Aldehyde C-11 is a powerful aliphatic aldehyde widely used in perfumery for its fresh, waxy, and citrus-peel character. It provides a sharp, diffusive lift that enhances brightness in fragrance compositions. The material is highly effective at very low concentrations and adds sparkle to floral and aldehydic accords. It contributes a clean yet slightly fatty nuance that supports classic and modern perfumes. Aldehyde C-11 is commonly used in fine fragrances, soaps, detergents, and functional products.
