Refined Glycerine 99.7% Min Vegetable (Argentina Origin)

Brief Overview

Refined glycerine, also known as glycerol or glycerin, is a basic sugar alcohol with three hydroxyl groups that give it its water solubility and hygroscopic qualities. This substance's colorless, odorless, and transparent liquid condition draw attention to its natural sweetness and minimal toxicity. Both its boiling temperature and viscosity are high. It is derived from petrochemical feedstock and finds application in a range of industries, such as biodiesel, food, pharmaceutical, cosmetic, and personal care.

Manufacturing Process

Threshing

The first step in processing palm fruit involves carefully removing the main stem and attached spikelets.

Sterilization

The palm fruit undergoes steam sterilization at high temperatures to prevent oil oxidation and hydrolysis, aiding in separating the fruit's walls from the kernel, gum, and resin due to enhanced internal moisture.

Digestion

Sterilized palm fruits are mechanically mixed and smashed at elevated temperatures, breaking down the pulp and cells to release palm oil with added heat for smooth mixing.

Pressing

Processed palm fruit undergoes pressing in a hydraulic machine to extract palm oil, collected for further processing.

Oil clarification

After extraction, the oil undergoes purification with hot water, initiating a separation process and filtering particles to create a clear distinction between water and oil layers.

Deacidification

Solvent extraction with methanol is used to remove free fatty acids, enhancing the oil's shelf life and preventing oxidation and unwanted odors.

Transeferication/Saponification

Hydrolysis under high pressure and temperature breaks down deacidified palm oil into fatty acid and glycerol/glycerine chains. While glycerine is now ready for extraction, further refinement is needed before labeling it as refined glycerine.

Glycerin pre-treatment

Various separation techniques are applied to purify the combination of glycerine and fatty acid chains. Distillation extracts glycerine, utilizing heat to encourage glycerol and fatty acid evaporation, with glycerine evaporating more readily due to its lower boiling point.

Evaporation

Complete refinement of glycerine involves eliminating residual methanol from the deacidification process. Evaporating the methanol ensures the production of thoroughly refined glycerine

Pharmaceuticals Industry

The pharmaceutical industry relies greatly on glycerine as a raw substance for medications, suppositories, cough treatments, and anesthetics.

Cosmetic Industry

Glycerine's ability to hold moisture extends the shelf life of cosmetics while preserving their smoothness and creaminess.

Food Industry

Added to a range of food products as a sweetener and as a sports hydration aid.

Industrial Applications

Research is still being done on the use of glycerine as an addition to gasoline to reduce harmful emissions. Its lubricating properties prevent overheating, reduce friction, disperse heat, and increase mechanical efficiency. Glycerine is employed as a chemical intermediate and in many different industrial applications because of its economic feasibility.
