Glycerol

Overview

Glycerol, also commonly known as Glycerin or 1,2,3-Propanetriol (CAS No. 56-81-5), is a fundamental and highly versatile polyol compound that plays a critical role across an astounding array of industries. As a clear, odorless, and viscous liquid, glycerol is naturally occurring in all animal and vegetable fats and oils, serving as the backbone for triglycerides. At CanCastor, our industrial experience confirms its indispensability as a humectant, solvent, plasticizer, emollient, and sweetener, leveraging its hygroscopic nature and excellent solubility.

Our extensive expertise in the supply chain of specialty chemicals ensures that CanCastor’s Glycerol meets the most stringent global standards, including USP, BP, EP, and FCC pharmacopoeial and food-grade specifications. This compliance guarantees the exceptional purity and consistent quality essential for sensitive applications. Our authority in the field is built upon rigorous adherence to international benchmarks like ISO 9001, coupled with a steadfast commitment to transparency in sourcing, primarily from sustainable, vegetable-derived feedstocks (often as a co-product of biodiesel production), upholding the highest levels of trustworthiness for our partners.
