CAS: 18127-01-0
Bourgeonal, chemically known as 3-(4-tert-butylphenyl)-2-methylpropanal or 4-tert-butyl-alpha-methylhydrocinnamaldehyde (CAS: 18127-01-0), is a synthetic aromatic aldehyde. It is renowned for its strong, fresh, floral, green, and lily-of-the-valley scent profile, often described as cyclamen-like. Its molecular formula is C14H20O. Bourgeonal gained scientific interest for its specific interaction with the human olfactory receptor OR17-4, which is also expressed on human sperm, playing a role in sperm chemotaxis.
It is widely used as a fragrance ingredient in the perfumery and cosmetics industries. Its characteristic scent makes it valuable for creating floral, green, and fresh accords. It is also utilized in research due to its specific interaction with olfactory receptors and its involvement in sperm guidance mechanisms.
Bourgeonal is applied in the formulation of fine fragrances (perfumes and colognes), personal care products (soaps, shampoos, lotions), and household products (detergents, air fresheners) to impart its distinctive floral aroma. In scientific research, it serves as a ligand for studying olfactory receptor function and investigating human sperm chemotaxis and fertilization processes.
Bourgeonal is recognized as a potential contact allergen and can cause skin sensitization in susceptible individuals. It is listed as an allergenic fragrance ingredient under EU cosmetic regulations, requiring declaration on product labels when exceeding certain concentrations. General handling precautions for chemicals, such as avoiding direct skin/eye contact and ensuring adequate ventilation, should be followed.
