| Hazard Information | Back Directory | [Description]
2-Nonenal has a very powerful, penetrating fatty odor in concentrated form. It is orris-like, waxy, and quite pleasant on dilution. The odor is reminiscent of dried orange peels. Prepared by oxidation of 9,10,12-trihydroxy stearic acid (Criegee reaction). | [Chemical Properties]
2-Nonenal has a very powerful, penetrating, fatty odor in concentrated form. The odor is orris-like, waxy and quite
pleasant on dilution. The odor is also reported as reminiscent of dried orange peels | [Occurrence]
Reported found in orris oil, melon, peach, asparagus, carrot, peas, tomato, wheat and crisp breads, Russian
cheeses, caviar, butter, fish oil, cooked beef, mutton, pork, and their fats, hop oil, cognac, roasted filberts and peanuts, soybean, beans,
sesame seed, mango, rice, beer, and potato chips | [Uses]
The concentration in a perfume oil may be of the order of magnitude of 0.01 to 0.03%. An addition of 0.02% of 2-Nonenal to a normal grade of "gamma" -Methylionone will produce a distinctly ("orrisy") perceptible effect, desirable and attractive in the opinion of many perfumers.
