Glycerin Technical Grade

Product Overview

Glycerin Technical Grade (CAS 56-81-5), chemically known as 1,2,3-Propanetriol or Glycerol, is a high-purity (typically 99.6%), clear, colorless, and odorless liquid. Characterized by its high viscosity and hygroscopic nature, this trivalent alcohol serves as a critical raw material in industrial formulations. With a chemical formula of C₃H₈O₃ and molecular weight of 92.09 g/mol, it exhibits robust stability and solubility in both water and alcohol, making it an essential solvent and humectant for manufacturing and processing environments.

Engineered for industrial applications, this technical grade product provides consistent density (approx. 1.261 g/mL at 25°C) and a high boiling point (290°C), ensuring predictable performance in heat-transfer fluids, chemical synthesis, and surface coatings. It is practically non-volatile, with a low vapor pressure that supports stability in open-system processing. This grade is specifically refined to minimize impurities, offering reliable assay values suitable for non-pharmaceutical and non-food grade applications such as paints, resins, and industrial coolants.

Safety & Handling

Glycerin Technical Grade should be handled in accordance with standard industrial hygiene practices. While not classified as a hazardous substance under GHS, appropriate Personal Protective Equipment (PPE) including safety glasses and gloves is recommended to prevent direct contact. The product is hygroscopic; store in tightly closed HDPE or glass containers in a cool, dry area to prevent moisture absorption. Ensure adequate ventilation during transfer. Refer to the Safety Data Sheet (SDS) for detailed spill cleanup and disposal protocols.
