Full title and description

STB BS ISO 4716-2013 — Essential oil of vetiver [Chrysopogon zizanioides (L.) Roberty, syn. Vetiveria zizanioides (L.) Nash]. This adoption corresponds to ISO 4716:2013 and defines origin‑dependent characteristics and analytical requirements used to assess the quality and authenticity of vetiver essential oil.

Abstract

ISO 4716:2013 specifies physicochemical and chromatographic characteristics for vetiver essential oil produced in Reunion Island, China, Haiti, Indonesia, Madagascar, Brazil and Comoros to facilitate consistent quality assessment and trade. The standard sets appearance, odour descriptors, quantitative test limits (density, refractive index, optical rotation, acid value, miscibility) and a chromatographic profile with marker compound ranges to support routine quality control.

Scope

This standard applies to essential oil of vetiver (Chrysopogon zizanioides, syn. Vetiveria zizanioides) produced in specified origins (Reunion Island, China, Haiti, Indonesia, Madagascar, Brazil and Comoros). It defines physical and organoleptic descriptors, origin‑dependent numerical limits for key physicochemical parameters and a chromatographic (GC) fingerprint and marker compound ranges to enable identification, quality assessment and trade acceptance.

Key topics and requirements

• Defined origins and “Bourbon type” classification (Reunion, Comoros, Madagascar) with origin‑specific parameter ranges.
• Physical and organoleptic description: appearance (viscous liquid), colour (yellowish‑brown to reddish‑brown), characteristic woody/earthy odour.
• Mandatory physicochemical tests at 20 °C: relative density (d20), refractive index (n20), optical rotation (10% solution), miscibility in 80% ethanol, acid value; origin‑dependent limits are given.
• Chromatographic profile (GC): normative marker compounds and proportion ranges (e.g. β‑vetivenene, β‑vetivone, khusimol, α‑vetivone, isovalencenol); recommended dilution and column types due to viscosity.
• Sampling and test method references: sampling per ISO 212 and normative cross‑references to ISO test methods for density, refractive index, optical rotation, miscibility and acid value.
• Supplementary information on safety/transport (flashpoint) and guidance for handling and labelling (annex material referenced).

Typical use and users

Used by quality control laboratories in the fragrance, cosmetics, aromatherapy and flavour industries; by producers and distillers for product specification and origin characterization; by buyers, traders and certification bodies for acceptance testing and commercial quality control; and by analytical chemists implementing GC fingerprinting and physico‑chemical assays. Regulatory, transport and insurance stakeholders also reference the standard for safe handling/label information.

Related standards

Normative and informative cross‑references include ISO/TR 210 and ISO/TR 211 (essential oils guidance), ISO 212 (sampling), ISO 279 (density), ISO 280 (refractive index), ISO 592 (optical rotation), ISO 875 (miscibility), ISO 1242 (acid value) and ISO 11024 (gas chromatographic profiling of essential oils). These standards support sampling, analytical methods and chromatographic practice referenced in ISO 4716:2013.

FAQ

Q: What is this standard?

A: ISO 4716:2013 (adopted as STB BS ISO 4716-2013 in national catalogues) is an international standard defining required characteristics and analytical criteria for vetiver essential oil to support consistent quality assessment and trade.

Q: What does it cover?

A: It covers origin scope, physical and organoleptic descriptors, origin‑dependent numeric limits for key physicochemical parameters, a GC chromatographic fingerprint with marker compound ranges, sampling instructions and references to standard test methods.

Q: Who typically uses it?

A: Producers/distillers, quality control and analytical laboratories in fragrance/cosmetics/aroma industries, buyers and traders, certification bodies and regulatory or transport stakeholders concerned with safe handling and accurate product description.

Q: Is it current or superseded?

A: The 2013 edition (ISO 4716:2013) replaced the 2002 edition (ISO 4716:2002). As published in 2013 it is the current ISO edition for vetiver oil; users should check their national adoption records (STB/BS or other prefixes) for any later national amendments or confirmations.

Q: Is it part of a series?

A: It is one of a family of ISO standards and technical reports managed under ISO/TC 54 (Essential oils). It cross‑references other ISO methods and guidance documents that together form the test and sampling framework for essential oils.

Q: What are the key keywords?

A: Vetiver, vetiver oil, Chrysopogon zizanioides, essential oil, chromatographic profile, density, refractive index, acid value, GC fingerprint.
