Technical Document

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


The initial phase in palm fruit treatment involves the removal of the primary stem and associated spikelets.


Steaming palm fruits aids in inhibiting oxidation and hydrolysis, facilitating the separation of resin, gum, and kernel.


Mechanically mixing and pounding sterilized fruits, coupled with additional heat, promotes the release of palm oil.


Hydraulic pressure extraction is employed to extract oil from processed fruit.

Oil Clarification

The oil undergoes heating to eliminate impurities, followed by filtration.


Solvent extraction with methanol removes free fatty acids crucial for preventing oil oxidation.


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.


The comprehensive purification of glycerine involves evaporating residual methanol from the deacidification process.

Pharmaceuticals Industry

Glycerine, a vital raw ingredient in the pharmaceutical sector, contributes to suppositories, cough remedies, anesthetics, and various pharmaceuticals.

Cosmetic Industry

Glycerine's moisture-retaining properties extend the shelf life of cosmetics while preserving their smoothness and creamy texture.

Food Industry

Employed as a sweetener in various foods and as a hydration aid in sports.

Industrial Applications

Ongoing research explores glycerine as an additive for gasoline to reduce hazardous emissions. Its lubricating properties prevent overheating, distribute heat, lower friction, and enhance mechanical efficiency. Glycerine, valued for its economic viability, serves as a chemical intermediary and finds applications in diverse industrial sectors
