Hedione

A light, diffusive jasmine aroma chemical first used in Diorissimo (1962). Activates a specific olfactory receptor associated with dopamine response, and one of perfumery's most widely used materials.

Methyl dihydrojasmonate (C₁₃H₂₂O₃). A synthetic jasmine odorant first isolated in 1958 by Edouard Demole at Firmenich, and brought to fine fragrance by Edmond Roudnitska in Dior's Eau Sauvage (1966). Characterized by a light, diffusive, jasmine-floral odor with aquatic and green nuances and exceptional substantivity relative to its perceived freshness. Identified as a ligand for VN1R1, a putative pheromone receptor expressed in the human olfactory mucosa, whose activation produces sex-differentiated brain responses not seen with ordinary floral odorants. One of the most widely used aroma chemicals in fine fragrance by volume.
