Technical Document


Refined glycerine, also known as glycerol or glycerin, is a basic sugar alcohol with three hydroxyl groups, playing a role in its water solubility and hygroscopic characteristics. This substance, characterized by a colorless, odorless, and transparent liquid, emphasizes its intrinsic sweetness and minimal toxicity. Additionally, it possesses a high boiling point and viscosity. Originating from petrochemical feedstock, it is utilized across diverse industries such as food, medicine, cosmetics, personal care, and biodiesel production.



Palm fruit harvested from the fields undergoes meticulous threshing to eliminate the main stem and attached spikelets.


Utilizing steam, the palm fruit undergoes a sterilization process to prevent hydrolysis and oxidation. The applied heat expands internal moisture, facilitating the separation of kernel, gum, and resin.



Mechanically mixed and pounded in a rotating shift under elevated temperatures, sterilized palm fruits release palm oil. Additional heat aids the process, taking advantage of the oil's low viscosity.


Hydraulic pressure extraction in a metal cage is employed to press processed palm fruit, extracting palm oil.

Oil clarification

Purification of extracted palm oil involves the addition of hot water to remove impurities, followed by filtration. The separated water and oil layers are decanted for subsequent processing.


 Free fatty acids are removed from palm oil through solvent extraction with methanol, a crucial step in preventing oxidation and undesirable odors.


Hydrolysis breaks down deacidified palm oil into glycerol/glycerine and fatty acid chains. Further refinement is imperative for the glycerine to attain the label of refined glycerine.

Glycerin pre-treatment

 Refinement of the mixture of glycerine and fatty acid chains occurs through distillation. Heating the distillation column encourages glycerol and fatty acid evaporation, with glycerine exhibiting a more rapid evaporation due to its lower boiling point.


Complete purification of glycerine involves the evaporation of residual methanol from the deacidification process, resulting in fully refined glycerine.


Pharmaceuticals Industry
The pharmaceutical industry relies heavily on glycerine as a raw material for medications, suppositories, cough treatments, and anesthetics.

Cosmetic Industry
The moisture-keeping qualities of glycerine improve the shelf life of cosmetic goods while retaining their softness and creaminess.

Food Industry
Used as a sports hydration aid and as a sweetener in a variety of food items.

Industrial Applications
Research on glycerine as an additive for gasoline to lower hazardous emissions is still ongoing. Its lubricating qualities diffuse heat, lower friction, improve mechanical efficiency, and guard against overheating. Due to its economic viability, glycerine is used as a chemical intermediate and in a variety of industrial applications
