Glycerol, a trihydric alcohol, is a clear, water-white, viscous, sweet-tasting, hygroscopic liquid at ordinary room temperature above its melting point (18.17 °C); its structural formula is the following:
Glycerol occurs naturally in combined form as glycerides in all animal fats and vegetable oils, and is recovered as a co-product when these fats and oils are saponified in the process of manufacturing soap, when they are split in the production of fatty acids or when they are esterified with methanol in the production of methyl esters.
The term “glycerol” applies only to the pure chemical compound 1,2,3-propanetriol, while the term “glycerine” applies to the purified commercial products normally containing more than 99.5% of glycerol. Several grades of glycerine are available commercially; they differ in their glycerol content and in other characteristics such as colour, odour and impurities profile.
All our products are manufactured exclusively from vegetable origin crude glycerines and no animal origin materials are used during the refining process. It follows that our Vegetable Origin Refined Glycerines are safe with respect to Transmissible Spongiform Encephalopathy.
