Earthy -
The provocative odor of freshly turned earth, musty and rooty.

Enfleurage -
In this process, aroma materials are absorbed into wax and then the odorous oil is extracted with ethyl alcohol. Extraction by enfleurage was commonly used when distillation was not possible because some fragrant compounds denature through high heat. This technique is not commonly used in the present day industry due to its prohibitive cost and the existence of more efficient and effective extraction methods.

Environmental Fragrancing -
The use of a pleasant scent to enhance the comfort, enjoyment and overall perception of indoor spaces.

Essences -
Products which endeavor to capture or emphasize the highly volatile top notes of natural products.

Essential -
Volatile oil obtained by various processes from flowers, leaves, roots, barks, stems, fruits, seeds and woods.

Essential Oil -
The “essence” of plants obtained by distillation of the plant material or its concrete. Plant materials include flowers, grass, stems, seeds, leaves, roots, bark, fruits, tree moss and tree secretions.

Evanescent -
Fleeting or quickly vanishing fragrance.

Evaporation -
The process of changing from a liquid to a vapor.

Expression -
Raw material is squeezed or compressed and the oils are collected. Of all raw materials, only the fragrant oils from the peels of fruits in the citrus family are extracted in this manner since the oil is present in large enough quantities as to make this extraction method economically feasible.

Extracts -
Concentrated perfume or flower products obtained through the process of extraction using volatile solvents.
