Short answer
Selling fragrance oils to candle, soap and cosmetic makers turns a perfumer into a chemical supplier, with a supplier's duties. Each oil needs a safety data sheet and a hazard label wherever it is classified as hazardous, an IFRA certificate stating the maximum use level by product category, an allergen statement so customers can label their products, and often flash point, vanillin content and a specification. In the US the SDS follows OSHA's Hazard Communication Standard, in the EU and Great Britain REACH and CLP; an imported oil may need TSCA certification. Prepare the documents before the first sale, version them with the formula, and update them when the formula or the rules change.
Who your customers are, and what they ask for
| Document | What it tells the customer | Who mainly needs it |
|---|---|---|
| Safety data sheet (SDS) | Hazards, safe handling, transport, composition of hazardous components | Everyone; a legal duty for hazardous mixtures supplied to workplaces |
| IFRA certificate of conformity | Maximum use level of the oil in each IFRA category, and the Amendment it conforms to | Cosmetic, soap, candle and diffuser makers |
| Allergen statement | The declarable allergens in the oil and their percentages | Cosmetic and detergent makers, for their labels |
| Flash point | Flammability, for transport and candle making | Candle makers, shippers |
| Vanillin content, discoloration notes | Whether the oil will brown a soap or candle | Soap and candle makers |
| Specification or certificate of analysis | Appearance, density, refractive index; lot results | Larger customers, contract manufacturers |
| Compliance statements | TSCA, REACH, vegan, CMR-free, Prop 65 and similar, as requested | Importers, retailers, brands making claims |
The documents a buyer receives are described from the other side in fragrance material SDS and specifications and IFRA certificates.
Safety data sheets and labels
- US. OSHA's Hazard Communication Standard requires manufacturers and importers to classify hazardous chemicals and provide an SDS in the 16-section format, and to label containers, for chemicals supplied to employers. Most fragrance oils contain classified components — skin sensitizers, flammables, aquatic hazards — so most need one.
- EU and GB. CLP classification and labeling of the mixture, an SDS under REACH, and REACH registration duties for the substances depending on volumes and who imports them (REACH and CLP for fragrance oils).
- Consumer sale. Oils sold to the public — to hobbyists, in small bottles — also need the consumer labeling of the market, which may include child-resistant closures and tactile warnings (labeling candles, diffusers and room sprays covers the rules that are triggered).
Classifying a mixture is technical work. Many small suppliers use classification software or a consultant; whoever does it needs the full composition and each material's classification.
IFRA certificates
A certificate of conformity states, for one fragrance mixture, the maximum concentration at which it can be used in each IFRA category, and the Amendment it complies with. IFRA provides a template but does not issue or verify certificates; the supplier prepares them from the formula (IFRA certificates). To calculate the figures you need every restricted material's level in the oil, including constituents of naturals, against each category's limit — the most restrictive material decides each category's maximum (how to check IFRA limits, phototoxicity combinations).
Allergen statements
List each declarable allergen and its percentage in the oil, for the markets your customers sell in — the EU's expanded list, Canada's, and others. Your customers multiply by their use level to decide what to put on their own labels (fragrance allergens list, EU allergen labeling).
Imports and shipping
- Oils imported into the US for non-cosmetic uses need TSCA import certification (TSCA and fragrance oil imports).
- Many fragrance oils are dangerous goods in transport, by flammability or environmental hazard (flash point, how to ship perfume).
Keeping documents in step with formulas
- Every document carries the oil's code, formula version and date.
- A formula change triggers a review of every document (formula change control).
- A new IFRA Amendment or allergen rule triggers a review of every certificate and statement.
- Customers who bought the oil are told when a document changes materially.
The business side of supplying others is part of the fragrance development workflow. RUŌOD Lab keeps formulas with versions and reports, and exports them as PDF, CSV, Excel or JSON; SDS authoring and classification are done in specialist tools.
Frequently asked questions
Do I need an SDS to sell fragrance oil on a marketplace to hobbyists?
Requirements differ by market and by whether the buyer is a business or a consumer, but most fragrance oils are hazardous mixtures and platforms and customers commonly ask for one. Prepare it before you list.
Can I copy my supplier's IFRA certificate for an oil I relabel?
Only if the oil is unchanged and your agreement with the supplier allows it; the certificate must match the product. If you blend or dilute, the figures change and you must calculate your own.
What is the most common gap?
Documents that do not match the current formula version. Version the documents with the formula.
