SDS vs MSDS: Understanding Safety Data Sheets for Fragrance Products

Every B2B transaction involving fragrance compounds, essential oils, or scented consumer products should be accompanied by a Safety Data Sheet. Yet buyers still encounter the term “MSDS” in supplier communications, and confusion between the two formats persists. This article clarifies the distinction, explains the regulatory framework, and outlines what your purchasing team should verify on every document received.

The Short Answer: MSDS Is Obsolete

The Material Safety Data Sheet (MSDS) was the predecessor format used primarily in the United States under OSHA’s original Hazard Communication Standard (29 CFR 1910.1200). In 2012, OSHA adopted the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) and mandated the transition from MSDS to the standardized 16-section Safety Data Sheet (SDS). The compliance deadline for full transition was June 1, 2015.

In the European Union, the CLP Regulation (EC) No 1272/2008 and REACH Regulation (EC) No 1907/2006 (Article 31 and Annex II) require the 16-section SDS format. The term “MSDS” has no legal standing in EU documentation.

If a supplier still issues documents labeled “MSDS,” this signals either outdated compliance systems or a supplier operating outside current regulatory frameworks. Both scenarios warrant caution.

The 16-Section SDS Format

Under GHS and both OSHA and EU requirements, a compliant SDS must contain exactly 16 sections in the following order:

1. Identification - Product name, supplier details, emergency phone number
2. Hazard(s) identification - GHS classification, signal words, hazard statements (H-codes), precautionary statements (P-codes)
3. Composition/information on ingredients - CAS numbers, concentration ranges, impurities
4. First-aid measures - Exposure routes and treatment
5. Fire-fighting measures - Suitable extinguishing media, specific hazards
6. Accidental release measures - Spill containment and cleanup
7. Handling and storage - Safe handling practices, storage conditions
8. Exposure controls/personal protection - OELs, PPE requirements
9. Physical and chemical properties - Flash point, boiling point, vapor pressure, pH
10. Stability and reactivity - Conditions to avoid, incompatible materials
11. Toxicological information - Acute toxicity, skin sensitization data, LD50/LC50 values
12. Ecological information - Aquatic toxicity, biodegradability
13. Disposal considerations - Waste classification and disposal methods
14. Transport information - UN number, packing group, IATA/IMDG classification
15. Regulatory information - Applicable regulations (REACH, TSCA, CLP)
16. Other information - Revision date, abbreviations, training advice

What Fragrance Buyers Must Check

For fragrance compounds and essential oils, pay particular attention to these sections:

Section 2 - Hazard Identification. Fragrance materials frequently carry Skin Sensitization Category 1 (H317) classifications. Under EU CLP, if a preparation contains a skin sensitizer at or above 1% concentration (or 0.1% for Category 1A), the mixture itself must be classified and labeled accordingly. Verify that the hazard statements match the known allergen profile of the compound.

Section 3 - Composition. For complex fragrance mixtures, suppliers may list components as “proprietary” but must still disclose any substance classified as hazardous at concentrations above the relevant cutoff (typically 1% for health hazards, 0.1% for CMR substances under REACH Article 31). Cross-reference disclosed CAS numbers against your IFRA Certificate and allergen declaration.

Section 9 - Physical Properties. Flash point is critical for transport classification. Many fragrance compounds have flash points below 60 degrees Celsius, classifying them as Class 3 Flammable Liquids under UN transport regulations. This affects shipping costs, packaging requirements, and warehouse storage obligations.

Section 14 - Transport Information. Confirm the UN number, proper shipping name, and packing group. Fragrance compounds may ship under UN 1266 (perfumery products) or UN 1993 (flammable liquid, n.o.s.) depending on composition. Incorrect transport classification can result in customs holds and fines.

Section 15 - Regulatory Information. For EU imports, verify REACH registration status. Under REACH, substances manufactured or imported above 1 tonne per year per legal entity must be registered with ECHA. Ask your supplier for their REACH registration number or confirmation of compliance through their Only Representative.

Language and Format Requirements

In the EU, the SDS must be provided in the official language(s) of the destination member state (REACH Article 31(5)). A single English-language SDS does not satisfy requirements for shipments to Germany, France, or Italy unless the local authority accepts it. Many buyers request multi-language SDS packages from suppliers at the outset.

The SDS must be dated and include a revision number. Under REACH, suppliers must update the SDS without delay when new hazard information becomes available or when an authorization or restriction is granted.

Red Flags in Supplier Documentation

Watch for these warning signs:

• Documents still titled “MSDS” or using a non-16-section format
• Missing CAS numbers in Section 3 for declared hazardous components
• No revision date or a date older than 3 years without justification
• Generic hazard statements that do not match the product’s known composition
• Section 15 listing regulations that do not apply to the destination market

How Aromiso Manages SDS Documentation

Aromiso provides 16-section SDS documents compliant with GHS, OSHA 29 CFR 1910.1200, and EU REACH Annex II for all fragrance compounds, essential oil blends, and finished scented products. Our SDS documents are available in English, French, German, Spanish, and Chinese, with additional languages arranged upon request. Each SDS is reviewed and updated whenever formulation changes occur or regulatory amendments take effect.

Practical Steps for Your Team

1. Update your supplier qualification checklist to require a current 16-section SDS before sample approval.
2. Train your receiving warehouse staff to verify that each shipment includes the SDS matching the product code on the purchase order.
3. Store SDS documents in a searchable digital system accessible to your EHS, logistics, and regulatory teams.
4. Set calendar reminders to request updated SDS documents annually or upon notification of regulatory changes.

The SDS is not just a shipping formality. It is the foundation of your workplace safety program, your transport compliance file, and your product liability defense. Treat it accordingly.
