What are the different uses of glycerin from biodiesel?
raw glycerol or glycerin is one of the by -products of biodiesel production. Raw glycerin is not suitable for most commercial applications due to a high level of impurities and requires further improvement before marketing. After clarification, purified glycerin can be used in the same applications as conventional varieties, including food and pharmaceutical products, cosmetics and chemical formulations. However, raw glycerin refining is expensive and the process of the process has forced biodiesel producers to look for commercially viable uses for a raw product such as composting, combustion, animal feeding and explosives. Improvement of raw glycerin removes methanol, free fatty acid, calcium, magnesium and sulfur and ensures minimal glycerol concentrations, glycerin active component, 80%. Pure glycerin refined from by -products on raw bionaFT is essentially the same as other means and can be used in similar applications. On the other hand, raw glycerin is used either by the wayas or is partially refined.
refined glycerin from biodiesel is used in a number of industries, including food processing, pharmaceutical production and chemical formulation. The food industry uses glycerin as a sweetener, solvent and thickener. It is also used as a moisturizing agent to maintain moist food and as a filler in many low -fat products. Pure glycerin from biodiesel is also included in many foods with low glycemic index (GI) because it has approximately the same caloric or food energy as table sugar but does not increase blood sugar.
The pharmaceutical industry uses refined glycerin from biodiesel in a range of medical and personal care products such as lubricant, moisturizing substances and an agent improving texture. These products include cough syrups, expectorants, toothpaste, skin care products and shaving cream. Soap, products PRGlycerin as an additive also have about hair care and personal lubricants. Glycerin is also commonly used as an agent for holding a tablet in formulation of fixed dosing medicines.
The chemical industry has several applications for purified glycerin from biodiesel. These applications include fuel additives such as glycerin acetate, part of surface coatings and as ingredients in artists. Glycerin is also found in the formulations of paper, dyes and inks and antifreeze.
raw or partially refined glycerin is used in a number of industries that do not require a high level of purity. These include explosive production, aerobic composting and a range of products for animals. Glycerin derived from biodiesel is also added to dust suppressing products and has been used as a basic combustion fuel pellet.
