Cinnamaldehyde, or cinnamic aldehyde, is a member of the class of compounds known as cinnamaldehydes. And it is an oily yellow liquid at room temperature with a boiling point of 246 degrees Celsius.
Cinnamaldehyde can be found in a number of food items such as sour cherry, horseradish, and sea-buckthornberry. And it can be found primarily in feces, as well as in human neuron and skin tissues. it exists in all eukaryotes, ranging from yeast to humans.
Cinnamaldehyde is the aldehyde that gives cinnamon its flavor and odor.
Cinnamaldehyde occurs naturally in the bark of cinnamon trees and other species of the genus Cinnamomum like camphor and cassia. These trees are the natural source of cinnamon, and the essential oil of cinnamon bark is about 90% cinnamaldehyde.
Cinnamaldehyde is also used as a fungicide. Proven effective on over 40 different crops, cinnamaldehyde is typically applied to the root systems of plants. Its low toxicity and well-known properties make it ideal for agriculture. To a lesser extent, cinnamaldehyde is an effective insecticide, and its scent is also known to repel animals like cats and dogs.
Cinnamaldehyde is also known as a corrosion inhibitor for steel and other ferrous alloys in corrosive fluids. It can be used in combination with additional components such as dispersing agents, solvents and other surfactants. Concentrated cinnamaldehyde is a skin irritant, and the chemical is toxic in large doses, but no agencies suspect the compound is a carcinogen or poses a long-term health hazard. Most cinnamaldehyde is excreted in urine as cinnamic acid, an oxidized form of cinnamaldehyde.
