How to make perfume: a beginner’s first experiment

What you need to make perfume

The Institute for Art and Olfaction’s primer lists the tools most used in perfume labs: pipettes, scent strips, scales and glassware. For a first trial, have these ready:

• A digital scale that reads to 0.01 g or better. The Institute uses one that reads to 0.001 g and says 0.01 g is acceptable.
• Glass vials or bottles with caps, for working stocks, trials and the finished batch.
• Disposable transfer pipettes, a fresh one for each material, to move small amounts of liquid without pouring.
• Scent strips, also called blotters, for smelling materials and trials.
• Labels, and a notebook or the formula builder, for the formula and the masses you actually weigh.
• Gloves and eye protection, as each supplier’s safety data sheet requires. The Institute’s primer says to wear gloves whenever you handle materials directly, such as when blending or making dilutions.
• Perfumer’s alcohol, or another carrier whose supplier documents what it contains. Lesson 08 explains why the name on the label is not enough.

Then choose a small palette. The eight materials below come from the citrus, floral, woody, musk and gourmand families in our library, and each links to its entry and supplier source. Your first experiment needs only three or four of them. The family and note role in brackets come from each entry; they are learning labels, not fixed classifications.

• Bergamot, bergapten-free (citrus, top): sweet citrus with a faint balsamic edge.
• Linalyl acetate (citrus, top / heart): fruity floral, suggesting bergamot and pear.
• Linalool (floral, top / heart): floral citrus with orange, rose and waxy facets.
• Phenethyl alcohol (floral, heart): rose with honey-like sweetness and bready facets.
• Methyl dihydrojasmonate (floral, heart / base): transparent jasmine-like floral with citrus facets.
• Iso E Super® (woody, heart / base): soft wood and amber with a smooth character.
• Ethylene brassylate (musk, base): sweet, powdery musk with floral and woody facets.
• Vanillin (gourmand, base): sweet, creamy vanilla, supplied as crystals or as a labelled stock solution.

How to make perfume in five steps

Every trial in this course follows the same five steps, and every quantity is a mass in grams. The linked tools do the arithmetic, and the formula builder and blotter journal save your records in this browser.

1. Choose the materials and record them. Write down each one’s name, supplier grade and lot, and whether you have it neat or as a stock, in a notebook or the formula builder.
2. Make documented dilutions by mass. Weigh each working stock to a recorded strength, such as 10% w/w, and label it with the material, strength, solvent and date; the dilution calculator gives the grams of material and solvent.
3. Blend a trial by parts and weigh it. Write the formula in parts, convert it to grams for a small trial in the formula builder, and record the mass you actually add for each line.
4. Dilute the concentrate into the carrier to a recorded percentage by mass. The batch calculator works out the grams of concentrate and carrier; write the percentage on the label.
5. Label the bottle with its batch ID and date, then evaluate it on blotters over time. Record what you notice at each check in the blotter journal, so the notes stay connected to the formula.

A worked example by mass

The numbers below show how the quantities fit together. They are arithmetic, not a recommendation for particular materials or for a particular strength.

Start with a 10 g trial of concentrate from three materials at 60, 30 and 10 parts. The parts total 100, so each part is 0.1 g: weigh 6 g, 3 g and 1 g. If the 1 g line is a 10% stock, it holds 0.1 g of the material and 0.9 g of solvent, and both belong in the record.

Now plan a 100 g finished batch at 20% concentrate by mass (20% w/w). The concentrate is 100 × 0.20 = 20 g, and the carrier is the remaining 80 g. To make 20 g of the same concentrate, double the trial: 12 g, 6 g and 2 g.

The 20% is a share of the finished batch, not of the carrier. Adding 20 g of concentrate to 100 g of carrier gives 120 g, and 20 ÷ 120 × 100 is about 16.7%.

The percentage you choose is a decision for your formula. The perfume concentration chart shows the ranges perfume houses publish for names such as eau de toilette and eau de parfum. Those ranges overlap, and the houses do not always say whether they are by mass or by volume.

Making perfume at home: what changes

At home, set up away from where food is prepared or eaten, on a surface you can clear and wipe down. Keep food, drink, children and pets away while you work, and keep bottles capped between transfers.

Work in a well-ventilated room. The Institute for Art and Olfaction describes ethanol, sometimes called perfumer’s alcohol, as highly flammable: keep it away from flames and electrical sources, and do not leave a container of it open for long. Do not heat an alcohol trial.

Read the safety data sheet for every material and for the carrier before you open them, and follow its handling, storage, protective-equipment and first-aid sections. When you discard a trial, do not pour it down the sink; the Institute’s primer says to keep it in a stable container and take it to a facility that handles chemical waste.

Keep batches small: large enough for your scale to measure the smallest line, and no larger. A small batch uses less material and leaves less flammable liquid on the bench.

Nothing in this lesson says a blend is suitable for skin. A blotter shows how a trial smells on paper. Wearing a perfume or giving it to someone needs the assessment described under “Know the next milestone” below.

Start with an experiment you can explain

A productive first session has a narrower goal than “make a beautiful perfume.” Try “compare three rose materials” or “find out how a fruity floral changes a jasmine sketch.” You should be able to name the thing you are changing and the observation you hope to make. That turns an enjoyable afternoon into knowledge you can use in the next formula.

Choose three or four materials with clear identities and accessible supplier documentation. A small set makes mistakes easier to diagnose and gives you time to learn each material. An expanding collection is useful only when your observations grow with it. You do not need an ingredient for every note family before you can begin.

Build the working space around accurate records

Use a stable scale, labelled glass containers, scent strips, transfer pipettes and a notebook or formula record. Match the batch size to what your scale can reliably measure; the last displayed decimal does not automatically represent an accurate measurement. A clean, level surface and a repeatable weighing process matter more than an elaborate bench.

Read each material’s supplier safety data sheet before handling it, and follow its handling, ventilation, storage and protective-equipment instructions. Keep bottles capped between transfers and keep food, children and pets away from the work area. These are working ingredients, including when their names sound familiar from flowers or foods.

1. Give the experiment an ID such as ROSE-001 and write one sentence stating its purpose.
2. List the exact materials, supplier grades, stock strengths and solvents.
3. Label the trial container and blotters before transferring any material.
4. Create a planned formula and leave a separate place for the masses actually weighed.

Learn a material before asking it to blend

Study each material separately at a documented evaluation dilution appropriate to that material and its supplier guidance. A working stock is not an instruction to apply it to skin. Smelling an unknown concentrated bottle gives you a poor comparison with a diluted strip and can overwhelm the session.

Write your own words before looking at the supplier’s odor description. “Green, slightly waxy, reminds me of a florist” is a useful observation. “Good” is a preference without much information. If a material seems faint, record that and return later instead of repeatedly moving it closer to your face.

Make one controlled variation

Begin with a simple ratio on paper. For example, an imaginary three-material study could use 60, 30 and 10 parts. Those parts become 60%, 30% and 10% because they total 100. A 10 g trial would require 6 g, 3 g and 1 g of the specified inputs. This is arithmetic, not a recommendation for a particular ingredient combination.

For the next version, change one balance. Moving five parts from the first ingredient to the second produces 55:35:10. The total stays at 100, making comparison straightforward. Changing every ingredient at once may produce an interesting result, but it makes the cause harder to identify.

Compare over time, then keep the evidence

Give both trials the same evaluation treatment: same dilution basis, similar strip loading, matching observation times and the same room. Note what dominates at first, what emerges later and what remains at the final observation. Top, heart and base are helpful ways to describe this development; they are not three sealed compartments.

Keep the less successful trial in your record. It explains why the next version exists. Write a decision such as “Version B is too fruity after one hour; next trial lowers benzyl acetate while preserving the floral core.” A precise next action is more valuable than declaring a version finished after one sniff.

Know the next milestone

Your first milestone is a reproducible study and a clear observation. A personal fragrance or saleable product adds further work: concentration, compatibility, stability, packaging and an appropriate safety and regulatory assessment. Our educational accord sketches have not completed that work. Treat them as exercises for learning relationships between materials.

Use the formula builder to turn a ratio into a batch record, and use the blotter journal to keep the formula and the observations connected. After a few controlled studies, you will have a small library of decisions that belongs to your own nose.
