Scent as Craft: Your First 50 Perfume Materials

What every aspiring perfumer should smell first — and why.

When you begin to study perfumery, the temptation is to buy everything. Small bottles with mysterious names—Iso E Super, coumarin, Hedione—arrive, and suddenly your desk looks like a miniature chemistry lab. Then you discover that 30ml of Aldehyde C-12 MNA will outlive your entire perfumery career and Pineapple Compound in pure strength will make your relatives disown you. (There is a reason perfumers keep it in a special space called The Stinky Room.)

At IFF’s perfumery school, our beginner kit contained around 360 core materials. Even that, Jean-Claude Ellena once told us during a visit, might be too much. He recommended a smaller, sharper palette of materials you can truly learn, not just own.

This is my adaptation of that idea:
Fifty fundamental materials every student of perfumery should smell. Think of them as the alphabet of scent, the letters you will later use to write your own perfume stories.

My focus here distills my teaching practice to its essentials. Perfumery, like any creative discipline, demands time, patience, repetition—and a willingness to invest in your senses. But the approach itself is intentionally simple. One of my students once followed this exact method while serving on combat duty in eastern Ukraine. If he could carve out moments to study a blotter between night shifts and alarms, then most of us, in calmer circumstances, can trust that this path is manageable.

The list is grouped by the role each material plays in a composition.

I. Foundations

(The bones of a composition: structure, clarity, diffusion.)

Citrus & Fresh

• Bergamot oil

• Lemon oil

• Sweet orange oil

• Grapefruit oil

• Petitgrain oil

• Mandarin oil

• Aldehyde C-10 (Decanal) — buy the smallest amount; study at 0.1% dilution

• Citronellal

• Neroli oil — expensive; a 5–10% dilution is fine for study

• Dihydromyrcenol

Why these matter:
They teach brightness, proportion, and sparkle. At IFF, these are “Box 1 and 2” materials—your first building blocks. The aldehydes appear much later in training (Box 27), but C-10 is worth learning early for its power and clarity.
