Essential oil isolates
Essential oil isolates are entirely natural products, as they are free from chemical reactions. They are obtained from essential oils placed in large-capacity distillation columns. The constituent(s) thus separated then undergo several operations to produce pure isolates.
Our SGP3 site notably includes three Sulzer distillation columns, with boilers with a capacity of 3000 liters. These columns stand out for their diameter and the height of their BX type packing: 14 meters, a technological achievement in the field of essential oil fractionation. To preserve production from thermal degradation, distillation is performed at a reduced temperature, in an environment maintained under partial vacuum by falling film exchanger.
Essentail oil derivates
An essential oil isolate can be modified by adding hydrogen atoms, carbon atoms, etc. This process is called hemisynthesis.
The essential oil derivative obtained using this process is characterized by properties different from those of the isolate used, in terms of smell or aroma. We have traditional stainless steel reactors, as well as vitrified De Dietrich reactors for acidic reactions. Our vacuum fractionation columns also contribute to the production of the highest quality essential oil derivatives.
Before being used as a raw material, a molecule may require improvement, whether for purification, decolorization, or deodorization. The technique consists of molecular distillation. It requires perfect mastery of devices using cutting-edge technology.
Molecular distillation is one of the skills of Société Grassoise de Parfumerie : we have two UIC molecular distillation devices, one for productions in small quantities, the other for industrial quantity productions.
