Refined Glycerine 99.7% Min Vegetable (Brazil Origin)

Brief Overview
Glycerin, sometimes referred to as glycerol or refined glycerine, is a simple sugar alcohol with three hydroxyl groups, which are responsible for its water-soluble and hygroscopic characteristics. With a high boiling point and viscosity, this liquid's colorless, odorless, and crystal-clear appearance indicate its inherent sweetness and low toxicity. It comes from petrochemical feedstock and is used in food, medicine, cosmetics, personal care products, and biodiesel manufacturing, among other industries.
Manufacturing Process
Threshing
The initial phase of palm fruit processing entails carefully eliminating the main stem and attached spikelets.
Sterilization
The palm fruit undergoes steam sterilization at elevated temperatures to prevent oil oxidation and hydrolysis, assisting in separating the fruit's walls from the kernel, gum, and resin due to increased internal moisture.
Digestion
Mechanically mixing and breaking down sterilized palm fruits occur at heightened temperatures, releasing palm oil from the pulp and cells with additional heat for smooth blending.
Pressing
Processed palm fruit undergoes pressing in a hydraulic machine to extract palm oil, gathered for subsequent processing.
Oil Clarification
Post-extraction, the oil undergoes purification with hot water, initiating a separation process and filtering particles to establish a clear demarcation between water and oil layers.
Deacidification
Solvent extraction with methanol is applied to eliminate free fatty acids, augmenting the oil's shelf life and averting oxidation and undesirable odors.
Saponification and Transeferication
Hydrolysis under high pressure and temperature decomposes deacidified palm oil into fatty acid and glycerol/glycerine chains. Although glycerine is now prepared for extraction, further refining is necessary before designating it as refined glycerine.
Glycerin Pre-treatment
Diverse separation techniques are employed to refine the combination of glycerine and fatty acid chains. Distillation extracts glycerine, utilizing heat to stimulate glycerol and fatty acid evaporation, with glycerine evaporating more readily due to its lower boiling point.
Evaporation
Thorough refinement of glycerine involves the removal of residual methanol from the deacidification process. Evaporating the methanol guarantees the production of meticulously refined glycerine.
