«Ethereal oil» or «essence»?

Scientific substantiation of term selection

Abstract

The substances which condition the plants odour and which are referred to as «ethereal oils» are polycomponent blends of natural aliphatic compounds of cyclohexane and cyclopentane range and do not have anything to do with oils (triacylglycerines). In order to designate such substances it is proposed to use the term «essences» that is spread in the Ukrainian language and is used in most European languages.
