Glycerin, also known as Glycerol or 1,2,3-Propanetriol is a simple polyol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic with chemical formula C3H8O3.
Glycerin Chemical Structure Composition.
- Glycerol can be produced by various routes from propylene.
- Gycerol is a waste product of biodiesel from fats
- Triglycerides can be saponified with sodium hydroxide to give glycerol and fatty sodium salt or soap.
The main sources are soybeans, rapeseed, palm oil (RSPO/MB) and animal-derived tallow.
- Crude Glycerin: glycerol content above 80%, high water content and presence of MONG (Matter Organic No glycerol). Brown. Main use is energy intake in cattle.
- Technical Glycerin: glycerol content until 95%, low water content and the presence of MONG. Gray. Used in all types of intermediate industrial chemical processes.
- Glycerin USP/ PhEur: glycerol content above 99%, color less, transparent and MONG and water minimum content. Used in the cosmetics industry, personal care and pharmaceutical industries.
- Glycerin E422: as food Additive.
- USP – Kosher – Hallal
Glycerin is used in the food, pharmaceutical, cosmetic and coating industries as a chemical intermediate, perfuming, skin protecting, humectant, solvent, sweetener, thickening agent (viscosity controlling), emollient or conditioning agent.
