Overview
ISO/TS 24106:2021 - Essential oils: Name harmonization of components is a technical specification from ISO/TC 54 that standardizes the names of chemical components used across ISO standards in the field of essential oils. The document establishes a harmonized list mapping English and French component names and provides the corresponding CAS Registry Numbers (CAS RN®) for each entry. The specification is intended to ensure consistent chemical nomenclature and clear cross‑language identification in essential oil standards, test reports, specifications and regulatory paperwork.
Key Topics
- Name harmonization: A curated list of component names to be used in essential oil standards, specifying preferred common names (over IUPAC where customary).
- Bilingual correspondence: Clear mapping between English names and French names for all listed compounds to support international use.
- CAS Registry Numbers: Inclusion of CAS RN® for each component to enable unambiguous chemical identification in analytical and regulatory contexts.
- Isomer specificity: Where relevant, the specification distinguishes geometric or stereoisomers (e.g., (E)/(Z), α/β) to avoid ambiguity in reporting and testing.
- Scope and applicability: Applicable to all standards in the field “Essential oils”, intended for harmonization rather than imposing analytical methods.
- Usage note: CAS numbers are provided for convenience and do not constitute an ISO endorsement; equivalent identifiers or products may be used if they lead to the same results.
Applications
ISO/TS 24106:2021 is practical for professionals and organizations working with essential oils, including:
- Standards developers and standards committees who need a consistent source of component names for new or revised ISO standards.
- Analytical laboratories (GC‑MS, GC‑FID) preparing reports, chromatographic libraries and certificates of analysis that require precise chemical names and CAS identifiers.
- Quality control and R&D teams in the fragrance, flavor and aromatherapy industries that document composition, specifications and batch records.
- Regulatory affairs and compliance specialists preparing dossiers, safety data sheets (SDS) and labeling where multilingual, unambiguous chemical identification is required.
- Suppliers and procurement teams standardizing product descriptions, contracts and trade documentation to reduce confusion in international trade.
Related Standards
- Prepared by ISO/TC 54 (Essential oils); intended for use alongside other ISO essential oil standards (method standards, specifications and terminology) to maintain consistent nomenclature across the sector.
