Lyral(CAT: R038474), also known as Hydroxyisohexyl 3-cyclohexene carboxaldehyde, is a synthetic fragrance compound composed of a mixture of isomeric forms. Characterized by a fresh, floral, lily-like scent, Lyral is widely used in the formulation of perfumes, cosmetics, soaps, and personal care products. Its chemical structure features a substituted cyclohexene ring with an aldehyde functional group, contributing to its distinctive olfactory profile. Although effective in enhancing fragrance complexity, its use has been restricted in some regions due to allergenic concerns. Lyral remains of interest in fragrance chemistry studies and is used in regulatory testing and formulation benchmarking for allergen-free alternatives.
