Patricia de Nicolaï — Euronews report, 2017

A perfume’s name can survive after its scent has disappeared. A bottle, an advertisement, a perfumer’s name, a release year: these clues can tell us about a creation without allowing us to smell it. Discontinued perfumes are not the only ones affected. Even fragrances sold for many years may change as materials and manufacturing conditions evolve.

The Osmothèque in Versailles, France, preserves perfumes themselves and the formulas and materials that produced them. Officially the International Perfume Conservatory, it is a place where perfumers serve as guides to history, transferring scents preserved in bottles onto blotters to share with visitors.

Its beginnings lie in one perfumer’s experience of compounding old fragrances again.

Essential Information

  • Name: Osmothèque / Conservatoire International des Parfums
  • Organization: A nonprofit association under France’s 1901 law
  • Key founders: Jean Kerléo and fellow perfumers committed to preserving perfume
  • Founding agreement: October 13, 1988; opening and inauguration on April 26, 1990
  • Address: 8 rue Saint-Simon, 78000 Versailles, France
  • President: Thomas Fontaine, who succeeded Patricia de Nicolaï in 2020
  • Official website: Osmothèque

The name Osmothèque derives from the Greek word for smell, osmē, and a term for a place of storage. Neither a perfume shop nor a school, it is a place to collect, study, and transmit the memory of scent.

Jean Kerléo and the Attempt to Recover Lost Perfumes

Recompounding Patou’s Earlier Creations from Original Formulas

Jean Kerléo was born into a farming family in Brittany in 1932. At 23, he joined Helena Rubinstein’s laboratory and learned under perfumer Jacques Jantzen. His work included fragrancing cosmetics, and in 1967 he became Jean Patou’s perfumer. Alongside creating new perfumes such as Mille and Sublime, he recompounded twelve older fragrances using original formulas preserved by Patou.

A perfumer creating new work reads the formulas of earlier creators. They may contain proportions he would not choose today or materials unfamiliar to him. Kerléo’s experience showed that understanding older perfumes requires more than learning their names: it means engaging with their actual composition and smell.

Another catalyst was Millot’s Crêpe de Chine. A man named Dubois entrusted Kerléo with the formula for this 1925 perfume. Regretting the disappearance of the brand and its creations, he challenged him to see whether an old perfume could be brought back. In Osmothèque perfumer Emmanuelle Giron’s later account of the institution’s origins, this act of trust appears as an important turning point.

Work to classify perfumes and document their history was also underway in the perfumers’ association’s technical committee. Kerléo’s individual experience of recompounding joined a wider effort to preserve the profession’s memory. Jean-Claude Ellena, Guy Robert, Janine Mongin, and Yuri Gutsatz also participated in the early initiative.

From the 1988 Agreement to the 1990 Opening

On October 13, 1988, three parties signed a founding agreement: the French Society of Perfumers and its technical committee, the French Perfume Committee, and ISIPCA, the educational institution of the Versailles Chamber of Commerce and Industry. The project combined specialist knowledge, connections with the perfume industry, and a setting for education and preservation.

The Osmothèque opened at ISIPCA in Versailles on April 26, 1990. Two years separated the agreement supporting the project from the opening of the conservatory. Kerléo was its first president. Perfumer Patricia de Nicolaï succeeded him in 2008, followed by Thomas Fontaine in 2020.

This was not a matter of displaying a finished collection once and leaving it at that. The institution sought cooperation from brands, fragrance companies, and those who had inherited formulas, searching for past perfumes while accepting contemporary releases. Today’s perfumes entering the collection would themselves become history for the next generation.

What Must Be Kept to Preserve a Scent?

Protecting the Liquid, the Formula, and the Materials

Keeping the liquid alone cannot preserve a perfume forever. The Osmothèque controls light, temperature, and exposure to air, using brown storage bottles and refrigeration at approximately 12°C. The inert gas argon limits contact with oxygen and slows deterioration. Staff also regularly check the smell and remaining quantity.

On arrival, a perfume’s brand, name, release year, and concentration are recorded and an identification number assigned. Whether it is an eau de toilette or eau de parfum is part of preserving the creation accurately. Preserving the appearance of a beautiful retail bottle and managing scents used in research and classes serve distinct purposes.

A formula is a blueprint listing materials and their quantities. Even as the liquid diminishes, having the necessary materials and expertise makes it possible to weigh and blend it again. A formula alone, however, is not enough. If materials used at the time have disappeared, reproducing the proportions on paper does not reproduce the scent.

The Osmothèque therefore preserves rare natural ingredients, synthetic ingredients, and bases as well as perfumes. A base is a perfumery material made by combining several ingredients in advance. A trade name in one line of an old formula may itself require another formula and further materials. Preserving perfume also means preserving the history of its ingredients.

An official March 2026 announcement described a collection exceeding 6,000 items, comprising perfumes, materials, and rare bases. By keeping even the materials underlying a fragrance, the institution seeks to transmit both its scent and the conditions of its creation to future generations.

Original Formulas Are Not Public Documents

We are only the custodians.

Jean Kerléo — Osmothèque newsletter no. 57, November 2011, published English translation

Entrusting a formula to the Osmothèque does not transfer its ownership. Formulas remain the depositor’s property and are held under confidentiality arrangements. Access procedures govern formulas stored in a bank vault, and people authorized by the owner undertake their preservation and recompounding.

The arrangement does not allow ordinary visitors to read formulas or withdraw them for commercial use. It opens opportunities to discover scents while honoring commitments to creators and rights holders. That trust makes it possible to safeguard a brand’s precious formulas for another era.

Entering the collection and depositing an original formula are also different things. Some perfumes enter through donations of current products; others are recompounded from formulas. An increase in collection size cannot be interpreted as meaning that every corresponding original formula has been preserved.

Scents That Can Be Recreated—and Those That Cannot

Clues to Materials in Callot Sœurs Perfumes

In 2011, Kerléo discussed Callot Sœurs’ L’Eau de Verveine, dating from around 1925, and Mariage d’Amour from 1947. They had been recompounded using formulas from Antoine Chiris in Grasse, entrusted by a former perfumer who wished to remain anonymous.

Some ingredients in Mariage d’Amour were marked “ND Chiris.” ND stood for “Notre Distillation,” indicating the company’s own distilled product. This identifies not only the material but the quality supplied by a particular source. Recompounding is not simply copying ingredient names and numbers.

For Paul Poiret’s Parfums de Rosine, meanwhile, only eleven of the 36 creations Kerléo mentioned in 2011 could be recompounded, because certain bases and ingredients were missing. This historical example shows clearly that even a surviving formula does not make every scent recoverable.

Not Making a New Interpretation with Substitutes

The Osmothèque’s official policy emphasizes recompounding according to original formulas. If the required materials cannot be obtained, it does not present a reinterpretation using substitutes as a reconstruction. It distinguishes the conservatory’s work from inventing a new scent in the original creator’s place.

That does not mean simply waiting when a material is unavailable. The 2017 charter also identifies a role in research with scientists to reproduce materials no longer commercially available. Using preserved materials, recovering the materials themselves, and adapting a perfume for contemporary use with different ingredients are distinct activities.

Smelling a recompounded perfume also differs from smelling a bottle surviving from the original period. Guided by the formula, the work investigates material quality and manufacturing methods to approach the scent as created. Natural materials vary by harvest and quality, and interpreting old terminology requires expertise. The Osmothèque’s value lies less in promising to erase the distance of time than in continuing to work carefully across it.

Official introductions also cite Coty’s Chypre (1917) and Jacques Fath’s Iris Gris (1947) as examples from the historical collection. In 2023, Fontaine also discussed recompounding fragrances including Shocking (1937). The collection is sustained not merely by retaining bottles but by weighing materials anew and evaluating their scent.

Osmothécaires Connect Scent with History

The specialists who manage and present the Osmothèque’s scents are called osmothécaires. Predominantly perfumers, they also include chemists, historical researchers, and specialists in communicating scent. Sourcing and organizing materials, recompounding, checking condition, researching historical documents, and preparing classes: those who preserve scents are also those who share them.

Thomas Fontaine studied at ISIPCA and worked at Mane and TechnicoFlor before founding the fragrance-creation and consultancy company Pallida. In 2021, after becoming president, he described his work at the conservatory:

Here, I consider myself as a student.

Thomas Fontaine — Essencional, April 6, 2021

Even an experienced perfumer becomes a learner again when encountering earlier work. Knowledge of creation can also pass down through smelling completed perfumes. Keeping that opportunity open for future generations is how the Osmothèque connects preservation with education.

Choosing which creations to present as representative also requires judgment. In Giron’s account of preparations for an anniversary event, osmothécaires brought their recommendations and debated which perfumes to select. Their criteria included disappearance from the market, importance to the emergence of modern perfumery, and surviving formulas that supported recompounding. A list of famous names alone cannot communicate perfume history.

As times change, so do the perspectives of those who need preserved scents. In a 2023 account, Anne-Cécile Pouant explained that while the early founders focused mainly on creations from the 1880s to the 1950s, today’s perfumery students visit seeking perfumes from the 1970s. An era once familiar becomes a past that another generation must learn anew.

Preserving older perfumes does not mean rejecting contemporary perfumery. In 2019, Nicolaï observed that restrictions on materials encourage research, and that perfume art evolves as the perfumer’s palette changes. Comparing preserved older creations with current ones reveals not only lost materials but newly available means of expression.

The Public Can Experience Preserved Scents Too

Reading Perfume History Through Blotters

For perfume enthusiasts, entry points include classes, themed events, and guided visits on specified dates. Perfume-history classes combine specialists’ explanations with smelling older perfumes and materials. Comparing scents while hearing their background reveals creative changes that words and photographs alone cannot fully convey.

The experience uses scent strips known as mouillettes. Perfumes from the preservation collection are not applied to skin, nor are portions of liquid taken home. Particular fragrances do not necessarily appear at every session: the subject and available material determine the program.

In 2013, Patricia de Nicolaï said that her time at the Osmothèque was devoted to her audience, continuing:

I want THEM to be exalted by the perfumes they discover.

Patricia de Nicolaï — Interview with Sergey Borisov for Fragrantica, 2013

This explains why preservation’s results extend beyond specialist research. Some visitors seek a perfume they once wore; others encounter a creation they previously knew only by name. Personal memory and perfume history meet in the same place.

The Current Location and How to Book

In September 2025, the Osmothèque moved from its previous base at ISIPCA to 8 rue Saint-Simon in central Versailles. Official information and booking pages checked on October 14, 2026 also give this address.

To participate, choose an event in the official website’s Agenda, then proceed from its individual page to online booking. Events may take place at the Osmothèque or at external museums and cultural venues. Check the date, location, language, and whether attendance is public or restricted to members for each event. Individual visit requests can be discussed through the official contact service.

The following are examples of scheduled events checked on October 14, 2026. Times are local.
