This document gives a list of the botanical names of plants used for the production of essential oils, in order to harmonize their nomenclature.
In addition to this document, ISO/TC 54, Essential oils, has established ISO/TR 210928, in which different numbers (CAS-USA, EINECS, CAS-EINECS, Fema, EC and FDA numbers) are listed for the characterization of essential oils.
Characterization of essential oils by using a single number (e. g. CAS number) would not be complete and it could lead to ambiguity and misunderstandings.
That is the reason why, through ISO/TR 21092, ISO/TC 54 intends to provide the users of essential oils with useful information for a complete characterization of essential oils included in this document.
