Description

10-Methylundecanal is a high-purity aliphatic aldehyde of significant interest in the fragrance and flavor industry. Its value lies in its unique olfactory profile, contributing fresh, citrusy, and waxy-green notes that are essential for creating complex aromatic compositions. This compound is primarily needed by perfumers and flavorists for use in fine fragrances, personal care products, and specialty food flavorings.

Application

• Fragrance Formulation: A key ingredient in fine perfumery, imparting fresh, aldehydic, citrus, and waxy nuances to floral, chypre, and fougère accords.
• Flavor Creation: Used in specialty flavorings to provide citrus, mandarin, and fresh green notes for beverages, confectionery, and dairy products.
• Personal Care Products: Incorporated into soaps, shampoos, lotions, and detergents to provide a fresh, clean, and long-lasting scent profile.
• Household & Industrial Fragrances: Employed in air fresheners, cleaning agents, and fabric softeners for its potent and diffusive character.
• Aroma Chemical Intermediate: Serves as a valuable building block for the synthesis of more complex fragrance molecules and derivatives.
