Essential oils can be further refined according to different requirements


Essential oils can be further refined into terpenoid free essential oils, refined essential oils, concentrated essential oils, formulated essential oils, and recombinant essential oils according to different requirements.

Essential oils can be further refined into terpenoid free essential oils, refined essential oils, concentrated essential oils, formulated essential oils, and recombinant essential oils according to different requirements.
Terpeneless Oil 
Using vacuum distillation, selective solvent extraction, or a combination of distillation and extraction methods to partially or completely remove monoterpenes or sesquiterpenes contained in essential oils.
refined oil 
Essential oils processed by distillation or vacuum distillation are used to remove certain components that are unsafe to the human body, have unpleasant odors, or contain pigments, in order to improve their quality.
Concentrated essential oil
In order to meet the requirements of flavor and intensity of some essence, vacuum fractionation, or quenching, or preparative chromatography and other methods are used to remove the components without flavor value from the essential oil.
Prepare essential oils
In order to reduce costs or make up for the shortage of natural products, artificial blending methods are used to produce essential oils that approximate the aroma and other quality requirements of the natural product.
Recombinant essential oil
The use of certain methods to remove harmful ingredients and make the aroma and other quality requirements similar to natural products is called recombinant essential oil.
Plant essential oils can be divided into two categories based on their composition: single essential oils and compound essential oils. Unilateral essential oil is a simple essential oil extracted from plants without any additives, usually named after the extracted plant. Compound essential oil is a mixture of two or more plant essential oils, and the coordination between essential oils can enhance therapeutic effects.
