Refined Glycerine 99.5% Min USP BP

Brief Overview
Refined Glycerine, alternatively known as glycerol or glycerin, emerges as a foundational sugar alcohol featuring three hydroxyl groups, imparting water solubility and hygroscopic attributes. This crystal-clear, colorless, and fragrance-free liquid, distinguished by a high boiling point and viscosity, unveils inherent sweetness and minimal toxicity. Boasting a density of 1.26 g/cm³, it originates from petrochemical feedstock and caters to an array of sectors, including food, medicine, cosmetics, personal care, and biodiesel production.
Manufacturing Process
Threshing
The initial treatment of palm fruit involves meticulous threshing to eliminate the primary stem and attached spikelets.
Sterilization
The application of steam to palm fruits prevents hydrolysis and oxidation, facilitating the detachment of kernel, gum, and resin.
Digestion
Mechanically mixing and pounding sterilized fruits release palm oil, aided by additional heat.
Pressing
Hydraulic pressure extraction is employed to obtain palm oil from processed fruits.
Oil Clarification
The extracted oil undergoes purification, involving the addition of hot water for impurity removal and subsequent filtration.
Deacidification
Solvent extraction with methanol eliminates free fatty acids, crucial for preventing oil oxidation.
Transeferication/Saponification
Hydrolysis breaking down triglycerides into glycerol and fatty acids necessitates further refining for refined glycerine.
Glycerin Pre-treatment
Separation processes refine the mixture of glycerine and fatty acids through distillation.
Evaporation
Remaining methanol from the deacidification process is evaporated to produce fully refined glycerine.
