Aldehydes are organic compounds that are present in various natural materials, such as rose, citronella, cinnamon bark, and orange rind, and are also a family of synthetic chemicals formed by the partial oxidation of primary alcohols. They are used in perfumery to boost the "whoosh" of a fragrance, making it sparkle and effervesce. Aldehydes are classified into different types based on their molecular weight and smell, such as metallic, starchy, citrusy, waxy, and soapy. Some of the most widely used aldehydes in perfumery are C7 (heptanal), C8 (octanal), C9 (nonanal), C10 (decanal), and C12 (2-methylundecanal) . Aldehydes are also used in the production of dyes, plastics, and pharmaceuticals.
Positive aspects of aldehydes in perfumery include their ability to add a sparkling and effervescent quality to fragrances, as well as their pleasant aromas. Negative aspects of aldehydes include the fact that some lower molecular weight aldehydes can have unpleasant smells, such as the odor of rotten fruit.
Aldehyde C-12 MNA, also known as 2-methylundecanal, is a synthetic aroma chemical with a fresh, amber, aldehydic, mossy, citrus, tuberose, metallic, waxy, and coumarinic scent. It is considered a middle note in perfumery and is often used in fragrance concentrates at a concentration of 2% . Aldehyde C-12 MNA is not restricted for use in fragrances according to the Standards of the International Fragrance Association.
In summary, aldehydes are a family of organic compounds that are used in perfumery to add sparkle and effervescence to fragrances. They are present in natural materials and can also be synthesized. Aldehydes have different molecular weights and smells, and some are more pleasant than others. Aldehyde C-12 MNA is a synthetic aroma chemical with a fresh, amber, aldehydic, mossy, citrus, tuberose, metallic, waxy, and coumarinic scent that is often used in fragrance concentrates.
