Overview
ISO 3761:2005 defines quality characteristics and test requirements for oil of rosewood, Brazilian type (Aniba rosaeodora Ducke or Aniba parviflora (Meisn.) Mez.). The standard specifies sensory and physical properties, chemical limits and a normative chromatographic profile to facilitate reliable assessment of this essential oil’s quality for fragrance, flavor and raw-material uses.
Key topics and requirements
- Scope: Applies to essential oil obtained by steam distillation of wood from Aniba rosaeodora or Aniba parviflora.
- Appearance, colour and odour:
- Clear, mobile liquid; colourless to pale yellow.
- Odour: characteristic, sweet, recalling linalool.
- Physical constants:
- Relative density at 20 °C (d20): 0.870 – 0.887.
- Refractive index at 20 °C (n20): 1.4620 – 1.4690.
- Optical rotation at 20 °C: −2.50° to +4.00°.
- Chemical limits:
- Acid value: max 1.
- Ester value: max 5.
- Ester value after acetylation: min 247 (≈82% linalool alcohol content) to max 280 (≈96%).
- Chromatographic profile (normative):
- Analysis by gas chromatography required; specific components and proportions must match the profile (e.g., linalool 70–90%, α-terpineol 2–7%, geraniol 0.5–2.5%; other constituents present as traces or small percentages).
- Chromatographic profile is normative - compliance is mandatory for quality assessment.
- Miscibility and flashpoint:
- Miscibility in 60% ethanol: a clear solution obtainable using no more than 9 volumes ethanol per 1 volume oil.
- Informative mean flashpoint: +67 °C (Setaflash).
- Sampling & test volume:
- Minimum test sample: 25 ml.
- Referenced test methods:
Practical applications
- Ensures consistent quality control for rosewood oil used in perfumery, aromatherapy, flavoring and raw-material procurement.
- Enables laboratories and suppliers to verify authenticity and composition using standardized gas chromatography and physicochemical tests.
- Supports regulatory compliance, material specifications and purchasing contracts where a reproducible chemical profile is required.
Who should use this standard
- Essential oil producers and distillers
- Quality control and analytical chemistry laboratories
- Perfumers, flavor houses and ingredient buyers
- Standards bodies and regulatory authorities managing botanically derived oils
