Catherine Poensin-Stefani
Catherine Poensin-Stefani is a senior perfumer at Symrise, one of the world's largest fragrance houses, where she works from the company's Paris creative center. With decades of professional experience in fine fragrance creation, she represents a generation of perfumers who shaped modern composition through hands-on laboratory work and client collaboration rather than public-facing celebrity. Based in Paris, she sits within the creative teams that develop fragrances alongside major brands and independent houses across Europe and beyond. In a rare paired conversation published by Symrise, she appeared alongside fellow perfumer Alexandra Carlin to discuss how individual raw materials can shift a formula's character. Her career path through the industry's technical ranks, training in raw material evaluation and formula construction, places her among the experienced noses who mentor incoming talent at major ingredient suppliers. At 68, she continues working actively from the French capital, contributing to Symrise's creative output in a city long considered the nerve center of Western perfumery.

How Catherine composes
Trained in the classical French tradition of formula construction, Catherine Poensin-Stefani builds compositions with an editor's sensibility, layering materials to find the balance where each note supports the whole. Her work at Symrise places her at the intersection of natural ingredients and synthetic molecules, allowing access to both traditional bases and modern captives that expand the perfumer's palette. Working from Paris, she benefits from proximity to the historic French ingredient trade and Symrise's global sourcing network. Her paired discussion with Alexandra Carlin highlighted how a single unexpected element, sometimes borrowed from outside fine fragrance, can redirect a formula's mood. This willingness to import techniques and materials across categories defines her technical approach, treating each brief as an opportunity to question conventional structure.
Philosophy
What drives Catherine
Catherine Poensin-Stefani approaches creation with the patience of someone who has spent a career inside a major fragrance house, surrounded by thousands of raw materials and constant collaboration. She treats perfumery as a craft built on iteration, where small adjustments to a single ingredient can reshape how an entire composition is perceived. Her perspective emphasizes the practical dialogue between perfumer and material, acknowledging that each molecule carries associations, textures, and emotional cues that the nose must learn to read. Working within Symrise's creative structure, she values the cross-pollination between fine fragrance and adjacent categories like personal care, where ingredient innovation often originates. Her conversations with colleagues suggest a belief that fragrance is built through listening to materials as much as directing them, a humility that comes from sustained professional practice.
