Vegetable glycerine is primarily obtained during the soap-making process called saponification. It starts with plant-based oils like coconut, palm, or soybean being extracted and then treated with an alkali like sodium hydroxide.
Glycerine production process
- Oil or Fat Extraction: Plant-based oils or fats are extracted from the source material, such as coconuts, using processes like pressing or solvent extraction.
- Saponification: The extracted oils or fats are then subjected to a process called saponification, which involves treating them with an alkali such as sodium hydroxide (lye). This reaction breaks down the triglycerides into glycerol and fatty acids.
- Distillation and Purification: The glycerol is separated from the fatty acids through distillation or other separation methods. It is then further purified to remove impurities and residual chemicals.
- Neutralization: The purified glycerol is often treated to neutralize any remaining traces of alkali from the saponification process.
- Further Refinement: Depending on its intended use, the glycerol may undergo additional refining steps to meet specific purity and quality standards.
