Refined Glycerine 99.7% Min USP (Thailand Origin)

Brief Overview
Refined glycerine, also recognized as glycerol or glycerin, is a simple sugar alcohol featuring three hydroxyl groups, contributing to its hygroscopic and water-soluble qualities. Manifesting as a colorless, scentless, and crystal-clear liquid with a high boiling point and viscosity, this substance highlights its inherent sweetness and minimal toxicity. Its boiling point is 290°C, while its normal melting point is 17.8°C. The density of refined glycerine is 1.26 g/cm³. Originating from petrochemical feedstock, it serves diverse sectors, including biodiesel production, food, medicine, cosmetics, and personal care.
Manufacturing Process
Threshing
The initial phase in palm fruit treatment involves the removal of the primary stem and associated spikelets.
Sterilization
Steaming palm fruits aids in inhibiting oxidation and hydrolysis, facilitating the separation of resin, gum, and kernel.
Digestion
Mechanically mixing and pounding sterilized fruits, coupled with additional heat, promotes the release of palm oil.
Pressing
Hydraulic pressure extraction is employed to extract oil from processed fruit.
Oil Clarification
The oil undergoes heating to eliminate impurities, followed by filtration.
Deacidification
Solvent extraction with methanol removes free fatty acids crucial for preventing oil oxidation.
Transeferication/Saponification
Hydrolyzing triglycerides yields glycerol and fatty acids; refined glycerine is obtained through further refinement.
Glycerin Pretreatment
Distillation is one method employed to purify the combination of glycerine and fatty acids.
Evaporation
The comprehensive purification of glycerine involves evaporating residual methanol from the deacidification process.
