Overview
ISO 21099:2026 specifies the quality characteristics for the essential oil of rockrose labdanum (Cistus ladanifer L.). Developed by ISO Technical Committee 54 on Essential Oils, this international standard aims to support the global essential oils industry by establishing a clear, consistent basis for the assessment of rockrose labdanum oil quality. By referencing defined test methods and chromatographic profiles, ISO 21099:2026 enhances product consistency, safety, and traceability for manufacturers, suppliers, and end-users.
Key Topics
-
Quality Criteria: ISO 21099:2026 defines specific physical and chemical properties of essential oil of rockrose labdanum, including:
- Appearance: Clear mobile liquid
- Colour: Ranging from pale yellow to intense yellow, even orange
- Odour: Woody, amber-like, balsamic, spicy
- Relative density at 20°C
- Refractive index at 20°C
- Optical rotation at 20°C
-
Chromatographic Profile: The standard establishes a normative gas chromatographic fingerprint-detailing the minimum and maximum percentage of key components (such as α-pinene, camphene, p-cymene, borneol, and viridiflorol)-to facilitate quality verification.
-
Sampling Requirements: Guidance is provided for the correct collection of representative samples, ensuring reliability and repeatability in tests.
-
Packaging, Labelling, and Storage: ISO 21099:2026 references general ISO standards for proper packaging, marking, labelling, and storage conditions, ensuring preserved quality during handling and shipment.
-
Test Methods: The document refers to ISO methods for determination of key physical properties and chromatographic analysis, ensuring consistency and comparability of results across different laboratories.
Applications
ISO 21099:2026 serves multiple sectors within the essential oils industry and is relevant to:
- Producers and Processors: Assisting in quality management and production control by providing explicit oil specifications and test methods.
- Suppliers and Exporters: Documenting compliance with internationally recognized standards, facilitating market access and regulatory approvals.
