The evidence register

The claims the house has checked so far, as the pages make them today, each with its status: 193 sourced, 311 labelled for what they are (the house’s reading, the trade’s convention, an illustrative example), 155 unsourced. The register does not yet cover every sentence on the site. A claim marked unsourced stays on the page until a source is filed or the words change; a claim the pages no longer make leaves this list.

The molecules behind nature’s masterworks

Mysore Sandalwood

Calabrian Bergamot

  • sourced Raw bergamot contains bergapten, a furanocoumarin that can make skin sensitive to sunlight — which is why perfumery generally uses bergapten-free (FCF) grades. · Navarra M, Mannucci C, Delbò M, Calapai G

Madagascar Vanilla

  • unsourced Vanillin is the dominant aromatic compound, but natural vanilla contains hundreds of compounds that give it depth synthetic vanillin cannot match.

The Precious Materials

Perfumery 101

  • perfumery convention Every fragrance unfolds in three stages: Top notes hit first (citrus, herbs) and fade first.
  • perfumery convention Base notes linger longest (woods, musks) — often for many hours.
  • perfumery convention Parfum carries the most perfume oil and lasts longest. Eau de Parfum balances strength and longevity. Eau de Toilette is lighter. Cologne is freshest but fades fastest. The exact strengths vary from house to house.
  • house interpretation Synthetics are lab-created molecules — consistent from batch to batch. Safety depends on the material, not on where it came from.
  • perfumery convention Can range from a couple of hours (light citrus) to a full day or more (heavy ambers).
  • unsourced A foundation of the classic eau de cologne since the early eighteenth century.
  • unsourced The roots of this tropical grass are steam-distilled once the plant is well established.
  • house interpretation Hand-picked in India. Its scent was thought so heady that, the story goes, Victorian girls were warned away from it.
  • perfumery convention A foundation of the classic amber accord.
  • sourced Among the costliest natural materials in perfumery. Iris roots (orris) are dried for several years, during which irones develop. Then distilled to produce a concrete, which yields butter. · Crișan I

Where fragrance grows

  • house interpretation Many of perfumery’s great materials come from a handful of storied regions — each with its own soil, climate and centuries of expertise.

The Ingredient World Map

Raw Material Adulteration

  • house interpretation What’s sold as “sandalwood oil” is often: Australian S. spicatum (different species, different smell), synthetic santalol blends, or Indian sandalwood heavily diluted with synthetics. Buyer beware.
  • unsourced Pure Lavandula angustifolia from Provence costs far more than lavandin (a hybrid).
  • house interpretation GC-MS analysis is how it is caught; a “100% pure” label on its own proves little.
  • unsourced A perfumer designing with “jasmine absolute” that’s actually partly synthetic indole and benzyl acetate creates a different fragrance than one using genuine Grasse jasmine.
  • unsourced Difficult at low levels of adulteration
  • house interpretation Large buyers commonly test the materials they receive — but smaller perfumers often cannot afford it.

  • unsourced When you smell a rose, you’re not smelling “rose.” You’re smelling hundreds of individual molecules hitting your olfactory receptors simultaneously.
  • unsourced Rosa damascena oil contains hundreds of identified compounds, among them:
  • house interpretation It means we know exactly what we’re making — and we can make it the same way every time.
  • house interpretation Synthetics expanded the perfumer’s palette far beyond what nature could supply.
  • perfumery convention Aldehydes often smell fatty or citrusy, esters fruity, alcohols fresh, ketones sweet or powdery. A small change in structure can change the whole scent.
  • perfumery convention The pyramid follows volatility more than any rule.
  • sourced The two mirror forms of some molecules smell different. Same atoms, different arrangement, different smell. · Genva M, Kenne Kemene T, Deleu M, Lins L, Fauconnier ML
  • unsourced Your nose has several hundred types of olfactory receptors. Each molecule activates a combination of them.
  • unsourced At high concentrations, indole smells fecal — it is one of the molecules in that smell. But at the trace levels found in jasmine, it creates that heady, narcotic, almost scandalous quality that makes jasmine so intoxicating.
  • house interpretation Your nose is a remarkably fine chemical detector.
  • unsourced You have several hundred types of olfactory receptors. Each odor activates its own combination — like a barcode.
  • sourced Some people cannot smell certain molecules (specific anosmias) — Iso E Super is a well-known case. This is one reason perfume smells different to everyone. · Genva M, Kenne Kemene T, Deleu M, Lins L, Fauconnier ML
  • unsourced Smell adapts quickly. After a while you stop consciously perceiving a constant odor.
  • unsourced Much of what you call “taste” is actually retronasal smell. Block your nose, and coffee tastes like bitter water.
  • unsourced Built from isoprene units (C₅H₈), terpenes are one of nature’s largest aromatic families.

  • house interpretation A synthetic facet of ambergris, central to many recent masculine fragrances.
  • unsourced Its persistence in the environment is monitored and debated. Still used because little else smells quite like “clean.”
  • house interpretation Its generous use in Mugler’s Angel is widely credited with opening the gourmand category.
  • unsourced The bacteria living on your skin can transform some fragrance molecules into different compounds, which is one proposed reason a perfume can smell different from one person to the next. Your skin is a living surface, not a blotter.
  • house interpretation Much of a bottle’s price is marketing and packaging rather than the liquid.
  • unsourced Some fade from awareness in minutes, others take far longer. Whether the coffee beans on the perfume counter help is doubtful — they may not “reset” your nose at all.
  • unsourced It can float in the ocean for years, oxidizing into a complex, animalic-sweet material. Its legal status differs from country to country.
  • unsourced Androstenone, Iso E Super and some musks are well-known cases. For β-ionone, genetic variation changes how people perceive it.
  • house interpretation A fine fragrance can contain dozens of ingredients, a masterwork many more. But the palette available to perfumers is finite.
  • house interpretation A safer return for the brand.
  • unsourced Now largely replaced with synthetic civetone for ethical reasons.
  • unsourced From the musk pod of the male musk deer, a protected species whose trade is controlled. The “holy grail” of animalic notes, and the reason perfumery turned to synthetic musks.
  • house interpretation A complex natural with a very low yield.
  • sourced Studies have found scent-triggered memories often more emotional and older than memories cued by words or pictures; the olfactory system’s close links to the amygdala and hippocampus are the usual explanation. · Herz RS
  • house interpretation This is why challenging fragrances “grow on you.” Skanky ouds, smoky leathers, medicinal notes can become beautiful with repetition. What you dislike today may become your signature.

The Olfactory Pyramid

The Ghost Molecule

  • sourced ISo E Super (1-(2,3,8,8-tetramethyl-1,3,4,5,6,7-hexahydronaphthalen-2-yl)ethanone, molecular formula C₁₆H₂₆O) was first made in the early 1970s by the chemist John B. · PubChem Compound Summary for CID 1808124, 1-
  • house interpretation Iso E Super sits — by industry lore, no measured count — in a great many contemporary fine fragrances, Molecule 01 most famously.
  • unsourced Hall is also credited with Cashmeran.

The GC-MS Decoder

  • unsourced But gas chromatography–mass spectrometry can separate a mixture into its components and identify most of them, and houses routinely analyse each other’s launches.
  • unsourced The result is a chromatogram: each peak a compound, identified from its mass spectrum, with a rough idea of how much of it there is.
  • house interpretation A trained analyst can read much of a commercial fragrance this way. The large houses run their own instruments; independent perfumers can use university facilities or commercial analytical labs.
  • unsourced What GC-MS reveals: Most aroma chemicals present above trace levels.
  • house interpretation Houses analyse significant launches as a matter of course. Inside the industry it is called market intelligence, not espionage — and “secret formulas” are more transparent to anyone with the equipment and training than the marketing suggests.

Projection Estimator

Your Skin Changes the Formula

  • house interpretation The same formula can smell different on different people — and on the same person from one day or season to the next. One drop on a paper strip, one on skin: drawn in-house
  • unsourced Healthy skin is slightly acidic, and its chemistry varies from person to person. Perfumers commonly observe that dry skin lets a fragrance fade faster and oilier skin holds it longer; how much pH itself changes a scent is less clear.
  • unsourced It is one proposed reason two people wearing the same perfume smell different: their bacteria may transform some of its molecules differently.
  • unsourced What you eat and your hormones can change the volatile compounds your skin gives off, so a fragrance may wear differently over a week or a year. Claims that particular hormones favour particular notes go beyond the evidence.
  • house interpretation Test it on your own skin and give it time before you judge: it changes over the first minutes and hours.
  • unsourced After a few smells of the same material your nose adapts and you briefly stop noticing it. This is why perfumers step into fresh air between samples; whether the coffee beans on the counter help is doubtful.

  • perfumery convention 40% as the section states it
  • house interpretation MYTH: All “Parfum” versions are 30%+ oil
  • perfumery convention Figures below are commonly cited ranges; houses vary, and wear depends on skin and formula.
  • house interpretation Better longevity helps explain the higher price per ml.
  • house interpretation Eau Sauvage and CK One arguably work best in lighter formats.
  • house interpretation TRUTH: Many houses change formulas, sometimes substantially, between concentrations.

Formulation Secrets

  • unsourced A fragrance marketed as “100% natural” may, under some definitions, still use nature-identical molecules produced synthetically.
  • unsourced The actual aromatic concentrate — what perfumers call the “juice” — can be a smaller share of what’s in the compounding tank.
  • house interpretation When a formula is priced per kilo, that’s the concentrate; the finished product costs far less per unit volume.
  • house interpretation Niche brands may use higher concentrate percentages, but the economics limit how far they go.
  • house interpretation The spray you smell immediately after application is not fully representative of the fragrance.
  • house interpretation Some perfumers deliberately “pad” the headspace — the first moments of evaporation — with cheap, attention-grabbing notes that fade within minutes.
  • house interpretation The fuller fragrance emerges later, often after the customer has already decided.
  • house interpretation Many “natural” fragrances rely on synthetics for lift and longevity.
  • house interpretation Iso E Super is in a great many formulas — its velvety cedarwood-musk acts as a “fragrance amplifier” that makes other notes project further.
  • house interpretation A fragrance marketed as “100% natural” may, under some definitions, still use nature-identical molecules produced synthetically. The distinction is one of labelling, not smell.
  • house interpretation Perfumers rarely build fragrances note by note from scratch.
  • house interpretation 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.
  • house interpretation True ground-up composition is less common and costly.
  • house interpretation Briefs specify cost ceilings per kilo of concentrate — low for mass-market, higher for prestige, higher still for niche.
  • house interpretation “Oud” in an inexpensive fragrance is often cypriol and synthetic bases; genuine oud would strain the budget on a single note.
  • house interpretation Rose oxide and other synthetics stand in for rose absolute at a fraction of the cost.
  • house interpretation 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.
  • house interpretation This is common practice, not exceptional.
  • house interpretation Fragrances that evolve dramatically are said to test poorly in focus groups, where consumers expect the bottle to smell like what they tried.
  • house interpretation A fragrance that transforms can confuse the mass market.
  • house interpretation “Oud” is often synthetic bases. “Ambergris” is usually Ambroxan or similar.
  • house interpretation The note pyramid is largely marketing, not a formula disclosure.

Fragrance Appreciation

  • house interpretation Check at 4 hours, 8 hours, the next morning.
  • house interpretation The alcohol needs to evaporate — evaluating during this phase tells you little about the fragrance, much about ethanol.
  • perfumery convention These are the most volatile molecules, usually the lightest.
  • house interpretation Don’t judge a fragrance by its top notes alone.
  • perfumery convention Heart Notes (the next few hours)
  • house interpretation This is what you’ll smell for much of the wear.
  • house interpretation This varies wildly by person — dry skin is often said to hold scent less well than oily skin.
  • house interpretation Some fade within a few hours; others linger into the next day.
  • house interpretation Often linked with American taste; a mass-market default.

Cost Breakdown

  • house interpretation Where does the shelf price actually go? A rough sketch, not audited figures.
  • house interpretation The liquid inside a designer bottle is commonly reported to be a small part of its cost.
  • house interpretation Niche often spends more on juice, less on advertising — but margins can remain generous.
  • house interpretation That concentrate is commonly reported to cost the brand very little.
  • house interpretation A celebrity campaign can cost many millions.
  • house interpretation Prime retail placement is said to carry its own large fees.
  • house interpretation Most of what you pay for is not what is in the bottle.

Compliment Scores

  • house interpretation Fragrances often said to draw “what are you wearing?” Modeled: the house’s reading of community talk, not a measurement.

Celebrity Fragrances

  • house interpretation Many celebrity fragrances are, by most accounts, marketing exercises with little creative involvement.
  • house interpretation Here is the house’s reading of which deserve a sniff.
  • house interpretation Soft lavender, white amber, cedar — a quiet, sophisticated woody-musky scent that might be praised more widely without the “celebrity” stigma.
  • unsourced Competent fruity florals widely seen as good for the price.
  • house interpretation The series (Reb’l Fleur, Nude) was often praised for consistency — unusual for celebrity lines.
  • unsourced Involvement Level: Unclear. Public accounts of her role vary.
  • house interpretation Created, arguably, when celebrity scents were held to higher standards.
  • unsourced A sweet white floral that sold in very large numbers. Credited to professional perfumers.
  • house interpretation Much of the appeal was the bottle — the scent sits close to many competitors.
  • unsourced Involvement Level: Reportedly low. Accounts suggest she chose from submissions, with marketing leading.
  • house interpretation The pattern, as widely described: pay the celebrity a large fee. Offer a handful of submissions. Minimal creative input. Launch with heavy marketing. Sell hard in year one. Discontinue when sales drop. Repeat with the next celebrity.
  • house interpretation Reality: Many celebrity fragrances appear to exist mainly as marketing vehicles. The liquid can seem almost incidental.

Perfume Controversies

  • house interpretation Leaked formulas, authorship quarrels and regulatory fights. Darker chapters of the perfume industry that PR departments rarely discuss.
  • house interpretation These accounts summarise what is commonly reported; details are disputed and not verified here. Draw your own conclusions.
  • house interpretation Rival houses · a recurring risk
  • unsourced Formula theft between rival houses is a recurring fear in the trade; one leaked formula can represent years of development work.
  • house interpretation It shows how vulnerable the industry is: formulas are trade secrets, not patents.
  • house interpretation A house notices a rival winning briefs with suspiciously similar compositions
  • house interpretation An internal investigation hunts for the leak; access and staff are reviewed.
  • house interpretation Cases of this kind can end in confidential settlements, with responsibility left unclear.
  • house interpretation Major houses guard formulas closely. Digital access controls, compartmentalized formula access and non-compete clauses are common. Trust between competitors is said to be low.
  • unsourced For decades, the popular story often implied Coco Chanel created No. 5 herself.
  • sourced In reality, Ernest Beaux created it, reportedly adapting an earlier formula linked to the Russian Imperial court. · Osmothèque, Conservatoire international des parfums
  • unsourced Chanel’s contribution, as the story goes, was choosing sample No. 5 from a lineup.
  • unsourced Ernest Beaux reportedly presents Chanel with numbered samples. She chooses No. 5.
  • unsourced 5” — Beaux’s name largely absent from marketing
  • unsourced Brand storytelling tends to centre Chanel’s “vision” — Beaux often a footnote
  • house interpretation Frédéric Malle’s “Éditions de Parfums” stood out largely because it credited perfumers publicly.
  • unsourced In the 2000s, IFRA (International Fragrance Association) severely restricted oakmoss — the foundation of the chypre family — due to allergen concerns.
  • unsourced Some critics argue that IFRA’s members include makers of synthetic replacements, a conflict of interest in their view.
  • unsourced Some commentators have questioned the evidence for the restriction level.
  • house interpretation Further restrictions added. Classic formulas can no longer be made to IFRA Standards as originally composed.
  • unsourced IFRA is an industry body funded by its member companies, some of which make synthetic replacements.
  • house interpretation “Natural” fragrances can contain mostly synthetics.
  • house interpretation The disconnect between marketing and reality is widespread.
  • house interpretation Example: a costly “oud” fragrance may contain no real oud at all. Synthetic oud bases are cheap; real oud oil is famously expensive.
  • sourced Labels need not disclose the formula beyond “fragrance” or “parfum”, though the EU requires named allergens. Consumers rarely know the full contents. · Regulation (EC) No 1223/2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products (recast)
  • unsourced Unlike food or pharmaceuticals, fragrance has no full-formula disclosure. The industry treats formulas as trade secrets.

Dupe Database

  • modeled Shared-DNA notes are drawn from published note breakdowns and side-by-side wear testing; similarity figures are modeled: the house’s reading of overlap, not a measurement.
  • house interpretation Both seem built on a similar pineapple-birch-ambroxan skeleton. CDNIM reads more synthetic, with a slightly sharper, less nuanced opening. The drydowns come close. Most of the difference shows in the opening.
  • house interpretation Cloud echoes BR540’s ethereal, skin-scent quality, apparently through similar ambery and musky materials.
  • house interpretation Both are commonly reported to rely on synthetic oud accords rather than natural oud.
  • house interpretation In side-by-side wearing, even experienced noses can struggle to tell them apart in the drydown.
  • house interpretation Base performance is comparable — both are long-lasting. Most of the difference lies in the spices.

Clone Chemistry

  • unsourced A fragrance sample is vaporized and passed through a column that separates components by volatility and polarity.
  • house interpretation A skilled analyst can reconstruct much of a formula from GC-MS data alone.
  • house interpretation Small differences in amount are hard to read from the peaks.
  • unsourced Javanol, Hedione HC, Clearwood — these appear on the chromatograph, but they can be hard to buy outside Givaudan or Firmenich.
  • house interpretation It’s partly why clones often smell “almost right” but miss something ineffable.
  • unsourced The rose absolute in Chanel is reported to come from specific Grasse suppliers with multi-decade relationships.
  • house interpretation 5 has been cloned countless times; few, if any, capture the original.
  • house interpretation Mitsouko clones are widely found disappointing. Complexity resists reverse engineering.
  • house interpretation The industry prefers secrecy to courtrooms; a lawsuit could require disclosing the formula you’re trying to protect.
  • house interpretation A very cheap “Aventus dupe” and a costlier specialized recreation are not comparable products.

Focus Group Manipulation

  • house interpretation Focus groups often evaluate fragrances in brief exposures — long enough to smell the headspace, nowhere near long enough to evaluate dry-down.
  • house interpretation This tends to favor top-heavy compositions with aggressive, attention-grabbing openings.
  • house interpretation 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.
  • house interpretation A fragrance that half love and half hate scores poorly — it’s “polarizing.” A fragrance everyone finds “pleasant” but nobody loves scores well.
  • house interpretation This methodology tends to weed out bold compositions in favor of inoffensive mediocrity.
  • unsourced Angel reportedly tested poorly; it succeeded partly because Thierry Mugler backed it anyway.
  • house interpretation “Too strong,” “too sweet,” “smells old” — these vague descriptors can drive reformulations that strip character.
  • house interpretation Perfumers must interpret untrained responses, sometimes incorrectly. The gap between what consumers say and what they mean can be wide.
  • house interpretation Focus groups tend to be run in a handful of key markets.
  • house interpretation 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.
  • house interpretation The focus group process tends to push global fragrance toward common-denominator preferences.
  • unsourced Houses such as Frédéric Malle, Serge Lutens and Comme des Garçons are often cited as releasing what their perfumers create, with little consumer testing.

Sample Sets

  • house interpretation These discovery sets offer good value and variety. Ratings are modeled: the house’s reading, not a measurement.

The Brief Economy

  • house interpretation The budget constrains almost everything. The brief determines less than you might think. The creative team’s instincts can survive or die on a focus group that smells for seconds.
  • house interpretation A fragrance brief usually includes a cost target — expressed per kilo of finished concentrate. This single number shapes almost everything. A low budget cannot support much real rose absolute, one of the costliest materials. A moderate budget opens real…
  • house interpretation A brand gives perfumers a few pages of mood-board imagery, a “spirit” paragraph (“a confident woman who runs her own company, modern Paris, leather and gardens”), a demographic target, a bottle concept, and the cost target.
  • house interpretation The creative direction can be contradictory.
  • house interpretation Each may submit several interpretations. The brand often evaluates blind on smelling strips.
  • house interpretation This translation is often imperfect. A perfumer may go through many rounds of iteration before launch or cancellation.
  • house interpretation Panels of consumers may evaluate the final candidates, often in brief sniffs on paper strips in testing centers. The complexity of drydown, sillage and skin interaction can be largely missed.
  • house interpretation A story often told in the trade: dozens of rounds of changes on a fragrance the perfumer was proud of, then cancellation because someone senior did not like it. The perfumer’s instinct survives only when someone upstream has the courage to protect it.

Perfumer Ownership

  • house interpretation The perfumer whose name appears on a press release usually owns nothing. The formula typically belongs to the supplier house. The creative work is generally work-for-hire. Any royalties usually go to the supplier, not the creator. This is the invisible…
  • house interpretation Perfumers employed by fragrance suppliers (Givaudan, Firmenich, IFF, Symrise) receive a salary that rises with seniority and varies by country. They typically sign IP assignment agreements when hired. The formulas they create generally belong to their…
  • house interpretation Independent perfumers who sell directly to consumers generally retain ownership of their formulas.
  • house interpretation If a formula is licensed to a brand, royalty terms vary and are rarely published.
  • house interpretation The big houses provide a steady salary, costly equipment, access to proprietary captive molecules, and development infrastructure that an independent would struggle to replicate alone.
  • house interpretation The Captive Molecule Problem: The Big Four supply houses each own proprietary aroma chemicals often unavailable outside their supply chain.
  • unsourced Examples include Firmenich’s Norlimbanol and Firsantol.
  • house interpretation This captive material system is widely seen as one of the strongest competitive moats in the industry.

Blind Buy Risk

  • house interpretation Some fragrances are safer blind buys — crowd-pleasers with broad appeal.

Application Masterclass

  • house interpretation For most situations, three or four sprays is plenty.
  • house interpretation Your nose adapts (olfactory fatigue), but others may still smell it clearly.
  • house interpretation Test: If you can smell yourself all day, you have probably over-applied.
  • house interpretation Skin warmth lifts the top notes and lets the scent develop.
  • house interpretation Rubbing wrists together is an old habit worth dropping. Many say the friction dulls the top notes.
  • house interpretation Give the alcohol a moment to evaporate.
  • house interpretation It wastes most of the juice.
  • house interpretation Apply after a shower, when skin is warm and slightly damp.
  • house interpretation Moisturized skin holds fragrance longer — unscented lotion first can help it last longer.
  • house interpretation Apply a little while before leaving.
  • modeled Pulse Points, Ranked (Modeled: the house’s reading, not a measurement)
  • unsourced Olfactory fatigue (nose blindness) sets in fairly quickly.
  • unsourced Your brain turns down a constant smell to stay alert to new ones — probably a useful survival trait.
  • unsourced Others can usually still smell it.

  • house interpretation Two or three sprays usually stay close.
  • house interpretation Powdery iris that stays close to the skin.
  • house interpretation Widely liked, rarely aggressive. Even so, go lightly where colleagues are sensitive to scent.
  • house interpretation Love it or hate it, people will notice it. A single spray carries a long way. Better kept for after-work events.

Olfactory Illusions

  • house interpretation Perfumers may stack several versions of a key note — several musks, more than one sandalwood-like material — so that someone who misses one may still smell another.
  • unsourced Some fragrances affect the trigeminal nerve — the nerve that carries temperature and pain sensation in the face.
  • unsourced Pink juice tends to be perceived as “sweeter”; amber juice as “warmer”; blue juice as “fresher.” Brands make careful use of this.

The nose behind the house
