The Trade

Some commercial concentrates carry a share of diluent (often dipropylene glycol or isopropyl myristate) even before alcohol dilution. The actual aromatic concentrate — what perfumers call the “juice” — can be a smaller share of what’s in the compounding tank. When a formula is priced per kilo, that’s the concentrate; the finished product costs far less per unit volume. Niche brands may use higher concentrate percentages, but the economics limit how far they go.

The spray you smell immediately after application is not fully representative of the fragrance. Some perfumers deliberately “pad” the headspace — the opening moments of evaporation — with cheap, attention-grabbing notes that fade within minutes. The goal is to impress during the brief moment someone tests in-store. The fuller fragrance emerges later, often after the customer has already decided.

Many “natural” fragrances rely on synthetics for lift and longevity. Iso E Super is in a great many formulas — its velvety cedarwood-musk acts as a “fragrance amplifier” that makes other notes project further. Ambroxan serves similarly. A fragrance marketed as “100% natural” may, under some definitions, still use nature-identical molecules produced synthetically. The distinction is one of labeling, not smell.

Perfumers rarely build fragrances note by note from scratch. They work from pre-built accord skeletons — base formulas representing “rose accord,” “amber accord,” “leather accord.” These may contain dozens of ingredients each, balanced over years of refinement. A “new” fragrance often means combining existing accords in novel ratios, adding a distinctive top note, and adjusting for the brief. True ground-up composition is less common and costly.

Briefs specify cost ceilings per kilo of concentrate — low for mass-market, higher for prestige, higher still for niche. Perfumers become masters of illusion, creating the impression of expensive materials using cheap substitutes. “Oud” in an inexpensive fragrance is often cypriol and synthetic bases; genuine oud would strain the budget on a single note. Rose oxide and other synthetics stand in for rose absolute at a fraction of the cost.

Modern perfumers often use several different musks in a single formula, each covering different facets of the musk spectrum and compensating for partial anosmia in the population. Galaxolide (white musk), Habanolide (warm), Ethylene Brassylate (powdery), Muscone (animalic) — stacked together, they help ensure most people smell something, even if specific receptors are missing. This is common practice, not exceptional.

Many modern fragrances are deliberately linear — smelling the same from first spray to dry-down. This isn’t laziness; it’s strategic. Fragrances that evolve dramatically are said to test poorly in focus groups, where consumers expect the bottle to smell like what they tried. A fragrance that transforms can confuse the mass market. Linearity is a feature for commercial success, not a flaw.

Marketing lists notes that may not exist in the formula at all. “Saffron” is often Safraleine or Safranal at trace levels. “Oud” is often synthetic bases. “Ambergris” is usually Ambroxan or similar. Worse: some listed notes are pure invention — “lunar essence” or “desert wind” — creating olfactory placebo effects. The note pyramid is largely marketing, not a formula disclosure. Perfumers and marketers operate in different realities.

Gas Chromatography-Mass Spectrometry is the clone maker’s primary tool. A fragrance sample is vaporized and passed through a column that separates components by volatility and polarity. Each peak represents a compound; the mass spectrometer identifies it. A skilled analyst can reconstruct much of a formula from GC-MS data alone. The catch: proportions are estimated, not measured. Small differences in amount are hard to read from the peaks. Getting ratios right requires extensive testing.

GC-MS identifies what’s in a fragrance — but captive molecules may not be available for purchase. Javanol, Hedione HC, Clearwood — these appear on the chromatograph, but they can be hard to buy outside Givaudan or Firmenich. Clone makers must substitute with available alternatives. Ebanol for Javanol. Standard Hedione for Hedione HC. These swaps are close but not identical. It’s partly why clones often smell “almost right” but miss something ineffable.

Natural ingredients vary batch to batch. The rose absolute in Chanel is reported to come from specific Grasse suppliers with multi-decade relationships. A clone maker sources from available brokers; the rose smells different. Vintage formulas compound this — they used materials that may no longer exist, or exist only in forms restricted by the IFRA Standards (the industry’s own rules) or by EU law. A house that follows IFRA could not use the oakmoss of older Mitsouko at the same level today.

Some fragrances resist duplication. Chanel No. 5 has been cloned countless times; few, if any, capture the original. Why? Likely proprietary aldehyde blends, specific jasmine and rose sources, decades of formula tweaking, and the ineffable balance Beaux achieved. The simpler the formula, the easier the clone. Acqua di Giò clones can be excellent. Mitsouko clones are widely found disappointing. Complexity resists reverse engineering.

Focus groups often evaluate fragrances in brief exposures — long enough to smell the headspace, nowhere near long enough to evaluate dry-down. This tends to favor top-heavy compositions with aggressive, attention-grabbing openings. Subtle fragrances that reveal themselves over hours often struggle in focus groups. The method tends to select for loudness, not quality. Many perfumers know this and design accordingly.

Focus groups measure average approval across the sample. A fragrance that half love and half hate scores poorly — it’s “polarizing.” A fragrance everyone finds “pleasant” but nobody loves scores well. This methodology tends to weed out bold compositions in favor of inoffensive mediocrity. Angel reportedly tested poorly; it succeeded partly because Thierry Mugler backed it anyway.

Consumers often lack vocabulary to articulate olfactory experience. “Too strong,” “too sweet,” “smells old” — these vague descriptors can drive reformulations that strip character. When a focus group says “smells old,” they may mean oakmoss (heritage material) or simply unfamiliarity. Perfumers must interpret untrained responses, sometimes incorrectly. The gap between what consumers say and what they mean can be wide.

Focus groups tend to be run in a handful of key markets. Fragrances that perform in those markets advance; those with only regional appeal are often dropped. A fragrance one market adores but another finds “strange” may never launch globally. The focus group process tends to push global fragrance toward common-denominator preferences.
