Perfume Lab Safety Basics: Ventilation, Handling and Storage

Flammability

Ethanol is highly flammable, and its vapor can ignite from a flame, a spark or a hot surface some distance from the open container. Many essential oils and aroma chemicals are flammable too.

• No open flames, smoking, gas burners or hot plates near open alcohol or materials.
• Keep containers closed when not in use; vapor builds up in still air.
• Store alcohol and flammable materials in closed containers, away from heat and sunlight, in modest quantities. Local fire codes may limit how much you may keep, especially at home.
• Keep a suitable fire extinguisher accessible and know how to use it.
• Check each material's flash point on its safety data sheet.

Ventilation

Working with fragrance materials all day exposes you to vapors, and some materials are irritating at high concentrations. Work in a well-ventilated room, ideally with extraction near the weighing area. Ventilation also protects your evaluations: a room saturated with fragrance is a poor place to smell anything.

Skin and eyes

Many fragrance materials can irritate skin or eyes when concentrated, and some are skin sensitizers: repeated contact can lead to an allergy that then reacts to tiny amounts. Sensitization is long-lasting, and for a perfumer it can be career-limiting.

• Wear nitrile gloves when handling neat materials, and change them when contaminated.
• Wear safety glasses when pouring, decanting or working with anything that could splash.
• Do not test neat materials on skin; evaluate on blotters, in dilution.
• Wash off spills on skin promptly with soap and water.
• Know where the eyewash or a clean water source is.

Safety data sheets

Every material should have a current safety data sheet on file, from the supplier. It gives the hazards, handling precautions, protective equipment, storage requirements, first aid, and what to do with spills and waste. Read it when a material arrives, not after an incident. Safety data sheets, specifications and CoAs explains what to look for.

Labeling and storage

• Label every container — including dilutions and decanted working bottles — with the name, code, concentration, date and hazard information where required.
• Never store fragrance materials in food or drink containers, or in a refrigerator used for food.
• Keep materials out of reach of children and pets.
• Store incompatible materials apart, as their safety data sheets advise.
• Store sensitive materials cold and dark; see fragrance raw material shelf life and storage.

Spills and waste

Keep absorbent material and a closable container for spills. Absorb, ventilate, and dispose of contaminated material as the safety data sheet advises — not down the drain in quantity. Small amounts of used blotters and gloves can usually go out with general waste once solvents have evaporated, but check local rules for disposing of flammable and chemical waste.

Personal habits

• No eating or drinking at the bench.
• Use a fresh pipette per material; never mouth-pipette.
• Take breaks: olfactory fatigue makes it easier to over-expose yourself without noticing.
• Keep the bench clear; clutter causes spills.

Lab safety is not product safety

Everything here is about protecting the people working in the lab. Whether a finished product is safe for consumers is a separate question, answered by the IFRA Standards, market regulations and a product safety assessment — see the IFRA Standards guide. How safety fits into the layout and routine of a lab is covered in how to organize a perfume formulation lab.

The same flammability that matters in the lab governs how perfume can be shipped; see how to ship perfume.

Frequently asked questions

Do I need a fume hood?

Most small perfume labs manage with good general ventilation and local extraction near the bench. A fume hood is worth considering if you handle large quantities, heat materials, or work with particularly volatile or hazardous ones.

Is it safe to smell materials neat?

It is better practice to smell in dilution on a blotter, held at a short distance. Neat materials can be overwhelming and irritating, and dilution tells you more about how they will behave in a formula.
