Aldehyde C12 (MNA)
Aldehyde C12 (MNA)
Aldehyde C12 (MNA), also known as Methylnonylacetaldehyde, is a long-chain fatty aldehyde valued in perfumery for its fresh, waxy, citrus-floral scent with soft green nuances. Compared to Aldehyde C10 (Decanal) and Aldehyde C12 Lauric, Aldehyde C12 (MNA) offers a cleaner, more diffusive character, making it essential for aldehydic florals, chypres, and fresh compositions.
It acts as a top-note enhancer, giving sparkle, airiness, and lift to perfumes. Often used in trace amounts, Aldehyde C12 (MNA) blends beautifully with Bergamot Essential Oil, Neroli Essential Oil, Rose Essential Oil, White Musk Perfume Oil, and woody notes. It’s the backbone of many timeless floral aldehydic perfumes, creating that iconic “sparkling-clean” effect with creamy depth.
