Cinnamaldehyde CAS #104-55-2

Cinnamic aldehyde is used as a flavoring agent, ingredient of fragrance in soft drinks, ice creams, dentifrices, pastries, chewing-gum, etc. It can induce both contact urticaria and delayed-type reactions. It can be implicated in contact dermatitis in those who work in the perfume industry or food handlers. Cinnamic aldehyde is contained in the “fragrance mix”.

Cinnamaldehyde is a pale yellow to yellow-green oily liquid with a strong pungent, spicy, cinnamon odor. It is generally insoluble in water and many organic solvents, but is miscible with alcohol and other flavoring oils. Exposure to air will cause thickening and oxidation.
