Saipol markets crude vegetable glycerine, a by-product of processing vegetable oils into biodiesel or Oleo100 energy. Saipol is one of Europe’s leading producers of crude vegetable glycerine due to its position as the French leader in biodiesel.
Crude glycerine is a viscous, dark yellow to brown liquid. The glycerine produced by Saipol has a concentration of 80% or 90% of glycerol and is intended for technical use, for use in animal feed, or to be refined before being used in human food or cosmetics.
In its raw form, vegetable glycerine has similar properties to refined glycerine: it can be used as emollient, thickening, lubricating agent, etc.

Focus on the production of crude vegetable glycerine
Vegetable glycerine is a by-product of the reaction between a vegetable oil (triglyceride) and an alcohol (methanol) to produce a vegetable oil methyl ester (biodiesel). The reaction occurs naturally by mixing oil and alcohol and is accelerated by a catalyst.
Production can be made by batch or continuously depending on the industrial process.
The esters and glycerine are then separated by simple decantation (glycerine is lighter than the ester) and by distillation.
