Overview

ISO 3757:2002 is an international standard published by the International Organization for Standardization (ISO) that defines the quality characteristics of oil of patchouli, derived from Pogostemon cablin (Blanco) Benth., a plant of the Lamiaceae family. This essential oil is widely used in perfumery, cosmetics, and aromatherapy due to its distinctive aromatic profile and therapeutic properties. The standard establishes consistent criteria for assessing the quality, purity, and composition of patchouli oil, helping producers, suppliers, and buyers ensure product authenticity and reliability across the global market.

Key Topics

  • Scope and Definition
    ISO 3757 specifies the properties required to evaluate patchouli oil quality, focusing on physical characteristics like appearance, color, and odor. It also sets parameters for chemical attributes and chromatographic profiles for detailed analysis.

  • Physical Properties

    • Appearance: Liquid with variable viscosity
    • Color: Yellow to reddish brown
    • Odor: Leafy, humic, clinging
    • Relative density at 20 °C: 0.952 to 0.975
    • Refractive index at 20 °C: 1.5050 to 1.5150
    • Optical rotation at 20 °C: −60° to −40°
    • Miscibility: Must be soluble in 90% ethanol under defined conditions
  • Chemical Properties

    • Acid value: Maximum 4
    • Ester value: Maximum 10
  • Chromatographic Profile
    Gas chromatography analysis is mandatory to identify key components such as β-patchoulene, α-guaiene, β-caryophyllene, bulnesene, patchoulol, and pogostol, among others. The standard specifies quantitative ranges for these constituents, ensuring the chemical fingerprint of authentic patchouli oil.

  • Sampling and Testing
    Minimum test sample volume is 25 ml to ensure all tests can be accurately conducted, with test methods referenced from related ISO standards addressing density, refractive index, optical rotation, miscibility, acid and ester values, and chromatographic profiling.

  • Packaging and Labeling
    Packaging, conditioning, and labeling requirements follow related ISO guidelines, enhancing traceability and safe handling.

  • Flashpoint
    An informative annex provides a typical flashpoint value of +116 °C, relevant for transportation and safety regulation compliance.

Applications

  • Quality Control and Assurance
    ISO 3757 facilitates the consistent evaluation of patchouli oil batches, critical for producers and manufacturers in perfumery, cosmetics, and aromatherapy industries to maintain high-quality standards.

  • Trade and Regulatory Compliance
    Traders and regulatory bodies use the standard as a reference to verify the authenticity and purity of patchouli oil, preventing adulteration and assuring compliance with international trade regulations.

  • Research and Development
    Laboratories conducting chemical analysis can apply the chromatographic profile data specified to characterize samples and develop new products or formulations based on patchouli oil.

  • Safety Management
    Information on physical and chemical properties assists in safe handling, storage, and transportation, reducing risks associated with flammable essential oils.

Related Standards

  • ISO 11024-1 & ISO 11024-2 – Guidance on preparation and utilization of chromatographic profiles for essential oils
  • ISO/TR 210, 211, 212 – General rules for packaging, labeling, and sampling of essential oils
  • ISO 279, 280, 592, 709, 875, 1242 – Standardized test methods for determination of essential oil physical and chemical parameters such as density, refractive index, optical rotation, ester value, and acid value
  • ISO/TR 11018 – Methods for determining flashpoint of essential oils
  • ISO/TR 21092 – Essential oils characterization through CAS number and other identifiers

Adherence to ISO 3757:2002 strengthens trust in patchouli oil quality worldwide, supporting fair trade and consistent product performance for industrial users and consumers alike. This standard is an essential reference for anyone involved in the production, analysis, sale, or usage of patchouli essential oil.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
The main task of technical committees is to prepare International Standards. Draft International Standards adopted
by the technical committees are circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 3757 was prepared by Technical Committee ISO/TC 54, Essential oils.
This second edition cancels and replaces the first edition (ISO 3757:1978), which has been technically revised.
Annexes A and B of this International Standard are for information only.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée aux
comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du comité
technique créé à cet effet. Les organisations internationales, gouvernementales et non gouvernementales, en
liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec la Commission
électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 3.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur publication
comme Normes internationales requiert l'approbation de 75 % au moins des comités membres votants.
L'attention est appelée sur le fait que certains des éléments de la présente Norme internationale peuvent faire
l'objet de droits de propriété intellectuelle ou de droits analogues. L'ISO ne saurait être tenue responsable de ne
pas avoir identifié de tels droits de propriété et averti de leur existence.
L'ISO 3757 a été élaborée par le comité technique ISO/TC 54, Huiles essentielles.
Cette deuxième édition annule et remplace la première édition (ISO 3757:1978), dont elle constitue une révision
technique.
Les annexes A et B de la présente Norme internationale sont données uniquement à titre d’information.
