Why the Fragrance Houses Kept Their Perfumers Hidden: License and Secrecy

The deepest secret of a perfume is not the scent. It is the formula.

A perfume's formula is not protected by copyright. Scent, the courts have held, is perceived differently by every person, and cannot be fixed in any objective sense. In 2013, the French Cour de cassation ruled, once again, that perfume falls outside the scope of copyright protection. A perfume is not a work. It is a trade secret.

A trade secret loses its protection the moment it is disclosed. And so the fragrance companies conceal the formula. Who composed it. Which molecules went into it. In what proportion they were combined. All of it is held in private. Even inside a fragrance company, the number of people who see a formula in full is small.

This is the structure that produced anonymity.

The twentieth-century perfume industry was built in three layers. The fashion house. The fragrance company. The perfumer. A fashion house commissioned a fragrance company. A perfumer inside the fragrance company composed the scent. The bottle bore the name of the house. Neither the company nor the perfumer ever surfaced.

The arrangement had a commercial logic. From the point of view of the fragrance company, the moment a perfumer's name appeared in public, that perfumer acquired leverage. He could be poached by a competitor. An asset the company had cultivated would walk out the door. Anonymity was, among other things, the mechanism by which the company kept its perfumers in place.

The licensing contracts enforced the same anonymity. A fragrance company does not hand its formula to a fashion house. It supplies the concentrate. The house dilutes the concentrate with alcohol and finishes the perfume from there. Ownership of the formula stays with the fragrance company. The perfumer's absence from the bottle was, in part, a way of leaving open the question of whose perfume it really was.

Cracks began to appear in the twenty-tens. LVMH stopped relying on outside fragrance companies and began building its own perfume facilities. A handful of houses brought perfumers in-house. The four major fragrance companies — Givaudan, Firmenich, IFF, and Symrise — became the subject of a cartel investigation, opened by the Swiss Competition Commission in 2023.

To print a perfumer's name on a bottle, then, is not a simple matter of crediting an author. It is a small fracture in a structure that has been working as designed for a century.

And perhaps even the fracture is, in its own way, the art that perfume makes.
