At the World Perfumery Congress 2026, taking place at the Monterey Conference Center in Monterey, California, from June 23 to 25, Cosmo International Fragrances introduces The Mood Lab — a new approach to perfumery in which ingredients act as catalysts for mood. Built on over eight years of research in collaboration with neuropsychiatrist and biochemist Dr. Olga Alexandre, the project bridges olfactotherapy and neuroscience to better understand how scent interacts with the brain. Through controlled studies combining physiological and psychological measurements, the findings demonstrate that specific natural ingredients can influence key mental states, including focus, relaxation, energy, and confidence. The Mood Lab serves as COSMO’s platform for translating mood-tested ingredients into fragrance experiences designed around specific emotional and cognitive states. Moving beyond traditional perfumery, where fragrance is primarily described through olfactive notes, this approach redefines ingredients as true drivers of perception and experience. Each material is selected not only for its scent profile, but for its measured impact on the mind— transforming creation into a new territory between intuition and scientific validation. At the heart of The Mood Lab, COSMO presents a collection of nine exclusive natural ingredients, each linked to a distinct mood profile. From energizing Ginger Peru CO₂ to focus-enhancing Petitgrain Lime Colombia and confidence-boosting Vanilla CO₂ Extract, these ingredients serve as the foundation for the fragrances featured throughout the platform. Extending this vision, COSMO introduces The Catalyst Collection—a series of fine fragrances conceived as dynamic systems, where the interaction of ingredients triggers specific emotional pathways while leaving room for personal interpretation and memory. Through these compositions, fragrance moves beyond emotional storytelling toward a more intentional approach to fragrance design. The company will also showcase AquaElixir™, its water-based technology for alcohol-free fragrances, demonstrating its commitment to sustainable innovation and next-generation fragrance formats. “With The Mood Lab, we treat ingredients not just as scents, but as catalysts,” says Anne-Laure André, Project Manager of the Natural Ingredients Division. “By linking molecular composition to measurable effects on the mind, we are opening a new chapter in perfumery—where creation meets proof.” Visitors are invited to discover this new olfactory paradigm at Booth 302, where scent becomes a functional, measurable, and deeply personal experience.
