How to (truly) choose an aromatherapy product for my cosmetic formulation?

Formulating with natural botanical extracts means navigating between 4 requirements that do not always align: formula stability, batch traceability, content of active molecules, and regulatory compliance (organic, COSMOS, IFRA).

Essential oils gain their reputation for stability and biochemical strength. Hydrolats should be prioritized if you are working with the aqueous phase or a leave-on product.

Whether you’re a laboratory or a cosmetic brand, you know it: how to trust aromatherapy in the face of these dilemmas?

This guide provides the perspective of a producer-distiller with expertise deeply rooted in the reality of upstream production.

How to formulate essential oils or hydrosols while ensuring regulatory compliance?

All formulations must now refer to the 51st amendment of the IFRA standards (notified in June 2023). This text imposes strict limits based on aggregated exposure to avoid sensitization.

Essential oils are a major source of declarable allergens: linalool (Lavandula angustifolia), geraniol (Rosa damascena), citral (citrus), isoeugenol (Cananga odorata).

The Problem: Identifying components to declare by batch

The biochemical composition of an essential oil varies from one batch to another depending on the season, soil, and distillation date. A supplier who does not provide GC/MS chromatography by batch leaves you working with generic data, incompatible with precise IFRA calculations and reliable allergen declarations in your safety data sheet.

The Response from Domaines des Arômes Français: An analysis report

For each batch, we provide complete GC/MS chromatography: detailed composition by percentage per molecule, batch number, distillation date, origin of the plot.

How to order in bulk (MOQ, formats, timelines)?

We cater to professionals: cosmetic laboratories, clean beauty brands, independent formulators, soap makers, and training organizations.

The problem: high MOQs and incomplete documentation from traditional suppliers

Many cosmetic subcontractors impose minimum orders that are too large, incompatible with a R&D phase or a small batch. Certificates are generic, not linked to the delivered batch, or insufficient for a COSMOS audit or EU market launch.

The response from Domaine des Arômes Français: from 1 kg, with all documentation

MOQ: from 1 kg on our e-commerce — turnkey order, with no long-term commitment for initial orders. For custom needs (specific chemotype, non-catalog format, non-standard volume), we work on a quote basis.

Available formats: amber glass bottles of 1 L for essential oils, 5 L / 25 L drums for professional bulk, 1 L glass bottles for hydrosols. Packaging available upon request. This includes light-protective glass or stainless steel.

Timelines: For the e-commerce format, shipping within 2 to 5 business days (France). Seasonal products (Helichrysum, Damask Rose, Immortelle): pre-order recommended.
