ESSENTIAL OIL ANALYSES

ESSENTIAL OIL ANALYSIS

The analysis of essential oils (EO) is crucial across various sectors, including perfumery, cosmetics, aromatherapy, and healthcare. The quality of essential oils is fundamentally linked to the verification of their chromatographic conformity with established standards, such as AFNOR standards and applicable pharmacopoeias in different countries. A comprehensive analysis of essential oils and their contaminants is an integral part of the regulatory requirements necessary for IFRA certification and compliance with cosmetic regulations.

In the field of aromatherapy, verifying the chemotype of an essential oil is particularly important. The chemotype reflects the specific chemical composition of the oil, which directly influences its therapeutic efficacy. By identifying the correct chemotype, practitioners can ensure they are using oils that deliver the desired effects while minimizing the risks associated with improper use.

At ScentXpertiseS, we bring over 20 years of expertise in this domain, enabling us to perform high-level analyses that adhere to the best practices in the industry. Our proficiency in methods such as gas chromatography with flame ionization detection (GC/FID) and gas chromatography-mass spectrometry (GC/MS) allows us to provide comprehensive and reliable assessments of essential oils.

The accuracy of our analyses not only ensures compliance with industry standards, but also supports our clients in making informed decisions regarding the use of essential oils in their products. Whether for therapeutic applications in aromatherapy or for fragrance development in perfumery and cosmetics, we deliver the critical information required for essential oil evaluation.

Basic Pack 1 –

GC/MS Identification

Package details:

• GC/MS analysis on a single column (polar or non-polar, your choice)

• Identification of the 10 to 15 major peaks according to pharmacopeia, AFNOR standards, or a predefined list

Deliverable:

Analysis report including the chromatogram, analytical conditions, and the compounds identified by GC/MS

Basic Pack 2 – Identification + % FID

Package details:

• Includes Basic Pack 1

• Addition of GC/FID analysis on a column of the same polarity as Basic Pack 1

• Determination of % FID and correlation with the 10–15 peaks identified by GC/MS

• Verification of compliance with standards, pharmacopeias, or other provided references

Deliverable:

Analysis report including the chromatogram, analytical conditions, GC/MS-identified compounds, associated % FID, compliance ranges, and overall conformity

Package details:

• Includes Basic Pack 1 or 2, your choice → limited to the 10–15 major peaks and markers on a single column (polar or non-polar, your choice)

• Additional engineer time for bibliographic research

Deliverable:
Analysis report including:

• Chromatogram and analytical conditions

• Compounds identified by GC/MS (if based on Basic Pack 1)

• Associated % FID (if based on Basic Pack 2)

• Relevant bibliographic references, including details such as % composition, occurrence, author, and links to the references

Intended for essential oils without official AFNOR, pharmacopeia, reference standards, or comparison bibliography

Basic Pack 3 – Essential Oils without Official Reference

Intermediate Pack – Analysis with Linear Retention Index (LRI)

Package details:

• Includes Basic Pack 1, 2, or 3

• Addition of LRI values to confirm compound identities, following professional best practices for identification, by comparing the analysis values with literature data or ScentXpertiseS LRI databases

Deliverable:

Same as Basic Pack 1, 2, or 3, plus an additional column in the results table showing the LRI for each identified peak in the mixture and its reference value from the literature

QUANTIFICATION PACK - REAL MASSIC DOSAGE

Package details:

• Includes Basic Pack 2 or 3

• Quantification of compounds in weight/weight (% w/w) via GC/FID using internal calibration and predicted response factors (RRF) according to the combustion enthalpy method, officially recommended by IOFI

Deliverable:

Same as Basic Pack 2 or 3, with an additional column in the results table showing the % mass of the identified compounds

Package details:

• Includes the LRI option

• Includes bibliography

• Identification (GC/MS + LRI) of all detectable peaks on a column (polar or non-polar, your choice)

• Search for expected compounds based on literature

• Specification of m/z fragments for unknown compounds >1%

• Determination of % FID and correlation with GC/MS-identified or unknown peaks >1%

• Comparison with bibliographic data

Deliverable:

Same as Basic Pack 3, plus LRI option for all identified and unknown compounds >1%
