Glycerine is a clear, syrupy liquid with a sweet taste and is extremely hygroscopic (water-attracting) in pure form. It is produced by the reaction of oils and fats with water, and is separated and purified to make a high quality product suitable for a wide range of end uses.
Glycerine has important industrial applications, for example as a polymer building block in the production of alkyd resins and polyurethanes for use in paints, inks and coatings. Glycerine is also a raw material for the manufacture of many different types of chemical intermediate, including solvents, plasticizers and surfactants. The water-binding tendency of glycerine is exploited in the preparation of anti-static and anti-fogging additives.
In foods and beverages, glycerine functions variously as a humectant, solvent, preservative and sweetener. It is also used in skin creams, body washes, shampoos and soaps for its lubricating, moisturising and clarifying properties. Due to its benign nature it can be safely ingested, and is used to sweeten and thicken cough syrups, elixirs and expectorants, toothpastes and mouthwashes. In liquid detergents, glycerine has an important role as viscosity regulator, solvent and clarifying agent.
PRICERINE™ 9095 is Croda's pharmaceutical grade vegetable glycerine (99.5%). In 2005, this product was the first vegetable glycerine to be awarded a Certificate of Suitability by the European Directive for the Quality of Medicines (EDQM). The role of a Certificate of Suitability is to certify the compliance of a material with the requirements laid down in the relevant monograph of the European Pharmacopoeia. Pharmaceutical ingredients for which a Certificate of Suitability has been granted are permitted for use in medicinal products.
