Biotransformation cinnamyl esters

Cinnamyl acetate is an organic compound that belongs to the class of esters, specifically the acetate esters of cinnamyl alcohol. It is a colorless liquid that is found naturally in various plants and is commonly used in the flavoring and perfumery industries due to its sweet, floral, and slightly balsamic aroma, reminiscent of cinnamon and cloves. Cinnamyl acetate is used to impart fragrance in cosmetics and to flavor food and beverages.

Properties

Cinnamyl acetate has the chemical formula C₁₁H₁₂O₂ and a molecular weight of 176.21 g/mol. It is slightly soluble in water but highly soluble in organic solvents such as ethanol and diethyl ether. The compound has a boiling point of approximately 265°C and a density similar to that of water.

Synthesis

Cinnamyl acetate can be synthesized through an esterification reaction, where cinnamyl alcohol is reacted with acetic acid or acetic anhydride in the presence of a strong acid catalyst such as sulfuric acid. This process typically involves heating the reactants and continuously removing the water formed during the reaction to drive the equilibrium towards the formation of the ester.

Applications

Flavoring Agent

Due to its sweet and balsamic aroma, cinnamyl acetate is widely used as a flavoring agent in food and beverages. It is often found in confectionery, baked goods, and alcoholic beverages, where it adds a hint of cinnamon and spice.

Fragrance

In the perfumery industry, cinnamyl acetate is valued for its floral and spicy notes. It is used in the formulation of perfumes, colognes, and other scented products, including soaps, lotions, and candles.

Cosmetics

Beyond its use in perfumery, cinnamyl acetate is also used in cosmetics for its fragrance. It can be found in products such as shampoos, conditioners, and body washes.

Safety

Cinnamyl acetate is generally considered safe for use in both food and cosmetic products. However, like many fragrance ingredients, it can cause allergic reactions in some individuals when applied topically. It is always recommended to conduct a patch test before using a new product containing cinnamyl acetate on the skin.

Environmental Impact

While cinnamyl acetate is not known to be a major environmental pollutant, its production and use should still be managed to minimize any potential environmental impact. Proper handling and disposal procedures should be followed to prevent unnecessary release into the environment.
