Natural essential oils remain in demand across the European cosmetics and fragrance industries. However, manufacturers of finished products increasingly need more than information about origin and aroma — they also require detailed data on chemical composition.

One of the reasons is the updated European requirements for the labelling of fragrance allergens in cosmetic products.
A New Stage of Requirements Is Already in Effect
The European Union has expanded its requirements for the individual labelling of fragrance allergens in cosmetics.
The first transition period ended on 31 July 2026. This means that new cosmetic products placed on the EU market for the first time after this date must comply with the updated requirements of Regulation (EU) 2023/1545.
For cosmetic products that had already been placed on the market before 31 July 2026, an additional transition period applies until 31 July 2028.
The updated rules expand the list of fragrance substances that must be individually declared in the ingredient list when they exceed established concentration thresholds.
How This Relates to Essential Oils
An essential oil is a complex natural mixture that may contain dozens of volatile compounds, including substances subject to specific labelling requirements under European legislation.
The concentration of individual components may vary depending on the plant variety, growing region, climate, harvest stage, and production method.
For cosmetics manufacturers, it is therefore important to know not only the name of the essential oil, but also the actual composition of each specific batch.
What Matters to European Buyers
When selecting essential oils, European companies increasingly request detailed technical documentation.
For B2B supply, particularly important information includes:
- the exact botanical name of the plant;
- the part of the plant used;
- the production method;
- product specification;
- chromatographic profile;
- information on composition and relevant fragrance allergens;
- Safety Data Sheet and other documentation depending on the intended application.
This information helps manufacturers assess the raw material more accurately during product development.
Natural Origin and Quality Control
Natural origin does not mean that the composition of an ingredient is completely fixed.
It is precisely this natural variability that makes batch control so important. For the professional market, a high-quality essential oil is not only defined by its characteristic aroma, but also by clear origin, measurable specifications, and appropriate documentation.
Conclusion
Changes in European legislation reinforce a broader industry trend: cosmetics manufacturers need increasingly detailed information about natural aromatic raw materials.
For essential oil suppliers, this means that analytical control, batch consistency, and transparent technical documentation are becoming even more important.
