Technical Document


Refined glycerine, sometimes known as glycerol or glycerin, is a simple sugar alcohol with three hydroxyl groups, which help to make it water soluble and hygroscopic. This material has a high boiling point and viscosity, and it appears as a colorless, odorless, and transparent liquid that emphasizes its natural sweetness and low 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. It comes from petrochemical feedstock and is used in food, medicine, cosmetics, personal care, and biodiesel manufacturing, among other industries.



Thorough threshing marks the initial stage in palm fruit treatment, eliminating the primary stem and any attached spikelets.


Steaming palm fruits prevents hydrolysis and oxidation, facilitating the separation of resin, gum, and kernel.


Mechanically mixing and pounding sterilized fruits releases palm oil, aided by additional heat.


Hydraulic pressure extraction is utilized to obtain oil from processed fruit

Oil Clarification

Following extraction, the oil undergoes purification through the addition of hot water to eliminate impurities, followed by filtration.


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


Further refinement is necessary to produce refined glycerine as hydrolysis breaks down triglycerides into glycerol and fatty acids.

Glycerin Pretreatment

Distillation serves as one of the separation techniques to purify the glycerine and fatty acid combination.


The complete purification of glycerine involves the evaporation of residual methanol from the deacidification process.

Pharmaceuticals Industry

Suppositories, cough cures, anesthetics, and other medications are made possible by glycerine, an essential raw component in the industry.
Cosmetic Industry

The moisturizing qualities of glycerine help cosmetics keep their smooth, creamy feel for longer periods of time on the shelf.

Food Industry

Used as a sports hydration aid and as a sweetener in a variety of dishes.

Industrial Applications

Research on glycerine as an addition to gasoline to lower harmful emissions is still ongoing. Its lubricating qualities reduce friction, disperse heat, stop overheating, and improve mechanical efficiency. Glycerine is a valuable chemical intermediate with a wide range of industrial uses due to its economic feasibility.
