirements of our global customers. We offer various grades, including USP, Ph. Eur., and FCC, to suit specific application needs. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each batch to guarantee supply consistency and regulatory compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed when not in use to prevent absorption of atmospheric moisture. Keep away from strong oxidizing agents.
